Repurposed drugs may offer improved treatments for fatal genetic disorders
Wednesday, December 21, 2016
Department of Biomedical Genetics researchers believe they have identified a new means of treating some of the most severe genetic diseases of childhood, according to a new study in PLOS Biology. The diseases, called lysosomal storage disorders (LSDs), are caused by disruptions in the functioning of the stomach of the cell, known as the lysosome. LSDs include Krabbe disease, Gaucher disease , metachromatic leukodystrophy and about 40 related conditions. In their most aggressive forms, they cause death of affected children within a few years after birth.
The research was spear-headed by Nicole Scott-Hewett and Chris Folts, two recent graduates of the program in Genetics, Development and Stem Cells. Led by the article's corresponding author Mark Noble, Ph.D., the team discovered for the first time how specific toxic waste products that accumulate in LSDs cause multiple dysfunctions in affected cells. They also found that several drugs already approved for other uses have the unexpected ability of overcoming the cellular toxic build-up, providing new opportunities for treatment. Key to this discovery was the finding that these drugs can help restore normal acidification of the lysosome.
In a mouse model of Krabbe disease (one of the most severe LSDs), Drs. Folts and Scott-Hewett found that their lead study drug, colforsin, increased survival as effectively as in studies where disease-causing mutations were corrected by gene therapy. Colforsin is approved in Japan to treat cardiac disease, which provides information to investigators about its use in humans.
Increased survival in mice occurred even though treatment was started later than is necessary for gene therapy. The research treatment also decreased damage to the brain and improved the quality of life in the diseased mice. All of these outcomes are critical goals in the treatment of children with Krabbe disease or related illnesses, said Noble, who is the Martha M. Freeman, M.D., Professor in Biomedical Genetics at URMC.
"One of the great challenges in these diseases is that they are both rare and come in many different varieties, and advances have tended to focus on single diseases," Noble said. "In contrast, our findings suggest our treatments will be relevant to multiple disorders. Also, we saw benefits of our treatment even without needing to correct the underlying genetic defects. That gives us great hope that we could combine our treatments with other candidate approaches to gain additional benefits."
If the results can be translated into humans, Noble said, the repurposed drugs might improve the quality of life for afflicted children while more difficult experimental genetic treatments are pursued. The complete study can be found at: PLoS BiologyRead More: Repurposed drugs may offer improved treatments for fatal genetic disorders

Research Led by Hucky Land Points to Prostate Cancer Tool
Tuesday, December 20, 2016
Researchers from Wilmot Cancer Institute and Roswell Park Cancer Institute in Buffalo reported in the journal Oncotarget that they have discovered a possible new tool for predicting whether prostate cancer will reoccur following surgery based on the expression patterns of four genes.
The Wilmot/Roswell Park tool was able to predict recurrence, based on human tissue samples and known patient outcomes, with 83 percent accuracy. Currently the only other way to estimate tumor aggressiveness is with a Gleason score, a grading system for prostate tumors that has limited power in most cases, researchers said.
Some prostate cancers grow very slowly, and when the disease is detected early, the five-year survival rates are nearly 100 percent. However, some men are diagnosed with more aggressive localized disease and, even after having a radical prostatectomy, cancer will return in one-third of patients.
“Our study sought to improve upon the prediction tools used in these types of cases so that oncologists would know with more certainty when to recommend additional treatment, such as radiotherapy, immediately after surgery,” said Hucky Land, Ph.D., director of research at Wilmot and the Robert and Dorothy Markin Chair of the Department of Biomedical Genetics, who led the research. (Most patients receive no further treatment after surgery.)
Earlier, Land’s lab discovered a large group of non-mutated genes that are actively involved in cancer development. After analyzing expression of this gene set in frozen prostate cancer tissue samples, researchers discovered the four-gene signature, which was expressed differently in prostate cancer that later returned. Justin Komisarof, an M.D./Ph.D. student in the Land lab, developed the various algorithms and methods to evaluate the gene signature. The research team concluded that their tool outperformed other scientific methods, and they have applied for a U.S. patent.
The National Institutes of Health and Wilmot Cancer Institute/Roswell Park Cancer Institute Collaboration Pilot Funds supported the research. Chief collaborators from Roswell Park include Carl Morrison, M.D., executive director of the Center for Personalized Medicine, and James Mohler, M.D., associate director and senior vice president for translational research at Roswell.

Jimmy Zhang, Awarded Two-year American Heart Association Predoctoral Fellowship

Jimmy Zhang, graduate student in the laboratory of Dr. Paul Brookes was awarded a two-year American Heart Association predoctoral fellowship entitled,
“The Development of Novel Acute Myocardial Infarction Therapeutics Using Metabolomics and High-Throughput Screening” beginning January 1, 2017.
Paradoxically, current AMI therapies have the common goal of promoting reperfusion and, in doing so, trigger events that lead to cell death. As a result, there is a need for new therapeutics that limit reperfusion-induced injury.
Many of the pathologic cellular events of reperfusion-induced injury can be attributed to maladaptive metabolic remodeling. One particular metabolite of interest is succinate, which accumulates during ischemia. Upon reperfusion, succinate is consumed in the electron transport chain by Complex II, generating reactive oxygen species at Complex I. This reverse electron transport (RET) appears to be a major contributor to IR injury. Yet, despite the relevance of RET to IR injury, the pathway of succinate accumulation has yet to be elucidated. Additionally, succinate accumulation during ischemia might contribute to the generation of the mitochondrial membrane potential by permitting Complex I activity. This membrane potential can then be used for functions such as membrane transport and maintenance of redox status.
In our preliminary data, nornicotine was identified as a potentially cardioprotective candidate, and was shown to inhibit Complex I activity. Inhibition of RET could be the mechanism of protection by nornicotine. Using high-throughput screening and metabolomic approaches, this project will determine whether inhibition of RET is a rapid metabolic adaptation that is conserved across cardioprotective strategies (nornicotine treatment, ischemic preconditioning, and ischemic postconditioning). Finally, the pathway and function of succinate accumulation will be investigated by measuring membrane potential and redox status in isolated mitochondria.
Overall, this project aims to investigate RET in IR injury with the goal of developing novel therapeutics for AMI.

Researchers Identify Brain Region as Possible Target for Dementia Prevention
Tuesday, December 13, 2016
A University of Rochester study has found that older adults with excellent memories have more efficient connections between specific areas of the brain — findings that could hold promise for the prevention of dementia and cognitive decline.
Although researchers have historically viewed memory deterioration as an inevitable part of the aging process, a small group of older adults — called “supernormals” — are able to maintain their memory capacities much better than their peers. Feng (Vankee) Lin, PhD, an assistant professor in the University of Rochester School of Nursing, is spearheading a new approach to the study of Alzheimer’s disease by exploring what can be learned from these individuals.
In a study on the topic published in Cortex, an international journal devoted to the study of cognition and the relationship between the nervous system and mental processes, Lin and her team explored differences in brain function among three groups of older adults: supernormals, who were defined as having higher than average memory scores for their age, older adults diagnosed with amnestic mild cognitive impairment who are at high risk for developing Alzheimer’s disease, and a healthy control group. The study is the first to compare the brain function of supernormals to those who are at risk for developing Alzheimer’s.Read More: Researchers Identify Brain Region as Possible Target for Dementia Prevention

University Research Award helps team explore regeneration in a critical layer of the cornea
Friday, December 9, 2016
The structure of the cornea.
(Keratomania.com eye diagram by
Chabacano,via Wikimedia Commons.)
On the backside of the cornea is a single layer of cells that plays an all-important role, maintaining just the right fluid balance to keep the cornea transparent so that light can enter the eye. Until recently, it was believed this layer, called the corneal endothelium, is incapable of replacing its damaged cells. As more cells become damaged, the cornea becomes opaque, leading to loss of vision and, ultimately, to as many as 30,000 endothelium transplants a year in the United States alone.
A team of University researchers is exploring the possibility that stem cells on the outer edges of the cornea, given the right stimulation, can migrate into the endothelium to replace damaged cells. (Undifferentiated stem cells develop into specialized cells.) The work raises the possibility of restoring vision without the need for transplants.
The team is led by Amy Kiernan, associate professor of ophthalmology, and includes Jannick Rolland, the Brian J. Thompson Professor of Optical Engineering; Patrice Tankam, a senior scientist in the Center for Visual Science; Changsik Yoon, a graduate student in Rolland’s lab; Rebecca Rausch, a graduate student in Kiernan’s lab; and Holly Hindman, former associate professor of ophthalmology, now in private practice but still consulting on the project. They are supported with a $75,000 University Research Award. The URA program is designed to help researchers develop preliminary data or proof of concept needed to leverage larger federal or foundation awards to carry a promising project to completion.
There have been tantalizing clinical hints that the corneal endothelium may have regenerative capabilities, Kiernan says. For example, there have been cases in which endothelial transplants failed to engraft, but the cornea cleared up anyway, with regeneration of the endothelium occurring on its own. “So it seems that if something is done that stimulates a progenitor or stem cell population, most likely those in the periphery of the cornea, there is some regenerative capacity in the endothelium – just based on clinical studies,” Kiernan says.
Her team will attempt to identify the potential stem cells that might be stimulated to migrate to the endothelium to repair damage. They will use mouse models from Kiernan’s lab in which adult stem cells can be permanently tagged with fluorescent biomarkers and tracked even after they differentiate into other cells. The identification and tracking of those cells will be done by refining a novel imaging approach developed in Rolland’s lab. Called Gabor domain optical coherence microscopy, the technology allows rapid, noninvasive imaging of cellular structures beneath the surface of the skin or within the human eye – in greater detail than traditional imaging with optical coherence tomography.
“Think of it as a high-definition, volumetric imaging,” Rolland says. “But we also want to know what kind of cells we are looking at, so we are integrating fluorescence imaging with the high-definition volumetric microscopy so we can do both.” The team represents a combination of pertinent expertise: cell development and regeneration (Kiernan and Rausch), imaging (Rolland, Tankam, and Yoon), and the biological basis for corneal and ocular surface diseases in humans (Hindman). The University Research Award funding is helping support graduate students and technicians working on the project, and the cost of mice and supplies. “Pilot funding like this is so important, especially with NIH grants shrinking,” Kiernan says.
“It’s really helpful to be able to bridge this kind of interdisciplinary effort,” says Rolland. “You need to work together a little bit to understand the challenges involved and what you need to do to secure preliminary data, to show we have a pathway.
“It takes time to get data, so even a small grant that provides a bridge for a year or two can make a huge difference.”
Nina Schor to Step Down as Children's Hospital Pediatrician-in-Chief
Wednesday, December 7, 2016
Nina Schor, M.D., Ph.D., William H. Eilinger Chair of Pediatrics at the University of Rochester Medical Center (URMC), will step down as chair in June 2017. Schor served 11 years as pediatrician-in-chief at UR Medicine’s Golisano Children’s Hospital, and under her leadership, the Department of Pediatrics fulfilled a decades-long dream of building a standalone children’s hospital in Rochester; the new facility opened its doors to patients in July 2015. "I don’t want to downplay the significance of the new hospital, but it’s really what we do inside of it and because of it that’s so important,” said Schor. “I look at the academic physicians and physician scientists who came to Rochester with just a dream and a fire in their belly and how they’ve now brought those dreams to fruition — that’s what I’m most proud of.”
The Department of Pediatrics grew from 110 faculty members to over 170 during Schor’s tenure, creating new divisions in palliative care, sleep medicine, allergy, and hospitalist medicine. Research centers focused on premature infants, translational molecular programs, and red blood cell development also developed under Schor’s leadership.
“Not only was the new hospital built under Nina’s leadership, but she truly championed the project, ensuring that every detail was designed with patients and families in mind,” said Mark Taubman, M.D., URMC CEO and Dean of the School of Medicine and Dentistry. “She has been the face of the children’s hospital and inspired trust in our families, physicians, and donors at a time when we very much needed the community’s support.”Read More: Nina Schor to Step Down as Children's Hospital Pediatrician-in-Chief

Brain training video games help low-vision kids see better
Monday, November 28, 2016
Studies going back several years have shown that playing action video games (AVG) can help improve visual acuity. A new study by vision scientists at the University of Rochester and Vanderbilt University found that children with poor vision see vast improvement in their peripheral vision after only eight hours of training via kid-friendly video games. Most surprising to the scientists was the range of visual gains the children made, and that the gains were quickly acquired and stable when tested a year later.
“Children who have profound visual deficits often expend a disproportionate amount of effort trying to see straight ahead, and as a consequence they neglect their peripheral vision,” said Duje Tadin, associate professor of brain and cognitive sciences at Rochester. “This is problematic because visual periphery—which plays a critical role in mobility and other key visual functions—is often less affected by visual impairments.”
“We know that action video games (AVG) can improve visual perception, so we isolated the AVG components that we thought would have the strongest effect on perception and devised a kid-friendly game that compels players to pay attention to the entire visual field, not just where their vision is most impaired,” said Tadin, who is also a professor in the Center for Visual Science. “As a result, we’ve seen up to 50 percent improvement in visual perception tasks.”Read More: Brain training video games help low-vision kids see better

‘Antisense’ compounds offer new weapon against influenza A
Thursday, November 17, 2016
Challenging a long-held convention, University researchers have shown they can inhibit the influenza A virus by targeting its genomic RNA with “antisense” compounds.
Their findings, highlighted on the cover of Nucleic Acid Therapeutics, offer scientists a new way to attack an increasingly drug-resistant pathogen that causes an estimated 250,000 to 500,000 deaths a year.
“Antisense” compounds are synthesized with nucleotides, the building blocks of nucleic acid, often shown as various combinations of A, U, G and C. When the compounds – called antisense oligonucleotides (ASOs) – bind to the targeted genomic RNA, they block its ability to replicate.
The collaboration, involving the labs of Douglas Turner, professor of chemistry; Luis Martinez-Sobrido, associate professor of microbiology and immunology; and two researchers in Poland, reported that “antisense” compounds targeting one of the virus’ eight genomic RNA segments caused a five- to 25-fold reduction of influenza A virus in cell cultures.
“That’s a big difference,” Martinez-Sobrido says. “When mice are infected with 10,000 viruses, they all die. However, with 25 times less virus, all animals can survive infection and they don’t even develop symptoms.”

Wilmot Cancer Institute’s co-directors Hartmut “Hucky” Land, Ph.D., and David C. Linehan, M.D., were recognized recently with the Davey Award, an honor bestowed on University of Rochester faculty members who have made outstanding contributions to cancer research.
They received their awards at the 21st annual Wilmot Scientific Symposium Nov. 10. The award for Land, who organizes the annual symposium, was a surprise orchestrated by Jonathan W. Friedberg, M.D., M.M.Sc., director of Wilmot Cancer Institute.
At the symposium, Land presented the planned Davey Award to Linehan, who is also Wilmot’s director of clinical operations and the Seymour I. Schwartz Professor and Chairman of Surgery. Linehan was recognized for his work studying the role of the tumor microenvironment in promoting treatment resistance in pancreatic cancer.
Before his lecture, Linehan presented Land the surprise award with a recorded video message from Friedberg. Land, who is also Wilmot’s director of research and the Robert and Dorothy Markin Professor of Biomedical Genetics, was recognized for his body of work and for his work studying the genetic programs that control all of cancer’s worst shared features — such as a cancer cell’s ability to quickly divide and survive despite aggressive treatment.
Repurposed Drug May Offer Diagnosis, Treatment for Traumatic Nerve Damage
Monday, November 14, 2016
Researchers at the University of Rochester Medical Center believe they have identified a new means of enhancing the body’s ability to repair its own cells, which they hope will lead to better diagnosis and treatment of traumatic nerve injuries, like those sustained in car accidents, sports injuries, or in combat. In a study published today, the team showed that a drug previously approved for other purposes can ‘wake up’ damaged peripheral nerves and speed repair and functional recovery after injury.
The study appearing in EMBO Molecular Medicine, demonstrates for the first time that 4-aminopyridine (4AP), a drug currently used to treat patients with the chronic nerve disease, multiple sclerosis, has the unexpected property of promoting recovery from acute nerve damage. Although this drug has been studied for over 30 years for its ability to treat chronic diseases, this is the first demonstration of 4AP’s benefit in treating acute nerve injury and the first time those benefits were shown to persist after treatment was stopped.
Study authors, John Elfar, M.D., associate professor of Orthopaedics, and Mark Noble, Ph.D., Martha M. Freeman, M.D., Professor in Biomedical Genetics, and their laboratory team, found that daily treatment with 4AP promotes repair of myelin, the insulating material that normally surrounds nerve fibers, in mice. When this insulation is damaged, as occurs in traumatic peripheral nerve injury, nerve cell function is impaired. These researchers found that 4AP treatment accelerates repair of myelin damage and improvement in nerve function.Read More: Repurposed Drug May Offer Diagnosis, Treatment for Traumatic Nerve Damage
Catherine Ovitt Featured in D&C's Hot Jobs
Sunday, November 13, 2016
Dr. Catherine Ovitt
Salivary glands, which make as much as a quart of saliva each day, don’t pose a life-threatening risk if they stop working properly. But given their roles — they are important for swallowing, keep the inside of your mouth moist so your cheeks can move around, and have both anti-fungal and anti-bacterial properties — a malfunction would greatly impact quality of life.
Medical scientist Catherine Ovitt has dedicated her career to the study of salivary glands, in particular to establishing therapeutic strategies for their repair or regeneration after damage from radiation treatment due to head and neck cancers, or because of cellular damage from autoimmune diseases.
“A long-term goal would be to develop some sort of cell therapy treatment, some kind of transplantation or artificial salivary gland,” said Ovitt, who lives in Pittsford and is an associate professor in the Center for Oral Biology, part of UR Medicine’s Eastman Institute for Oral Health. Without the glands, she added, “you end up losing all your teeth.”Read More: Catherine Ovitt Featured in D&C's Hot Jobs

Thomas Mariani Authors Study on Infant Nose, Lung Cells
Thursday, October 13, 2016
Cells from an infant’s nose are remarkably similar to those found in the lungs, a discovery that could lead to much more precise diagnosis of respiratory syncytial virus (RSV) and other infant lung diseases, according to new URMC research.
The study, published in Scientific Reports, provides a potential avenue for diagnosis that has challenged physicians for years, as infants with respiratory disease are usually so fragile that attempting to obtain lung samples is unsafe. Nasal cells, however, can be captured through a simple swab of the nostril, and their similarity to lung cells on an RNA level would allow physicians to get an accurate representation of how the lung is responding during disease states, without the need for more invasive tests.
“An infant with RSV could potentially have their nasal cells tested to determine if they are among the small group that will develop a severe response that might require hospitalization,” said Thomas Mariani, Ph.D., professor of Pediatrics and the study’s lead author. “Additionally, we could potentially use this method to examine other at-risk infants, such as those born prematurely who face a greater risk for lung disease throughout life — and identify which of those children should be treated more aggressively.”
The research also carries tremendous promise for future studies. While scientists have made significant progress over the past several decades to better understand adult lung diseases — such as chronic obstructive pulmonary disease and lung fibrosis — discovery has not been nearly as robust for infant diseases, due to the risks involved in securing lung tissue.
But the relative ease of obtaining nasal cells could accelerate understanding of how infant lungs respond to RSV and other diseases. While this study examined 53 healthy infants as a means of establishing a benchmark for normal cell structure, researchers at URMC have already begun studying the nasal tissue of diseased infants. Early results are promising.
“We’re actively working on studies in infants with lung diseases, and we’re showing quite clearly that we can identify differences between those with mild disease and those with more severe outcomes,” Mariani said.
The research is conducted by URMC’s Respiratory Pathogens Research Center, which coordinates its work with the national Respiratory Pathogens Research Center established by the National Institute of Allergy and Infectious Diseases. The Center, under the direction of David Topham, Ph.D., focuses on research that will lead to a better understanding of the interactions between respiratory pathogens, the immune system, and other genetic and environmental factors.
ChinYi Chu, M.S., Xing Qiu, Ph.D., Lu Wang, M.S., Soumyaroop Bhattacharya, M.S., M.Ed., Gerry Lofthus, Ph.D., Anthony Corbett, M.S., Jeanne Holden-Wiltse, M.S., Alex Grier, M.S., Brenda Tesini, M.D., Steve Gill, Ph.D., Ann Falsey, M.D., Mary Caserta, M.D., and Ed Walsh, M.D., from the University of Rochester, contributed to these studies.

Research Will Explore New Therapies for Huntington's Disease
Wednesday, October 12, 2016
A new award from the CHDI Foundation will advance promising research that aims to slow the progression of Huntington’s disease. The funding, anticipated to total more than $10.5 million over next five years, will help University of Rochester Medical Center (URMC) scientists develop a stem cell-based therapy that swaps sick brain cells for healthy ones.
The new award will go to the lab of Steve Goldman, M.D., Ph.D., the co-director of the URMC Center for Translational Neuromedicine, which has research operations in both Rochester and at the University of Copenhagen.
Huntington’s is a hereditary neurodegenerative disease characterized by the loss of medium spiny neurons, a nerve cell in the brain that plays a critical role in motor control. As the disease progresses over time and more of these cells die, the result is involuntary movements, problems with coordination, and cognitive decline, depression, and often psychosis. There is currently no way to slow or modify this fatal disease.
The new award will support research that builds upon findings published by Goldman earlier this year in the journal Nature Communications showing that researchers were able to slow the progression of the disease in mice by transplanting healthy human support cells, called glial progenitor cells, into the animals’ brains.Read More: Research Will Explore New Therapies for Huntington's Disease
Wilmot Scientists Exploit Cell Metabolism to Attack Cancer
Wednesday, October 12, 2016
Cancer cells have their own unique ways of reproducing, involving a shrewd metabolic reprograming that has been observed in virtually all types of cancer but not in normal cells. Now, University of Rochester Medical Center scientists have pinpointed one key source of the problem, which could lead to new treatment opportunities.
In an article published by Cell Reports, the scientific team shows for the first time how cancer-causing mutations control and alter the way cancer cells biosynthesize and replicate.
The discovery is the result of a close collaboration between the laboratories of Joshua Munger, Ph.D., associate professor of Biochemistry and Biophysics, and Hucky Land, Ph.D., the Robert and Dorothy Markin Professor and Chair of Biomedical Genetics and director of research at the URMC’s Wilmot Cancer Institute.
“Every tissue or cell type in the body has different metabolic needs but as cells become cancerous their metabolism shifts in ways that are very different from normal cells,” Munger said. “Being able to identify those differences is critical for developing treatment targets.”Read More: Wilmot Scientists Exploit Cell Metabolism to Attack Cancer
Armond Collins Presents his work from Fudge Lab
Tuesday, October 11, 2016
Armond Collins, a second year medical student, presents the study he conducted with us this summer under the auspices of a Babigian Fellowship. Armond studied changes in myelination in amygdala and cortex of adult rats that had been exposed to 3 day bout of a repeated variable stressor during adolescence. His works follows up studies by Michele Saul, PhD that indicate that adolescent stress results in decreased oligodendrocyte precursors in the amygdala in the week following the stress.
NIH Director Visits URMC, Says it’s an Exciting Time to be a Researcher
Monday, October 10, 2016
Collins’ first stop was lunch with 15 graduate students and postdocs who came prepared with a wide range of questions. The discussion covered the importance of communicating science to the public and policymakers, increasing diversity in biomedical research and new mechanisms to support young scientists at the start of their careers. Postdoctoral fellow Sarah Latchney and Ph.D. graduate student Solomon Abiola attended the lunch with Collins and describe the experience here.
Members of the Center for RNA Biology highlighted their most promising work for Collins and Center director Lynne E. Maquat, Ph.D., gave Collins a tour of her lab, where he met more trainees and junior researchers (admittedly, Collins’ favorite part of visits like these).
In his keynote address at the end of the day, Collins delivered an uplifting message to a packed house in the Class of ’62 auditorium: it is an extremely exciting time to be in biomedical research, and after many lean years we are turning a corner, with the NIH budget finally increasing in real terms. He detailed several of the NIH’s new programs, like the Human Microbiome Project, Big Data to Knowledge (BD2K), the Precision Medicine Initiative and the Cancer Moonshot.
He applauded URMC on the renewal of the CTSI funding and cited the translational research conducted by Arthur J. Moss, M.D., which has led to new treatments for patients with Long QT syndrome (LQTS), and John J. Treanor, M.D., which is helping scientists in pursuit of a universal flu vaccine.

New Grants Explore Role of Brain’s “Garbage Truck” in Mini-Stokes and Trauma
Wednesday, October 5, 2016
Maiken Nedergaard, M.D., D.M.Sc.
More than $4.5 million in new grants to the lab of University of Rochester Medical Center scientist Maiken Nedergaard, M.D., D.M.Sc., underscore the important role the brain’s waste disposal system may play in a range of neurological disorders. The new awards will advance understanding of how small vessel disease and traumatic brain injury can give rise to cognitive and behavioral problems.
Nedergaard and her colleagues first unveiled the brain’s unique method of removing waste – dubbed the glymphatic system – in a paper in Science Translational Medicine in 2012. The research revealed that the brain possesses a circulation network that piggybacks on blood vessels and uses cerebral spinal fluid to flush away waste products from brain tissue. Since that time, the team has gone on to show that the glymphatic system works primarily while we sleep, could be a key player in diseases like Alzheimer’s, and is disrupted after traumatic brain injury.Read More: New Grants Explore Role of Brain’s “Garbage Truck” in Mini-Stokes and Trauma
NGP Student Awarded NIH Fellowship

Nuclear Protein Causes Neuroblastoma to Become More Aggressive
Wednesday, September 28, 2016
Aggressive forms of neuroblastoma contain a specific protein in their cells’ nuclei that is not found in the nuclei of more benign forms of the cancer, and the discovery, made through research from the University of Rochester Medical Center (URMC), could lead to new forms of targeted therapy.
EYA1, a protein that contributes to ear development, is present in the cytoplasm of many neuroblastoma tumors, but this protein migrates to the nucleus in the cells of more aggressive forms of the disease. The research, recently published in two medical research journals, allows for the development of targeted drugs that will work to prevent the neuroblastoma from reaching this more aggressive stage; researchers at URMC and elsewhere have already begun testing some of these potential treatments in a laboratory setting.
“Neuroblastoma is one of the most common and deadly forms of childhood cancer, and this discovery allows us to identify drugs that prevent the change in EYA1 structure and potentially minimize the danger to a child who has this disease,” said Nina Schor, M.D., Ph.D., professor of Pediatrics and Neuroscience and the William H. Eilinger Chair of Pediatrics at URMC.

URMC Researchers Discover Rare Flu-Thwarting Mutation
Wednesday, September 28, 2016
A rare and improbable mutation in a protein encoded by an influenza virus renders the virus defenseless against the body’s immune system. This University of Rochester Medical Center discovery could provide a new strategy for live influenza vaccines in the future.
A new approach to the live flu vaccine would be particularly advantageous right now after the Centers for Disease Control and Prevention stopped recommending use of the live attenuate flu vaccine, FluMist® earlier this year. Several studies found that the pain-free nasal spray, which was used in about one-third of young children in the U.S., offered no protection to that especially vulnerable population. The flu shot, on the other hand, performed well and the CDC recommends using this vaccine in place of FluMist®.
“There is a need to understand what's happening with the existing live vaccine and potentially a need to develop a new one,” said David Topham, Ph.D., Marie Curran Wilson and Joseph Chamberlain Wilson Professor of Microbiology and Immunology at URMC and author of the study. “We proposed that the mutation we found could be used to create a live vaccine.”Read More: URMC Researchers Discover Rare Flu-Thwarting Mutation

Miller Receives Patent for Technology that Can Help Detect Flu
Thursday, September 15, 2016
Benjamin L. Miller, Ph.D., professor of Dermatology, recently received yet another patent for a new technology that can detect miniscule amounts of specific molecules in blood or other liquids. The patent focuses on using this technology to make detecting immune responses to the flu quicker and easier.
The AIR™ Platform, marketed by Adarza Biosystems, can detect immune responses to flu vaccines as well as the virus itself. With a small blood sample from a patient, doctors can confirm a flu infection, see if the patient mounts an appropriate immune response to a vaccine, or see if immune responses cross react with several different strains of flu. AIR™ can also be used for viral surveillance.
While Miller’s AIR™ system is not the first to make these things possible, it is a great improvement on previous technologies. Its silicon chip, which is only about the size of the end of a pencil eraser, allows scientists to detect hundreds of different target molecules in a single drop of fluid, and its “label-free” design requires fewer steps and reagents, thus reducing cost and opportunities for error.
“Label-free” systems suppress background noise to detect tiny signals, whereas conventional “labeled” systems use a more cumbersome design to amplify a tiny signal, often creating a lot of background noise in the process.
“It’s like walking through a city during the day and looking up at the buildings,” Miller said. “You have no idea what's going on in the offices because there's so much ambient light, but if you come back at night, it's easy to see.”
Miller suppresses background noise using a near-perfect anti-reflective coating on his silicon chips. For every 100 million photons of light that hit the surface of the chip, only one photon is reflected back. That coating also contains capture molecules meant to bind or “capture” specific target molecules, like antibodies produced in response to the flu virus. The more antibodies that bind to the chip, the more the anti-reflective coating is perturbed, and the more light is reflected and captured by a camera.
This simple and unconventional design and the ability to use capture molecules both big and small makes AIR™ extremely versatile. From cancer and infectious diseases, to agriculture and food safety, AIR™ is poised to expedite research and clinical testing across a wide range of applications.
Haber, Farrar Receive Awards
Tuesday, September 13, 2016
Suzanne N. Haber, Ph.D., has been awarded a NIH R13 Conference grant. On October 11-13, 2016, the University of Rochester Institute of Neuromedicine and the Silvio O. Conte Center will hold a meeting entitled “Persistent, maladaptive behaviors: why we make bad choices”. The program is designed to involve basic and clinical scientists with a specific focus on the fundamental elements that drive basic behaviors and action plans (reward, fear, and value assignment); circuit dysfunctions that underlie abnormalities in diseases with persistent, habit-like behaviors, despite some awareness that these behaviors are maladaptive; the circuit components that are common amongst diseases; computational approaches to understanding these circuits; and therapeutic approaches that effect these circuits.
Christopher Farrar, a Ph.D. candidate in the lab of Professor Denise Hocking, has been awarded a Ruth L. Kirschstein National Research Service Award (NIH-NRSA) Individual Predoctoral Fellowship (F31) from the National Heart, Lung, and Blood Institute for his project entitled “Influence of Extracellular Matrix Fibronectin on Platelet-Derived Growth Factor (PDGF) Signaling”. PDGF is produced by a variety of different cell types and stimulates mesenchymal cell proliferation, migration, and gene expression. Together with fibronectin, PDGF plays an important role in angiogenesis and wound repair. In contrast, excess PDGF and abnormal fibronectin matrix deposition are linked to several diseases, including pulmonary fibrosis, atherosclerosis, and certain cancers. The focus of Chris’ project is to determine how mesenchymal cell adhesion to extracellular matrix fibronectin fibrils influences the ability of these cells to respond to PDGF, with the long-term goal of developing new treatment approaches to effectively regulate the sensitivity of cells to growth factor stimulation.
Harris Gelbard Receives International Award for Neurovirology Research
Tuesday, September 13, 2016
Harris “Handy” Gelbard, M.D., Ph.D., director of the Center for Neural Development & Disease, is slated to receive the Hilary Koprowski Prize in Neurovirology at this year’s International Symposium on Molecular Medicine and Infectious Disease at Drexel University. Gelbard will be recognized for developing an unconventional drug that shows promise in treating brain disorders associated with HIV.
Gelbard’s drug, URMC-099, calms the immune system when it goes awry, as happens in HIV Associated Neurocognitive Disorder (HAND). In HAND, immune reactions to HIV particles in the brain damage nerve cells and cause dementia. Because patients affected by HAND also have HIV, it was imperative that URMC-099 not interfere with the antiretroviral drugs that keep HIV-positive patients alive.
KL2 award helps researcher pave his career path
Friday, September 9, 2016
David Auerbach, senior instructor in medicine,
says his KL2 award has "opened many doors for me."
David Auerbach's interest in pursuing a scientific career began during a hockey game his first year of college, when a teammate — who turned out to be a chief medical examiner — asked Auerbach if he would like to observe a case.
Now Auerbach's career is taking a major step forward with a two-year KL2 Mentored Career Development Program award from the University's Clinical and Translational Science Institute.
"It has opened up many doors for me," says Auerbach, including lead authorship of a recent paper in Neurology.
Auerbach, a senior instructor in the Department of Medicine/Aab Cardiovascular Research Institute, is taking a multisystem approach to understanding the mechanisms that cause electrical disturbances in both the hearts and brains of patients with genetic ion channel diseases. Ion channels, located in the plasma membrane of cells, are narrow tunnels that open and close at precise times to allow the flow of ions into or out of the cell, thus shaping the electrical activity in the heart and brain.
As a postdoc working with Lori Isom, a professor at the University of Michigan, Auerbach demonstrated that people with severe genetic forms of epilepsy were at a higher risk not only of electrical disturbances in the brain, resulting in seizures, but also of electrical disturbances in the heart, causing arrhythmias.
In order to establish an independent line of research, Auerbach decided to approach the problem in reverse: are people with long QT syndrome — a classically studied genetic cardiac disease that causes arrhythmias — also at an increased risk of seizures?
He came to Rochester in 2014 specifically because of its research strengths in this area, including the opportunity to work with such experts as Arthur Moss, the Bradford Berk Distinguished Professor of Medicine; Robert Dirksen, the Lewis Pratt Ross Professor and chair of pharmacology and physiology; and Charles Lowenstein, chief of cardiology and director of the Aab Cardiovascular Research Institute.Read More: KL2 award helps researcher pave his career path

DOD Grant Explores New Drugs to Thwart Impact of Trauma, Stroke, and Cardiac Arrest
Thursday, September 8, 2016
A $2.3 million Department of Defense grant will help neuroscientists develop new treatments for the emergency room and the battlefield. The research will focus on the development of new therapies that could help protect brain and other at risk organs following a trauma, heart attack, or stroke.
“While we have made significant progress in our ability to restore blood flow after stroke or cardiac arrest, the medical community does not have drugs at its disposal to prevent the secondary damage that occurs after these events,” said University of Rochester Medical Center neurologist Marc Halterman, M.D., Ph.D., the principal investigator of the study. “This grant will further our research on a promising class of drugs that possess both anti-inflammatory and cytoprotective properties that we believe will be suitable for use in both military and emergency conditions.”Read More: DOD Grant Explores New Drugs to Thwart Impact of Trauma, Stroke, and Cardiac Arrest

Automatic cortical representation of auditory pitch changes in Rett syndrome - John Foxe et al.
Thursday, September 1, 2016
Over the typical course of Rett syndrome, initial language and communication abilities deteriorate dramatically between the ages of 1 and 4 years, and a majority of these children go on to lose all oral communication abilities. It becomes extremely difficult for clinicians and caretakers to accurately assess the level of preserved auditory functioning in these children, an issue of obvious clinical import. Non-invasive electrophysiological techniques allow for the interrogation of auditory cortical processing without the need for overt behavioral responses. In particular, the mismatch negativity (MMN) component of the auditory evoked potential (AEP) provides an excellent and robust dependent measure of change detection and auditory sensory memory. Here, we asked whether females with Rett syndrome would produce the MMN to occasional changes in pitch in a regularly occurring stream of auditory tones.Read More: Automatic cortical representation of auditory pitch changes in Rett syndrome - John Foxe et al.

Pasternak Research Paper to be Published in J. Neuroscience
Thursday, August 4, 2016
The paper "Prefrontal Neurons Represent Motion Signals from Across
the Visual Field but for Memory-Guided Comparisons
Depend on Neurons Providing these Signals" will be published in J. Neuroscience shortly.
Visual decisions often involve comparisons of sequential visual motion that can appear at any location in the visual field. We
show that during such comparisons, the lateral prefrontal cortex (LPFC) contains accurate representation of visual motion
from across the visual field, supplied by motion processing neurons. However, at the time of comparison, LPFC neurons can
only use this information to compute the differences between the stimuli, if stimuli appear at the same retinal location,
implicating neurons with localized receptive fields in the comparison process. These findings show that sensory comparisons
rely on the interactions between LPFC and sensory neurons that not only supply sensory signals but also actively
participate in the comparison of these signals at the time of the decision.
Make sure to read the article when it comes out.

Luebke and Bennetto Explore Hearing Test That May Identify Autism Risk
Monday, July 25, 2016
Researchers have identified an inner ear deficiency in children with Autism that may impact their ability to recognize speech. The findings, which were published in the journal Autism Research, could ultimately be used as a way to identify children at risk for the disorder at an early age.
“This study identifies a simple, safe, and non-invasive method to screen young children for hearing deficits that are associated with Autism,” said Anne Luebke, Ph.D., an associate professor in the University of Rochester Medical Center Departments of Biomedical Engineering and Neuroscience and a co-author of the study. “This technique may provide clinicians a new window into the disorder and enable us to intervene earlier and help achieve optimal outcomes.”
“Auditory impairment has long been associated with developmental delay and other problems, such as language deficits,” said Loisa Bennetto, Ph.D., an associate professor in the University of Rochester Department of Clinical and Social Sciences in Psychology and a co-author of the study. “While there is no association between hearing problems and autism, difficulty in processing speech may contribute to some of the core symptoms of the disease. Early detection could help identify risk for ASD and enable clinicians to intervene earlier. Additionally, these findings can inform the development of approaches to correct auditory impairment with hearing aids or other devices that can improve the range of sounds the ear can process.”Read More: Luebke and Bennetto Explore Hearing Test That May Identify Autism Risk
McNair Summer Scholar Ashley Bui Talks Amygdala Circuits
Friday, July 22, 2016
Congratulations to Ashley Bui, a rising senior in Brain and Cognitive Sciences, on her presentation July 22, 2016. Her talk Projections from the Temporal Cortex to the Basal Nucleus of the Amygdala in the Macaque highlighted data from her summer project in our lab. The amygdala is required for computing which of the complex sensory stimuli that an individual encounters are emotionally meaningful, so that appropriate action can be taken. Ashley’s preliminary data shows that specific portions of the temporal cortex, which are critical for processing complex visual and auditory information, communicate with different regions of the amygdala. The results suggest that cortical areas that process complex visual information on 'what' and 'where' an object is (or is moving) are communicating with specific amygdala subregions. Thus, while determining the emotional importance of ‘what or who’ is important, biologic movements also likely influence amygdala activity and coding. We are happy that she will continue this work through the Fall semester.

Lisa A. DeLouise Receives Patent for Microfluidic Device
Friday, July 8, 2016
Lisa A. DeLouise, Ph.D., M.P.D., associate professor of Dermatology, Biomedical Engineering, Material Chemistry and Electrical and Computer Engineering and a member of the Environmental Health and Science Center, has received a patent for her microfluidic device and a method of manufacturing the device.
Research in the DeLouise Lab – funded by NYSTAR, NSF, DCFAR, CTSI and URVentures – has led to the development of a single cell screening technology platform based on microbubble well array. Single cell screening technologies can facilitate the discovery of rare cells.
DeLouise’s current work, in collaboration with James J. Kobie, Ph.D., assistant professor of Infectious Diseases, seeks to sort antigen-specific antibody-secreting B cells for the development of therapeutic monoclonal antibodies and the detection of cancer stem cells that harbor genetic mutations that confer their tumor-initiating and drug-resistant properties.
Meet Karl Smith, the Typewriting Tale Teller
Friday, July 8, 2016
The "Friends of Joe's Big Idea" is a vibrant community of talented people we think you should meet. With our feature, FOJBI Friday, we're introducing some of these cool communicators of science in their own words. This week: Karl Smith.
I'm a fifth-year biophysics doctoral candidate at the University of Rochester, where I study porous ultrathin silicon membranes. At the moment I'm taking a brief break from my research to be an American Academy for the Advancement of Science Mass Media Fellow at the Manhattan office of Scientific American.
Importance of science communication
I love science communication because it's both hard and important. People need to be told what scientists have discovered and what it means for their lives, but to do that well requires balancing the storytelling needs of journalism against objectivity and sober contextualization. Also, I personally find scientists to be generally fascinating people to write about and hear from.
Along with my co-producer Madeline Sofia, I created The Bench Warmer's Podcast, which tells stories of misadventures and victories in science using interviews with current and former graduate students. I think the stories that don't often get told about science — the scoops, the failures, the dead ends, rewrites and rejections — are just as important to tell as the wild success stories. Not only that, but I think we short-sell our successes by not highlighting how rare they are. So, in the podcast, Maddie and I ask questions like "What's the most expensive thing you ever broke in lab?" and "Have you ever embarrassed yourself by dislocating your knee while singing karaoke onstage in front of hundreds of your scientific peers and possible future employers?"
I also write "10-cent stories" for children at the Rochester Museum and Science Center and at a few other places around Rochester. The children give me a prompt and in five minutes I use my typewriter to type them a tale. I've been doing this for about three years now, and I've written well over 800 stories. Sometimes the stories have a STEM bend to them, but sometimes they're just stories. I love this project for a lot of reasons, but most of all because it lets me make the world a stranger, more whimsical place.
I've only been at my fellowship for a few weeks, so I'm still deciding if I want to be a science journalist or if my plans lie elsewhere. This is a time of great flux for me, so I don't know yet where I'm heading. But I'm enjoying figuring it out.Read More: Meet Karl Smith, the Typewriting Tale Teller

David Yule appointed Louis C. Lasagna Professor
Tuesday, July 5, 2016
David Yule, professor of pharmacology and physiology, has been appointed the Louis C. Lasagna Professor in Experimental Therapeutics for five years, effective July 1. He retains his joint appointments as professor of medicine and as professor in the Center for Oral Biology.
For the past 15 years, Yule has studied calcium’s role in disorders in which calcium signaling and secretions are disrupted, such as Sjögren’s syndrome—in which patients experience dry mouth due to a lack of saliva—and acute pancreatitis.
Using state-of-the art imaging and electrophysiological techniques, Yule’s lab monitors calcium signals to achieve a better understanding of the mechanisms that underlie these signals with the goal that the studies will give insight into the control of important physiological processes in both normal physiology and disease states.
Yule received his PhD in physiology from the University of Liverpool in the United Kingdom. His research has been published in numerous journals, including the Journal of Biological Chemistry, Proceedings of the National Academy of Sciences, Science Signaling, and the Journal of Physiology. Yule serves on the editorial board for Gastroenterology, the preeminent journal in the field of gastrointestinal disease.
The Lasagna professorship honors Louis Lasagna, who served as chair of the Department for Pharmacology from 1970 to 1983, and brought the department to national recognition as a center of training and research. Lasagna, who was known for pioneering the study of placebos and writing an alternative Hippocratic oath, died in 2003.

URMC Team Revises Understanding of Genetic Code
Friday, July 1, 2016
Beth Grayhack, Ph.D., with lab
members and grad students
Christina Brule and Jiyu Wang
Scientists for years have known that the genetic code found in all living things contains many layers of complexity. But new research from the University of Rochester cracks the code more deeply, clarifying for example why some genes are inefficiently translated into proteins.
In a study published in the journal Cell, the researchers, co-led by Beth Grayhack, Ph.D., of the UR School of Medicine and Dentistry, discovered the existence and identity of 17 pairs of inefficient codons (DNA nucleotides or bases) within the genetic code.
Scientists have generally considered each piece of the genetic code (or codon) as a single “word” in a language. But the new data suggests some codon combinations act as compound words or phrases whose order and pairing has a significant impact on the translation of genes into proteins.
“Consider the words ‘pancake’ versus ‘cake pan,’ “ said Grayhack, an associate professor of Biochemistry and Biophysics, Pediatrics, and Cancer, in the Center for RNA Biology, at the UR Medical Center.Read More: URMC Team Revises Understanding of Genetic Code
The Sleep Hack Neuroscience Says Gives Your Brain Optimal Rest
Thursday, June 30, 2016
Sleep is critical for rest and rejuvenation. A human being will actually die of sleep deprivation before starvation--it takes about two weeks to starve, but only 10 days to die if you go without sleep.
The CDC has also classified insufficient sleep as a public health concern. Those who don't get enough sleep are more likely to suffer from chronic diseases that include hypertension, diabetes, depression, obesity, and cancer.
It's thus vital to get enough shuteye, but it turns out your sleep position also has a significant impact on the quality of rest you get.
Now, a neuroscience study suggests that of all sleep positions, one is most helpful when it comes to efficiently cleaning out waste from the brain: sleeping on your side.
The study, published in the Journal of Neuroscience, used dynamic contrast-enhanced MRI to image the brain's "glymphatic pathway." This is the system by which cerebrospinal fluid filters through the brain and swaps with interstitial fluid (the fluid around all other cells in the body).
"It is interesting that the lateral [side] sleep position is already the most popular in humans and most animals--even in the wild," said University of Rochester's Maiken Nedergaard. "It appears that we have adapted the lateral sleep position to most efficiently clear our brain of the metabolic waste products that build up while we are awake."Read More: The Sleep Hack Neuroscience Says Gives Your Brain Optimal Rest

Review: Giving Gene Editing Technology CRISPR-Cas9 a Boost
Thursday, June 23, 2016
A new gene editing technology called CRISPR-Cas9 has taken the scientific world by storm. It allows researchers to quickly and easily make changes to the DNA of humans, animals and plants. The hope is that CRISPR-Cas9 may be used in the future to eliminate or correct faulty genes that cause disease.
In a recent issue of the journal Cell, Lynne E. Maquat, Ph.D. and Maximilian W. Popp, Ph.D. of the University of Rochester Center for RNA Biology describe how scientists can make this technology more efficient. Understanding the principles of nonsense-mediated mRNA decay (NMD), a cellular mechanism that Maquat discovered early in her career, will help anyone employing the technology achieve a better result – namely, a more complete knock out or deletion of a desired gene.

Swapping Sick for Healthy Brain Cells Slows Huntington’s Disease
Tuesday, June 7, 2016
Researchers have successfully reduced the symptoms and slowed the progression of Huntington’s disease in mice using healthy human brain cells. The findings, which were published today in the journal Nature Communications, could ultimately point to a new method to treat the disease.
The research entailed implanting the animals with human glia cells derived from stem cells. One of the roles of glia, an important support cell found in the brain, is to tend to the health of neurons and the study’s findings show that replacing sick mouse glia with healthy human cells blunted the progress of the disease and rescued nerve cells at risk of death.
“The role that glia cells play in the progression of Huntington’s disease has never really been explored,” said Steve Goldman, M.D., Ph.D., co-director of the University of Rochester Center for Translational Neuromedicine. “This study shows that these cells are not only important actors in the disease, but may also hold the key to new treatment strategies.” Read More: Swapping Sick for Healthy Brain Cells Slows Huntington’s Disease
Harold Smith Publishes Commentary on RNA and DNA Editing
Sunday, June 5, 2016
Epigenetics is a popular, yet still mysterious concept in health and medicine. It’s the study of a variety of biological processes that alter the expression of our genes. Sometimes this involves modifying the structure of our chromosomes to mask or unmask genes, and other times the actual genetic code is changed in certain cells. Harold C. Smith, Ph.D., a longtime professor of Biochemistry and Biophysics at the University of Rochester School of Medicine and Dentistry has studied epigenetics in a research focus known as RNA and DNA editing since it was introduced two decades ago. He was invited to write a commentary on the progress and future of this research, published today in Trends in Biochemical Sciences, and answers a few questions about the subject.Read More: Harold Smith Publishes Commentary on RNA and DNA Editing

GDSC Graduate Nirmalya Chatterjee reports a novel role of Bet proteins in the control of the oxidative stress response pathway.
Friday, May 27, 2016
Bet proteins are a subclass of bromodomain containing epigenetic “readers”. These proteins have complex and incompletely understood functions in the control of gene expression and chromatin organization. The human Bet proteins Brd3 and Brd4 have been implicated in cancer and thanks to the availability of specific inhibitors, have emerged as promising drug targets. The paper by Nirmalya Chatterjee, Min Tian and others describes experiments in Drosophila that discovered a novel function for Bet proteins: the regulation of the transcription factor Nrf2. The reported data show that a Drosophila Bet protein is part of a previously unknown pathway that can control Nrf2 activity. This is of interest as Nrf2 plays a prominent role in the defense against oxidative stress, protection against various diseases, and aging. Nirmalya Chatterjee, a recent member of the Bohmann Lab, received the PhD last September and is currently working as a postdoc in the group of Norbert Perrimon at Harvard Medical School.
Nirmalya Chatterjee2, Min Tian3, M., Kerstin Spirohn, Michael Boutros & Dirk Bohmann (2016) Keap1-Independent Regulation of Nrf2 Activity by Protein Acetylation and a BET Bromodomain Protein, PLoS Genetics, will go to press 5/27/2016. PMID: 27233051

GDSC Student Xuan Li publishes on the role of Cdk12 in response to stress.
Monday, May 23, 2016
The phosphorylation of RNA polymerase II in the C-terminal domain, or CTD, is an essential step for the transcription of all eukaryotic protein coding genes. The paper be Xuan Li and colleagues describes the unexpected discovery that a certain CTD kinase, called CDK12, is not universally required, but is only needed for the transcription of genes that are inducible by stress, such as heat, DNA damage or reactive oxygen species. This finding suggests that CTD phosphorylation plays a role in the regulation of specific gene expression programs, rather than being a generic step of transcription. This work involved a large-scale robotic RNAi screen in collaboration with the Boutros lab in Heidelberg, as well as genetic and biochemical experiments in the Drosophila model system. Xuan Li, a graduate student in the Bohmann Lab is currently doing an internship at Takeda Pharmaceuticals in Boston and will defend her PhD in November.

Conventional Radiation Therapy May Not Protect Healthy Brain Cells
Wednesday, May 18, 2016
A new study shows that repeated radiation therapy used to target tumors in the brain may not be as safe to healthy brain cells as previously assumed. The findings, which appear in the International Journal of Radiation Oncology, Biology, Physics, show that the treatment also kills important support cells in the brain and may cause as much, if not more damage, than single dose radiation therapy.
“This study suggests that conventional repeated radiation treatments offer no significant benefit to brain tumor patients,” said Kerry O’Banion, M.D., Ph.D., a professor in the University of Rochester Medical Center (URMC) Department of Neuroscience and lead author of the study. “It also shows that certain cell populations in the brain are vulnerable to radiation and this may help explain why so many brain cancer patients experience cognitive problems after treatment.” Read More: Conventional Radiation Therapy May Not Protect Healthy Brain Cells

28th Annual Genetics Day Meeting
Wednesday, May 11, 2016
Dr. Michael Levine
This year's Genetics Day provided another opportunity to celebrate the impact of Genetics on science and medicine. An excellent selection of speakers from the University of Rochester Medical Center highlighted the importance of diverse genetic mechanisms ranging from chromatin remodeling in erythropoesis (Laurie Steiner) and DNA damage repair (Xi Bin) to translational control by riboswitches (Joe Wedekind) and di-codon usage (Elizbeth Grayhack). Genetics Day concluded with the Fred Sherman lecture by Dr. Michael Levine (Princeton University). His presentation on visualizing the mechanisms of transcriptional enhancers was equally entertaining and insightful. Originally from the Hollywood area, and by his own admission a closet movie producer, Dr. Levine wowed audiences with in vivo movies of enhancer reporters, shedding new light on what we all thought was an established principle of molecular genetics.

When the Physical World is Unreliable: Study Finds Visual and Tactile Processing Deficits in Schizophrenia
Tuesday, May 10, 2016
A new study out today in the journal Translational Psychiatry sheds further light on the idea that schizophrenia is a sensory disorder and that individuals with the condition are impaired in their ability to process stimuli from the outside world. The findings may also point to a new way to identify the disease at an early stage and before symptoms become acute.
Because one of the hallmarks of the disease is auditory hallucinations, such as hearing voices, researchers have long suspected a link between auditory processing and schizophrenia. The new study provides evidence that the filtering of incoming visual information, and also of simple touch inputs, is also severely compromised in individuals with the condition.
“When we think about schizophrenia, the first things that come to mind are the paranoia, the delusions, the disorganized thinking,” said John Foxe, Ph.D., the chair of the University of Rochester Medical Center Department of Neuroscience and senior author of the study. “But there is increasing evidence that there is something fundamentally wrong with the way these patients hear, the way they feel things through their sense of touch, and in the way in which they see the environment.”Read More: When the Physical World is Unreliable: Study Finds Visual and Tactile Processing Deficits in Schizophrenia

Subtle Chemical Changes in Brain Can Alter Sleep-Wake Cycle
Friday, April 29, 2016
A study out today in the journal Science sheds new light on the biological mechanisms that control the sleep-wake cycle. Specifically, it shows that a simple shift in the balance of chemicals found in the fluid that bathes and surrounds brain cells can alter the state of consciousness of animals.
The study, which focuses on a collection of ions that reside in the cerebral spinal fluid (CSF), found that not only do these changes play a key role in stimulating or dampening the activity of nerve cells, but they also appear to alter cell volume causing brain cells to shrink while we sleep, a process that facilitates the removal of waste.
“Understanding what drives arousal is essential to deciphering consciousness and the lack thereof during sleep,” said Maiken Nedergaard, M.D., D.M.Sc., co-director of the University of Rochester Center for Translational Neuromedicine and lead author of the study. “We found that the transition from wakefulness to sleep is accompanied by a marked and sustained change in the concentration of key extracellular ions and the volume of the extracellular space.”
The current scientific consensus is that the brain is “woken up” by a set of neurotransmitters – which include compounds such as acetylcholine, hypocretin, histamine, serotonin, noradrenaline, and dopamine – that originate from structures deep within the brain and the brain stem. This cocktail of chemical messengers serve to activate – or arouse – a set of neurons in the cerebral cortex and other parts of the brain responsible for memory, thinking, and learning, placing the brain in a state of wakefulness.Read More: Subtle Chemical Changes in Brain Can Alter Sleep-Wake Cycle

Harold Smith Inducted into Royal Society of Biology
Friday, April 8, 2016
Dr. Harold Smith, Professor of Biochemistry & Biophysics has been inducted into the Royal Society of Biology.
A long time member of the department, Dr. Smith's primary interest is understanding the composition, regulation and structure of macromolecular complexes involved in regulating gene expression at the level of messenger RNA expression and processing. The lab's focus is on a platform of enzymes that change the genetic code at the DNA or RNA level by deaminating cytidine to form uridine. Current data suggest that this family of cytidine deaminase function with other proteins (auxiliary proteins) as holoenzymes complexes which we refer to as editosomes (for RNA) or mutasomes (for DNA). RNA editing or DNA mutational activity by these enzymes affect the protein coding capacity of mRNAs and thereby can diversify the proteins that are expressed by cells (the proteome). Please visit the Smith Lab for more information. Dr. Smith has a 30 year track record of teaching and mentoring graduate students, medical students and undergraduates at the University of Rochester and has lead curriculum design and reform for these programs.
The Royal Society of Biology (RSB), previously called the Society of Biology, is a learned society in the United Kingdom created to advance the interests of biology in academia, industry, education, and research. Formed in 2009 by the merger of the Biosciences Federation and the Institute of Biology, the society has around 16,000 individual members, and over 100 member organizations. In addition to engaging the public on matters related to the life sciences, the society seeks to develop the profession and to guide the development of related policies.

Researchers have developed a new and highly efficient method for gene transfer. The technique, which involves culturing and transfecting cells with genetic material on an array of carbon nanotubes, appears to overcome the limitations of other gene editing technologies.
The device, which is described in a study published today in the journal Small, is the product of a collaboration between researchers at the University of Rochester Medical Center (URMC) and the Rochester Institute of Technology (RIT).
“This platform holds the potential to make the gene transfer process more robust and decrease toxic effects, while increasing amount and diversity of genetic cargo we can deliver into cells,” said Ian Dickerson, Ph.D., an associate professor in the Department of Neuroscience at the URMC and co-author of the paper.Read More: “Honeycomb” of Nanotubes Could Boost Genetic Engineering
Study: The Science behind Bodily Secretions
Tuesday, April 5, 2016
The salivary gland secretes saliva that helps us chew and swallow the food we eat. The pancreas secretes digestive juices that enable our bodies to break down the fat, protein, and carbohydrates in the food. Secretions like these are important in countless activities that keep our bodies running day and night. A study published today in the journal Science Signaling uncovers a previously mysterious process that makes these secretions possible.
At the heart of the new study is calcium, which is present in all of our cells and is a gatekeeper of sorts: an increase in calcium in our cells opens up “gates” or “channels” that are required for the production and secretion of fluids like saliva. If calcium doesn’t increase inside cells the gates won’t open, a problem that occurs in diseases like Sjögren’s syndrome. Sjögren’s patients experience dry mouth due to a lack of saliva and have difficulty chewing, swallowing, and speaking, which severely hampers quality of life.
For the past 15 years David I. Yule, Ph.D., professor in the department of Pharmacology and Physiology at the University of Rochester School of Medicine and Dentistry has studied calcium’s role in Sjögren’s and other disorders in which calcium and secretions are disrupted, like acute pancreatitis. In the new study he answers an important question that has stumped scientists for years: what does it take for a particularly important calcium channel to open and start these processes?Read More: Study: The Science behind Bodily Secretions

Early Wiring of Brain's “Fear” Centers Could Produce Long-term Consequences
Monday, March 21, 2016
New research shows that our brains may be hardwired to become sensitive to stressful environments at an early age and, if overstimulated, this may contribute to anxiety disorders and even psychotic syndromes later in life.
The study, which appears in the journal Brain Structure and Function, focuses on two structures deep in the brain. The central nucleus of the amygdala (Ce) is thought to be involved in responses to immediate threats and stimulus, such as becoming startled or freezing in reaction to a loud noise. The bed nucleus of the stria terminalis (BST) is thought to be involved in regulating a person’s state of vigilance, such as determining whether or not an environment or a situation poses a potential threat. Animal and human studies show that when the BST is activated by a threatening situation, we tend to slow down, become quieter, and stress hormones spike.
While Ce and BST reside in different parts of the brain, the two areas are hardwired to each other by axonal tracts – basically, bundles of long distance axon fibers that enable the separate regions to communicate with each other. However, until now it has not been clear when these connections form or the way in which they interact with each other.
In the study published today, a team of researchers led by Julie Fudge, M.D., with the Department of Neuroscience observed that these connections are made at a very early stage of development in non-human primates. They also found that the direction of the connection is essentially a one way street. The Ce – or immediate fear signaling center – conveys information to the BST, the structure that mediates general threat sensing or anxiety states. This arrangement suggests that repeated activation of the Ce by immediately fearful or traumatic events may shape long-term anxiety states in the BST.Read More: Early Wiring of Brain's “Fear” Centers Could Produce Long-term Consequences
Omega 3 Fatty Acids May Reduce Bacterial Lung Infections Associated with COPD
Tuesday, March 15, 2016
Compounds derived from omega-3 fatty acids – like those found in salmon – might be the key to helping the body combat lung infections, according to researchers at the University of Rochester School of Medicine and Dentistry.
The omega-3 derivatives were effective at clearing a type of bacteria called Nontypeable Haemophilus influenzae (NTHi), which often plagues people with inflammatory diseases like chronic obstructive pulmonary disease (COPD).
COPD, which is most often caused by years of smoking, is characterized by inflammation and excessive mucus in the lungs that blocks airflow. Quitting can slow the progress of COPD, but it doesn’t halt the disease. Anti-inflammatory drugs are the most common treatment, however they suppress the immune system, which can put people with COPD at risk for secondary infections, most commonly NTHi bacterial infections.
“Our biggest concern with patients who have COPD is bacterial infections, which often put their lives at risk,” says Richard Phipps, Ph.D. professor of Environmental Medicine and director of the URSMD Lung Biology and Disease Program. “If we can figure out how to predict who is likely to get an infection, physicians could put them on a preventative medication.”
In his recent study, which was featured in the top ten percent of the March 15 issue of The Journal of Immunology, Phipps and lead author, Amanda Croasdell, a graduate student in the Toxicology program, tested the effectiveness of an inhalable omega-3 derivative to prevent NTHi lung infections in mice.Read More: Omega 3 Fatty Acids May Reduce Bacterial Lung Infections Associated with COPD
The Brain’s Gardeners: Immune Cells ‘Prune’ Connections Between Neurons
Monday, March 7, 2016
Microglia (green) with purple representing the P2Y12 receptor which the study shows is a critical regulator in the process of pruning connections between nerve cells.
A new study out today in the journal Nature Communications shows that cells normally associated with protecting the brain from infection and injury also play an important role in rewiring the connections between nerve cells. While this discovery sheds new light on the mechanics of neuroplasticity, it could also help explain diseases like autism spectrum disorders, schizophrenia, and dementia, which may arise when this process breaks down and connections between brain cells are not formed or removed correctly.
“We have long considered the reorganization of the brain’s network of connections as solely the domain of neurons,” said Ania Majewska, Ph.D., an associate professor in the Department of Neuroscience at the University of Rochester Medical Center (URMC) and senior author of the study. “These findings show that a precisely choreographed interaction between multiple cells types is necessary to carry out the formation and destruction of connections that allow proper signaling in the brain.”
The study is another example of a dramatic shift in scientists’ understanding of the role that the immune system, specifically cells called microglia, plays in maintaining brain function. Microglia have been long understood to be the sentinels of the central nervous system, patrolling the brain and spinal cord and springing into action to stamp out infections or gobble up dead cell tissue. However, scientists are now beginning to appreciate that, in addition to serving as the brain’s first line of defense, these cells also have a nurturing side, particularly as it relates to the connections between neurons.Read More: The Brain’s Gardeners: Immune Cells ‘Prune’ Connections Between Neurons
The Future of Photonics
Tuesday, February 23, 2016
As hundreds of millions of dollar pour into Rochester to establish the nation's first Photonics Hub, Mark Gruba has a closer look at the technology in a News 8 special report, "The Future of Photonics."
Photonics is the science and technology of generating, controlling and detecting photons, which are particles of light. A display at the Rochester Museum & Science Center houses examples of its many applications. In one, a transmitter converts an audio signal from electrical pulses into light pulses. The laser beam sends that information to the receiver, which converts the light pulses back to electrical pulses and sends them to the speaker for your listening enjoyment.
"We work on optical bio sensors," said Dr. Ben Miller, a researcher at the University of Rochester Medical Center. He's creating a sensor that can detect the presence of hundreds of viruses from a single blood sample, in real time. "We're working to make devices so that you can immediately get that information in the doctor's office," said Dr. Miller.Read More: The Future of Photonics
Hope, Hype, and Wishful Thinking
Monday, February 22, 2016
In a perspective piece appearing in the journal Cell Stem Cell, URMC neurologist Steve Goldman, M.D., Ph.D., lays out the current state of affairs with respect to stem cell medicine and how close we are to new therapies for neurological disorders.
The dawn of stem cell medicine some 25 years ago was greeted with great enthusiasm, particularly by scientists who study diseases in the central nervous system (CNS). Many of the diseases found in the brain and spinal cord are degenerative in nature; meaning that over time populations of cells are lost due to genetic factors, infection, or injury. Because stem cell medicine holds the potential to repair or replace damaged or destroyed cells, scientists have considered these diseases as promising candidates for new therapies.
However, as with other emerging fields of medicine, the race to cures has turned out to be more of marathon than a sprint. While scientists have become very adept at manipulating stem and progenitor cells and understanding the complex choreography of genetic and chemical signals that instruct these cells to divide, differentiate, and proliferate, researchers are still grappling with the challenges of how to integrate new cells into the complex network of connections that comprise the human brain.
Goldman, co-director of the URMC Center for Translational Neuromedicine, takes a sweeping view of where we stand and which CNS diseases may or may not ultimately benefit from future stem cell-based therapies.Read More: Hope, Hype, and Wishful Thinking

Richard Aslin's Rochester Baby Lab Shows
Wednesday, February 17, 2016
Amelia Smith sits on the floor of a newly remodeled wing of the University of Rochester's department of Brain and Cognitive Sciences. The 8-month old wears a headband of cottony roses, and tiny bubbles form in the corner of her mouth. She's completely entranced by the commotion around her.
Though few adults in the room can resist oohing and aww-ing, little Amelia is not there to be fawned over. She's there to work. Researchers at the UR's Baby Lab want to know what she's thinking, what she's learned so far in her young life, and how she learned it.
But there's a problem: Amelia can't talk yet.
The work being investigated in Richard Aslin's Baby Lab was written up in the City Newspaper article "Signs of Intelligent Life".Read More: Richard Aslin's Rochester Baby Lab Shows
Tracking Melanoma Metastasis Leads to Key Gene Discovery
Wednesday, February 17, 2016
A Wilmot Cancer Institute investigator discovered a gene that’s required for the initiation of melanoma and the growth of disseminated melanoma cancer cells in the lungs.
The findings suggest that the gene’s signaling pathway may be proof that melanoma stem cells exist, a question that’s being debated by scientists.
Lei Xu, Ph.D., associate professor of Biomedical Genetics at the University of Rochester Medical Center, is lead author of the study, which was recently published in PLOS ONE and funded by a Wilmot Cancer Institute pilot grant. The Xu lab investigates the multiple, complex steps that occur as cancer cells spread from the original tumor to other parts of the body.

Report Recommends More Treatment, Research, for Gulf War Vets
Monday, February 15, 2016
The cause of Gulf War illness is still a mystery but focusing on treatments and interventions might help the veterans of Operation Desert Storm as well as the troops of the future, according to an Institute of Medicine committee report led by University of Rochester Medical Center Professor Deborah Cory-Slechta.
In 1990 and ’91 nearly 700,000 U.S. troops deployed to the Persian Gulf region for a short, intense war. Few injuries or deaths occurred, but troops were exposed to chemical and biological weapons, vaccines, oil-fires, air pollution, bomb blasts, pesticides, extreme desert temperatures, and constant false alarms and fear of nerve-gas attacks.
After the war ended a high number of the veterans reported debilitating fatigue, muscle and joint pain, headaches, and cognitive problems. This became known as “Gulf War illness.” During the past 25 years, 10 different committees of the nation’s top medical experts have searched for evidence that would better define Gulf War illness and possible treatments. The latest committee, headed by Cory-Slechta, concluded that no single mechanism can explain the multitude of symptoms seen in Gulf War illness—and that it’s unlikely a cause will ever be identified.Read More: Report Recommends More Treatment, Research, for Gulf War Vets
Doing something larger than you could ever do on your own
Friday, February 12, 2016
"There is a tendency for many investigators, especially early in their careers, to hold onto their work and not share it," says David Williams, the William G. Allyn Professor of Medical Optics; Dean for Research in Arts, Sciences and Engineering; Director of the Center for Visual Science - and a leading eye expert who pioneered the use of adaptive optics for vision correction.
"They don't realize - and it's one of the things that took me longer to learn than I wish it had - that one of the best ways to build your reputation is to share your ideas or your technology with the hope that they will be adopted.
"I was lucky enough to realize that if I let my students take my adaptive optics technology and use it to build their own labs, for example, it not only helped them get their independent research programs off the mark but also enhanced my reputation because so many more people were able to access and deploy the technology."
Is it any wonder then, that of the five NEI Audacious Goals grants recently awarded to Williams and four other investigators:
- four of the projects use adaptive optics as their core technology?
- three of the other PI's are either current collaborators with Williams or former postdocs in his lab?
- which means that four of the PI's will be cooperating with each other, even as they individually collaborate with other experts in the field on their individual projects - in effect widening the opportunities for synergy?
"That's the excitement of this," Williams says. "Why should we compete when one group can do one piece of it, and a second group can do another, and as along as you can manage authorships and credit appropriately and fairly, we can be much more efficient and effective in getting things done?"
"One of the things I'm proudest about in this community of people around the world doing adaptive optics and retinal imaging is that almost all of us get along really well, and we're moving science forward as rapidly as we can by helping each other. That doesn't always happen in science."
As Dean of Research for Arts, Science and Engineering, Williams is always looking for young faculty throughout AS&E who have the right personality and vision to take on larger, multi-investigator, multi-institutional projects.
"You have to be gregarious and interested in working with other people and tolerating the quirks that they have, just as they have to tolerate the quirks you have," Williams said.
"The largest source of optimism for me about the AS&E research portfolio is the quality of our junior faculty members - their enthusiasm and energy. Many of them have cut their teeth on individual investigator awards and will reach a certain point in mid career when they realize they need to reach out for complementary expertise in order to do more."
Williams' advice: The best collaborator may not be the first one that comes to mind.
"One of the biggest mistakes faculty members make is to choose a collaborator who is just like them, who has the same interests in a problem and the same background and who they can easily begin a conversation with because they are so closely aligned. But that doesn't really help your research. You want to have somebody who . . . has a completely different skills set. As obvious as that is, it doesn't always get factored into planning how to accumulate the necessary wisdom to do something larger than you could ever do on your own."
Scientists Seek to Improve Flu Vaccine for the Very Young

Scientists at the University of Rochester School of Medicine and Dentistry have discovered a way to make a nasal spray flu vaccine safer for those who are at greatest risk of catching the flu, particularly infants under the age of 2. The work is early and a long way from being applied in people, but offers promise for a vaccine that could better protect the most vulnerable.Read More: Scientists Seek to Improve Flu Vaccine for the Very Young
Study Sheds Light on Source of Drug Addicts' Risk-Taking Behavior
Wednesday, February 10, 2016
A study out today provides new insight into how the brains of drug addicts may be wired differently. The findings, which appear in the journal Psychopharmacology, show that while drug users have very strong motivation to seek out "rewards," they exhibit an impaired ability to adjust their behavior and are less fulfilled once they have achieved what they desire. Addressing this disconnect between the craving for a drug and the ability to regulate behavior may be one of the keys to breaking the cycle of addiction.
"The vast majority of people, when faced with something they want, will assess how achievable the goal is and adjust their actions and expectations in order to maximize their potential to achieve it," said John Foxe, PhD, the chair of the Department of Neuroscience at the University of Rochester Medical Center and senior author of the study. "However, it appears that the integrity of this system of assessment and self-regulation is impaired in substance abusers and this may contribute to the risk-taking behaviors and poor decision-making commonly associated with this population."Read More: Study Sheds Light on Source of Drug Addicts' Risk-Taking Behavior
Lead poisoning still an issue in Rochester
Tuesday, February 9, 2016
The Michigan city of Flint became ground zero of the nation's latest public-health outrage when it was learned in recent months that its tap water contained unsafe levels of toxic lead.
Though the aqueous cause of its lead problem is unusual, Flint is otherwise far from unique. Many American cities, including Rochester, continue to struggle with lead poisoning, particularly of children.
In fact, despite years of successful anti-lead work locally, the proportion of children in Rochester found to have elevated levels of lead in their blood still was roughly double that of their counterparts in Flint in 2014, the most recent year for which comparable data are available.
Read More: Lead poisoning still an issue in Rochester
We have had a huge amount of progress here. We’ve had a nearly 90 percent reduction in the number of kids with elevated blood lead levels in the past 15 years, said Katrina Smith Korfmacher, an associate professor of environmental medicine at the University of Rochester Medical Center who has long been involved in local anti-lead efforts.
But I would say it’s still a serious, or an ongoing, problem. The point is, it won’t ever go away entirely, because there is lead in the environment.
Scientists Discover Stem Cells Capable of Repairing Skull, Face Bones
Monday, February 1, 2016
The photo shows a blue-stained stem cell and a red-stained stem cell that each generated new bones cells after transplantation.
A team of Rochester scientists has, for the first time, identified and isolated a stem cell population capable of skull formation and craniofacial bone repair in mice—achieving an important step toward using stem cells for bone reconstruction of the face and head in the future, according to a new paper in Nature Communications.
Senior author Wei Hsu, Ph.D., dean’s professor of Biomedical Genetics and a scientist at the Eastman Institute for Oral Health at theUniversity of Rochester Medical Center, said the goal is to better understand and find stem-cell therapy for a condition known as craniosynostosis, a skull deformity in infants. Craniosynostosis often leads to developmental delays and life-threatening elevated pressure in the brain.
Hsu believes his findings contribute to an emerging field involving tissue engineering that uses stem cells and other materials to invent superior ways to replace damaged craniofacial bones in humans due to congenital disease, trauma, or cancer surgery.
For years Hsu’s lab, including the study’s lead author, Takamitsu Maruyama, Ph.D., focused on the function of the Axin2 gene and a mutation that causes craniosynostosis in mice. Because of a unique expression pattern of the Axin2 gene in the skull, the lab then began investigating the activity of Axin2-expressing cells and their role in bone formation, repair and regeneration. Their latest evidence shows that stem cells central to skull formation are contained within Axin2 cell populations, comprising about 1 percent—and that the lab tests used to uncover the skeletal stem cells might also be useful to find bone diseases caused by stem cell abnormalities.
The team also confirmed that this population of stem cells is unique to bones of the head, and that separate and distinct stem cells are responsible for formation of long bones in the legs and other parts of the body, for example.
The National Institutes of Health and NYSTEM funded the research.

Strong Star Certificate of Appreciation Awarded to Dr. Jermaine “JJ" Jenkins
Tuesday, January 26, 2016
On January 22, 2016, Dr. Jermaine Jenkins, who runs the Structural Biology and Biophysics Facility, was nominated for going 'above and beyond' in his work for a client of the facility. The client commented in their nomination:
The clinical trials group had a very tight timeline to meet for one of our clients. Testing had to be completed by the 25th of January so the client could present the data to the FDA. JJ was aware of the required quick turnaround time and he met the challenge. He worked the weekend so that our client's needs would be met. It is so impressive to work with such a dedicated scientist who takes his job so seriously. With JJ's help, URMC Labs Clinical Trials group made a very good impression on a client.
As Facility Manager of the Structural Biology and Biophysics Facility, Dr. Jenkins offers support services to determine macromolecular x-ray crystal structures, and to investigate protein-protein, protein-nucleic acid or protein-small molecule interactions. Professor Clara Kielkopf – a long time user and co-founder of the Facility commented,
JJ quickly, calmly and reliably responds to user needs. Co-director of the Facility Professor Joseph Wedekind added,

CTSI Trainee Pilot supports better understanding of lupus
Friday, January 15, 2016
Lupus is a devastating disease that affects around 1 in 2,000 people in the U.S., and involves chronic inflammation and tissue damage in various organs including the skin, kidneys, and joints. Although the mortality rate for lupus has improved in recent decades, a diagnosis of lupus often means elevated risk of early mortality and lifetime of immunosuppressive therapy, which can carry significant side effects.Read More: CTSI Trainee Pilot supports better understanding of lupus
The Scientist as Storyteller

at the WRUR studios in Todd Union. (Photo: Adam Fenster)
For Karl Smith, the storytelling bug began with a Montgomery Ward No. 22 typewriter purchased for $5 at a moving sale.
Typewriter perched on his lap, the doctoral student in biophysics has become a fixture at the Rochester Public Market, Corn Hill Arts Festival, and other Rochester-area arts-oriented venues. For 10 cents, he crafts a half-sheet-long tale about grandchildren, lost loves, pets, or the absurd. The clacking of keys on paper draws a curious crowd.
I derive a lot of meaning and joy from making things that other people draw joy from, says Smith.
As a graduate student at Rochester, Smith has been finding lots of ways to share his love of storytelling. In addition to his peripatetic typewriting, he’s the leader of Rocket Radio Theater, a troupe of radio performers whose core membership includes fellow like-minded medical science graduate students Clarence Ling, Jon Baker, Carolyn Klocke, Bronwyn Lucas, and Matt Payea.
The project began in 2013 with a recording at Smith’s kitchen table. The group, which now records in the studios of campus radio station WRUR, hosts several serial drama podcasts and stand-alone stories created by Smith. Its feature series, The Bootleggers, takes place during prohibition-era Rochester, playing up aspects of local history and landscapes.
In his research as a biophysicist, Smith explores nanoporous silicon membranes in the lab of James McGrath, professor of biomedical engineering. Smith describes the membranes as
coffee filters made of glass that are 10,000 times thinner than a human hair.
But he hopes to continue to combine storytelling and science after graduation, perhaps as a science journalist or a podcaster.
