Dynamically acetylated histones of chicken erythrocytes are selectively methylated.
The relationship between histone acetylation and methylation in chicken immature erythrocytes was investigated. Previous studies have shown that transcriptionally active/competent gene-enriched chromatin fragments are enriched in newly methylated histones H3 and H4. Moreover, newly methylated histone H4 is hyperacetylated. Here, we show that dynamically acetylated histone H4 is selectively enga...
متن کاملMethylated basic amino acid composition of histones from the various organs from the rat.
Newborn rats received 5 muCi each of [3H]lysine and [methyl-14C]methionine/g body weight. They were killed 10 days later and the nuclei prepared from the kidneys, liver, cerebrum, cerebellum, and thymus. The five major histones were extracted from these nuclei by the method of Johns and further purified on Bio-Gel P-10. The histones were hydrolyzed and the basic amino acids fractionated on Beck...
متن کاملTrxG and PcG Proteins but Not Methylated Histones Remain Associated with DNA through Replication
Propagation of gene-expression patterns through the cell cycle requires the existence of an epigenetic mark that re-establishes the chromatin architecture of the parental cell in the daughter cells. We devised assays to determine which potential epigenetic marks associate with epigenetic maintenance elements during DNA replication in Drosophila embryos. Histone H3 trimethylated at lysines 4 or ...

متن کاملReduced levels of histones H1o and H1b, and unaltered content of methylated DNA in rainbow trout hepatocellular carcinoma chromatin.
The levels of histone subtypes and DNA methylation of aflatoxin-induced rainbow trout hepatocellular carcinoma and adult liver nuclei were compared. The hepatocellular carcinoma nuclei were enriched in the ubiquitinated species of histone H2A and depleted in histones H1o and H1b. The 5-methylcytosine content and methylation patterns of the vitellogenin genes and the transcriptionally inactive T...
