Endoplasmic reticulum (ER) stress caused by excessive aggregation of misfolded proteins induces apoptosis. Although ER stress-induced apoptosis has been implicated in many diseases, the detailed mechanisms are not well understood. Here, we identified human transmembrane protein 214 (TMEM214) as a critical mediator of ER stress-induced apoptosis. Overexpression of TMEM214 induced apoptosis, wher...
Portulaca oleracea Protects H9c2 Cardiomyocytes Against Doxorubicin-Induced Toxicity by Inhibition of Oxidative Stress and Apoptosis
Purpose: To investigate the role of dexmedetomidine in gastric ischemia/reperfusion injury using mucosal epithelial cell (GES-1) model.
 Methods: GES-1 were subjected to oxygen-glucose deprivation conditions, followed by increasing concentrations (0.5, 1.0, or 1.5 μM) for 4 h reoxygenation. Cell viability and apoptosis determined 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bro...
objective(s):hypoxia induces cellular oxidative stress that is associated with neurodegenerative diseases. here, the protective effects of ferulic acid (fa) on hypoxia-induced neurotoxicity in pc12 cells were evaluated. materials and methods:we investigated the effect of fa on pc12 cells subjected to hypoxia stress, in vitro. results:fa increased cell viability, prevented membrane damage (ldh r...
objective(s): oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. licochalcone b, an extract of licorice root, has shown antioxidative properties. this study was to investigate the effects and mechanisms of licochalcone b in ethanol-induced hepatic injury in an in vitro study. materials and methods: an in vitro model of ethanol-induced cytotoxicity in brl cel...
Lai E, Bikopoulos G, Wheeler MB, Rozakis-Adcock M, Volchuk A. Differential activation of ER stress and apoptosis in response to chronically elevated free fatty acids in pancreatic -cells. Am J Physiol Endocrinol Metab 294: E540–E550, 2008. First published January 15, 2008; doi:10.1152/ajpendo.00478.2007.—Chronic exposure to elevated saturated free fatty acid (FFA) levels has been shown to induc...
Abstract During normal cellular activities Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) are produced. In addition to beneficial functions they play a critical role in cell death and prevent apoptosis. Every cell is equipped with an extensive antioxidant defense system to combat the excessive production of active radicals. Oxidative stress occurs with destruction of cellu...
Background and Objective: Excessive production of free radicals during oxidative stress can cause serious damage to important biomolecules and activate programmed cell death pathways in the body. In the nervous system, neuronal cell death leads to many progressive neurodegenerative disorders. The aim of this study was to evaluate the effects of adenosine on the inhibition of apoptosis in oxidat...
