Rapid alterations in initiation rate and recruitment of inactive RNA are temporally correlated with S6 phosphorylation.


HeLa cells propagated in spinner culture for 3-4 days without replenishing medium or serum progressively decrease the amount of mRNA and rRNA in polysomes, as well as the elongation rate. Treatment of these cells with low doses of cycloheximide shifts at least two thirds of the subpolysomal ribosomal particles into polysomes, indicating that the rate of… (More)
