In summary, we’ve got supplied evidence that insulin protects melanoma cells in the chemotherapeutic drug DTIC and BRAF inhibitors. Additionally, we have shown that insulin-induced drug resistance is mostly as a consequence of activation of the PI3K/Akt pathway. Our results indicate that combinations of inhibitors on the PI3K/Akt pathway and DTIC or BRAF inhibitors may very well be useful to improve the therapeutic efficacy within the therapy of melanoma, in distinct, in patients with obesity and type II diabetes that have elevated serum insulin levels.DisclosureThe authors report no conflicts of interest in this work.
