Research Abstract

The gene expression is selectively controlled. The individuality of the cell is determined by combination of activated genes so that it makes the physiological functions as the entire individual. Epigenetics is taking part as one of the control mechanisms of gene expression. Recent reports showed that epigenetic control is important in embryology or oncology. In mammalian spermatogenesis, spermatogenic cells develop into functional gametes through meiosis with complex gene expression. Our study suggested that certain genes important in spermatogenesis are involved in epigenetic control of its expression.
