Figure 2. Urea-induced mitochondrial reactive oxygen species cause proinflammatory changes in endothelial cells.
HAEC were incubated with 20mM urea alone or 20 mM urea after infection with adenoviral vectors expressing UCP-1 or MnSOD. After 48 hrs PGI2 Synthase activity (A) NFκB p65 and NFκB-specific target genes mRNA expression (B) MCP-1 (C) VCAM1 (D) protein levels were measured. Each bar represents the mean±SEM of 5 separate experiments, each with n = 3. *p<0.01 compared with cells not treated with urea.
