The expression of apoptosis-related genes in porcine COCs. The comparison of the expression of apoptosis-related genes BCL-2, BAX and BCL-2/BAX mRNA ratio in COCs derived from non-stimulated gilts with natural estrus (group I; n = 8), stimulated with PMSG/hCG (group II; n = 5) or with PMSG/hCG + PGF2α (group III; n = 7). Values from qPCR were normalized to GAPDH gene expression. Data are expressed in arbitrary units as the ls mean ± S.E.M. Different superscripts depict significant statistical differences at p < 0.05.
