Figure 5. Effect of melatonin on the expression of antioxidant and apoptosis related genes during the development of EB1-exposed embryos. (A–F) relative expression levels of Sod1, Gpx4, Cat, Bcl2l1, Bax and Caspase3, respectively. CON, the control group. EB1, embryos treated with EB1. MT, embryos treated with melatonin. ME, embryos treated with both melatonin and EB1. a-dValues for a given group in columns with different superscripts differ significantly (p < 0.05).
