摘要: Cyclic AMP (cAMP) and its action by way of cAMP-dependent protein kinase is important for sperm motility. Previous studies on germ cells have demonstrated a selective decrease in the amount type I during spermatid development, that II was major form present elongating spermatids mature sperm. This would indicate activation gene haploid cells, encoding regulatory subunit kinase. However, expression such has so far not been shown. In study we demonstrate high-levelled unique mRNA species specific at late stages spermatogenesis, i.e. elongation.
