Abstract
As the information in the existing literature regarding the epigenetic modifications occurring in the advanced stages of spermatogenesis of crested newt is still scarce, we have investigated the effect of a Histone Deacetylase (HDAC) inhibitor, Trichostatin A (TSA), at the cytological level (by transmission electron microscopy - TEM, immunohistochemistry technique, fluorescence microscopy) and at the molecular level (AUT-PAGE and ChIP assay) on Triturus cristatus spermatogenesis. Our results have revealed an important role for regulation of histone deacetylase activity in controlling histone hyperacetylation and the replacement with sperm nuclear basic proteins during spermiogenesis.
