Two U-M medical researchers win top national awards Huda Akil, Ph.D., and Gilbert S. Omenn, M.D., Ph.D., honored by Association of American Medical Colleges at annual meeting A neuroscientist who probes the intersection between brain biology and mental health, and a physician who has led national health care change for decades, today received top national awards for their achievements. Both are leaders at the University of Michigan Health System, and faculty at the U-M Medical School. In fact, U-M is the only institution with two winners among the 10 recipients of this year’s six top awards from the Association of American Medical Colleges, or AAMC. The awards were presented at the AAMC’s meeting in Philadelphia.

David E. Rogers Award:

Gilbert S. Omenn, M.D., Ph.D. Fittingly, Omenn was inspired early in his career by the physician leader for whom the award is named – and went on to make the major contributions to improving the health and health care of the American people that the award recognizes. Omenn is a U-M professor of Computational Medicine and Bioinformatics, Internal Medicine, Human Genetics, and Public Health. He directs the university-wide Center for Computational Medicine and Bioinformatics as well as the global Human Proteome Project. From 1997 to 2002, he was CEO of the U-M Health System and U-M executive vice president for medical affairs, during the pivotal years of forming a modern academic medical center. Over five decades, “Gil made fundamental basic scientific contributions, led major public health studies and initiatives, championed the role of academic medical centers, and played a key role in forming health policy for our nation,” says David Ginsburg, M.D., his U-M colleague and past AAMC Distinguished Research Award winner.

" A global hunt for genes that influence heart disease risk has uncovered 157 changes in human DNA that alter the levels of cholesterol and other blood fats – a discovery that could lead to new medications. The huge scan of genetic variations linked to blood lipid levels used an advanced device called a Metabochip. Each of the changes points to genes that can modify levels of cholesterol and other blood fats and are potential drug targets. Many of the changes point to genes not previously linked to blood fats, also called lipids. A surprising number of the variations were also associated with coronary artery disease, type 2 diabetes, obesity, and high blood pressure. The research also reveals that triglycerides – another type of blood lipid – play a larger role in heart disease risk than previously thought. The results, published in a paper and a letter appearing simultaneously in the journal Nature Genetics, come from the Global Lipids Genetics Consortium -- a worldwide team of scientists who pooled genetic and clinical information from more than 188,000 people from many countries and heritages. The analysis of the combined data was led by a team from the University of Michigan Medical School and School of Public Health. They used sophisticated computing and statistical techniques to search for genetic variations that modify blood lipid levels. The results increase by more than a third the total number of genetic variants linked to blood lipids. All but one of the variants associated with blood lipids are near stretches of DNA that encode proteins. “These results give us 62 new clues about lipid biology, and more places to look than we had before,” says Cristen Willer, Ph.D., the lead author of one paper and an assistant professor of Internal Medicine, Human Genetics and Computational Medicine & Bioinformatics at the U-M Medical School. “Once we take the time to truly understand these clues, we’ll have a better understanding of lipid biology and cardiovascular disease -- and potentially new targets for treatment.” But, cautions senior author and U-M School of Public Health Professor Gonçalo Abecasis, Ph.D., it will take much further work to study the implicated genes and to find and test potential drugs that could target them. The consortium’s “open science” approach will include publishing further detail online for other researchers to use freely toward this goal. A further analysis of the dataset, published as a letter with lead author Ron Do, Ph.D. and senior author Sekar Kathiresan, M.D. from the Broad Institute and Massachusetts General Hospital, suggests triglyceride levels have more impact on coronary artery disease risk than previously thought."

Kraig Stevenson
Gene expression is a critical step in translating information from DNA sequences into living cells. The first step of this process involves the transcription of DNA into RNA. Quantifying the abundance of RNA within an an organism thus provides important readout of cellular function. In recent years, advances in high-throughput sequencing have provided new ways to make these measurements. Importantly, they allow not only the total abundance of RNA within a sample to be determined, but also the relative proportion of RNA molecules from a particular gene that come from the maternal and paternal alleles. Unfortunately, with the most common computational methods used to analyze these data, measurements of allele-specific expression often show a systematic bias favoring detection of one allele over the other. In a new paper published by Bioinformatics graduate student Kraig Stevenson, postdoc Joseph Coolon, and CCMB faculty member Patricia Wittkopp, the sources of this systematic bias (as well as sources of other erroneous measures of allele-specific expression) are identified. By identifying the causes of these problems, this work paves the way for improving computational methods used to study allele-specific gene expression.

Alex Kip (Writer/Actor)
Ora Pescovitz, M.D., Norman Hogikyan, M.D., and Joel D. Howell, M.D., to participate in “talk-back” sessions after performances. James Cavalcoli, Ph.D., featured in production. Two years after graduating from the University of Michigan, an event that was immediately preceded by a terrifying diagnosis of cancer that threatened to end his career, actor and playwright Alex Kip has penned a play inspired by his experience. My Other Voice will premiere in Ann Arbor at the Arthur Miller Theatre at U-M Thursdays – Sundays from Aug.15-Sept. A special Aug. 25 performance will feature a “talk-back” session hosted by U-M EVPMA/UMHS CEO Ora Pescovitz, M.D. The session will allow audience members to speak openly about challenges of the physician’s role in cancer care and will also encourage physicians to dialogue with patients. Norman Hogikyan, M.D., professor and chief of Laryngology, Rhinology and General Otolaryngology will host a talk-back session with patients and audience members on Aug. 30 about specific vocal-related issues and health. Additional talk-back sessions will be announced for the Medical Arts Program, coordinated by Joel D. Howell, M.D., Ph.D., professor of Internal Medicine, Health Management and Policy, and History. In May, Pescovitz described Alex as “the epitome of courage” and praised his ability to “reinvent himself as a person and artist” on her blog, Medicine that Speaks. “It can be easy to give up and become a victim of circumstance.” says Pescovitz. “It is not easy to confront and surmount obstacles that get in the way of your dreams. Yet, that’s what Alex has done.” Kip, 25, a native of Columbus, Ohio, received his BFA in musical theatre from U-M and is also a graduate of the London Dramatic Academy. He was given a 15-30 percent chance of survival after being diagnosed with non-Hodgkins lymphoma as a senior at U-M. During subsequent treatment at the U-M Medical Center, Kip lost his voice. “No longer able to speak or sing,” he says, “I had to find a new identity.” Now in complete remission, Kip wrote “My Other Voice” with the goal of providing inspiration and hope to other cancer patients, particularly young adults, whose survival rate for cancer has not improved at the same rate as other age groups. James Cavalcoli, Ph.D., assistant professor of Computational Medicine and Bioinformatics, will play the role of Dr. Foster in the performance. “My hope is that this play will spread awareness of the unique difficulties young adults experience when diagnosed with cancer, while also giving patients hope for the future,” says Kip. “It will also be used as a teaching tool for doctors in training, or help this underserved group secure the age-appropriate resources they need. I want it to act as a patient advocate for young adult cancer victims.” Prior to the play’s upcoming premiere, it received several readings with industry professionals in New York City and had a staged reading in Columbus, Ohio. The Ann Arbor production will feature U-M faculty, students and other industry professionals both on stage and behind the scenes. For more information, visit www.myothervoice.org .

Jeffrey Kidd, Ph.D.
"More than 7 billion people live on this planet – members of a single species that originated in one place and migrated all over the Earth over tens of thousands of years. But even though we all trace our family lineage to a few common ancestors, scientists still don’t know exactly when and how those few ancestors started to give rise to the incredible diversity of today’s population. A brand-new finding, made using advanced analysis of DNA from all over the world, sheds new light on this mystery. By studying the DNA sequence of Y chromosomes of men from many different populations, scientists have determined that their male most recent common ancestor (MRCA) lived sometime between 120,000 and 156,000 years ago. It’s the first time the human ancestry has been traced back through the male line by sequencing the DNA of many entire Y chromosomes. And, it agrees reasonably well with previous findings about our female most recent common ancestor, made by studying DNA carried down through the human race’s female line. Such studies used DNA from mitochrondria -- structures inside cells – and placed that time of the most recent common ancestor between 99,000 and 148,000 years ago. That agreement makes the new finding especially significant: The research was done by a team of scientists from Stanford University, the University of Michigan Medical School, Stony Brook University, and their colleagues, and is published in the journal Science. The team hopes their work will lead to further research on Y chromosomes as vehicles for studying human history – and tracing male lineages back to the common “Adam” ancestors. Jeffrey Kidd, Ph.D., an assistant professor in U-M's departments of Human Genetics and Computational Medicine & Bioinformatics who worked on the new study, notes that only recently has it become possible to sequence Y chromosomes, because of technical limitations of previous approaches. The new paper details how the team was able to make reliable measurements of the sequence variation along the Y chromosome – which is handed down only from father to son without exchanging, or recombining, genetic material with other chromosomes. Kidd notes that this initial paper on Y chromosome sequence diversity provides important first evidence that the male most recent common ancestor did not live more recently than the female most recent common ancestor. “We’re interested in understanding the historical relationships between many different human populations, and the migration patterns that have led to the peopling of the world,” he says. “We hope that others will make use of this approach and sequence additional chromosomes of interest that are related to the peopling of specific places.” The study involved Y chromosomes obtained through the Human Genome Diversity Project, and from other sources. It included chromosomes from 69 men in several populations in sub-Saharan Africa, and from Siberia, Cambodia, Pakistan, Algeria and Mexico. The great migrations of our ancestors out of Africa, across Asia and Europe and into the Americas all helped shape today’s populations – as did more recent forces related to colonialism and ever-growing global mobility. Genetic studies such as this one may help anthropologists understand those migrations – and their timing – even better by giving them a genetic “clock” to use when studying today’s humans, or potentially DNA extracted from ancient bones. It may also help scientists understand the great genetic diversity seen across Africa, and the evolution process that led to modern humans. The reconciliation of the timing of ancestors some might call “Adam” and “Eve”, however, may be this study’s most important immediate implication. “This has been a conundrum in human genetics for a long time,” said Carlos D. Bustamante, Ph.D., a professor of genetics at Stanford and senior author of the study. “Previous research has indicated that the male MRCA lived much more recently than the female MRCA. But now our research shows that there’s no discrepancy. In fact, if anything, the Y chromosome may be a bit older.” In addition to Kidd and Bustamante, the research team includes U-M’s Elzbieta Sliwerska, Stanford’s G. David Poznik, Brenna M. Henn, Muh-Ching Yee, Ghia M. Euskirchen, Alice A. Lin, Michael Snyder, and Peter A. Underhill, and Lluis Quintana-Murci from Institut Pasteur in Paris.

John V. Moran
"The American Society of Human Genetics (ASHG) has named John V. Moran, Ph.D., Professor of Human Genetics and Professor of Internal Medicine in the Department of Internal Medicine at the University of Michigan, as the 2013 recipient of the Curt Stern Award. This annual award, named in honor of the late pioneering geneticist Curt Stern, Ph.D., recognizes researchers who have made significant scientific contributions during the past decade. ASHG will present the award, which will include a crystal plaque and cash prize, on Saturday, October 26, during the organization’s 63rd annual meeting in Boston. Dr. Moran, a Howard Hughes Medical Institute Investigator, has been a leader in research on genome instability and the biology of DNA sequences that can change their position in the genome, creating or reversing mutations and altering the genome’s size. Among his accomplishments is the discovery that processed pseudogenes are formed in the genome by the reverse transcriptase enzyme for the mobile DNA element referred to as L1. He developed the cell culture assay used in this research. His finding that the L1 insertion can lead to deletions in the genome has been confirmed by human genome analysis as well as numerous other studies, demonstrating the importance of retrotransposition in shaping the human genome through evolutionary time, and showing that these L1 insertions occur much more frequently than previously thought. The Curt Stern Award also recognizes Dr. Moran’s mentorship of graduate students and postdoctoral researchers as well ask his stalwart support of and service to ASHG."
