摘要
We explored the mechanism of antigrowth action of Curcumin by investigating its effect on epidermal growth factor (EGF) receptor intrinsic kinase activity in the human epidermoid carcinoma A431 cells. The short-term treatment of cells with Curcumin inhibited EGF receptor intrinsic kinase activity up to 90% in a dose- and time-dependent manner, and also inhibited EGF-induced tyrosine phosphorylation of EGF receptors. The observed early effects of Curcumin were mediated via a cellular mechanism(s), and preceded the period when inhibition of cell growth occurred.
