[Effects of ceruloplasmin/PTEN on histone modifications induced by silica].
In Wei Sheng Yan Jiu, 2014
RESULTS: Silica could induce the high level of protein lysine acetylation and acetyl-histone H2B (lys5/12), acetyl-histone H3 (lys9/14), acetyl-histone H4 (lys12) and the low level of methyl-histone (arg2), which could be reversed by Cp, in no exception for acetyl-histone H2B (lys5/12).
Nuclear organization and transcriptional silencing in yeast.
Lausanne, Switzerland. In Experientia, 1997
Elevation of the internal nuclear pools of Sir1p, Sir3p and Sir4p can relieve the lack of repression at the LYS2 locus in an additive manner, suggesting that in wild-type cells silencer function is facilitated by its juxtaposition to a pool of highly concentrated Sir proteins, such as those created by telomere clustering.
