英文摘要
DESCRIPTON (Provided by applicant): The candidate was trained as a biochemist at UCLA where he specialized in studies of oxidative damage in yeast. Dr. Longo has spent the past three years as a PI of a funded yeast laboratory and as a Research Associate/Assistant Professor working on Alzheimer?s Disease-related projects. The candidate?s long-term career goals are to be a faculty member in a neuroscience program and to continue research on aging. He is applying for the K01 Award in Aging to develop his research skills and knowledge in the neuroscience field with particular focus on the fundamental mechanisms of oxidative damage in aging and neurodegenerative diseases. Dr. Caleb. Finch, Prof. of Gerontology, Neuroscience, and Molecular Biology at the Andrus Gerontology Center, will act as Dr. Longo?s mentor along with Prof. Kelvin Davies. The international stature of these faculty members in the field of aging, oxidative stress, and neurodegenerative diseases, make this environment ideal for the development of Dr. Longo expertise in these fields. Dr Longo will participate in the bimonthly chalk talks in the Neurobiology and Endocrinology of Aging, will attend the weekly research seminars and journal clubs in USC?s multidisciplinary neuroscience program, and will attend a course on the responsible conduct of research. The candidate will also be exposed to clinical studies on cognitive changes during normal aging and during Alzheimer disease (AD). The research project "4 Iron-4 Sulfur Clusters in Aging and Alzheimer?s Disease" proposes to test the hypothesis that the 4Fe-4S clusters, contained in certain dehydratase enzymes sensitive to superoxide toxicity, are a major source of the redox-active iron that mediates oxidative damage during aging and in Alzheimer?s Disease. This hypothesis will be tested by measuring redox-active iron in animal models for AD and by determining the contribution of 4Fe-4S clusters to the pool of redox-active iron and to oxidative damage and death in neurons and neuronal cell lines exposed to oxidants and beta amyloid.
