(ADP-ribosyl)ation pattern of chromosomal proteins during ageing

Abstract:
(ADP-ribosyl)ation of chromosomal proteins was studied by incubating the nuclei of brain and liver of young and old rats with 14C-NAD+. In brain as well as in liver histone proteins show approximately 2-3 fold higher (ADP-ribosyl)ation than that of non-histone chromosomal (NHC) proteins of both the age groups. H1 seems to be the major target for (ADP-ribosyl)ation. Amongst nucleosomal histones H2B is the main acceptor of 14C-labelled ADP-ribose moieties. A sharp age related decline of (ADP-ribosyl)ation of chromosomal proteins was observed in both the tissues.
