Platelets of patients with uremia develop a defective platelet function and have a decreased production of thromboxane B2 (TxB2). Activated platelets generate thromboxane from free arachidonate that is previously released from the membrane phospholipids (PLs) by phospholipases. Phospholipase A2 (PLA2)
Polychlorinated biphenyls (PCBs) are stable compounds commonly found in nature as environmental pollutants. PCBs can affect the endocrine function of hormones such as steroid-hormones. Also, PCBs are known to be inducers of arachidonic acid release in various cells. We report

We investigated the effects of certain dietary polyunsaturated fatty acids (PUFAs) and related eicosanoids on the growth and metastasis formation of a murine mammary gland adenocarcinoma. Salvia hispanica (ChO) and Carthamus tinctorius (SaO) vegetable oil sources of omega-3 and -6

It is shown that 12-(S)-hydroxy-(5Z, 8E, 10E)-heptadecatrienoic acid (5-cis-HHT)--a physiological metabolite of arachidonic acid--is acid-catalyzed converted into a less polar substance with its maximum UV-absorption at (1)max=232 nm and a molar absorptivity of about epsilon=26600 +/- 200 M(-1)cm(-1). Using a

Both 12-hydroxyheptadecatrienoic acid (12-HHT) and thromboxane A2 (TXA2) are products derived from prostaglandin H2 (PGH2) catalyzed by thromboxane synthase. Whether or not they exhibit similar actions remains to be determined. While TXA2-induced activation of extracellular signal-regulated kinases (ERKs) has been
