Gastrodia elata (G. elata) is a traditional Chinese herbal medicine for treating headaches, dizziness, tetanus, and epilepsy. In this study, differential methanol (MeOH) extracts of G. elata were found to prevent serum-deprived rat pheochromocytoma (PC12) cell apoptosis by the MTT assay and Hoechst staining. A serine/threonine kinase inhibitor attenuated this protection. G. elata resulted in phosphorylation and dephosphorylation of ERK1/2 and JNK1/2-p38 MAPKs (members of the serine/threonine kinase family), respectively, as revealed by Western blot analysis. An upstream ERK inhibitor attenuated G. elata-induced ERK phosphorylation but not protective effect. Although JNK and p38 inhibitors attenuated their related enzyme activities during serum deprivation, only JNK inhibitor prevented serum-deprived apoptosis. Thus, G. elata prevents serum-deprived apoptosis through activation of the serine/threonine kinase-dependent pathway and suppression of JNK activity.
