Age-related changes of the pattern of non-histone chromatin proteins from rat and mouse liver chromatin. 1979

Z A Medvedev, and M N Medvedeva, and L Robson

The non-histone chromatin (NHC) proteins which are loosely bound to DNA were extracted from young and old mouse and rat liver chromatin by 0.35 M NaCl and fractionated into three groups: water-soluble, 0.14 M NaCl soluble and 0.35 M NaCl soluble. NHC proteins in each fraction were separated by SDS-disc polyacrylamide gel electrophoresis. Special attempts were made to locate minor high-molecular-weight proteins which develop faint bands. It was found that the aging of liver cells is associated with increase in number and quantities of high-molecular-weight NHC proteins in the water-soluble group. Salt-soluble groups of NHC proteins show fewer changes of pattern.

UI	MeSH Term	Description	Entries
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008297	Male		Males
D002843	Chromatin	The material of CHROMOSOMES. It is a complex of DNA; HISTONES; and nonhistone proteins (CHROMOSOMAL PROTEINS, NON-HISTONE) found within the nucleus of a cell.	Chromatins
D002868	Chromosomal Proteins, Non-Histone	Nucleoproteins, which in contrast to HISTONES, are acid insoluble. They are involved in chromosomal functions; e.g. they bind selectively to DNA, stimulate transcription resulting in tissue-specific RNA synthesis and undergo specific changes in response to various hormones or phytomitogens.
