Abstract |
Metformin has been a first-line treatment for type II diabetes mellitus for decades and is the most widely prescribed antidiabetic drug. Retrospective studies have found that metformin treatment is associated with both reduced cancer diagnoses and cancer-related deaths. Despite the prevalence of metformin use in the clinic, its molecular mechanism of action remains controversial. In a recent issue of Cancer & Metabolism, Andrzejewski et al. present evidence that metformin acts directly on mitochondria to inhibit complex I and limits the ability of cancer cells to cope with energetic stress. Here, we discuss evidence that supports the role of metformin as a cancer therapeutic.
