NIH Training Grant in Basic Aging Research
Abstract
As the U.S. population ages, it is increasingly important that we understand the molecular and cellular basis of aging. Aging is the major risk factor for a broad spectrum of pathologies including cardiovascular dysfunction, cancer, osteoporosis, osteoarthritis, type II diabetes and neurodegenerative disorders such as Parkinson's and Alzheimer's disease. It is generally accepted that at least some age-related molecular changes are causal factors in the onset of these diseases. It is also clear that individuals differ, both qualitatively and quantitatively, in how they age. Rational approaches to preventing and intervening in age-related processes depend on a thorough understanding of the molecular, cellular and physiologic basis of human aging, as well as the genetic and environmental factors that contribute to inter-individual differences.
This proposed training program brings together cell and molecular biologists and physiologists from the Lawrence Berkeley National Laboratory (LBNL) and the University of California Berkeley (UCB) who share contiguous and overlapping facilities in Berkeley, CA. The program offers outstanding research training in the genetic and environmental factors that influence aging rates, and in the molecular cellular and physiological causes and consequences of aging in mammals. The proposed trainers are experienced investigators with diverse but complementary research interests and experimental approaches. the training program will be enhanced by the strong biomedical research community that exists in the Berkeley/San Francisco Bay area, and the growing commitment to aging research at LBNL.
The proposed training program is for individuals holding a Ph.D. or M.D. degree, and interest in career in aging research. In addition to the research projects described herein, the trainees will attend regular seminars and research meetings that will provide them with a broad education in aging and related topics and critical feedback on their research projects. The research facilities available to trainees include the Center for Functional Imaging with its ability to produce short-lived isotopes for use in PET and MRI scans, a barrier and transgenic mouse facility, a high throughput DNA sequencing facility, the Resource for Molecular Cytogenetics with its emphasis on positional cloning and functional genomics, and extensive cell culture and molecular biology facilities.
