Metformin enhanced in vitro radiosensitivity associates with G2/M cell cycle arrest and elevated adenosine-5’-monophosphate-activated protein kinase levels in glioblastoma

Abstract

It is hypothesized that metabolism plays a strong role in cancer cell regulation. We have recently demonstrated improved progression-free survival in patients with glioblastoma who received metformin as an antidiabetic substance during chemoradiation. Although metformin is well-established in clinical use the influence of metformin in glioblastoma is far from being understood especially in combination with other treatment modalities such as radiation and temozolomide.
