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.

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
