Sex steroid modulation of fatty acid utilization and fatty acid binding protein concentration in rat liver.
The mechanism by which sex steroids influence very low density hepatic lipoprotein triglyceride production has not been fully elucidated. In previous studies we showed that [(14)C]oleate utilization and incorporation into triglycerides were greater in hepatocyte suspensions from adult female rats than from males. The sex differences were not related to activities of the enzymes of triglyceride ...
متن کاملStudies on fatty-acid-binding proteins. The purification of rat liver fatty-acid-binding protein and the role of cysteine-69 in fatty acid binding.
1. A new, simple and high-yield procedure is described for the purification of hepatic fatty-acid-binding protein from rat liver using naphthylaminodecyl-agarose as an affinity column. 2. Cysteine-69 is shown to react slowly, but quantitatively, with 5,5'-dithiobis-(2-nitrobenzoic acid) (DTNB), indicating that the thiol group is free, but may be buried within the protein. 3. Fatty acids do not ...
متن کاملHeart-type fatty acid-binding protein reciprocally regulates glucose and fatty acid utilization during exercise.
The role of heart-type cytosolic fatty acid-binding protein (H-FABP) in mediating whole body and muscle-specific long-chain fatty acid (LCFA) and glucose utilization was examined using exercise as a phenotyping tool. Catheters were chronically implanted in a carotid artery and jugular vein of wild-type (WT, n = 8), heterozygous (H-FABP(+/-), n = 8), and null (H-FABP(-/-), n = 7) chow-fed C57BL/...
متن کاملRequirement for the heart-type fatty acid binding protein in cardiac fatty acid utilization.
Nonenzymatic cytosolic fatty acid binding proteins (FABPs) are abundantly expressed in many animal tissues with high rates of fatty acid metabolism. No physiological role has been demonstrated for any FABP, although these proteins have been implicated in transport of free long-chain fatty acids (LCFAs) and protection against LCFA toxicity. We report here that mice lacking heart-type FABP (H-FAB...
متن کاملEnterocyte fatty acid uptake and intestinal fatty acid-binding protein.
This article reviews our current understanding of the uptake of fatty acids by the enterocytes of the intestine. The micellar solubilization of fatty acids by bile salts and the factors regulating that process are discussed. The mechanism of how micellar solubilization of fatty acids promotes the uptake of fatty acids by enterocytes and their relative importance is reviewed. Additionally, discu...
