Suppression of JNK pathway protects neurons from oxidative injury via attenuating parthanatos in glutamate-treated HT22 neurons.

ABSTRACT: Oxidative stress causes diverse neurological disorders. Parthanatos is a type of programmed cell death, characterised by strong activation of poly (ADP-ribose) (PAR) polymerase-1 (PARP-1), PAR polymer accumulation, and nuclear translocation of apoptosis-inducing factor (AIF), and is involved in cellular oxidative injury. Signalling by c-Jun-N-terminal protein kinase (JNK) is activated by reactive oxygen species (ROS), and this also contributes to ROS production. However, the exact relationship between JNK signalling and parthanatos in neurological disorders triggered by oxidative stress is unclear. In this study, glutamate-treated HT22 neurons were used to investigate whether the signalling by JNK contributes a regulatory role to parthanatos in oxidative stress-related neurological disease
