WebApr 28, 2016 · The dynamic distribution of histones H2A and H4 and phosphorylated H2A and H4 at serine 1 (HS1ph) was explored in mammalian and Decapoda germ cells, with a special focus on the distribution of H2A, H4 and HS1ph between mouse condensed spermatozoa chromatin and crab non-condensed spermatozoa chromatin. The … WebApr 13, 2024 · Given that histone acetylation is an activating histone mark associated with open chromatin and transcriptional activation , our data suggest that I-BET151 reduced levels of accessible chromatin in FLSs, and hence suppressed transcription. This is further supported by our own ATAC-seq data sets from murine MSU-primed FLSs.
