Insufficient KEAP1-NRF2-ARE signaling reduces glutathione synthesis, quinone detoxification, and peroxide buffering, leaving neurons unable to extinguish mitochondrial and cytosolic ROS once stress begins. The resulting oxidative injury further impairs transcriptional competence and mitochondrial function, creating a permissive feedback architecture. This is a strong systems-level modifier, though less clearly the singular core loop than PARP or ferroptosis models.
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.
