From: Effects of cadmium on oxidative stress and cell apoptosis in Drosophila melanogaster larvae
DNA damage in the midgut cells of Drosophila third instar larvae under Cd stress. (A) Comet images of midgut cells in third instar larvae indicated the DNA “smearing” phenomenon of Drosophila larvae was serious with the increase of Cd concentration. (B) Tail DNA% of comet at increasing Cd concentration. (C) Tail length of comet at increasing Cd concentration. The increase of tail DNA% and tail length of comet indicating clear DNA damage in treatment groups (2.25 mg/kg, 4.5 mg/kg, 9 mg/kg). (Mean ± SD, n = 3, 50 larvae per sample, *P < 0.05, **P < 0.01, ns = not significant).
