Biochem/physiol Actions

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.

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.
