Cleaved caspase-3, -6, and -7 expression in rat endometrium during estrous cycle. Polyoestrus rats were sacrificed at each stage of the estrous cycle (diestrus, proestrus, estrus and metestrus) and total endometrial proteins were collected. A) Western blots of cleaved caspase-3, -6 and -7 (one blot presented out of 4). Graphics shows Western blots densitometric analysis. Data represent the mean ± SEM of four independent experiments (four different rats). B) Immunohistochemistry of cleaved caspase-3. IHC shown are from one representative experiment (a total of four different uterine sections from four different rats per day of the estrous cycle have been tested). *Significantly different from diestrus and proestrus (p < 0.05).
