To further investigate the role of pioglitazone in H2O2-induced oxidative damage, the NADPH oxidase expression level in mouse embryos treated with H2O2 or H2O2 and pioglitazone was measured.
According to Professor Miesenbock, drugs that change the chemistry of Shaker-bound NADPH, in the same way, could be a powerful new type of sleeping pill.
Apocynin is NADPH oxidase inhibitor that inhibits the aggregation of NADPH oxidase subunits thereby specifically inhibit the activity of NADPH oxidation enzyme.[33] Since NADPH oxidase is the key enzyme in the process of Ang-II-induced OS;[34] moreover, OS plays a significant role in the development of renal interstitial fibrosis; we can come to a conclusion that the apocynin could be used as a protective agent to protect the mitochondrial form being damaged by OS.
Spraying niacin on kiwifruit plants may increase NADPH content, thus increasing NADPH oxidase activity.
Furthermore, mitochondrial and NADPH oxidase are important sources of ROS, and the NADPH oxidase family member of NOX2 exerted an important role in ROS production (40).
The effect of substrate concentration on the velocity of the enzyme reaction was investigated by using varying concentrations of NADPH (0.015-0.24 mM) and DTNB (0.19-3 mM) as substrates.
One liver enzyme indicating OS progression is NADPH oxidase from which ROS is mostly derived [29, 33, 34].
Figure 1: extract ion (m/z 758 [right arrow] 683) chromatograms obtained from LC-LTQ MS analysis of microsomal incubations containing LIM, GSH, NAL, and NADPH in the absence microsomes (A), or in presence of HLMs (B) or MLMs (C).
For examination of the expressions of p47phox (a subunit of NADPH oxidase) and 4-hydroxynonenal (4-HNE) in HSCs in the mouse liver, a double fluorescent staining was performed as described elsewhere [12].
