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.


Packaged under Argon.

This study was designed to investigate the neuroprotective effects of baicalein and the effect of the cortical 12/15-lipoxygenase (12/15-LOX) pathway on diabetic cognitive dysfunction. Our results showed that spatial learning and memory ability, as well as cortex neurons, were significantly...

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...

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...

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...

The intravasation of breast cancer into the lymphendothelium is an early step of metastasis. Little is known about the mechanisms of bulky cancer invasion into lymph ducts. To particularly address this issue, we developed a 3-dimensional co-culture model involving MCF-7...
