This research investigates how ASK1 influences neuronal apoptosis through the c-Jun N-terminal kinase pathway.
Utilized rat pheochromocytoma (PC12) neuronal cells and primary rat sympathetic neurons (SCGs) for experiments.
Analyzed the effects of ASK1 overexpression and NGF withdrawal on JNK activation and apoptosis.
Employed a kinase-inactive mutant of ASK1 to assess its impact on Cdc42-induced cell death.
ASK1 overexpression activated JNK and resulted in apoptosis in both PC12 and SCG neurons.
NGF withdrawal resulted in a four- to fivefold increase in endogenous ASK1 activity in differentiated PC12 cells.
Kinase-inactive ASK1 inhibited NGF withdrawal- and Cdc42-induced neuronal death and c-jun activation.
