The effect of PI-3-kinase and mTOR inhibitors on insulin and EGF signal transduction pathway in HC11 cells. HC11 cells were serum starved overnight in the absence of insulin and the next day the cells were incubated four hours with LY294002 (5 μM) or Rapamycin (25 nM) prior to re-stimulation with insulin (5 μg/ml) or EGF (100 ng/ml) for times indicated. Lysates were harvested and analyzed by western blotting using antibodies specific for phosphorylated and non-phosphorylated forms of the indicated proteins.
