Control of extracellular thiol-disulfide redox potential (E(h)) is necessary to protect cell surface proteins from external oxidative and reductive stresses. Previous studies show that human colonic epithelial Caco-2 cells, which grow in cell culture with the apical surface exposed to the medium, regulate extracellular cysteine/cystine E(h) to physiological(More)
BACKGROUND It is known that malaria infection is accompanied by increased production of reactive oxygen species (ROS) and that malaria parasites are sensitive to oxidative damage. This has been proved by the efficacy of some antimalarial drugs that are known to act via generation of ROS when administered clinically or experimentally. OBJECTIVE There is(More)
Following massive small bowel resection in animal models, the remnant intestine undergoes a dynamic growth response termed intestinal adaptation. Cell growth and proliferation are intimately linked to cellular and extracellular thiol/disulfide redox states, as determined by glutathione (GSH) and GSH disulfide (GSSG) (the major cellular redox system in(More)
