Single bout of exercise has a capability to increase the generation of free radicals but regular exercise evoked adaptation decreases the accumulation of oxidative damage. We are interested in the molecular processes by which regular exercise increases mean life-span, especially on those which are related to oxidative challenge. Our data revealed that exercise induces the activity of some DNA repair enzymes especially in the nucleus. We also reported that the regulation of mitochondrial base excision repair appears to be different from nuclear ones. Since exercise has a systemic effect on the body, we are monitoring the molecular adaptation in different organs, including brain, spinal cord, liver, heart and skeletal muscle. Our earlier result showed that regular exercise is able to attenuate the deleterious effects of aging on brain, by decreasing the accumulation of oxidative damage and by the induction of housekeeping enzymes. We have also reported that age-associated increase of the DNA binding of NF-kB in the liver and the beneficial effects of exercise through redox regulation. The role of sirtuins in aging process and the possible effects of exercise on these proteins are very intriguing. Currently, we are interested in how sirtuins mediated histone deacetylation modified by exercise training and the impact on cell, organ and system aging. Our laboratory has collaboration with American, Japanese, Chinese, Greek, Indian, Holland, Canadian, South-Korean, Finn, French and British institutions which includes visits of researchers, exchange of samples and publishing joint papers.
