Investigation of geroprotective and radioprotective effects of berberine and trichostatin A on the model of Drosophila melanogaster

The search for drugs that slow down the rate of aging and stimulate radioresistance is an urgent task of biology, ecology, and medicine. In this work we have studied the effects of trichostatin A and berberine on the lifespan, resistance to the paraquat prooxidant and acute gamma irradiation of the Drosophila melanogaster fruit fly. Trichostatin A demonstrated a better geroprotective effect, increasing the Drosophila lifespan by 3-9 %. However, an increase in radioresistance was observed only after the application of berberine in males. Their median survival after gamma irradiation increased by 25 %. Trichostatin A, on the contrary, increased the sensitivity of flies to gamma irradiation genotoxic effects, reducing the survival by 7-17 %.
