Biochem/physiol Actions

12(S)-HETE is a bioactive lipid implicated in angiogenesis, growth, and metastasic action in tumor cell lines and in animal models. Arachidonate 12-lipoxygenase (12-LOX) converts arachidonic acid to 12(S)-(HETE). Alteration in 12-LOX expression or activity has been reported in various carcinomas including prostate carcinoma.
Prometastatic metabolite of arachidonic acid via the 12-lipoxygenase pathway that is expressed in many tumor cell lines. It is produced in coronary microvasculature and is a potent inducer of relaxation and hyperpolarization of these microvessels. It activates large-conductance Ca2+-activated K+ currents in coronary microvascular smooth muscle.

Lipids in health and disease, 18(1), 29-29 (2019-01-28)
Altered metabolism of lipids is currently considered a hallmark characteristic of many malignancies, including colorectal cancer (CRC). Lipids are a large group of metabolites that differ in terms of their fatty acid composition. This review summarizes recent evidence, documenting many

As asthma progresses, the levels of IL-33 in serum are markedly increased and contribute to asthmatic development and exacerbation. Mast cells, one of the principal effector cells in the pathogenesis of asthma, express high levels of the IL-33 receptor ST2

Journal of diabetes investigation, 10(3), 639-649 (2018-09-27)
Diabetes is an important risk factor for atherosclerotic disease. The initiating factor of atherosclerosis is local endothelial cell injury. The arachidonic acid metabolite, 12(S)-hydroxyeicosatetraenoic acid (12[S]-HETE), might be involved in this process. In recent years, some studies have discussed the

Many cancers spread through lymphatic routes, and mechanistic insights of tumour intravasation into the lymphatic vasculature and targets for intervention are limited. The major emphasis of research focuses currently on the molecular biology of tumour cells, while still little is

To clarify the effect of 12-lipoxygenase/12-hydroxyeicosatetraeonic acid (12-LOX/12-HETE) on progress of esophageal squamous cell carcinoma (ESCC) and the possible mechanism. We performed cell experiments including chemical treatment, transfection, Western blotting and transwell assay to investigate the function of 12-LOX/12-HETE. Slices
