Enhancement of mtDNA damage removal in UVC-exposed C. elegans treated with L-theanine. (A) The increase in L3 arrest exhibited a dose-dependent relationship after repeated exposure to UVC radiation. (B) Following 48 h of UVC exposure, damage to both mitochondrial and nuclear DNA showed a dose-dependent increase after repeated UVC exposure. (C) The percentage changes in L3 arrest of UVC-exposed N2 worms treated with varying concentrations of L-theanine are illustrated. (D) Treatment with L-theanine for 48 h decreased the frequency of mitochondrial DNA damage induced by UVC exposure. (E) The administration of L-theanine did not have an impact on the L3 arrest of N2 worms. (F) Treatment with L-theanine did not result in alterations in the body length of N2 worms. Results are means ± SD (results from 3 independent experiments, * p < 0.05, ** p < 0.01).
