Dr. Jan VijgJan Vijg, Ph.D. is Professor at the Buck Institute for Age Research, Novato, California. He is the author of more than 200 scientific publications and holds eight patents in research processes and methodologies. In 1989 he helped develop the MutaMouse™, the first transgenic animal engineered to detect gene mutations in a living organism. This allowed scientists to monitor the effects of toxic agents on mouse DNA in any of its tissues or organs. Since that time, he has developed new versions of this mouse model, which make it easy for researchers to monitor ongoing changes in DNA in different tissues or during various developmental stages of the mouse lifespan.
Research at the Vijg Lab is focused on genome instability and the mechanisms through which this may cause human disease and aging. Genome instability is generally considered as a cause of cancer since Theodor Boveri proposed, over 100 years ago, that cancer is based on aberrant chromosome combinations. When in the late 1940s it was discovered that low, daily doses of radiation accelerated symptoms of normal aging in rodents (including non-cancer, degenerative symptoms), the possibility was considered by such eminent scientists as Leo Szilard, Frank Macfarlane Burnet and Howard Curtis that genome instability could play a general role in the etiology of human aging and disease.
This possible connection between damage to the genome and aging found strong support in the discovery that heritable defects in genome maintenance are often associated with premature aging, as for example in Werner Syndrome and Hutchinson Gilford Progeria Syndrome. The DNA repair defects present in these conditions, and other defects as well, have been engineered in mice and shown to also cause premature aging in these animals. Interestingly, while such defects sometimes increase both cancer and non-cancer, degenerative symptoms, they often greatly reduce spontaneous tumor formation. This antagonism between cancer and aging is still incompletely understood. In general, research in this area has now begun to attract increased attention and is the main topic of his NIH program project “DNA repair, mutations and cellular senescence” which began in 1999.
