描述 | NT157 treatment resulted in dose-dependent inhibition of IGF1R activation, suppression of IRS protein expression, inhibition of IGF1-induced AKT activation, but increased ERK activation in NT157-treated cells in vitro. These effects were correlated with decreased proliferation and increasing apoptosis of LNCaP cells and increasing G2-M arrest in PC3 cells. NT157 can mediate suppression of IGF1R-mediated survival signaling through the established mechanism for negative feedback of IGF1R signaling: targeting IRS1/2 for serine phosphorylation and subsequent degradation. NT157 displayed little to no effect on the survival of normal melanocytes and fibroblasts. |
