glutathione/necrosis

The effect of reduced glutathione (GSH) depletion by acetaminophen (APAP), diethylmaleate (DEM), or phorone on the mode of cell death and susceptibility to tumor necrosis factor (TNF)-induced cell death was studied in cultured mouse hepatocytes. Dose-dependent necrosis was the exclusive mode of cell

The role of glutathione (GSH) in the neurotoxicity produced following a single oral dose of 750 mg/kg L-2-chloropropionic acid (L-CPA) has been investigated in rats. L-CPA-induced neurotoxicity was characterised by up to 80-90% loss in cerebellar granule cells and cerebellar oedema leading to

Papillary necrosis was observed in the kidneys of rats, 72 h after receiving a single injection of bromoethylamine (BEA). This effect was associated with renal glutathione (GSH) depletion 1 h after the administration of BEA. Stimulation of renal GSH synthesis by pretreatment of the animals either

A condition of oxidative stress, due to perturbation of oxidant/antioxidant balance, has been suggested to play a role not only in the pathogenesis of human immunodeficiency virus (HIV) infection, but also in the promotion of a thrombophilic condition. Because various hemostatic dysfunctions usually

Intracellular glutathione (GSH) depletion induced by buthionine sulfoximine (BSO) caused cell death that seemed to be apoptosis in C6 rat glioma cells. Arachidonic acid (AA) promoted BSO-induced cell death by accumulating reactive oxygen species (ROS) or hydroperoxides. AA inhibited caspase-3

Infectious spleen and kidney necrosis virus (ISKNV) is the type species of the genus Megalocytivirus, family Iridoviridae. The ISKNV-infected cells in fish tissues are attached by lymphatic endothelial cells (LECs), which is a unique pathological phenomenon of ISKNV infection. The viral proteins

During inflammation and infection, overexpression of the tumor necrosis factor (TNF) is associated with changes in cytochromes P-450 levels in rat and human hepatocytes. The aim of this study was to investigate the effect of TNF on the expression of the glutathione-S-transferases (GSTs) in rat

We investigated the effect of intracellular glutathione (GSH) levels on Natural Killer-mediated apoptosis in cisplatin-resistant K562 cells. K562/B6 and K562/C9 are cisplatin-resistant K562 cells less susceptible to lysis by natural killer cells. Cisplatin-resistant K562 cells did not present the

Lindane is a chlorinated hydrocarbon pesticide, currently used in prescription shampoos and lotions to treat scabies and lice infestations. Lindane is known to be nephrotoxic; however, the mechanism of action is not well understood. In other organ systems, lindane produces cellular damage by

Species differences and mechanisms of 1,2-dibromo-3-chloropropane (DBCP) nephrotoxicity were investigated by studying DBCP renal necrosis and DNA damage, distribution and glutathione-dependent metabolism in rats, mice, hamsters and guinea pigs. Extensive renal tubular necrosis was observed in rats

Mitochondrial glutathione (GSH) plays a key role against tumor necrosis factor alpha (TNF)-induced apoptosis because its depletion is known to sensitize hepatocytes to TNF. The present study examined the role of tauroursodeoxycholic acid (TUDCA) administration to chronic ethanol-fed rats on

Simultaneous or prior exposure to one chemical may alter the concurrent or subsequent response to another chemical, often in unexpected ways. This is particularly true when the two chemicals share common mechanisms of action. The present study uses the paradigm of prior exposure to study the

BACKGROUND RANTES plays an important role in the production of allergic inflammation of the airway through its chemotactic activity for eosinophils. The cellular reduction and oxidation (redox) changes are involved in the activation of p38 mitogen-activated protein (MAP) kinase and the induction of

Tumor necrosis factor (TNF) is an inflammatory cytokine that causes cell injury by generation of oxidative stress. Since glutathione (GSH) is a key cellular antioxidant that detoxifies reactive oxygen species, the purpose of our work was to examine the regulation of cellular GSH, the expression of

A number of inflammatory lung diseases have abnormally low glutathione (GSH) levels in the airway fluids. Lung macrophages are common mediators of inflammation, make up the majority of cells that are found in the airway epithelial lining fluid (ELF), and are commonly elevated in many lung diseases.
