University of Rochester Medical Center researchers have discovered that loss of muscle stem cells is the main driving force behind muscle decline in old age in mice. Their finding challenges the current prevailing theory that age-related muscle decline is primarily caused by loss of motor neurons. Study authors hope to develop a drug or therapy that can slow muscle stem cell loss and muscle decline in the future.Read More: Stem Cells May Be the Key to Staying Strong in Old Age

GDSC Graduate Justin Komisarof successfully defends
Friday April 28
Tuesday, May 2, 2017
MD/PhD candidate Justin Komisarof presented his work on the hunt for a common cancer gene signature. Building on prior work by the Land and McMurray labs, Justin used bioinformatic approaches to search for the presence of a ‘cooperation response gene’ (CRG) cancer gene expression signature a broad panel of different tumors. Using microarray gene expression datasets from GEO in colon, pancreatic, prostate, and head and neck cancers, Justin found a core set of consistently disregulated CRGs. A more in-depth study of genotype-phenotype correlation in colon cancer samples revealed that this CRG dysregulation did not track with p53 or Ras mutations, suggesting that CRG dysregulation occurs in multiple human cancers, and that the CRG expression pattern is independent of mutational status and may emerges as a function of the malignant state. Justin also applied this CRG-based analysis to prostate cancer samples and identified a core set of CRGs that when combined with clinical staging predicts recurrent outcomes with greater than 80% accuracy – a highly significant improvement over current methods. Justin’s work provides an important step forward for both diagnostic and future therapeutic approaches.

Michael John Beltejar awarded CTSI Pilot Trainee Grant
Thursday, April 13, 2017
Michael John Beltejar, a 4th year student in the Genetics, Development, and Stem Cells PhD program with a research focus in Genetic contributions to bone strength has been awarded CTSI Pilot Training Grant.
CTSI Pilot Trainee Grant RFA
A major priority for the CTSI is the active support of research collaborations via cross-disciplinary collaboration, and the support of research that addresses significant problems related to population health. Thus, applications directly addressing these areas are strongly encouraged. Trainee awards help awardees obtain the most prestigious fellowship possible following the project. The project should be part of a long-term plan to become an independent investigator. The award provides a maximum of $25,000 for a period of one year.
Osteoporosis remains a significant concern. By 2025, osteoporotic fractures are expected to increase to 3 million with an estimated cost of $25.3 billion. Morbidity and mortality increases following all major fractures in patients over 55 years of age. It is widely understood that compromised bone strength is the underlying pathophysiology of osteoporosis. Currently, bone mineral density (BMD), is the basis for diagnosis and the main target for osteoporosis therapy. BMD is an important clinical tool, but explains only 55 % of fractures, leaving the needs of 45% of patients unaddressed. Fundamentally, bone strength has two interconnected but distinct components: quantity and quality. While BMD reflects quantity, bone quality (BQ) reflects morphologic and compositional properties. However, developing therapies based on BQ is limited by two major gaps in knowledge: 1) Which genes regulate BQ and 2) Does estrogen deficiency modify the genetic regulation of BQ? Therefore, the objective of the work proposed is to construct a genetic network to identify candidate genes regulating bone composition(SA1) and determine if estrogen deficiency interacts with these genes(SA2).
The rationale for the proposed work is that bridging these gaps in knowledge is a crucial first step in the identification of novel therapeutics. The results produced from SA1 will inform ongoing research in the lab--in particular, a genome-wide association study identifying locations in the genome that are responsible for bone quality. Secondly, the results of SA2 have a strong potential to unlock research on multiple levels osteoporosis management. Identification of novel genes could be used as a new biomarker to identify at risk individuals earlier. Downstream activity of these genes could become additional metrics to monitor disease progression. Finally, these genes become putative targets for novel therapies. The research in this application is innovative because it is a significant departure which shifts focus from BMD to BQ as an equally important contributor of fracture resistance.
GDSC Student to join the Steven’s Laboratory at Harvard Medical

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 Biology

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.

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.

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

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

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

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.

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.

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.

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.

Researchers in the Department of Biomedical Genetics have unraveled one of the key molecular mechanisms that regulate stem cell behavior, a discovery that could provide important insight into regenerative medicine and certain forms of cancer.
The study – led by Benoit Biteau, Ph.D. – appears in the journal Cell Reports, and was conducted in fruit flies, or drosophila. While diminutive in stature, fruit flies have proven to be an invaluable research tool and have made oversized contributions to medicine, particularly in the fields of molecular biology and genetics.
Benoit and his colleagues focused on a transcription factor called Sox21a which is uniquely found in the stem cells of the drosophila intestine. Transcription factors are proteins that control the expression of genes and, subsequently, help regulate cellular activity. Sox21a is the equivalent of Sox2, a transcription factor found in humans that is known to play an important role in the function of stem cells and cell reprogramming.
