Abstract:

The aim of this study was to investigate the relationship of ROS, developmental block and pioglitazone as an antioxidant. The experiment was divided into 3 groups:Control group, H2O2 group and H2O2+PIO group. The oxidative damage model of mouse embryos induced by H2O2 was established and treated with or without pioglitazone. The ROS level after treatment with pioglitazone was measured by DCHF-DA and the expression of maternal effect genes and zygotic genes were analyzed by Semi-quantitative reverse transcription PCR. The results showed that: (1) the ROS level of H2O2group was significantly higher than control group and H2O2+PIO group in both 1-cell and 2-cell embryos (P<0.05); (2) the rate of 2-cell to 4-cell transition in H2O2 group was significantly lower than control group and H2O2+PIO group (P<0.05), while the difference of 1-cell to 2-cell transition rate among the groups was not significant (P>0.05);(3) the expression of maternal effect genes (Hsf1,Zfp3612,Zp3) and zygotic genes (Eif1-α,Muerv-L,Zscan4d) in H2O2 group was lower than control group and H2O2+PIO group (P<0.05). The results provided a clear molecular aspect regarding the mechanism by which pioglitazone promoted embryos development and overcome 2-cell block.
