Cell death is most frequently the result of apoptosis, an event that is often controlled by mitochondrial membrane permeabilization (MMP). Recent data reveal unexpected functional links between apoptosis and autophagic cell death, in the sense that MMP can trigger autophagy of damaged mitochondria. Conversely, one of the major signal-transducing molecules involved in the activation of autophagy during apoptosis – the so-called DAP kinase – can induce cell death through MMP. Connections are also emerging between apoptosis, autophagy, replicative senescence and cancer-specific metabolic changes.
