[Acetylation of histone and acid proteins of rat liver cells chromatin complex in postnatal ontogenesis].
No significant differences in acetylation of acid proteins was found in 1, 3- and 12-month animals in the process of postnatal development, but in old rats this process is noticeably intensified. The acetate label incorporation into histones H2 and H3 does not vary essentially in impuberal and young animals but intensifies in adult and old animals. A gradual intensification of acetylation during the whole postnatal development is registered for lysin-rich histones Hla and Hlb. The old animals differ by the highest level of acetate label incorporation into all studied fractions of chromatin proteins.
