Abstract
Oogenesis is a critical event in the formation of female gamete, whose role in development is to transfer genomic information to the next generation. During this process, the gene expression pattern changes dramatically concomitant with genome remodelling, while genomic information is stably maintained. The aim of the present study was to investigate the presence of H4 acetylation of the oocyte and somatic 5S rRNA genes in Triturus cristatus, using chromatin immunoprecipitation assay (ChIP). Our findings suggest that some epigenetic mechanisms such as histone acetylation could be involved in the transcriptional regulation of 5S rRNA gene families.
