Disease relevance of Cybb

 

High impact information on Cybb

  • Greater bacterial numbers were present in the spleens and livers of gp91phox(-/)- mice compared with C57BL/6 controls as early as day 1 of infection, and all of the gp91phox(-/)- mice succumbed to infection within 5 d [5].
  • Mice with X-linked chronic granulomatous disease (CGD) generated by targeted disruption of the gp91phox subunit of the NADPH-oxidase complex (X-CGD mice) were examined for their response to respiratory challenge with Aspergillus fumigatus [6].
  • We addressed this issue by subjecting leukocyte oxidase (Nox2)-deficient (Nox2-/-) mice to arterial injury [7].
  • Femoral artery injury was associated with increased Nox2 expression, ROS/RNS production, and oxidative protein and lipid modification in wild-type mice [7].
  • Nox1, a homologue of gp91phox, the catalytic moiety of the superoxide (O(2)(-))-generating NADPH oxidase of phagocytes, causes increased O(2)(-) generation, increased mitotic rate, cell transformation, and tumorigenicity when expressed in NIH 3T3 fibroblasts [8].

Associations of Cybb with chemical compounds

 

Regulatory relationships of Cybb

  • Deficiency of gp91phox or inhibition of NADH oxidase blocked TNF-alpha expression stimulated by LPS [19].
  • Hypertension induced by 2K1C was more severe in WT than in gp91phox-/- mice (158+/-2 versus 149+/-2 mm Hg; P<0.05) [21].
 

Other interactions of Cybb

  • This contrasted with Leishmania major infection, which caused rapid lesion growth and death in iNOS knockout mice and some exacerbation of disease with gp91phox deficiency [22].
  • Functional gp91phox and iNOS are required to control S. enterica serovar Typhimurium in non-Slc11a1-regulated phases of infection [22].
  • Deletion of gp91 phox did not alter p22 phox expression but severely inhibited activated O2 species production [1].
  • In the mesenteric arteries the expression of nox4 (4 weeks) and gp91phox (nox2) (8 weeks) subunits of NADPH oxidase from streptozotocin-apoE(-/-) were enhanced as were eNOS mRNA and protein (P<0.05) [23].
  • These data suggest a differential response of the cardiac Nox isoforms, gp91phox and Nox4, to Ang II versus pressure overload [20].
