Neuronal apoptotic death generally requires de novo transcription, and activation of the transcription factor c-Jun has been shown to be necessary in multiple neuronal death paradigms. Caspase-2 has been implicated in death of neuronal and non-neuronal cells, but its relationship to transcriptional activation has not been clearly elucidated. In the present study, using two different neuronal apoptotic paradigms, β-amyloid treatment and NGF (nerve growth factor) withdrawal, we examined the hierarchical role of caspase-2 activation in the transcriptional control of neuron death. Both paradigms induce rapid activation of caspase-2 as well as activation of the transcription factor c-Jun and subsequent induction of the pro-apoptotic BH3 (Bcl-homology domain 3)-only protein Bim (Bcl-2-interacting mediator of cell death). Caspase-2 activation is dependent on the adaptor protein RAIDD {RIP (receptor-interacting protein)-associated ICH-1 ICE (interleukin-1β-converting enzyme)/CED-3 (cell-death determining 3) homologue 1 protein with a death domain}, and both caspase-2 and RAIDD are required for c-Jun activation and Bim induction. The present study thus shows that rapid caspase-2 activation is essential for c-Jun activation and Bim induction in neurons subjected to apoptotic stimuli. This places caspase-2 at an apical position in the apoptotic cascade and demonstrates for the first time that caspase-2 can regulate transcription.
