Survival activating factor enhancement

Survivor Activating Factor Enhancement (SAFE) is a metabolic pathway. It is an intrinsic protective signaling programme to limit cell death activated by the heart.[1] This pathway allows ischaemic postconditioning that helps protect against reperfusion injury.[2] This path involves the activation of a transcription factor called signal transducer and activator of transcription 3 (STAT3).[3]

Activation

A 2011 study concludes, “Our data demonstrate that both melatonin and resveratrol, as found in red wine, protect the heart in an experimental model of myocardial infarction via the SAFE pathway.”[4]
