Metformin is a potent inhibitor of endometrial cancer cell proliferation—implications for a novel treatment strategy

Conclusions We find that metformin is a potent inhibitor of cell proliferation in endometrial cancer cell lines. This effect is partially mediated through AMPK activation and subsequent inhibition of the mTOR pathway. This work should provide the scientific foundation for future investigation of metformin as a strategy for endometrial cancer prevention and treatment.
