Target Background

Constitutive NADPH oxidase which generates superoxide intracellularly upon formation of a complex with CYBA/p22phox. Regulates signaling cascades probably through phosphatases inhibition. May function as an oxygen sensor regulating the KCNK3/TASK-1 potassium channel and HIF1A activity. May regulate insulin signaling cascade. May play a role in apoptosis, bone resorption and lipolysaccharide-mediated activation of NFKB.
Gene References into Functions
  1. Data suggest that Nox4 aggravates cisplatin-induced nephrotoxicity (acute kidney injury) by promoting ROS-mediated programmed cell death (oxidative stress and apoptosis) and by promoting inflammation in mouse kidney, mouse/human renal tubular cells, and transformed human kidney cell line. (ROS = reactive oxygen species) PMID: 29106395
  2. Gene analysis indicated that soluble epoxide hydrolase 2 (sEH) was significantly upregulated in Nox4DN endothelial cells (EC). Inhibition of sEH activity in Nox4DN EC suppressed inflammation and macrophage adhesion to EC. PMID: 28185955
  3. Our study provides strong evidence that Egr1 is a transcriptional activator of NOX4 in oxidative stress of DKD. Egr1 contributes to diabetic kidney disease by enhancing EMT, in part by targeting NOX4. PMID: 29854821
  4. High glucose induced histone H3K27 acetylation enrichment at the promoters of Nox1/4/5 genes in SMCs. The novel data of this study indicate that HDACs mediate vascular Nox up-regulation in diabetes.

  12. Strong dityrosine formation was observed, but was significantly weaker in NOX4-/- mice (p<0.05). NOX2, HIF1alpha and CD31 expression was significantly weaker in NOX4-/- mice (p<0.05). In this study we show for the first time that NOX4 plays a role in cutaneous wound repair. PMID: 27140231

  16. we used the Ang II infused hph-1 mice to examine the roles of NOX isoforms in the development of AAA. We generated double mutants of hph-1-NOX1, hph-1-NOX2, hph-1-p47phox, and hph-1-NOX4 PMID: 27912196

  25. Nox4 is upregulated in pericytes in peri-infarct areas after acute brain ischemia and may enhance blood-brain barrier breakdown through activation of NFkappaB and matrix metalloproteinase 9, thereby causing enlargement of infarct volume. PMID: 26661159
  26. Deficiency of NOX4 resulted in reduced expression of carnitine palmitoyltransferase 1A (CPT1A), which is a key mitochondrial enzyme in the fatty acid oxidation (FAO) pathway. The reduced FAO resulted in less activation of the nucleotide-binding domain, leucine-rich-repeat-containing receptor (NLR), pyrin-domain-containing 3 (NLRP3) inflammasome in macrophages.
