title: [Effect of insulin on RNA biosynthesis in the chromatin fractions of the liver of rats of different age].
abstract: Experiments were conducted on rats; a study was made of the age changes of insulin action on the genetic apparatus of hepatocytes. Adult (6-8-month-old) rats showed the greatest elevation of transcribing capacity of the repressed chromatin fraction 2 hours after the hormone administration, no changes occurred in the active chromatin fraction. The maximum increase of the labeled precursor inclusion in old (24--26-month-old) rats was seen 3 hours after insulin injection both in repressed and active chromatin.
