histones

Also found in: Dictionary, Thesaurus, Encyclopedia.

histones

Strongly alkaline proteins associated with DNA. Histones may be released into the blood and appear in the urine when tissue breaks down in wasting illnesses.

The researchers harvested satellite cells from both healthy and injured muscle tissue of young mice and from healthy tissue of old mice; extracted these cells' DNA with the histone coatings intact; and used tagged antibodies targeting the different kinds of marks to find which spots on those histones were flagged with either "stop" or "go" signals.

Scientists distinguish signatures of old versus young stem cells

So it makes sense that histone methylation is largely used to silence master genes that may be needed at multiple points during development, while DNA methylation is mostly used to switch off genes at later stages, when cells have already been tailored to specific functions, and those genes are less likely to be needed again.

How Genes Turn On and Off

Ethanol-induced alterations in SAMe levels can affect the methylation of histones or DNA, which in turn can modify gene expression, thereby contributing to liver injury (Lu and Mato 2012).

The findings are the first to illustrate crosstalk between mRNA and histone modifications, and may lead to new ways to target genes in the brain, Zhao said.

The histone H4 gene is supposed to be highly conserved among all organisms with the exception of variations found in the ciliate species.

15) Cruciferous vegetables such as kale, cabbage, brussels sprouts, and broccoli sprouts contain chemical components, such as sulforaphane (SFN) and indole-3-carbinol (I3C), which have been revealed to be regulators of microRNAs (miRNAs) and inhibitors of histone deacetylases (HDACs) and DNA methyltransferases (DNMTs).

In the mouse, histone acetylation of core histones (H3K9, H3K14, and H4K16) was rapidly deacetylated following SCNT, and reacetylation occurred after activation treatment.

Epigallocatechin-3-gallate reactivates silenced tumor suppressor genes, Cip1/p21 and p16INK4a, by reducing DNA methylation and increasing histones acetylation in human skin cancer cells.

High Expression of H3K9me3 Is a Strong Predictor of Poor Survival in Patients With Salivary Adenoid Cystic Carcinoma

G9a histone methyltransferase catalyzes H3K9 methylation in mammals because disruption of the Gga gene resulted in a drastic decrease in H3K9 methylation [24-27].
