A role of sodium selenite in regulating expression of cyclooxygenase-2 in rat mesangial cells / 中华内分泌代谢杂志

ABSTRACT

The expression of cyclooxygenase-2 (COX-2) mRNA and protein was significantly increased in rat glomerular mesangial cells (RCMC) treated separately with high glucose, high insulin, H2 O2 and advanced glycosylation end products. The expressions of COX-2 mRNA and protein in RCMC induced by above 4 factors were distinctly inhibited by sodium selenite, suggesting that sodium selenite might play a significant role in the prevention of diabetic nephropathy via this mechanism.
