Such a decrease seems to be due, at least in part, to a reduction in transcript stability, since the IR mRNA half-life was observed to decline from approximately 4 h in untreated cells to 3 h in epinephrine-treated cells. Computer inspection of the sequence of the 3′ untranslated region of the human IR mRNA showed nine AUUUA pentamers and three U-rich regions. These domains could be targets for a RNA-binding protein induced by treatment with epinephrine producing a destabilization of IR mRNA in U-937 cells. 439-4286 https://hdl.handle.net/20.500.11984/14596 Insulin Receptor Gene Expression Epinephrine U-937 Human Promonocytic Cells Insulin Receptor Isotypes Epinephrine-Induced Reduction in Insulin Receptor mRNA Level and Stability in U-937 Human Promonocytic Cells
