Evaluation of ROS content in blastocysts: A, representative photographs of ROS levels in mouse embryos after staining with DCHFDA; B, Fluorescence intensity was quantified by Image J. Data are expressed as a mean value ± SEM of three independent experiments. Different letters in the same picture mean the significant difference between the treatments (P < 0.05).
Fig. 2.
The expression of PPARγ and Nrf2 in cultured mouse embryos, which were exposed to H2O2 of 30 min and then treated with pioglitazone, with untreated embryos as a control. A, PCR results of PPARγ and Nrf2 RNA in mouse embryos; B, relative expression of PPARγ and Nrf2 RNA normalized with the internal marker GAPDH. Different letters in the same picture mean the significant difference between the treatments (P < 0.05).

The expression of GPX and SOD in cultured mouse embryos, which were exposed to H2O2 of 30 min and then treated with pioglitazone, with untreated embryos as a control. A, PCR results of GPX and SOD RNA in mouse embryos; B, Relative expression of GPX and SOD RNA normalized with the internal marker GAPDH. Different letters in the same picture mean the significant difference between the treatments (P < 0.05).
Fig. 4.
The expression of NADPH oxidase in cultured mouse embryos, which were exposed to H2O2 of 30 min and then treated with pioglitazone, with untreated embryos as a control. A, PCR results of NADPH oxidase RNA in mouse embryos; B, relative expression of NADPH oxidase RNA normalized with the internal marker GAPDH. Different letters in the same picture mean the significant difference between the treatments (P < 0.05).
