title: [Turnover of chromatin proteins in rat liver during induction of RNA synthesis by electrostimulation of the hypothalamus].
abstract: It has been shown that the induction of D-RNA synthesis in rat liver nuclei by electrostimulation of hypothalamus is accompanied by a decrease in chromatin protein synthesis and an increase in phosphorylation and acetylation of chromatin proteins. The decrease of the histone synthesis is mainly due to the decrease of [14C]lysine and [14C]alanine incorporation into histones H1 and H4. The relationship between H1, H2b-H3, H2a and H4 histone fractions remains unchanged. Electrostimulation of hypothalamus increases acetylation of H2a and H4 histone fractions and phosphorylation of all histones with the exception of histone H1.
