Research Interests

A major focus of the studies conducted in this laboratory is on the role of environmental factors in the etiologies of the various forms of diabetes mellitus.  Present work is centered on the mechanisms by which xenobiotics can interact with insulin producing pancreatic beta cells to either kill these cells directly, to elicit an inflammatory response against these cells which results in their destruction, or to cause their functional impairment. Currently, new molecular biological technology is being employed to study the damage and repair in specific sequences of both nuclear and mitochondrial DNA. Of particular interest is how specific lesions are repaired and what are some of the factors that may prevent this repair and cause alterations in DNA which ultimately may produce diabetes mellitus.  

A second area of interest is in the normal process of aging. This work is designed to test the hypothesis that it is the accumulation of damage within DNA that causes some of the phenotypes associated with aging. Specifically, the objective of this work is to determine how DNA repair mechanisms change with aging.  Repair in both the nucleus and the mitochondria is being evaluated in cells from individuals of differing age, in cells aged in tissue culture and in cells from individuals with genetic syndromes of premature aging. When successfully completed this work should provide new insights into how the natural process of aging can be slowed or how the consequences of its various manifestations can be lessened.
