There was one case of isolated skull osteomyelitis in a nine year old male child.8 Genotype of CGD was available in seven cases, four cases having mutation at gp91phox,7-10 one case with p47-phox11 mutation and in two cases only X-linked pattern was described without description of genetic locus.12,13
CGD is caused by the mutations in four different genes involved in the NADPH oxidase system (i.e., gp91phox, p22phox, p47phox, and p67phox).
also reported that Ang II increased the gp91phox (NOX2) mRNA level, which led to oxidative stress-mediated senescence, whereas treatment with an AT1R blocker attenuated the Ang II-induced gp91phox expression [27].
In trauma, neutrophils produce increased amounts of ROS and increase the expression of gp91PHOX, a membrane-residing subunit of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, a key enzyme in ROS production [44, 45].
By performing this statistical test, we were able to obtain a significant linear inverse relationship between miR-122 level and levels of Gp91phox, Nf-kB, vWF, ICAM1, CD31, c-Jun, and caspase 3 in the SHRSP (Figure 4).

Our results show that obese mice have increased hepatic levels of hepcidin complemented by lower expression of ferroportin and ferritin with increased levels of NRF2 and gp91phox, an indication of oxidative stress.
Nox2, also known as gp91phox, is mostly expressed in macrophages or neutrophils [6].
Qin and Crews (2012b) discovered that LPS and ethanol can increase expression of NADPH oxidase subunits, particularly the superoxide-forming gp91phox subunit, in the brain and that ethanol treatment of mice increased superoxide formation in the brain as well as neuronal death.
Proteins were transferred to polyvinylidene difluoride (PVDF) membranes that were incubated with mouse monoclonal antibodies against endothelial nitric oxide synthase (eNOS, 1:1500; BD, USA), inducible nitric oxide synthase (iNOS, 1:1500; BD), gp91phox (1:1000; BD) and rabbit polyclonal antibodies for [AT.sub.1] (1:500; Santa Cruz Biotechnology, USA) and [AT.sub.2] (1:1000; Millipore, USA).
X-linked gp91phox gene mutation chronic granulomatous disease (CGD) had been diagnosed when he was 4 years of age.
