DNA Methylation Mediates Sperm Quality via and Regulation in Japanese Flounder ().

DNA methylation is an important way to regulate gene expression in eukaryotes. In order to reveal the role of DNA methylation in the regulation of germ cell-specific gene expression during spermatogenesis of Japanese flounder (), the expression profiles of () and () genes in the gonads of female, male, and sex-reversed pseudo-male were analyzed, and the dynamic of DNA methylation was investigated. As a result, and genes were highly expressed in the testis of both male and pseudo-male , with significant variation among male individuals.
