1 Metformin sensitizes human bladder cancer cells to TRAIL-induced apoptosis through mTOR/S6K1-mediated downregulation of c-FLIP. Metformin ribosomal protein S6 kinase B1 Homo sapiens
2 However, metformin inhibited the mTOR/S6K1 pathway in 253J and RT4 cells, which usually regulates protein translation; moreover, knockdown of S6K1 effectively reduced the levels of c-FLIPL, indicating that metformin downregulates c-FLIP through inhibition of the mTOR/S6K1 pathway.

6 However, metformin inhibited the mTOR/S6K1 pathway in 253J and RT4 cells, which usually regulates protein translation; moreover, knockdown of S6K1 effectively reduced the levels of c-FLIPL, indicating that metformin downregulates c-FLIP through inhibition of the mTOR/S6K1 pathway. Metformin ribosomal protein S6 kinase B1 Homo sapiens
7 Taken together, our results indicate that metformin sensitizes human bladder cancer cells to TRAIL-induced apoptosis through downregulation of c-FLIP, which is mediated by the mTOR/S6K1 pathway, but independent of AMPK; furthermore, these findings provide a rationale for the combined application of metformin with TRAIL in the treatment of bladder cancer.
