Naked Mole Rat at Leibniz-IZW (IMAGE) Forschungsverbund Berlin Caption Scientists from Russia, Germany and Switzerland now confirmed a mechanism in mouse, bat and naked mole rat cells -- a 'mild depolarization' of the inner mitochondrial membrane -- that is linked to ageing: Mild depolarization regulates the creation of mitochondrial reactive oxygen species (mROS) in cells and is therefore a mechanism of the anti-ageing program.
