Title: Metabolism of 18S rRNA in rat liver cells in different functional states of protein-synthesizing apparatus

Journal Article · · Biochemistry (Engl. Transl.); (United States)
OSTI ID:5933074

The ratio of the absolute radioactivities of 28S and 18S RNAs in the fractions of membrane-bound and free polysomes and the fraction of free rat liver ribosomes was studied under conditions of inhibition of translation by cycloheximide, insulin, and cAMP. It was found that insulin and cAMP, in contrast to cycloheximide, do not induce selective degradation of 18S rRNA. The results are discussed from the standpoint of the possible role of the phosphorylation of protein S6 in the degradation of the 40S ribosomal subunit.
