Fig. 1From: Low oxygen tension increases mitochondrial membrane potential and enhances expression of antioxidant genes and implantation protein of mouse blastocyst cultured in vitroThe transcription levels of antioxidant enzymes (MnSOD and PRDX5) and HIF target genes (VEGF and GLUT-3) significantly increased in 3% O2 than 20% O2 . Results detected by RT-qPCR were mean ± SE calculated by the ΔΔCt method, normalized to β-actin. Means with different superscripts were significantly different (*P < 0.05, **P < 0.0001)Back to article page
