Elamaran [23] used a quantitative RT-PCR assay to analyze the effects of O2 concentration (5% vs. 20%) on the relative abundance of gene transcripts in buffalo embryos produced in vitro and noted an increased expression of anti-apoptotic genes BCL-2 and MCL-1 and a decrease in the expression of pro-apoptotic genes BAX and BID in pre-implantation stage if culturing under 5% oxygen concentration.
