Cellular stress may stimulate cell survival pathways or cell death depending on its severity. 6-Hydroxydopamine (6-OHDA) is a neurotoxin that targets dopaminergic neurons that is often used to induce neuronal cell death in models of Parkinson's disease. Here we present evidence that 6-OHDA induces apoptosis in rat PC12 cells that involves release of(More)
A mild heat shock preconditioning has been shown to induce thermotolerance and protection against a number of cytotoxic agents that may induce cell death by either apoptosis or necrosis. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a neurotoxin that selectively targets dopaminergic cells of the substantia nigra and, as such, it is often used to(More)
