Abstract
The content of 4 fractions of nuclear proteins (histones, acid chromatin protein, globulins and chromatin-free acid protein) in diploid and polyploid hepatocytes from intact and regenerating liver of mice is studied. These types of nuclei are found to differ in the protein content and in the protein/DNA ratio. Synthesis of all classes of nuclear proteins was intensified at the G1-stage, and synthesis of DNP non-histone proteins at the end of S- and G2-stage. Possible role of different nuclear proteins in the regulation of cell multiplication is discussed.
