Disease relevance of Alox5

  • The 5-LO product inducing lipid body formation was not LTB4 but was 5(S)-hydroxyeicosatetraenoic acid [5(S)-HETE], which was active at 10-fold lower concentrations than PAF and was also inhibited by pertussis toxin but not by zileuton or WEB 2086 [1].
  • These 5LO(-/-) mice were unable to synthesize detectable levels of leukotrienes and were more resistant to lethal anaphylaxis induced by platelet-activating factor [2].
  • We found that 5-LO knockout mice that were treated with a COX inhibitor during allergic sensitization and challenge had significantly increased airway hyperresponsiveness (AHR) (p < 0.01) and airway eosinophilia (p < 0.01) compared with 5-LO knockout mice that were treated with vehicle [3].
  • We also demonstrated that the treatment of AA (1 mumol) and 5-LO metabolites including leukotriene B4 (LTB4) partly mimicked, though soybean LO-derived lipid hydroperoxide and prostaglandins did not, the priming effect evaluated by edema formation and leukocyte infiltration [4].
  • Chronic administration of butylated hydroxytoluene (BHT) to mice stimulates pulmonary inflammation characterized by vascular leakage and macrophage infiltration into the air spaces, increased PGE2 production, and translocation of 5-lipoxygenase (5-LO) from the cytosol to the particulate fraction [5].
 

Psychiatry related information on Alox5

  • METHODS: The following behavioral tests were used for behavioral characterization of 5LOX(-) mice: elevated plus-maze, marble burying, locomotor activity, rota-road, and the spontaneous alternations in T-maze [6].

Biological context of Alox5

 

Anatomical context of Alox5

  • Mechanisms of platelet-activating factor-induced lipid body formation: requisite roles for 5-lipoxygenase and de novo protein synthesis in the compartmentalization of neutrophil lipids [1].
  • Corroborating the dependency of PAF-induced lipid body formation on 5-LO, PMN and macrophages from wild-type mice, but not from 5-LO genetically deficient mice, formed lipid bodies on exposure to PAF both in vitro and in vivo within the pleural cavity [1].
  • Overexpression of BLTR in leukocytes dramatically increased PMN trafficking to skin microabscesses and lungs after ischemia-reperfusion, whereas mice deficient in 5-lipoxygenase (5-LO) showed diminished PMN accumulation in reperfused lungs [18].
  • Also, in BLTR transgenic mice, 5-LO expression and product formation were selectively increased in exudates, demonstrating that receptor overexpression amplifies proinflammatory circuits [18].
  • Consistent with these data, transfer of autoreactive T cells from B6 mice to 5-lipoxygenase-deficient (5-LO-/-) mice, which have a functional defect in LTB4 expression, also failed to induce uveitis in the recipient mice [19].
 

Associations of Alox5 with chemical compounds

  • The intensity of an acute inflammatory response induced by arachidonic acid was similar in 5LO(-/-) mice and controls [2].
  • Dietary celecoxib limited macrophage infiltration, abrogated PGE2 production and reduced particulate 5-LO content [5].
  • It was found that 1mM N6,2-O-dibutyryladenosine 3:5-cyclic monophosphate (dbcAMP) significantly increased the 5-lipoxygenase metabolites, 5-hydroperoxyeicosatetraenoic acid (5-HPETE) and 5-hydroxyeicosatetraenoic acid (5-HETE) [16].
  • We have studied the effect of 5- O-demethylnobiletin ( 1) on both the inflammation of mouse ears induced by repeated application of 12- O-tetradecanoylphorbol 13-acetate (TPA) and the acute mouse paw oedemas induced by carrageenan and phospholipase A (2) (PLA (2)), and determined its activity on 5-lipoxygenase (5-LOX) and elastase release/activity [20].
  • These results indicate that norathyriol inhibits the formation of PGs and LTs in neutrophils probably through direct blockade of COX and 5-LO activities [21].
 

Regulatory relationships of Alox5

  • It has long been proposed that the inhibition of the 5-LO could enhance the COX pathway leading to an increased PG generation [22].
  • These findings indicate the potential role of COX-2 inhibitors and also their combination with the 5-LOX inhibitor in kainic acid induced excitotoxicity and oxidative damage by virtue of their antioxidant effect and suggest the need for the development of dual inhibitors for the treatment of neuronal excitotoxicity [23].
  • Prostaglandins inhibit 5-lipoxygenase-activating protein expression and leukotriene B4 production from dendritic cells via an IL-10-dependent mechanism [24].
  • The addition of sPLA2 to Ag-stimulated mast cells increases the synthesis of 5-LO products [25].
  • A cyclooxygenase inhibitor, a 5-lipoxygenase-activating protein inhibitor and a PAF receptor antagonist did not affect the scratching behavior [26].
