Abstract

The mechanism of metformin action still remains controversial, in particular on mitochondrial activity and the involvement of AMPK. Wang et al. show that pharmacological metformin concentration or dose improves mitochondrial respiration by increasing mitochondrial fission through AMPK-Mff signaling; in contrast, supra-pharmacological metformin concentrations reduce mitochondrial respiration through decreasing adenine nucleotide levels.
