Growing evidence suggests that mediating apoptotic cell death of ER stress plays an important role in pathological development of neurodegenerative diseases including Alzheimer's disease. The ethanol extract of Rodiola sacra (ERS) investigates whether ER stress protects neuroinvasive neuro-2A cells from homocysteine (Hcy) cell death and ER stress. In neuronal cells, Hcy markedly decreased the viability of the cells and induced the death of Annexin V-positive cells as confirmed by MTT assay. The Hcy cell viability and apoptotic loss pretreated with ERS were attenuated, and Hcy showed stress in the expression of C / EBP homologous protein, 78-kDa glucose regulatory protein and the junction of X-box binding protein-1 (xbp1) mRNA. ESR decreased Hcy-induced mRNA binding, GRP78 and CHOP cells induced Hcy-induced ER stress and apoptosis, and Western blotting revealed expression of heme oxygenase-1 and HO-1 enzyme activity Inhibition is indicative of therapeutic value for neurodegenerative diseases such as decreased cell death by hemin.
