Because several studies have postulated a role for prostaglandins (PGs) in the glomerular hyperfiltration seen in early diabetes, we evaluated the effect of mitochondrial ROS on expression of the inducible isoform of cyclooxygenase (COX-2) in cultured human mesangial cells (HMCs...

FIG. 2. Effects of high glucose on the expression of COX and prostaglandin production in isolated BCAs. A: High glucose increases the detections of COX-2. Isolated BCAs were exposed to normal glucose (5 mmol/l, control), high glucose (30 mmol/l), or mannitol for 4 h as described in research design and methods. The levels of COX-1 and -2 were detected in Western blots using the specific antibodies. The blot is a representative of three blots obtained from three independent experiments. B: High glucose increases PGE2 synthesis. Isolated BCAs were exposed to normal glucose (5 mmol/l, control), high glucose (30 mmol/l), or mannitol for 4 h. At the end of incubation, the media were collected and analyzed for PGs, as indicated in research design and methods. The results are expressed as means ± SD (n = 8; †P < 0.01, 5 vs. 30 mmol/l glucose). FIG. 2. Effects of high glucose on the expression of COX and prostaglandin production in isolated BCAs.
