Metformin Inhibits Growth of Thyroid Carcinoma Cells, Suppresses Self-Renewal of Derived Cancer Stem Cells, and Potentiates the Effect of Chemotherapeutic Agents

Abstract

Metformin markedly diminished growth stimulation by insulin and showed an additive antimitogenic effect to chemotherapeutics agents. Therefore, our results suggest this drug as adjuvant treatment for thyroid cancer in type 2 diabetic patients.
