• Elizabeth Petty selected to participate in ELAM
  ANN ARBOR, Mich.-- Elizabeth Petty, M.D., was chosen to join the 2009-2010 class of fellows in the only national program dedicated to preparing senior women faculty for leadership at academic health centers.
  
  ?I am delighted to participate in ELAM this year,? says Petty, associate dean of student programs and professor of internal medicine and human genetics at the University of Michigan Medical School.
  
  The Hedwig van Ameringen Executive Leadership in Academic Medicine Program for Women (ELAM) adapts lessons in executive management and institutional leadership, such as strategic finance, organizational dynamics, and personal and professional effectiveness, to the academic health center environment.
  
  One of Petty?s first assignments is to have a candid assessment done by her supervisors, peers and employees to help identify her current strengths and weaknesses.
  
  ?I anticipate that my participation in ELAM will provide me with additional knowledge, tools, talents, and resources that will positively impact my daily work at U-M,? Petty says.
  
  ELAM members receive the chance to meet with national leaders in the field and interact with their peers in the program, which is held at the Drexel University College of Medicine. They also begin a long-term project to address an institutional need or goal, while providing an opportunity for leadership and greater visibility.
  
  The goal of ELAM is to increase the number of women in senior leadership positions, which will in turn change the culture of academic health centers to become more inclusive of different perspectives and more responsive to changing social agendas.
  
  ?I am grateful for the opportunity to participate in this education program that will enhance my professional development and look forward to using the skills and knowledge I gain to better serve our institution,? Petty says. She added she admires the U-M Medical School female faculty who have participated in ELAM during previous years.

• Dr. John Kim of the University of Michigan Named 2009 Pew Scholar
  Philadelphia, PA - The Pew Charitable Trusts announced today that Dr. John K. Kim was selected as a 2009 Pew Scholar in the Biomedical Sciences. Awards this year were given to 17 early-career scientists who display outstanding promise in research relevant to the advancement of human health. As a Pew Scholar, Dr. Kim will receive a $240,000 award over four years to support his research and gains inclusion into a select community of scientists that encourages collaboration and the exchange of ideas.
  
  "Pew's Scholars Program in the Biomedical Sciences recognizes and supports promising young scientists in advancing human health," says Shelley A. Hearne, managing director of the Pew Health Group. "Unlike many traditional research grants with strict guidelines on how funds must be used, our program allows participants to try out new investigative directions as their research unfolds. Flexibility, we feel, is an important key to encouraging the scientific creativity that often leads to spectacular results."
  
  John K. Kim, Ph.D., received his doctorate in biochemistry and molecular biology from the University of California, Davis, in 2000. He conducted his postdoctoral research in genetics at the Harvard Medical School and Massachusetts General Hospital. In 2006, he joined the faculty of the University of Michigan as an assistant professor in the Department of Human Genetics at the Life Sciences Institute.
  
  In the last decade, small RNAs have emerged as major regulators of gene expression, important for many processes in mammals. Dr. Kim studies the detailed steps of how small non-coding micro-RNAs (miRNAs) recognize the genes that they regulate and direct them to be turned off. His work centers on the identification of a new group of proteins that bind to these miRNAs and the genetic sequences they target in the model organism C. elegans. By understanding the role that these newly identified proteins play in regulating known miRNA targets, his studies will provide crucial insights into what is now known to be a mode of gene regulation required for normal development and disease prevention.
  
  Now in its 25th year, the Pew Scholars Program in the Biomedical Sciences has invested more than $125 million to fund over 460 scholars. Many alumni have received prestigious awards, including the Nobel Prize, MacArthur Fellowships and the Albert Lasker Medical Research Award.

• U-M scientists selected as Howard Hughes Medical Institute investigators
  ANN ARBOR, Mich.?Two researchers at the University of Michigan have been appointed as Howard Hughes Medical Institute investigators.
  
  John V. Moran, associate professor of human genetics at the U-M Medical School, and Mercedes Pascual, associate professor of ecology and evolutionary biology at the U-M College of Literature, Science, and the Arts, are among 56 top scientists nationally who have been appointed as investigators, the institute announced Wednesday.
  
  Moran is a pioneer in understanding the biology of common repetitive DNA elements in the human genome often dismissed as ?junk? DNA. He leads a group of U-M researchers who examine how these repetitive elements impact the evolution of the human genome.
  
  Pascual is a theoretical ecologist who uses mathematical models to explore links between climate fluctuations and cycles of infectious diseases such as cholera and malaria. In 2002, Discover magazine named her one of "The 50 Most Important Women in Science."
  
  
  Mercedes Pascual
  The Howard Hughes Medical Institute is a non-profit medical research organization that ranks as one of the nation's largest philanthropies. In the past two decades, HHMI has made investments of more than $8.3 billion for the support, training and education of the nation's most creative and promising scientists.
  
  Selected from more than 1,070 researchers in a nationwide competition, the new HHMI investigators come from 31 institutions from across the country. The institute is committing more than $600 million over their first term of appointment.
  
  HHMI enters into long-term collaboration agreements with universities and other academic research organizations, where its investigators hold faculty appointments. Under these agreements, HHMI investigators, who are directly employed by the institute, and their research teams carry out their research in HHMI laboratories located on various campuses.
  
  The institute currently employs more than 300 of the nation's most innovative scientists, who lead Hughes laboratories at 64 institutions.
  
  Moran examines a class of ?jumping genes? called LINE-1 elements, which are a perplexing class of repetitive DNA in the human genome. These repetitive elements make up roughly 17 percent of human genetic material, but once were largely ignored and disparaged as ?junk.? The bulk of this ?junk? DNA appears to have been carried down from our distant evolutionary past and can be considered to be molecular fossils.
  
  Moran and his laboratory have shown that some LINE-1 elements can still jump and that their mobility can impact the human genome in a myriad of ways. The lab has developed tools from the fields of genetics, molecular biology and biochemistry to systematically study LINE-1 movement in cultured human cells.
  
  Moran continues to study why, when and how often LINE-1 elements jump to new locations, with the long-range goal of understanding how the process has influenced the evolution of the human genome and how the mobility of LINE-1 elements can occasionally lead to genetic diseases such as Hemophilia A, colon cancer and muscular dystrophy.
  
  Moran is an associate professor in the Department of Human Genetics at the U-M Medical School. He received a bachelor?s degree in chemistry at the Rochester Institute of Technology; a master?s degree in molecular genetics at Ohio State University; and a Ph.D. in biochemistry at the University of Texas Southwestern Medical Center.
  
  Moran is a past associate editor of the American Journal of Human Genetics and is on the editorial board of Gene. In 2003 he received the U-M Henry Russel Award. He is a past recipient of the W. M. Keck Foundation Young Scholar in Medical Research Award, the Basil O'Connor Starter Scholar Research Award, the Damon Runyon Scholar Award and a Postdoctoral Basic Science Research Award from the American Society of Human Genetics.
  
  Pascual is exploring the issue of whether and how global warming and climate variability are contributing to the spread of infectious diseases. In one project, she and collaborators in Barcelona and Bangladesh found evidence that a phenomenon called the El Nino-Southern Oscillation (ENSO), which is a major source of climate variability from year to year, influences cycles of cholera in Bangladesh. They also showed that the coupling between climate variability and cholera cycles has become stronger in recent decades. Pascual has been examining the feasibility of using a model developed during that work as an early warning system to predict cholera outbreaks.
  
  In other research, Pascual and her research group have studied the connection between global warming and the resurgence of malaria in East Africa and developed a model that couples evolutionary change and epidemiological dynamics to explain ups and downs in influenza epidemics during interpandemic periods.
  
  Pascual is an associate professor in the Department of Ecology and Evolutionary Biology. She received a Licenciatura degree in biology from Universidadde CienciasExactas y Naturales in Buenos Aires, Argentina; a master's degree in mathematics from New Mexico State University; and a doctorate in biological oceanography from the Joint Program of the Woods Hole Oceanographic Institution and the Massachusetts Institute of Technology.
  
  She was awarded a U.S. Department of Energy Alexander Hollaender Distinguished Postdoctoral Fellowship for studies at Princeton, and in 1999 received a Centennial Fellowship in Global and Complex Systems from the James S. McDonnell Foundation. In addition to her primary affiliation, Pascual is also associated with the U-M Center for the Study of Complex Systems and the Santa Fe Institute.
• U-M researchers release most detailed global study of genetic variation
  ANN ARBOR, Mich.?University of Michigan scientists and their colleagues at the National Institute on Aging have produced the largest and most detailed worldwide study of human genetic variation, a treasure trove offering new insights into early migrations out of Africa and across the globe.
  
  Like astronomers who build ever-larger telescopes to peer deeper into space, population geneticists like U-M's Noah Rosenberg are using the latest genetic tools to probe DNA molecules in unprecedented detail, uncovering new clues to humanity's origins.
  
  The latest study characterizes more than 500,000 DNA markers in the human genome and examines variations across 29 populations on five continents.
  
  "Our study is one of the first in a new wave of extremely high-resolution genome scans of population genetic variation," said Rosenberg, an assistant research professor at U-M's Life Sciences Institute and co-senior author of the study, to be published in the Feb. 21 edition of Nature.
  
  "Now that we have the technology to look at thousands, or even hundreds of thousands, of genetic markers, we can infer human population relationships and ancient migrations at a finer level of resolution than has previously been possible."
  
  The new study, led by Rosenberg and National Institute on Aging colleague Andrew Singleton, produced genetic data nearly 100 times more detailed than previous worldwide assessments of human populations. It shows that:
  
  ? A recently discovered type of human genetic variation, known as a copy-number variant or CNV, is a reliable addition to the toolkit of population geneticists and should speed the discovery of disease-related genes. Rosenberg and his colleagues discovered 507 previously unknown CNVs, which are large chunks of DNA?up to 1,000,000 consecutive "letters" of the genetic alphabet?that are either repeated or deleted entirely from a person's genome. Various diseases can be triggered by an abnormal gain or loss in the number of gene copies.
  
  ? It's sometimes possible to trace a person's ancestry to an individual population within a geographic region. While previous studies have found that broad-scale geographic ancestry could be successfully traced, the new results indicate "it's becoming increasingly possible to use genomics to refine the geographic position of an individual's ancestors with more and more precision," Rosenberg said.
  
  ? Human genetic diversity decreases as distance from Africa?the cradle of humanity?increases. People of African descent are more genetically diverse than Middle Easterners, who are more diverse than Asians and Europeans. Native Americans possess the least-diverse genomes. As a result, searching for disease-causing genes should require the fewest number of genetic markers among Native Americans and the greatest number of markers among Africans.
  
  The results are being made available on publicly shared databases.
  
  "I hope the study will be an invaluable resource for understanding genomic variability and investigating genetic association with disease," said the NIA's Singleton.
  
  The researchers analyzed DNA from 485 people. They examined three types of genetic variation: single-nucleotide polymorphisms, or SNPs; haplotypes; and CNVs.
  
  If the human genome is viewed as a 3-billion-letter book of life, then SNPs represent single-letter spelling changes, haplotype variations equate to word changes, and CNVs are wholesale deletions or duplications of full pages.
  
  The patterns revealed by the new study support the idea that humans originated in Africa, then spread into the Middle East, followed by Europe and Asia, the Pacific Islands, and finally to the Americas.
  
  The results also bolster the notion of "serial founder effects," meaning that as people began migrating eastward from East Africa about 100,000 years ago, each successive wave of migrants carried a subset of the genetic variation held by previous groups.
  
  "Diversity has been eroded through the migration process," Rosenberg said.
  
  In addition to his position at the Life Sciences Institute, Rosenberg is an assistant professor of human genetics at the Medical School; an assistant professor of biostatistics at the School of Public Health; an assistant professor of ecology and evolutionary biology at the College of Literature, Science, and the Arts; and an assistant research professor of bioinformatics at the Medical School's Center for Computational Medicine and Biology.
  
  "This data set is so rich. It provides a much more comprehensive, cross-sectional snapshot of the human genome than previous studies," said Paul Scheet, a post-doctoral researcher in the U-M Department of Biostatistics and one of the lead authors.
  
  "The next step for these studies is to sequence whole genomes," said Mattias Jakobsson, a post-doctoral researcher at the U-M Center for Computational Medicine and Biology and another lead author. "You would take 500 individuals, and you would just completely sequence everything, and then you'd have almost every important variant that's out there."
  
  The work was supported in part by National Institutes of Health grants, the U-M Center for Genetics in Health and Medicine, the Alfred P. Sloan Foundation, the Burroughs Wellcome Fund, the National Center for Minority Health and Health Disparities, and the Intramural Program of the National Institute on Aging.

  HHMI Adds 15 Patient-Oriented Researchers
  New Researchers Speed Translation of Basic Discoveries into Improved Treatments
  
  The Howard Hughes Medical Institute (HHMI) has selected 15 of the nation's top physician-scientists to be appointed as HHMI investigators in an initiative that underscores HHMI's commitment to ensuring that basic research discoveries are translated into improved treatments for patients. The Institute has committed approximately $150 million to their first term of appointment.
  
  
  ?The impact of their research is already being felt by people suffering from malaria in Africa, by those with post-traumatic stress disorder in the United States, and by people worldwide with leukemia or lung cancer.?
  Thomas R. Cech
  
  ?These 15 physician-scientists are changing the way we think about and treat a variety of diseases,? said HHMI President Thomas R. Cech. ?The impact of their research is already being felt by people suffering from malaria in Africa, by those with post-traumatic stress disorder in the United States, and by people worldwide with leukemia or lung cancer. As a group, they have demonstrated extraordinary creativity and innovation.?
  
  The new HHMI investigators, who come from 13 institutions from across the country, were selected in a nationwide competition that sought applications from researchers who lead patient-oriented research programs and whose scientific work is guided by their interaction with patients. These physician-scientists spend their professional lives crossing the boundaries between the laboratory bench and the bedside, convinced that patient care informs and enhances their research.
  
  This competition differed from previous competitions for new HHMI investigators because eligible researchers with faculty appointments at 121 institutions were invited to apply directly to HHMI. Prior institutional approval was not part of the process, as it had been for previous HHMI investigator competitions where a researcher's host institution nominated the candidate. The Institute received 242 applications from eligible candidates, of which 15 were selected to become HHMI investigators. To evaluate the applications, HHMI assembled review panels consisting of distinguished physician-scientists and biomedical scientists.
  
  ?We were pleased with the depth and breadth of candidates who applied in this competition,? said David A. Clayton, vice president for research operations at HHMI. ?This was the first time that HHMI solicited applications directly from individual faculty at leading institutions and the outcome is an unqualified success.?
  
  In 2002, the Institute completed its first competition dedicated to selecting physician-scientists who conduct patient-oriented research. In that competition, 12 new HHMI investigators were selected from 138 nominees. HHMI physician-scientists selected in the 2002 competition have identified new drug targets, developed new therapeutic agents, and improved our understanding of the genetic bases of several diseases that affect humans.
  
  Despite the potential benefit that can come from nurturing the careers of physician-scientists, there is abundant anecdotal evidence that the number of physician-scientists pursuing careers in patient-oriented research is declining in the United States, said Cech. ?We certainly don't have all the answers. But with the appointment of these new investigators ? who will also serve as mentors for the next generation of patient-oriented researchers ? and our early career awards to physician-scientists, we are sending a strong message that HHMI is committed to supporting the people who perform this vital work,? he said.
  
  In another program, HHMI announced earlier this year that it was expanding support for its Physician-Scientist Early Career Awards. In August 2007, the Institute selected 20 awardees and announced that it is investing $7.5 million to help ensure that promising physician-scientists have the resources they need to launch their careers. Each awardee is receiving $375,000 over a five-year period. When the Institute announced its first early-career awards in 2006, 13 physician-scientists received $150,000, awarded over a three-year period.
  
  Although some of the 291 current HHMI investigators are doing patient-oriented research, a large number of Hughes scientists focus on basic research directed toward understanding the genetic, molecular and cellular bases of human disease. Some of these projects can be generally characterized as being disease-oriented rather than patient-oriented, because the research does not require significant contact with patients.
  
  Applicants for the patient-oriented research competition were eligible to submit an application if they met the following requirements:
  
  
  Have an M.D. or M.D./Ph.D. degree or the equivalent
  Have a current license to practice medicine in the United States
  Be a tenured or tenure-track (or equivalent) faculty member at one of the 121 eligible host institutions on the date of submission of the application
  Have between four and 16 years of experience as an independent investigator
  Be engaged in the conduct of patient-oriented research
  Be the principal investigator on a funded NIH R01 grant or a project leader on a NIH P01 grant
  HHMI enters into long-term collaboration agreements with universities and other academic research organizations, where its investigators hold faculty appointments. Under these agreements, HHMI investigators, who are directly employed by the Institute, and their research teams carry out their research in HHMI laboratories located on various campuses. Through its flagship investigator program, HHMI has joined with more than 60 distinguished U.S. universities, hospitals, institutes, and medical schools to create an environment that provides flexible, long-term support for 291 Hughes scientists and members of their research teams.
  
  The Howard Hughes Medical Institute
  
  The Howard Hughes Medical Institute, a non-profit medical research organization that ranks as one of the nation's largest philanthropies, plays a powerful role in advancing biomedical research and science education in the United States. In the past two decades HHMI has made investments of more than $8.3 billion for the support, training, and education of the nation's most creative and promising scientists.
  
  HHMI's principal mission is conducting basic biomedical research, which it carries out in collaboration with more than 60 universities, medical centers and other research institutions throughout the United States. 291 HHMI investigators, along with a scientific staff of 2,200, work at these institutions in Hughes laboratories. The Institute's scientific research expenditures at the close of fiscal year 2007 totaled $613 million. HHMI grants totaled $86 million at the close of fiscal year 2007. The Institute's philanthropic grants program emphasizes initiatives with the power to transform graduate and undergraduate education in the life sciences. It also supports the work of biomedical researchers in many countries around the globe. Through aggregate investments of more than $1.2 billion, the Institute has sought to reinvigorate life science education at both research universities and liberal arts colleges and to engage the nation's leading scientists in teaching.
  
  At the end of its 2007 fiscal year, HHMI had an endowment of $18.7 billion. Its headquarters are located in Chevy Chase, Maryland, just outside Washington, D.C.
• Researchers find new gene linked to breast cancer.
  October 8, 2007
  
  Researchers find new gene linked to breast cancer
  
  Multicenter study suggests HMMR increases breast cancer risk
  
  HMMR interacts with BRCA1, suggesting new pathway for further research, study finds
  
  ANN ARBOR, MI ? Researchers in a multicenter international study have identified a new gene that, if mutated, may increase a woman?s risk of breast cancer by more than a third.
  
  Further, the researchers found that the gene, HMMR, interacts with the well-known breast cancer gene BRCA1. Alternations in either gene cause genetic instability and interfere with cell division, which could be a path to breast cancer developing. This leads researchers to not just a single gene, but a pathway that may be a potential target for treating or detecting breast cancer.
  
  Results of the study appear in the advance online edition of Nature Genetics.
  
  HMMR is mutated in about 10 percent of the population. Mutations in the two main genes involved in breast cancer susceptibility, BRCA1 and BRCA2, occur in about one of every 300 individuals, or less than 1 percent of the population.
  
  ?If we can identify variations of genes that are more common in the population that increase breast cancer risk, then targeting that gene for early detection or treatment will have a greater impact,? says Kristen Stevens, M.P.H., a doctoral student in epidemiology at the University of Michigan School of Public Health and one of the lead authors on the paper.
  
  The study was an international collaboration with researchers from Spain, Israel and several centers in the United States, including the U-M Comprehensive Cancer Center.
  
  Researchers started by developing a computerized network-modeling tool that allows many different types of existing scientific data sources to be analyzed easily to identify genes that impact cancer development. The researchers started with four genes already known to play a role in breast cancer ? BRCA1, BRCA2, ATM and CHEK2. They were then able to see how each of these genes interacts with other genes in the body. Through this model, HMMR emerged as a key player in breast cancer. The authors then showed that alterations of either BRCA1 or HMMR can lead to genetic instability and interfere with cell division.
  
  ?These findings made us wonder whether HMMR might also be a breast cancer susceptibility gene,? says study author Stephen Gruber, M.D., Ph.D., M.P.H., the H. Marvin Pollard Professor of Internal Medicine at the U-M Medical School. Gruber is an associate professor of internal medicine and of human genetics in the U-M Medical School, and of epidemiology in the U-M School of Public Health. He directs the Cancer Genetics program in the U-M Comprehensive Cancer Center, which focuses on inherited cancer risks.
  
  To understand whether variation in HMMR increases breast cancer risk, the researchers looked at the genes of 923 Jewish Israeli women with breast cancer and similar women without breast cancer in a study led by Gadi Rennert, M.D., director of the CHS National Cancer Control Center in Haifa, Israel. The Ashkenazi Jewish population in Israel carries a higher risk of breast cancer than other ethnicities.
  
  This component of the study found that women with a variation in the HMMR gene had a higher risk of breast cancer, even after accounting for mutations in the BRCA1 or BRCA2 genes. In particular, the risk of breast cancer in women under age 40 who carry the HMMR variation was 2.7 times the risk in women without this variation.
  
  The researchers further verified the finding in a second group of Ashkenazi Jewish women in New York who had a family history of breast cancer but no identified BRCA1 or BRCA2 mutations and a third study of Jewish women with and without breast cancer in New York. In total, 2,475 women with breast cancer and 1,918 healthy women were studied in Israel and New York.
  
  Overall, the risk of breast cancer was 23 percent higher in women who had one copy of genetic variant, and 46 percent higher in women who had inherited two copies. In addition, those women were diagnosed an average of 12 months younger than women from the control group, suggesting that HMMR is linked to early-onset breast cancer.
  
  ?Identifying genes involved in cancer in the general population is important, because not all of the causes of breast cancer have been found. Through discoveries such as this, someday we might be able to more precisely estimate a person?s risk of cancer based on their genes,? says study author Laura Rozek, Ph.D., a postdoctoral research fellow at the U-M Medical School.
  
  More than 180,000 Americans will be diagnosed with breast cancer this year, and 40,900 will die from the disease, according to the American Cancer Society. For information about breast cancer treatment at U-M, visit www.mcancer.org or call the U-M Cancer AnswerLine at 800-865-1125.
  
  In addition to the U-M authors, study authors were Miguel Angel Pujana, Jing-Dong Han, Lea Starita, Muneesh Tewari, Jin Sook Ahn, Gad Rennert, Victor Moreno, Tomas Kirchhoff, Bert Gold, Volker Assmann, Wael ElShamy, Jean-Francois Rual, Doublas Levine, Rebecca Gelman, Kristin Gunsalus, Roger Greenberg, Bijan Sobhian, Nicolas Bertin, Kavitha Venkatesan, Nono Ayivi-Guedehoussou, Xavier Sole, Pilar Hernandez, Conxi Lazaro, Katherine Nathanson, Barbara Weber, Michael Cusick, David Hill, Kenneth Offit, David Livingston, Jeffrey Parvin and Marc Vidal.
  
  Funding for the study was from the National Cancer Institute, the National Institutes of Health, the Breast Cancer Research Foundation, the Niehaus, Southworth, Weissenbach Foundation, and the Koodish Foundation.

• Nobel-winning pioneer in understanding cholesterol to give annual James V. Neel lecture at U-M
  ANN ARBOR, MI ? Joseph L. Goldstein, M.D., a noted molecular genetics pioneer at the University of Texas Southwestern Medical Center whose discoveries two decades ago laid the groundwork for the development of statin drugs to lower cholesterol and prevent heart attacks, will give the seventh annual James V. Neel Lecture at the University of Michigan on Thursday, May 17 at 3 p.m.
  
  The talk, sponsored by the U-M Department of Human Genetics, takes place at the Biomedical Science Research Building Auditorium, located at 109 Zina Pitcher Place on the University of Michigan medical campus. A reception and poster session will follow the lecture. For information, call 734-764-5491.
  
  The annual event honors James V. Neel, M.D., Ph.D., who founded the nation?s first human genetics department at U-M in 1956. Neel was among the first to foresee the role of genetics in the diagnosis and treatment of medical conditions. Goldstein continues to explore that role today.
  
  ?Dr. Goldstein is one of America?s most prominent cardiovascular scientists,? says Kim Eagle, M.D., a director of the U-M Cardiovascular Center.
  
  U-M Medical School Chief of Cardiovascular Medicine David Pinsky, M.D., also a director of the Cardiovascular Center, calls Goldstein ?one of the great scientific-medical thinkers of our time who has made a difference.?
  
  Goldstein and his longtime collaborator Michael S. Brown won a 1985 Nobel Prize for discovering a key protein on cell surfaces, the LDL receptor, that regulates how cholesterol is taken up in cells. Their work sparked a new understanding of heart disease and paved the way for drugs to treat it.
  
  At the University of Texas Southwestern Medical Center, the two men continue to collaborate in laboratory research on a group of gene-activating proteins key to the normal process of lipid synthesis, work that sheds light on several diseases ranging from heart disease to obesity to diabetes. Goldstein?s U-M talk, ?The SREBP Pathway: From Cholesterol Homeostasis in Cells to Neural Crest Defects in Embryos,? will explore aspects of his current research.
  
  Goldstein is a past president of the American Society for Clinical Investigation and was a member of the Governing Council of the U.S. National Academy of Sciences. He also chaired the Howard Hughes Medical Institute?s Medical Advisory Board and the Lasker Awards jury.
  
  Goldstein is an outstanding figure in the dwindling ranks of physician-scientists who both see patients and conduct basic laboratory research that focuses on discoveries and treatments relevant to real diseases, says Pinsky. ?It is important to have role models such as Dr. Goldstein to inspire the next generation of physician scientists.?
• One small snip from man; one giant leap for the genome
  ANN ARBOR, Mich.?Snips of DNA of only 270 people from just four world locations provide a reliable map of genetic disease variations in the human genome for nearly all populations around the world.
  
  U-M scientists evaluated the worldwide coverage of a database of genetic markers and variations spread across the genome, called the HapMap, which was released one year ago by an international research consortium.
  
  That team had identified about 4.5 million single-letter differences in DNA, called single nucleotide polymorphisms or SNPs (say Snips) from the genomes of the Yoruba people in Nigeria, Chinese from Beijing, Japanese from Tokyo, and a group of European Americans. Each population's particular collection of SNPs is called a haplotype, which is what the name HapMap refers to.
  
  The HapMap database of genetic markers allows researchers to select markers that will be useful to their studies and also to develop a standard set of markers to be used in studies of many diseases. However, until now, the extent to which the genetic variants in the HapMap database represented the rest of the world's populations had not been studied.
  
  "The variants in the HapMap provide a good set of markers to use to test for diseases such as diabetes in most human populations," said study author Noah Rosenberg, assistant professor in the Life Sciences Institute, the Bioinformatics Program and the department of Human Genetics at the U-M Medical School.
  
  Rosenberg's U-M group studies genetic variation across populations and wanted to find the extent to which the genetic variants in the HapMap would apply to populations that were not part of that project. His team collected data from 927 individuals in 52 different world populations and measured the proportion of variants in these populations that were already contained in the HapMap.
  
  "Initially we expected that there would be many parts of the world where the coverage by the HapMap was inadequate," Rosenberg said. "Instead, what we found was that the variation in the HapMap does a reasonable job of capturing the genetic variation in nearly all populations."
  
  Therefore, researchers like Rosenberg who study disease variants in populations will be able to use the HapMap to test genetic markers spread out across the genome to investigate any differences related to that disease. Rosenberg has previously shown that the geographic distribution of haplotypes strongly reflects human history, with a loss of diversity as distance increases from the human species' ancestral range in Africa. In fact, this history explains part of the current finding.
  
  "Except in some parts of Africa, where haplotypes are older and more distinctive, human populations have diverged recently enough that their haplotypes are fairly similar," Rosenberg said.
  
  "These variations are of interest not only for the study of human history but also for disease-related studies," said Rosenberg. "That we can use the history of human evolution in the search for disease genes turns out to be a very powerful idea."
  
  The paper "A worldwide survey of haplotype variation and linkage disequilibrium in the human genome" was published in the advance online version on the Nature Genetics website on October 22, 2006.
• Internationally Prominent Pioneer in Cancer Genetics to give 8th Annual James V. Neel Lecture
  
• New U-M Center for Genetics in Health and Medicine will help bridge the gap between science and medicine
  ANN ARBOR, MI ? One day in the not-so-distant future, a DNA test will be as much a part of an ordinary doctor?s visit as a blood pressure check. By scanning each patient?s unique genetic code, doctors will be able to predict which patients are most likely to develop a specific disease and select the most effective therapy for each patient.
  
  Research advances in genetics have the potential to transform the practice of medicine. But to achieve that potential, laboratory scientists and clinical researchers must work together to make the difficult transition from scientific discovery to clinical practice.
  
  To facilitate that transition, the U-M Medical School has created the Center for Genetics in Health and Medicine (CGHM). Funded with an initial $2.5 million grant from the U-M Medical School, the center?s overall mission is to enhance scientific interaction among U-M scientists and clinicians conducting genetics-related research in many different fields.
  
  ?Collaboration is the key to the future of genetic medicine, but our researchers are scattered in separate departments throughout the Medical School and across the University,? says Allen S. Lichter, M.D., Dean of the University of Michigan Medical School. ?This center will bring U-M clinicians and scientists together to focus on complex interdisciplinary research questions. It will provide specialized core laboratory facilities and the expertise required for advanced genetics research. In addition, the center will help train the next generation of physicians and scientists.?
  
  ?Just five years after the draft sequence of the human genome was published, genetics is beginning to permeate all fields of medicine,? says Sally A. Camper, Ph.D., the James V. Neel Collegiate Professor of Human Genetics and chair of the U-M Department of Human Genetics.
  
  ?The ?genomics era? presents us with a remarkable opportunity to improve diagnosis, prevention and treatment of human genetic diseases and to identify the risk factors for common, complex diseases ? such as diabetes, cardiovascular disease and cancer ? which have both genetic and environmental components,? Camper says.
  
  The link between genetics and medicine is fitting given the long and distinguished history of human genetics research in the U-M Medical School, according to Camper.
  
  ?The center will help us continue the legacy of James Neel, Lee Dice and other U-M visionaries who developed the field of human genetics and understood its seminal importance to medicine,? she says.
  
  In 1956, Neel created the U-M Department of Human Genetics ? the first academic department devoted to genetics at any medical school in the United States. Dice opened the first Hereditary Disease Clinic at U-M in 1941. Since then, many of today?s most prominent geneticists and physician-scientists have received their graduate or post-doctoral training at U-M.
  
  One of Camper?s immediate goals for the Center for Genetics in Health and Medicine is to nurture promising graduate students, research fellows, medical students and genetic counseling students who are preparing for careers in medical genetics by providing new interdisciplinary educational programs and financial support.
  
  ?We just awarded our first CGHM fellowships to two outstanding post-doctoral research fellows,? Camper says. ?And we hope to expand the fellowship program in the future.?
  
  The first recipient of a one-year fellowship from the genetics research center was Mathilde Malapel-Body, Ph.D., a research fellow in pathology who will study the link between Crohn?s disease and genetic variation in a gene called NOD2. Malapel-Body will work with Gabriel Nunez, M.D., the Paul De Kruif Professor of Academic Pathology, in the U-M?s Comprehensive Cancer Center.
  
  The second individual to receive a fellowship was Hee Chui Lee, Ph.D., a research fellow in geriatric medicine. Working with Ao-Lin Hsu, Ph.D. a professor of internal medicine, Lee will study genes that extend the lifespan of a worm called C. elegans.
  
  Camper says the new research center will have a core group of 30 to 40 U-M researchers from clinical and basic science departments across the University, and a larger group of affiliate members. She also plans to recruit four to six additional investigators, all of whom will have joint appointments in genetics and clinical medicine. Camper will serve as interim director of the new center until a permanent director is hired.
  
  Another immediate goal is to provide core laboratory support services and state-of-the-art technical facilities for use by researchers in the Medical School and across the University.
  
  A Family Studies Core Facility, staffed by genetic counselors and administrative staff, will be developed to assist investigators with clinical research. Staff will identify and recruit families and individuals who are interested in participating in research, obtain informed consent and medical histories, and collect blood or tissue samples for genetic analysis.
  
  A Genetic Analysis Core Laboratory will provide shared access to the expensive, high-tech equipment required to rapidly sequence and genotype blood and tissue samples for use in scientific and clinical research studies.
  
  An internal faculty steering committee has been appointed to develop and implement plans for the Center for Genetics in Health and Medicine. The committee includes Goncalo Abecasis, D. Phil., associate professor of biostatistics; Thomas M. Glaser, M.D., associate professor of human genetics and internal medicine; Stephen B. Gruber, M.D., Ph.D., associate professor of internal medicine, human genetics and epidemiology; Marci M. Lesperance, M.D., associate professor of otolaryngology; Donna M. Martin, M.D., Ph.D., assistant professor of human genetics and pediatrics and communicable diseases; Miriam Meisler, Ph.D., professor of human genetics; Richard R. Neubig, M.D., Ph.D., professor of pharmacology and associate professor of internal medicine; Elizabeth M. Petty, M.D., associate professor of human genetics and internal medicine; Julia E. Richards, Ph.D., associate professor of ophthalmology and visual sciences and epidemiology; Wendy R. Uhlmann, M.S., genetic counselor in internal medicine; Jeffrey S. Warren, M.D., professor of pathology; and Beverly Yashar, Ph.D., assistant professor of human genetics.
