WebApr 21, 2024 · The complex genomic structure of eukaryotic cells is primarily achieved by the binding of DNA to histones. Different members of the histone families form a complex with genomic DNA and, as a nucleosome, constitute the functional unit of chromatin. In addition to their structural functionality, histones are also involved in other molecular … WebAug 8, 2024 · As a read-out, we examined the levels and the (re)positioning of γ-H2AX tags and histone H3K9me3 heterochromatin tags after immunostaining in three-dimensional (3D)-conserved cell nuclei. As model, we used HPV16 positive immortalized human keratinocytes that were cultivated under normal, folate deficient, and reconstituted …
WebApr 16, 2010 · It was reported several years ago, that in mammalian cells the phosphorylation of the subtype of histone H2A, called H2AX, in the position of Ser139 occurs in response to DSB formation. The phosphorylated form of H2AX is called H2AX [18, 19]. Since then, many researchers focused on the explanation of mechanisms which … WebFeb 8, 2005 · How phosphorylated histone H2AX, known as γ-H2AX, functions in the cellular response to DNA double-strand breaks is the subject of intensive investigation.
