자원 수유출물이 H2O2에 의해 유도된 PC-12 세포말의 세포사에 미치는 영향

Objective : Alzheimer's disease (AD) is a geriatric dementia that is widespread in old age. With an aging populace, AD is a looming problem in public health service. Alzheimer's disease is characterized by specific neuronal degeneration in certain areas of the brain. Mutations and abnormal expression of several genes are associated with β-amyloid deposits and Alzheimer's disease; among them APP, PS1, and PS2, SOD, free radical, ROS. Methods:We studied herbal medicines that have a relationship to brain degeneration. From pre-modern times, although a variety of oriental prescriptions of Aster tataricus have been traditionally utilized for the treatment of AD, their pharmacological effects and action mechanisms have not yet been fully elucidated. Result : Based on morphological observations by phase-contrast microscope, TUNEL assay and MTT in the culture media, H2O2-induced cell death was significantly inhibited by Aticus. We examined by ROS formation, catalase activity and GSH activity. We studied the protective effect and inhibitory effects of neurotoxicity in H2O2-induced PC-12 cells by Aticus. Findings from our experiments show that Aticus inhibits apoptosis, which has neurotoxicities and cell damage in PC-12 cells. In addition, treatment with Aticus (>25㎍/㎖ for 6hrs) partially prevented H2O2-induced cytotoxicity in PC-12 cells, and induced a protective effect. Conclusion : As the result of this study, in the Aticus group, the apoptosis in the nervous system was inhibited, protected against the degeneration of PC-12 cells by H2O2. Taken together, Aticus exhibited inhibition of H2O2-induced apoptotic cell death. Aticus was found to induce protective effect on GSH and catalase in PC-12 cells. Based on these findings, Aticus may be beneficial for the treatment of AD. KCI Citation Count: 0
