Landschutz ascites tumour cells were incubated with different concentrations of amino acids and the labelling of RNA and proteins of ribosomal subunits was studied. 1. 1. When the cells were incubated without added amino acids, protein synthesis was

The amount of 64- and 45-S ribosomal subunits in the cytoplasm of Landschutz ascites cells has been measured under different growth conditions which produce large changes in the proportion of ribosomes as 80-S monomers and polysomes. 1. 1. In cells g

The action of insulin on the labeling of nuclear RNA of liver of diabetic rats has been examined using columns of kieselguhr coated with methylated albumin. The nuclear RNA was fractionated into a ribosomal fraction (Q1 RNA) and two DNA-like RNA frac

1. Incorporation of [14C]leucine into protein in rat liver slices, incubated in vitro, increased as the concentration of unlabelled amino acids in the incubation medium was raised. A plateau of incorporation was reached when the amino acid concentrat

The effect of chronic diabetes and treatment of rats with insulin on the protein synthetic activity of purified rat liver ribosomes was investigated in a cell-free system. 1. 1. The total ribosome population was somewhat inhibited in incorporating ac

1. The liver ribosomes of rats given cycloheximide by intraperitoneal injection incorporate less amino acid into protein than ribosomes from control rat liver when they are incubated in vitro with excess of Sephadex-treated cell sap. The effect is ra

Insulin and glucagon stimulate the activity of tyrosine transaminase of rat liver but, under our conditions, do not alter the effect of hydrocortisone on this enzyme. Neither insulin nor glucagon affects the activity of tryptophan pyrrolase when give

The case for believing that growth hormone exerts its protein anabolic action by stimulating messenger RNA synthesis is summarized. Ribosomes, but not polysomes, from liver of rats have amino acid incorporating abilities in vitro which are directly r

A method of separating proteins on Sephadex G-50 has been used to study the synthesis of proteins in the islets of Langerhans of the rat. 1. 1. The incorporation of radioactive leucine and phenylalanine into the proinsulin fraction rises when the con
