Extracellular glutathione peroxidase (GPx3) is a secreted selenoenzyme with GPx activity. GPx3 in plasma is predominantly derived from the proximal tubules of kidneys in humans. Previous studies have shown differences in the expression level of GPx3 in serum from patients with diabetic nephropathy. In this study, the regulation of GPx3 under a high glucose condition in human proximal tubular (HK-2) cells was studied. When HK-2 cells were treated with different concentrations for 72 h, glucose did not show any cytotoxic effects as judged by MTS assay, but only decreased HK-2 metabolic activity. The glucose concentration of the cultured medium in which the cells were grown showed only 5 mM glucose. Cells exposed to hyperglycemia was provided the same osmotic stress. Both GPx3 mRNA expression of HK-2 and GPx3 protein were increased in osmotic condition as well as hyperglycemia condition. In results, hyperglycemia condition damaged the cell by providing osmotic shock as a hyperosmotic condition. Under hyperglycemia condition, GPx3 as a antioxidant enzyme was increased in HK-2 cells for protection from osmotic stress.
