Declining SIRT3 activity leaves SOD2, IDH2, and permeability-transition regulators hyperacetylated, reducing mitochondrial antioxidant capacity, NADPH support, and resistance to pore opening. Increased ROS and energetic failure can then further suppress NAD+-dependent SIRT3 function, forming a secondary resilience-collapse loop. This is biologically coherent but currently the least direct and least well-validated self-amplifying mechanism.
Oxidative DNA damage hyperactivates PARP1, rapidly consuming NAD+ and collapsing ATP production. Bioenergetic failure impairs mitochondrial respiration, increases ROS, promotes PAR polymer signaling and AIFM1 translocation, and thereby feeds additional oxidative damage back into the system. This is the clearest closed feedback loop linking ROS, organelle failure, and executioner death signaling.
