[Change in RNase activity in rat liver cells in cycloheximide protein synthesis inhibition].
Administration of cycloheximide to rats does not change the activity of acid and alkaline RNAases in the cytoplasm of hepatocytes. At the same time cycloheximide-induced inhibition of protein synthesis leads to a fall in the activity of RNAase of microsomes and membrane-bound polyribosomes. The activity of RNAase of free polyribosomes of hepatocytes rises considerably under the action of cycloheximide.
