    Biography

    David Livingston is Deputy Director of the Dana-Farber/Harvard Cancer Center; Chief of the Charles A. Dana Division of Human Cancer Genetics, and the Emil Frei Professor of Genetics and Medicine at Harvard Medical School. From 1996 to 2000, he served as Chairman of the Executive Committee for Research at the Dana-Farber Cancer Institute, leading the senior faculty group that oversees all aspects of the Institute's research program. He reassumed that post in 2005 and has been in it since that time. Dr. Livingston has been a Harvard faculty member continuously since 1973.

    Dr. Livingston received an A.B. cum laude from Harvard College in 1961, an M.D., magna cum laude, from Tufts University School of Medicine in 1965, and served his internship and residency in internal medicine at the Peter Bent Brigham Hospital in Boston (now Brigham and Women's Hospital). In 1967, he became a Research Associate at the National Cancer Institute (NCI) in molecular biology and biochemistry; he continued his work as a Research Fellow in Biological Chemistry at Harvard Medical School in 1969. Dr. Livingston returned to NCI in 1971 as a Senior Staff Fellow where he began his career in cancer research. He was recruited to Dana-Farber (then the Childrens Cancer Research Foundation) in 1973.

    Dr. Livingston is an internationally recognized expert on genes that regulate cell growth in the body - genes that, when they go awry, can lead to cancer. These genes are called oncogenes and tumor suppressor genes. Through his research, Dr. Livingston has uncovered detailed biochemical steps required to initiate and maintain the transformation of these cells into tumor cells. His focus is on the regulatory controls of signal transduction - the smooth and coordinated flow of special chemical signals from the surrounding environment to the cell, where it is transduced into specific commands that tell cells whether or not to grow - and their role in cancer development. In recent years, his work has centered on those key molecular steps that trigger the development of breast and ovarian cancer.

    Dr. Livingston is the recipient of numerous awards and honors. He has been elected to the Institute of Medicine of the National Academy of Sciences, the National Academy of Sciences, itself, and the American Academy of Arts and Sciences. He sits on multiple editorial boards, the science advisory boards of other research institutions, and is a member of the Association of American Physicians, the American Society for Clinical Investigation, the American Society for Microbiology, and the American Academy of Microbiology. He is also a Foreign Associate of the European Molecular Biology Organization and serves as Vice Chair of the Board of the Damon Runyan Cancer Research Foundation. Dr. Livingston has authored more than195 scientific publications.

    Research

    Molecular Pathogenesis of Breast and Ovarian Cancer

    Our laboratory is dedicated to the study of processes that, when defective, allow human cells to develop malignant characteristics. These processes are, in part, controlled by tumor suppressor loci. We continue to concentrate our efforts on a subset of these loci, all of which exert their functions in the nucleus. Some participate in the control of cell proliferation, others in the control of genome integrity, and still others in mechanisms that underlie the ability of cells to thrive in low-oxygen environments and under other stresses. Based on some unexpected results, we have extended our work over the past two years to explore the events that give stem cells of certain tissues the ability to self-renew.

    A fraction of our effort is dedicated to understanding the genetics of breast and ovarian cancer development. In particular, we are studying the in vivo biochemical and biological functions of four genes - BRCA1, BRCA2, BACH1, and BARD1 - which encode large nuclear proteins that interact specifically with one another. At least three and likely all four of these proteins are products of tumor suppressing loci. Together, they function as parts of large nuclear complexes that participate in the response of cells to DNA damage, and perhaps in other basic functions as well. When BRCA1, BARD1, or BRCA2 is rendered defective by germline mutation in females, tumor development develops at higher than normal frequencies in the breast and the ovary. A major segment of our ongoing work is aimed at trying to understand how, in biochemical terms, BRCA1 and BRCA2 perform their tumor suppressing effects and why, in the case of BRCA1, these effects are detected in the cells of women but not men.
