Bafilomycin A1 induces apoptosis in PC12 cells independently of intracellular pH

Abstract

PC12 cells growth-arrested with bafilomycin A1 died showing apoptotic chromatin condensation in the nuclei. The bafilomycin A1-induced chromatin condensation was preceded by neurite outgrowth (NOG), required higher concentrations of bafilomycin A1 than NOG, and was suppressed by cycloheximide and aurintricarboxylic acid. NH4Cl (10 mM), another acidotropic pH perturbing agent, neither induced apoptotic chromatin condensation by itself nor suppressed that induced by bafilomycin A1, suggesting that bafilomycin A1-induced apoptosis occurs independently of intracellular pH in PC12 cells.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
