Figure 1. Induction of γ-H2AX foci in GV oocytes following MG and resveratrol (RSVL) treatment.
Oocytes were blocked at the GV stage in M2 medium plus 2.5 µM milrinone and were cultured with or without 75 µM MG and different concentration of resveratrol for 6 h. DNA and γ-H2AX were stained and the results show that resveratrol can effectively protect MG-induced the formation of γ-H2AX, the protein marker of DSB. (A) Representative samples of control GV-stage oocytes with γ-H2AX 0–5 foci, >5–10 foci and >10 foci. Red, γ-H2AX; Blue, DNA. Scale bar = 20 µm. (B) The proportion of GV oocytes with γ-H2AX >10 foci after MG and different concentration of resveratrol treatment (5, 10 and 25 µM). Data are mean ± SEM of three independent experiments. Different letters denote statistically significant differences (P<0.05).
