Fig. 3.

Effect of local or systemic PGF_2α analogue (aPGF_2α) administration on the (a) the ratio of BCL2 to BAX mRNA expression and (b) the ratio of BCL2 to BAX protein concentration levels in the early- and middle- stage corpora lutea (CL), respectively. The gray bars represent the control group, and the black bars represent local or systemic aPGF_2α administered groups. Letters ^a,b indicate statistical differences between all experimental groups in the early and middle- stage CL. Asteriks ^* indicate statistical differences between local/systemic aPGF_2α injected early CL vs local/systemic aPGF_2α injected middle-stage CL
