Metabolism of oxygenated derivatives of arachidonic acid by Caco-2 cells.
Monolayers of Caco-2 cells, a human enterocyte cell line, were incubated separately with 3H8-labeled preparations of three different lipid mediators of inflammation: 5-hydroxyeicosatetraenoic acid, 12-hydroxyeicosatetraenoic acid, and leukotriene B4. Both [3H8]5-hydroxyeicosatetraenoic and [3H8]12-hydroxyeicosatetraenoic acids were taken up and metabolized by Caco-2 cells, but [3H]leukotriene B...
متن کاملUptake and metabolism of structured triglyceride by Caco-2 cells: reversal of essential fatty acid deficiency.
Structured lipids have been proposed as efficient vehicles for the supplementation of essential fatty acids (EFA) to patients with malabsorption. We investigated how a novel structured triglyceride (STG), containing purely octanoic acid in the sn-1/ sn-3 and [14C]linoleic acid in the sn-2 positions, was incorporated into different lipid classes in Caco-2 cells. We also evaluated the contributio...
متن کامل15-Hydroxyeicosatetraenoic acid (15-HETE) protects pulmonary artery smooth muscle cells against apoptosis via HSP90.
AIMS 15-Hydroxyeicosatetraenoic acid (15-HETE), generated by hypoxia, is a product of arachidonic acid and mainly catalyzed by 15-lipoxygenase (15-LO) in pulmonary artery. As HSP90 is known to be involved in apoptosis in other tissues and cells, we aim to test whether anti-apoptotic effect of 15-HETE is regulated by the molecular chaperone in pulmonary artery smooth muscle cells. MAIN METHODS...
متن کاملEffects of intestinal fatty acid-binding protein overexpression on fatty acid metabolism in Caco-2 cells.
Intestinal fatty acid-binding protein (I-FABP) is a cytosolic protein expressed at high levels (up to 2% of cytosolic proteins) in the small intestine epithelium. Despite cell transfection studies, its function is still unclear. Indeed, different effects on fatty acid metabolism depending on the cell type and the amount of I-FABP expressed have been reported. Furthermore, a decrease in fatty ac...
متن کاملFatty acid uptake by Caco-2 human intestinal cells.
The Caco-2 human enterocytic cell line was used to study the kinetics and mechanism of intestinal long chain fatty acid uptake. Initial rates of palmitate (16:0), oleate (18:1), and octanoate (8:0) uptake were determined for adherent cells at greater than 7 days confluence. Uptake of long chain 18:1 and 16:0 by cells grown on coverslips was saturable with an apparent Km of 0.3 microM, but also ...
