Effects of ionizing radiation at with differently active transposons.

The role of transposable elements in formation of radiobiological effects is understudied and contradictory. The aim of this study was to investigate the response of to irradiation depending on the level of activity transposons and the role of transposons in formation of ionizing radiation late effects. The individuals of with different level activity of -elements were exposed to acute irradiation in doses of 1-100 Gy at early ontogenesis stages. The reaction of individuals to exposure was studied using the larvae survival rate, morphological parameters of reproduction system, DNA damage rate, and mutability of locus. We found the pronounced linear deferred effects of irradiation for animals with a high activity level of full-size copies. The radiosensitivity of individuals with a mean level of activity transposon was whether higher or did not differ from the radiosensitivity of animals with a low activity . The obtained results suggest that full-size -elements with a high activity level (less often with a mean activity level) are responsible for delayed deleterious irradiation effects.
