Metformin against Cancer Stem Cells through the Modulation of Energy Metabolism : Special Considerations on Ovarian Cancer

Abstract EN

Ovarian cancer is the most lethal gynecologic malignancy among women worldwide and is presumed to result from the presence of ovarian cancer stem cells.

To overcome the limitation of current anticancer agents, another anticancer strategy is necessary to effectively target cancer stem cells in ovarian cancer.

In many types of malignancies, including ovarian cancer, metformin, one of the most popular antidiabetic drugs, has been demonstrated to exhibit chemopreventive and anticancer efficacy with respect to incidence and overall survival rates.

Thus, the metabolic reprogramming of cancer and cancer stem cells driven by genetic alterations during carcinogenesis and cancer progression could be therapeutically targeted.

In this review, the potential efficacy and anticancer mechanisms of metformin against ovarian cancer stem cells will be discussed.
