“dRib produced the intracellular glutathione depletion in a dose–dependent manner” We used two methods based on a different principle, mBCl assay and a Cayman glutathione kit, for assessing the changes in intracellular GSH levels. They showed 6h–stimulation with various concentrations of dRib significantly and dose–dependently decreased the intracellular amounts of reduced and total glutathiones in HIT–T15 cells. These results clearly demonstrated that dRib depleted the intracellular GSH content in HIT–T15 cells.
