JNK1 and JNK3 play a significant role in both neuronal apoptosis and necrosis. Evaluation based on in vitro approach using tert-butylhydroperoxide induced oxidative stress in neuro-2A cells and perturbation through 3-aminobenzamide.

In spinal cord injury (SCI), oxidative stress in the penumbra of the injury site is a characteristic feature. The predominance of necrosis over apoptosis in the ensuing delayed cell death results in progressive waves of necrosis affecting neighboring cells and thus exaggerates the severity of the lesion. Necrosis has been classified into subtypes based on the active molecular players and parthanatos is one among them, which is characterized by the over activation of PARP1 as the pre-mitochondrial event that triggers necrosis.

Novel neurotrophic factor secreted by amniotic epithelial cells.

By virtue of expressions of glial and neural surface markers and capability of neurotransmitter metabolism, amniotic epithelial cells are considered as candidate cell type for transplantation strategies to treat neurological disorders. Previously, we have reported neurotrophism exhibited by human amniotic epithelial cells when transplanted after spinal cord injury in bonnet monkeys. Amniotic epithelial cells were believed to secrete an "Epidermal Growth Factor (EGF)-like" factor and exact identification was not made.
