[Role of DNA repair genes in radiation-induced changes of lifespan of Drosophila melanogaster].

One of the main effects of various stress factors, including ionizing radiation, is DNA damage. Accumulation of DNA damage and somatic mutations in the somatic tissues is regarded as one of the basic mechanisms of aging. We have developed an approach to the study of molecular and genetic mechanisms of radioadaptation, which is based on the analysis of changes in the lifespan of Drosophila with a transformed genotype.
