Research Question¶
The abstract identifies a 'self-amplifying vicious cycle' between redox damage, mitochondrial dysfunction, and multiple death pathways but doesn't explain the specific molecular mechanisms that perpetuate this cycle. Deciphering these feedback loops is essential for breaking the pathological cascade.
