Metformin Suppresses Ovarian Cancer Growth and Metastasis with Enhancement of Cisplatin Cytotoxicity In Vivo
Open accessAbstract
Ovarian cancer is the most lethal gynecologic cancer in women. Its high mortality rate (68%) reflects the fact that 75% of patients have extensive (>stage III) disease at diagnosis and also the limited efficacy of currently available therapies. Consequently, there is clearly a great need to develop improved upfront and salvage therapies for ovarian cancer. Here, we investigated the efficacy of metformin alone and in combination with cisplatin in vivo. A2780 ovarian cancer cells were injected intraperitoneally in nude mice; A2780-induced tumors in nude mice, when treated with metformin in drinking water, resulted in a significant reduction of tumor growth, accompanied by inhibition of tumor cell proliferation (as assessed by immunohistochemical staining of Ki-67, Cyclin D1) as well as decreased live tumor size and mitotic cell count. Metformin-induced activation of AMPK/mTOR pathway was accompanied by decreased microvessel density and vascular endothelial growth factor expression. More importantly, metformin treatment inhibited the growth of metastatic nodules in the lung and significantly potentiated cisplatin-induced cytotoxicity resulting in approximately 90% reduction in tumor growth compared with treatment by either of the drugs alone. Collectively, our data show for the first time that, in addition to inhibiting tumor cell proliferation, metformin treatment inhibits both angiogenesis and metastatic spread of ovarian cancer. Overall, our study provides a strong rationale for use of metformin in ovarian cancer treatment.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
