Geroscientists are united in the belief that basic research on the fundamental mechanisms of biological aging are the major risk factors of virtually all of the major geriatric disorders and that such knowledge has great potential to lead to major delays, ameliorations and, perhaps, preventions of many such disorders.

George M. Martin, M.D.

Emeritus Professor of Pathology, University of Washington

Dr. Martin received his BS and MD degrees from the University of Washington and has been a member of its faculty since 1957. After an internship at the Montreal General Hospital and a residency in anatomic pathology at the University of Chicago, he pursued postdoctoral research in somatic cell genetics under Professor Guido Pontecorvo at Glasgow University, where he worked with Aspergillus nidulans and human cell cultures. Other postdoctoral experiences have included research in molecular biology with Francois Gros in Paris and in experimental embryology with Henry Harris and Richard Gardner at Oxford University. He has also done medical genetics fieldwork in India.

Dr. Martin’s research has focused upon what he has characterized as segmental progeroid syndromes, virtually all of which were shown to support a major role for genomic instability as a fundamental mechanism of aging.

FOCUS AREAS

  • Alzheimer’s Disease Research. Dr. Martin assembled a team of investigators to carry out a linkage analysis of familial Alzheimer disease, an effort that led to the assignment of the most common form to chromosome 14 and to the mapping and positional cloning of a related locus on chromosome 1. Polymorphisms at that locus were shown to play a role in the susceptibility to Alzheimer disease in very old individuals.

  • Genetic Approaches to Aging. His work consists of data on mutation frequencies in human epithelial cells in aging human subjects. These studies were reinforced by a long series of investigations of human progeroid syndrome, the Werner syndrome, a recessive mutation that Dr. Martin’s group and Japanese investigators mapped to chromosome 8. Dr. Martin and colleagues have provided molecular evidence for the importance of intragenic deletions in somatic cells of Werner syndrome subjects. Cells from these patients were also shown to undergo accelerated "aging in vitro" . This latter line of research provided the first evidence for the limited replicative potential of cells of the vascular wall. Together with Drs. Tom Norwood and William Pendergrass, the Martin lab also carried out the first cell fusion experiments for the investigation of dominance/recessivity relationships between old cells, young cells and "immortal" cells and demonstrated that the decline of growth potential involved gradual and variable attenuations of clonal growth.

Awards and Honors

  • Brookdale, Kleemeier and Paul Glenn Foundation awards of the Gerontological Society of America, the Irving Wright Award of the American Federation for Aging Research, the American Aging Association Research Medal and Distinguished Scientist Award, the Pruzanski Award of the American College of Medical Genetics, a World Alzheimer Congress Lifetime Achievement Award and election to the National Academy of Medicine. 

  • He has also had the honor of having served as Past Presidents of the Tissue Culture Association, the Gerontological Association of America and the American Federation for Aging Research.
