Objective:To observe the effect of sodium selenite on expression of Cyclooxygenase-2 (COX-2) mRNA in rat mesangial cells (RGMC)
and to study the mechanism of sodium selenite in anti-diabetic nephropathy.Methods:RGMC was incubated with high glucose
advanced glycosylation end products (AGE)
high insulin and H

respectively;simultaneously
RGMC pre-treated with sodium selenite was incubated with above factors.The expression of COX-2 mRNA was detected and compared.Results:The four factors increased the expression of COX-2 mRNA independently;sodium selenite inhibited the expression of COX-2 mRNA by the four factors distinctly.Conclusion:Sodium selenite suppresses the expression of COX-2 mRNA in RGMC
which suggests that sodium selenite may play a significant role in the prevention of diabetic nephropathy by inhibition of the expression of COX-2 mRNA in RGMC.
