pubmed-article:7683660 | pubmed:abstractText | Insulin induces the serine phosphorylation of the nucleolar protein nucleolin at subnanomolar concentrations in differentiated 3T3-442A cells. The stimulation is biphasic with phosphorylation reaching a maximum at 10 pM insulin and then declining to only 40% of basal levels at insulin concentrations of 1 microM. These changes are rapid, reaching half-maximal after 4 min and maximal after 15 min of incubation. The cell-permeable casein kinase II inhibitor 5,6-dichlorobenzimidazole-riboside prevents the insulin-stimulated phosphorylation of nucleolin suggesting that casein kinase II may mediate this effect of the hormone. Insulin-like growth factor 1 mimics the action of insulin on dephosphorylation of nucleolin at nanomolar concentrations suggesting that the latter effect may be mediated by insulin-like growth factor 1 receptors. Insulin treatment of 3T3-442A cells also results in a stimulation of RNA efflux from isolated, intact cell nuclei. The dose dependence of insulin-induced nucleolin phosphorylation and insulin-stimulated RNA efflux from intact cell nuclei are almost identical. Insulin induces an increase in the RNA efflux at subnanomolar concentrations in 3T3-442A adipocytes, while high (micromolar) concentrations of insulin inhibited the efflux of RNA. These data indicate that insulin regulates the phosphorylation/dephosphorylation of nucleolin, possibly via stimulation of casein kinase II, and this may play a role in regulation of the RNA efflux from nuclei. | lld:pubmed |
