Leigh Wexler Graduates!

Friday, September 6, 2019

Dr.Leigh Wexler and Dr. Portman (From Left)

Congratulations to Dr. Leigh Wexler, who successfully defended their thesis this week, earning a Ph.D. in Genetics from the GDSC program. Leigh’s thesis research in the Portman Lab focused on the regulation of neuronal circuit function and behavior in the nematode C. elegans. It’s been known for many years that males of this species tend to leave a food source to find mates, but that depriving males of food causes them to reprioritize feeding behavior over exploration. One important component of this behavioral flexibility is regulated chemosensory function. Well-fed males detect food poorly, partly due to low expression of a food-associated chemoreceptor called ODR-10, but food-deprived males upregulate ODR-10, increasing food attraction and decreasing food-leaving behavior. In contrast, hermaphrodites (the female equivalent in C. elegans) are strongly attracted to food and exhibit high levels of ODR-10 expression even when well-fed.

Leigh’s research probed the mechanism by which ODR-10 expression is influenced by feeding status in males. They found that signals through two conserved pathways, involving the TGFβ-family ligand DAF-7 and the insulin-like (IIS) receptor DAF-2, are important for keeping ODR-10 expression low in well-fed males. Further, Leigh found that males in which the IIS pathway is constitutively active fail to upregulate ODR-10 when starved. Interestingly, the DAF-7 signal appears to act upstream of IIS, indicating that a cascade of neuroendocrine interactions is necessary for repressing ODR-10. And DAF-7 does not act as a sensor of the starved male’s physiological state, but rather conveys information about the presence of food in the environment.

Together, Leigh’s research demonstrates that C. elegans males assess their external state, rather than their metabolism, when deciding whether to take the risk of leaving food to find a mate, and that this occurs through a multistep neuroendocrine feedback loop. Leigh’s work also provides important insights into how internal and external states are integrated by the nervous system to influence gene expression, neuronal circuit function, and behavior. This work will appear in an upcoming issue of Current Biology. We wish Leigh all the best as she set out to Boston, to start her post-doctoral career in the laboratory of Max Heiman at Harvard.

Deb Fowell Authors Study on Immune Cell Navigation Systems

Tuesday, August 13, 2019

 

When immune cells get recruited to infections, tumors, or other sites of inflammation they exit the blood stream and begin searching for the damage. But how they effectively traverse the body’s tissue and home in on their targets is unclear. A new study led by Deborah Fowell, Ph.D. suggests that T cells have distinct navigation systems that help them pinpoint their targets.

Fowell’s research team, based in the David H. Smith Center for Vaccine Biology and Immunology in the Department of Microbiology and Immunology made the discovery by visualizing the immune system in real time using intravital multiphoton microscopy. The technology allows you to look directly into the skin and observe the dynamic behavior of immune cells ‘live.’ Their findings were published earlier this month in the journal Immunity.

“We thought that locating the infection foci was a passive event for immune cells; that they used the tissue as a scaffold to weave their way through this complex matrix to get to their target,” said Fowell, Dean’s professor in the Department of Microbiology and Immunology. “We discovered that they are pre-programmed to respond to certain cues within the tissue microenvironment that help them find their targets more efficiently.”

The team hopes that discovering these specialized programs for migration in tissues will provide new therapeutic targets that enable manipulation of the immune response in a disease-specific or tissue-specific fashion, rather than globally suppressing the immune system. Possibilities include boosting protective immunity in diseases where the immune system is inefficient, such as chronic infections and tumors, and limiting immunity in diseases that are exacerbated by the immune system, like autoimmunity and heart disease.

Hen Prizant, Ph.D., a postdoctoral fellow in Fowell’s lab and Alison Gaylo-Moynihan, M.D., Ph.D., a former student in the lab are co-first authors. Graduate students Ninoshka R.J. Fernandes, Hannah Bell, Dillon C. Schrock, Tara Capece, Brandon Walling, and Christopher Anderson contributed to the study. Faculty members David Topham, Minsoo Kim, Alan Smrcka and James Miller are also authors.

Fowell credits the new finding to the power of NIH Program Project Grants (P01), which allow faculty, trainees and students to explore uncharted scientific territory and branch out among different disciplines. For example, the team reached across Elmwood Avenue to have conversations with astrophysicists and engineers on River Campus about how objects move through and are found in space. The P01 that funded the research was awarded to Fowell (PI) and Kim, Topham and Miller in 2014. 

Supriya Mohile Headlines MSTP 19th Annual Retreat

Monday, August 12, 2019

The Medical Scientist Training Program’s 19th Annual Retreat was held on August 9, 2019, at the Rochester Yacht Club. The retreat is an opportunity for the student body to gather to discuss science and welcome the incoming class. This year, the MSTP welcomed six new students: Maya Anand (Columbia University), Thomas Delgado (University of Florida), Svetlana Markova (Kharkiv National Medical University), Michael Meadow (UCLA), Gavin Piester (University of Rochester), and Victor Zhang (University of Rochester). 

2019 Incoming Students

This year’s Keynote address was given by Dr. Supriya Mohile, Professor of Medicine and Surgery at the University of Rochester, and was titled “Improving Care Delivery and Outcomes for Older Patients with Cancer and their Caregivers.” Dr. Mohile highlighted the need for geriatric assessments in oncology to properly address concerns such as tolerability and toxicity of cancer treatments. She described the large clinical studies that are ongoing which demonstrate the feasibility of implementing geriatric assessments in oncology and stressed the need for all clinicians who treat elderly patients to use tools available to them to address concerns that are unique to this population. 

The morning science session concluded with short talks by several current MSTP students. Second year medical student Emily Isenstein discussed her work on proprioceptive and visual integration in children with autism, Fara Tolibzoda Zakusilo (G2) discussed the role for the extracellular matrix in Alzheimer’s disease, Jesse Wang (G3) spoke about the development of a digital medical scribe, Booyeon Han (G4) described her work to understand the tumor-draining lymph node in pancreas cancer, and Aimee Morris (M4) spoke about resting state functional connectivity in focal dystonia. 

Following lunch, Kerry O’Banion, MSTP director, gave an update on curricular changes occurring in the medical school, which was followed by a presentation by students who attended the National MD/PhD Conference at Copper Mountain in July. New students were elected to the MSTP student council to end the afternoon. We look forward to another exciting year for the MSTP!

SMD's Aleta Anthony Named Director of Equity, Inclusion & Research Education Support

Friday, August 9, 2019

The Office for Graduate Education and Postdoctoral Affairs (GEPA) at the School of Medicine and Dentistry has announced the appointment of Aleta Anthony to the role of Director of Equity, Inclusion and Research Education Support. 

The directorship is a newly-created position aligning with the University of Rochester and the Medical Center’s broader mission to support equity and inclusion through strategic efforts, organizational programming, and inclusion initiatives. As director, Aleta will provide leadership and direction to GEPA to foster an environment where all members of the GEPA community are supported and acknowledged for diverse backgrounds and experiences. 

In a commitment to promoting equity and inclusion for students and postdocs, Richard Libby, Ph.D., who is senior associate dean for GEPA, worked with the University of Rochester Medical Center’s Office for Inclusion and Culture to create Anthony’s new role. 

Anthony joined the School of Medicine and Dentistry in 2017 as the director of graduate enrollment for Ph.D., master’s, and certificate programs. In addition to her new role leading GEPA’s equity and inclusion efforts, she will continue her work building and enhancing recruitment strategy for the school’s biomedical sciences and health sciences graduate programs.

Single Brain Region is Key to Assessing the Impact of Repetitive Head Hits, Concussions

Wednesday, August 7, 2019

While a brain injury can be difficult to locate, new research identifies a single region of the brain that can be used to examine the impact of a concussion or repeated hits to the head.

The finding, published today in Science Advances, also supports the emerging idea that traumatic brain injury is not limited to people who sustain a concussion; it can result from repetitive head hits that are clinically silent–those that do not produce the visible signs or symptoms of a concussion. These subconcussive hits have been increasingly recognized as a potential threat to long-term brain health and as a possible cause of chronic traumatic encephalopathy (CTE).

Jeffrey Bazarian, M.D., M.P.H., professor of Emergency Medicine, Neurology, Neurosurgery and Public Health Sciences at the University of Rochester Medical Center and a co-author of the study says that the location of a brain injury varies widely from person to person. This is a major obstacle for physicians trying to diagnose brain injury using imaging techniques.

“This study is important because we found that no matter where the head gets hit, the force is translated into a single region of the brain known as the midbrain,” noted Bazarian, who treats concussion patients and conducts research related to traumatic brain injury. “Midbrain imaging might be a way in the future to diagnose injury from a single concussive head hit, as well as from repetitive sub-concussive head hits.”

University of Rochester fourth-year medical student Adnan Hirad, Ph.D., the first author of the research added, “Our findings do not dispute the fact that head-injury effects are distributed throughout the brain, but the midbrain may serve as a ‘canary in a coal mine’ in terms of identifying damage. From this study we know that the midbrain region, which is linked to brain functions often affected by a concussion, is the place to look to identify the impact of clinically defined concussions with visible symptoms and silent brain injuries that can’t be observed simply by looking at or behaviorally testing a player, on or off the field.”

Congratulations MJ

Thursday, July 11, 2019

After successfully defending his thesis, MJ has completed the PhD portion of his MD/PhD studies. MJ’s studies investigated the genetic basis of bone-matrix quality, an underappreciated property of bone that contributes significantly to bone strength and is of great clinical importance for understanding of bone pathology such as osteoporosis. MJ used both a classical population genetics approach as well as a systems genetics approach, and found that bone matrix characteristics such as morphology and matrix composition are indeed inheritable properties. In addition, using an estrogen-deficient model of post-menopausal bone loss, he was able to identify gene networks that may play an important role in osteoporosis.  His results suggest that bone matrix quality is influenced by genetics and participates in maintaining tissue-level mechanical properties. Furthermore, identifying putative regulatory genes is clinically significant as they are presumptive targets for developing novel therapeutics. During his thesis work, MJ was the recipient of a CTSI Pilot Trainee Grant and scored a fundable F31 predoctoral fellowship from NIAMS. With his GDSC doctorate in hand MJ will return to medical school to obtain his M.D.  Best of luck in your future ventures, MJ!!

Scott Friedland Defends Thesis

Thursday, July 11, 2019

This week M.D./Ph.D. student Scott Friedland defended his doctoral thesis. Arriving at the GDSC in 2014, Scott pursued his Ph.D. under the mentorship of Dr. Aram Hezel. As a student Scott was granted travel awards to a national physician scientist conference and selective course at Cold Spring Harbor Labs. His thesis, titled Arid1a, a subunit of the SWI/SNF chromatin remodeling complex, is a barrier to KrasG12D-driven tumorigenesis, studied the role of SWI/SNF, a chromatin remodeling complex, in pancreatic function and disease, which has implications for the fields of cancer and developmental biology. These findings may, in time, impact the treatment of diseases such as pancreatitis and pancreatic cancer. Scott will be reinitiating his medical education alongside the class of 2021 here at the University of Rochester School of Medicine, and is interested in pursuing a career as an oncologist and cancer researcher.

Study Points to Stabilization of TRAF3 Protein to Fight Age-Related Bone Loss

Wednesday, June 26, 2019

A new study led by Brendan Boyce, M.B.Ch.B.., professor of Pathology & Laboratory Medicine and the Center for Musculoskeletal Research and Zhenqiang Yao, MD., Ph.D., assistant professor of Pathology & Laboratory Medicine suggests that age-related osteoporosis could be prevented or treated through pharmacologic stabilization of the protein, TNF receptor-associated factor 3 (TRAF3).

The collaborative study was published in Nature Communications after five years of work by Boyce and fellow URMC researchers who note the need to better understand the mechanisms through which osteoporosis occurs in order to develop new drugs that can be given to help prevent or reverse the disease.

The study notes that the process by which young, healthy peoples’ bones are naturally rebuilt, deteriorates as people age or go through menopause. Increased inflammation, or inflammaging, leads to an increase in bone-degrading osteoclast cells and a reduction in bone-forming osteoblasts, resulting in osteoporosis.

Existing treatments that prevent bone destruction offer long term solutions, but many patients are reluctant to take them because they fear side effects of the drugs, while bone forming drugs can be administered only for short periods to help patients suffering from chronic osteoporosis.

The paper shows that the protein, TGF-beta, which is released in increasing amounts from bone during aging, causes breakdown of TRAF3 in osteoblast precursor mesenchymal progenitor cells. This leads to a reduction in the number of osteoblasts and less bone repair and indirectly to increased numbers of osteoclasts and more bone destruction.

By stabilizing TRAF3 levels in bone cells through new drugs, the authors provide a novel mechanism for how treatments may offer a more long-term solution for patients. This is especially crucial as more people live longer and are exposed to a greater risk of fractures and early death.

A Graphic Design Revolution For Scientific Conference Posters

Tuesday, June 18, 2019

“Other templates didn't necessarily ask you to think about what you were putting on them because they allowed it all,” says Derek Crowe, a PhD student in biomedical genetics in Hucky Land's lab with a former career in visual communication and design, “In order to use Mike's layout though, my hand is forced.”

With the new template, scientists need to think about their core message, but some people have a difficult time figuring out how to do that, or how to use visuals to present their message. Without proper science communication training, even a better poster template doesn’t work.

Crowe has taken matters into his own hands. Not only does he teach a course on visual communication for scientists at the University of Rochester, but he also shared his poster design tips online. In a nod to Morrison’s “better poster”, Crowe’s is a “butter poster”. He provides step by step instructions on how to organize the poster, and how to think about the content in a visual way.

“Like the graphic novel did for literature, visual languages have the power to add more dimensions to scientific storytelling,” says Crowe, “I’m excited to see what happens as the greater science community begins to take advantage of well-established visual storytelling tools.”

Imaging That Twinkle in Your Eye: Assessing Vascular Health by Imaging Blood Cells in the Retina

Tuesday, May 14, 2019

Jesse B. Schallek, Ph.D., assistant professor in the Department of Ophthalmology, describes a new, noninvasive approach to assess vascular health in the journal eLife. Schallek’s lab, part of the Flaum Eye Institute, developed a method to visualize how single blood cells flow through vessels of the eye using adaptive optics imaging.

The transparency of the eye provides a natural window to the retina, an extension of the brain. Vascular physiology is best studied noninvasively inside the living body, but seeing the details of how microscopic blood cells interact within the vasculature has not been possible with current tools such as fMRI. Schallek’s team developed high-resolution adaptive optics combined with fast camera capture to visualize single-cell blood flow dynamics in the living mouse eye.

“We’re able to image single blood cells and measure their speed. Remarkably, this can be achieved in vessels of all sizes, from the smallest capillaries to the largest retinal vessels,” said Schallek. “This approach may eventually provide a view of patient vascular health without the need for blood draws or dyes.

Krystel Huxlin, Ph.D., Associate Chair for research in the Department of Ophthalmology adds, “This method has the potential to enable early diagnosis of cardiovascular disease and diabetic neuropathy, and will also be of interest to investigators studying blood flow in the context of stroke and neurodegenerative diseases like Alzheimer’s.

The study was conducted in large part by Optics graduate students Aby Joseph and Andres Guevara-Torres. “My research interest involves using my physics/optics background to provide insights into biological questions,” said lead-author Joseph. “This paper, at the intersection of physical sciences and neuroscience, provides a novel and noninvasive imaging approach that may advance our understanding of blood flow dynamics in brain and retinal vessels smaller than the width of a human hair.

Schallek’s team, part of the Advanced Retinal Imaging Alliance (ARIA), is now deploying the method in healthy human eyes to establish metrics that will enable researchers to better elucidate the events that initiate and propagate disease. A pre-clinical investigation, funded by the Dana Foundation, is beginning to use this powerful approach to compare what happens in normal and diabetic retinas of human subjects. Schallek holds secondary appointments in the Department of Neuroscience and the Center for Visual Science. The research was funded by the National Eye Institute at the National Institutes of Health and by a Career Development Award from Research to Prevent Blindness.

Jayme Olson earns (CTSI) Trainee Award

Tuesday, April 30, 2019

Jayme a GDSC-graduate student in the Palis Lab was recently awarded a Clinical and Translational Science Institute (CTSI) Trainee Award. This one-year fellowship will fund cutting edge work on the in vitro generation of human red blood cells.  Cultured human red blood cells (RBCs) have the potential to serve as a supplemental source of blood for transfusion therapy, and as a tool for clinical and research diagnostic. However, a major barrier in generating sufficient numbers of cultured RBCs cells is the limited ex vivo self-renewal capacity of adult-derived erythroblasts. Work in the Palis Lab has identified Bmi-1, a member of the polycomb repressive complex 1 (PRC1), as a critical regulator of erythroid self-renewal.  Bmi-1 also plays a role in normal erythroid precursor maturation. Jayme will test the hypothesis that Bmi-1 regulates erythroid self-renewal and terminal maturation using different PRC1 members. Ultimately, these proposed studies will pave the way for the generation of sufficient numbers of cultured RBCs for blood typing and transfusion therapy, as well as the establishment of in vitro models for the study of erythroid intrinsic diseases.
