Loss of histone variant macroH2A2 expression associates with progression of anal neoplasm
AIMS The macroH2A histone variants are epigenetic marks for inactivated chromatin. In this study, we examined the expression of macroH2A2 in anal neoplasm from anal intraepithelial neoplasia (AIN) to anal squamous cell carcinoma (SCC). METHODS AIN and anal SCC samples were analysed for macroH2A2 expression, HIV and human papilloma virus (HPV). The association of macroH2A2 expression with clin...
متن کاملA System for Genome-Wide Histone Variant Dynamics In ES Cells Reveals Dynamic MacroH2A2 Replacement at Promoters
Dynamic exchange of a subset of nucleosomes in vivo plays important roles in epigenetic inheritance of chromatin states, chromatin insulator function, chromosome folding, and the maintenance of the pluripotent state of embryonic stem cells. Here, we extend a pulse-chase strategy for carrying out genome-wide measurements of histone dynamics to several histone variants in murine embryonic stem ce...
متن کاملHistone H2A variants and the inactive X chromosome: identification of a second macroH2A variant.
MacroH2A1 is an unusual variant of the core histone H2A which is enriched in chromatin on the inactive X chromosome of female mammals. The N-terminal third of the protein shares 65% amino acid identity with core histone H2A, while the remaining two-thirds of the protein are novel, with a small stretch of basic amino acids and a putative leucine zipper motif. We have now cloned a second macroH2A...
متن کاملP-217: Expression Analysis of The Histone Variant H2A.Z in Endometrium Tissue during The Menstrual Cycle
Background: The human endometrium undergoes cyclical changes including proliferation, differentiation, tissue breakdown and shedding (menstruation) throughout a woman’s reproductive life. The postovulatory rise in ovarian progestrone induces profound remodeling in chromatin structure of cells, and consequently differentiation of estradiol-primed endometrium. This change is crucial for embryo im...
متن کاملA new fluorescence resonance energy transfer approach demonstrates that the histone variant H2AZ stabilizes the histone octamer within the nucleosome.
Nucleosomes are highly dynamic macromolecular complexes that are assembled and disassembled in a modular fashion. One important way in which this dynamic process can be modulated is by the replacement of major histones with their variants, thereby affecting nucleosome structure and function. Here we use fluorescence resonance energy transfer between fluorophores attached to various defined loca...
