title: Histone H2A variant synthesis in aging human diploid cells.
abstract: The synthesis of the various classes of core particle histones was determined in human diploid fibroblast-like cells of different in vitro ages as they were stimulated to enter the cell cycle. Histone H2A synthesis in older populations was lower during G1 but was similar to younger cells at G0/G1 and S phases. The reduced synthesis during G1 was primarily the result of a decline in the synthesis of the H2A.1/.2 component.
