background: although aberrant protamine (prm) ratios have been observed in infertile men, the mechanisms that implicit the uncoupling of prm1 and prm2 expression remain unclear. to uncover these mechanisms, in this observational study we have compared the prm1/prm2 mrna ratio and mrna contents of two regulatory factors of these genes. materials and methods: in this experimental study, sampling ...

background: some dynamic changes occurs during spermatogenesis such as histone removal and its replacement with transition nuclear protein and protamine. these proteins are required for packing and condensation of sperm chromatin. jhdm2a is a histone demethylase that directly binds to promoter regions of tnp1 and prm1 genes and controls their expression by removing h3k9 at their promoters.objec...

The lysine demethylase 3A (KDM3A, JMJD1A or JHDM2A) controls transcriptional networks in a variety of biological processes such as spermatogenesis, metabolism, stem cell activity, and tumor progression. We matched transcriptomic and ChIP-Seq profiles to decipher a genome-wide regulatory network of epigenetic control by KDM3A in prostate cancer cells. ChIP-Seq experiments monitoring histone 3 ly...

Histone lysine (K) residues, which are modified by methyl- and acetyl-transferases, diversely regulate RNA synthesis. Unlike the ubiquitously activating effect of histone K acetylation, the effects of histone K methylation vary with the number of methyl groups added and with the position of these groups in the histone tails. Histone K demethylases (KDMs) counteract the activity of methyl-transf...
