The potential role of metformin in treating endometrial cancer remains to be explored. The current study investigated the role of metformin in 17?-estradiol-induced epithelial-mesenchymal transition (EMT) in endometrial adenocarcinoma cells. We found that 17?-estradiol promoted proliferation and migration, attenuated apoptosis in both estrogen receptor (ER) positive and ER negative endometrial adenocarcinoma cells (Ishikawa and KLE cells, respectively). Metformin abolished 17?-estradiol-induced cell proliferation and reversed 17?-estradiol-induced EMT in Ishikawa cells. In addition, metformin increased the expression of ?Klotho, a fibroblast growth factors (FGFs) coreceptor, and decreased ERK1/2 phosphorylation in both Ishikawa and KLE cells. Decreased expression of ?Klotho was noted in human endometrial adenocarcinomas, and plasmid-driven expression of ?Klotho in Ishikawa cells abolished 17?-estradiol-induced EMT via inhibiting ERK1/2 signaling. ?Klotho expression and metformin show synergetic effects on the proliferation and the EMT in Ishikawa cells. Furthermore, we demonstrated that the anti-EMT effects of metformin could be partly abolished by introducing Compound C, a specific AMPK? signaling inhibitor. In conclusion, metformin abolishes 17?-estradiol-induced cell proliferation and EMT in endometrial adenocarcinoma cells by upregulating ?Klotho expression, inhibiting ERK1/2 signaling, and activating AMPK? signaling. Our study provides novel mechanistic insight into the anti-tumor effects of metformin.
