Caspases mediate 6-hydroxydopamine-induced apoptosis but not necrosis in PC12 cells.

Abstract

The neurotoxin 6-hydroxydopamine (6-OHDA) induces apoptosis in the rat phaeochromocytoma cell line PC12. 6-OHDA-induced apoptosis is morphologically indistinguishable from serum deprivation-induced apoptosis. Exposure of PC12 cells to a low concentration of 6-OHDA (25 microM) results in apoptosis, whereas an increased concentration (50 microM) results in a… (More)
