NUCLEAR PROTEIN IN THE LIVER IN PROTEIN-CALORIE DEFICIENCY.
1. The effect of protein-calorie deficiency on nuclear proteins was studied in growing and adult rats by using chemical and electrophoretic methods of fractionation. 2. After 7 days on protein-deficient diets, the amount of neutral-soluble proteins increased, and their electrophoretic pattern changed, with the appearance of a new component. 3. The histone fraction of the liver nuclei in rapidly growing rats was lower than that in either deficient or adult animals. 4. The possible role of nuclear proteins in relation to synthesis of the proteins and nucleic acids of the other parts of the cells is discussed.
