Our results showed that UFPs, at a non-toxic dose, induced reactive oxygen species (ROS) generation in mouse pulmonary microvascular endothelial cells (MPMVEC) that was inhibited by pre-treatment with the ROS scavengers or inhibitors, but not with the mitochondrial inhibitor, rotenone.
Moreover, Western blot and immunofluorescence staining results showed that MPMVEC treated with UFPs resulted in the translocation of cytosolic proteins of NADPH oxidase, p47 (phox), p67 (phox) and rac 1, to the plasma membrane.

In contrast, inhibitors of other oxidant-producing enzymes, including the mitochondrial complex Iinhibitor rotenone, the xanthine oxidase inhibitor allopurinol, the cyclooxygenase inhibitor indomethacin, the lipoxygenase inhibitor nordihydroguiaretic acid, the cytochrome P450 oxygenase inhibitor ketoconazole and the nitric oxide synthase inhibitor G-nitro-L-arginine methyl ester were without an effect.
Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity was examined by lucigenin chemiluminescence. p47phox and p67phox translocation was assayed by Western blot.

Am J Physiol Lung Cell Mol Physiol. 2003 Jan;284(1):L26-38. Epub 2002 Jul 26.

Exposure of HPAECs to hyperoxia for 1, 3, and 12 h increased the generation of superoxide anion, which was blocked by diphenyleneiodonium but not by rotenone or oxypurinol.
Immunohistocytochemistry and Western blotting revealed the presence of gp91, p67 phox, p22 phox, and p47 phox subcomponents of NADPH oxidase in HPAECs.

The involvement of nicotinamide-adenine dinucleotide diphosphate oxidase in the enhanced 02*- production was demonstrated by the finding that the cytosolic components of the enzyme, p47phox and p67phox, were both translocated to the plasma membrane of enriched but otherwise unmanipulated monocytes of SSc patients.
The involvement of mitochondrial oxidases was excluded by the lack of inhibition of O2*- production when monocytes were incubated in the presence of rotenone, a mitochondrial oxidase inhibitor.

This was independent of mitochondrial ROS production, because it was unaffected by mitochondrial depolarization with rotenone and oligomycin.
Expression of gp91phox and p67phox was increased in reactive astrocytes, which showed increased rates of both resting and stimulated ROS generation.

In contrast, inhibitors of other oxidant-producing enzymes, including the mitochondrial complex I inhibitor rotenone, the xanthine oxidase inhibitor allopurinol, the cyclooxygenase inhibitor indomethacin, the lipoxygenase inhibitor nordihydroguiaretic acid, the cytochrome P-450 oxygenase inhibitor ketoconazole, and the nitric oxide synthase inhibitor N (G)-nitro-l-arginine methyl ester, were without effect.
ANG II induced translocation of p47 (phox) and p67 (phox) from the cytosol to the membrane.

Arterioscler Thromb Vasc Biol. 2003 Mar 1;23(3):418-24. Epub 2003 Feb 13.

METHODS AND RESULTS: The increased generation of O2*- by HHcy coronary arteries was inhibited by SOD, diphenyleneiodonium, apocynin, and apocynin plus amino guanidine but was unaffected by allopurinol and rotenone.
Expression of p67phox, p22phox, and p47phox subunits and that of endothelial nitric oxide synthase, Cu,Zn-SOD, Mn-SOD, extracellular SOD (mRNA), and xanthine oxidase was unchanged.

In this study, using Western blot analysis we found that the major Nox subunits Nox1, Nox4, p22 (phox), p47 (phox), and p67 (phox) were equivalently expressed in mouse pulmonary and systemic (mesenteric) arteries.
Inhibition of mitochondrial ROS generation with rotenone or myxothiazol prevented hypoxic activation of Nox.

NADPH or NADH elicited superoxide anion and hydrogen peroxide generation by isolated triads; both activities were inhibited by NOX inhibitors but not by rotenone.
