Witryna15 lut 2012 · The chromatin state of imprinted regions was found to closely resemble heterochromatin and may be distinct from the general developmental silencing of genes, as H3K27 trimethylation was not present at all imprinted genes. The enrichment of H3K4, H3K9, and H4K20 trimethylation was present in imprinted genes regardless of … Witryna10 kwi 2024 · ATRX loss produces chromatin decompaction at telomeres and repetitive elements [44,45,46]. ATRX deficiency causes severe chromosomal cohesion and congression abnormalities in Hela cells . ATRX regulates the expression of certain imprinted genes in the brain by modifying the formation of chromatin loops and …
