NADPH oxidase activity, which was significantly enhanced in diabetic glomeruli and the source of reactive oxygen species (ROS) generation, was also improved by RBX treatment by preventing the membranous translocation of p47phox and p67phox from cytoplasmic fraction without affecting their protein levels.

Adenoviral-mediated PKC-beta(2) overexpression enhanced ROS generation by modulating the membranous translocation of p47phox and p67phox in cultured mesangial cells.

The kidneys of rats with DM had increased expression of p47phox and gp91phox and endothelial nitric oxide synthase (eNOS), and increased mesangial matrix with expression of fibronectin and collagen I.

Activation of NADPH oxidase with translocation of p47phox to the membrane underlies the oxidative stress and limited NO generation, despite enhanced eNOS expression in a model of diabetic nephropathy.

At the end of 4, 8, and 12 weeks, hydroxyproline content, NADPH oxidase activity and the expression of phosphorylation of inositol-requiring enzyme-1alpha (p-IRE1alpha), p47phox, nitrotyrosine (NT) and NF-E2-related factor 2 (Nrf2) in the kidneys of all rats were determined; malondialdehyde (MDA) levels and superoxide dismutase (SOD) activity in serum and urine were also detected; renal nuclear factor kappaB (NF-kappaB) activity in all of the rats was examined at the end of 12 weeks.

Compared with the NC group, the DN rats showed a significant increase in hydroxyproline content, NADPH oxidase activity, NF-kappaB activity, the expression of p-IRE1alpha, p47phox, NT and Nrf2 in renal tissue; markedly, MDA levels were higher and SOD activity was lower in serum and urine of DN rats than in NC rats for the indicated time.

SM produced a significant decrease in monocytic interleukin-1? and COX-2 levels and prevented oxidant formation caused by S100b, which appeared to be mediated by inhibition of p47phox membrane translocation.

Silencing TLR2, TLR4, and p47phox with small inhibitory RNAs (siRNAs) significantly reduced superoxide release, NF-?B activity, IL-1?, and MCP-1 secretion in HG and palmitate-treated THP-1 cells.

With a single injection of streptozotocin 65 mg/kg, ip in rats, early diabetic nephropathy was produced and revealed as an increased microalbuminuria, elevated creatinine and urea in serum, associated with upregulation of mRNA and protein of NADPH oxidase p22phox, p47phox, and p67phox and ET(A), upregulated PKR-like eukaryotic initiation factor 2? kinase (PERK), and downregulated Cx43 in the renal tissue.

This premature p47phox translocation and preassembly with p22phox were also observed in HL-60 cells cultured with high glucose (HG; 25 mM) and with the specific ligand for the receptor for advanced glycation end products (RAGE), S100B.

Phosphorylation of ERK1/2, but not p38 MAPK, was the primary signaling pathway, as evidenced by PD98059 suppressing the translocation of p47phox in HL-60 cells incubated with HG and S100B.

Exposure of MCs to AOPPs, through membrane-associated phosphorylation of PKCalpha, induced rapid phosphorylation of cytosolic p47(phox) and its membrane translocation, enhanced interaction of p47(phox) with the membrane components p22(phox) and Nox4, and increased expression of these key regulatory subunits of NADPH oxidase.

Expression of NADPH oxidase was examined and p47phox translocation was assessed.

Furthermore, NADPH oxidase was highly activated in monocytes represented by p22phox up-regulation and p47phox translocation.

In STZ rats, atorvastatin feeding (20 mg/kg/d, 7 weeks), normalized vascular dysfunction as analyzed by isometric tension studies, levels of circulating endothelial progenitor cells (FACS-analysis), superoxide formation (assessed by lucigenin-enhanced chemiluminescence and dihydroethidium staining), vascular levels of the phosphorylated vasodilator-stimulated phosphoprotein (P-VASP), tyrosine nitration of the prostacyclin synthase, expression of GTPCH-I, dihydrofolate reductase and eNOS, translocation of regulatory NADPH oxidase subunits rac1, p47phox and p67phox (assessed by Western blot) and vascular tetrahydrobiopterin levels as measured by HPLC.

Glycated albumin-induced TGF-beta expression and extracellular matrix production (fibronectin) was also inhibited by p47phox knock down.

|
Taken together, these data suggest that up-regulation of p47phox is involved in glycated albumin-mediated activation of NADPH oxidase, leading to glycated albumin-induced expression of TGF-beta and extracellular matrix proteins in mesangial cells and contributing to the development of diabetic nephropathy.

NADPH oxidase activity was assessed using lucigenin-derived chemiluminescence and a cyotochrome c assay. p47phox translocation to the plasma membrane, Nox2, superoxide dismutase 1 (SOD1), and SOD2 mRNA and protein levels were determined by real-time polymerase chain reaction and Western blotting.

Further studies revealed that HG treatment resulted in phosphorylation and membrane translocation of Rac1, p47phox, and p67phox subunits leading to NADPH oxidase activation.
