Fig. 2From: SIRT1-dependent modulation of methylation and acetylation of histone H3 on lysine 9 (H3K9) in the zygotic pronuclei improves porcine embryo developmentThe effect of resveratrol on H3K9 methylation and acetylation in zygotic pronuclei. a Fluorescent signal intensities relative to signal intensity of vehicle control (= 1) and b representative images of H3K9me3 and H3K9ac in both pronuclei. a,b,c;1,2,3Significant differences in H3K9me3 and H3K9ac, respectively, among experimental groups (P ≤ 0.05).
