Abstract：
:In this study, we showed that nitric oxide (NO) donors induced the mesangial cell proliferation and cyclooxygenase-2 (COX-2) protein expression in murine mesangial cells. An inflammatory condition [lipopolysaccharide (LPS) plus interferon-gamma (IFN-gamma)] could also induce cell proliferation and significantly enhance inducible nitric oxide synthase (iNOS) and COX-2 expression. Phosphoinositide 3-kinase (PI3K) inhibitor, LY294002, inhibited these responses. LPS/IFN-gamma-induced COX-2 expression in mesangial cells could be inhibited by iNOS inhibitor, aminoguanidine. Selective COX-2 inhibitor, NS398, was capable of inhibiting NO donor- or LPS/IFN-gamma-induced mesangial cell proliferation. Both NO donor and LPS/IFN-gamma markedly activated the PI3K activity and the phosphorylation of Akt and nuclear factor (NF)-kappaB DNA binding activity in mesangial cells, which could be inhibited by LY294002 and transfection of dominant-negative vectors of PI3K/p85 and Akt. These results indicate that a PI3K/Akt-dependent pathway involved in the NO-regulated COX-2 expression and cell proliferation in mesangial cells under inflammatory condition.
