Research Abstract |
In this study, we investigated the effects of oxidative stress on DNA methylation and the expression of active DNA demethylation related genes. The results of this study showed that paraquat-induced oxidative stress increased the expression of Aid, which is DNA demethylation related gene. Furthermore, over-expression of Aid increased some genes expression. Taken together, these results may suggest that the oxidative stress-induced activation of Aid is involved in those genes activation through the DNA demethylation. Further analysis of promoter methylation of Aid-activated genes will help to understand the effect of oxidative stress on DNA methylation.
