Inhibition of long-chain acyl coenzyme A synthetases during fatty acid loading induces lipotoxicity in macrophages.
OBJECTIVE Obesity is often associated with hypertriglyceridemia and elevated free fatty acids (FFAs), which are independent risk factors for cardiovascular disease and diabetes. Although impairment of cholesterol homeostasis is known to induce toxicity in macrophages, the consequence of altered fatty acid homeostasis is not clear. METHODS AND RESULTS Long-chain acyl CoA synthetases (ACSLs) pl...
متن کاملGiardia fatty acyl-CoA synthetases as potential drug targets
Giardiasis caused by Giardia intestinalis (syn. G. lamblia, G. duodenalis) is one of the leading causes of diarrheal parasitic diseases worldwide. Although limited drugs to treat giardiasis are available, there are concerns regarding toxicity in some patients and the emerging drug resistance. By data-mining genome sequences, we observed that G. intestinalis is incapable of synthesizing fatty ac...
متن کاملFATP2 is a hepatic fatty acid transporter and peroxisomal very long-chain acyl-CoA synthetase.
Fatty acid transport protein (FATP)2, a member of the FATP family of fatty acid uptake mediators, has independently been identified as a hepatic peroxisomal very long-chain acyl-CoA synthetase (VLACS). Here we address whether FATP2 is 1) a peroxisomal enzyme, 2) a plasma membrane-associated long-chain fatty acid (LCFA) transporter, or 3) a multifunctional protein. We found that, in mouse livers...
متن کاملComparison of long-chain fatty acyl-CoA synthetases from rabbit heart and liver: substrate preferences and effects of Mg2+.
Rabbit heart has a single, non-specific, fatty acyl-CoA synthetase (HP1) which is dependent on Mg2+, apart from the requirement for MgATP2-. Two long-chain fatty acyl-CoA synthetase activities (LP1 and LP2) can be resolved by hydroxyapatite chromatography of liver preparations; the Mg2+ requirement for these enzymes is undefined. These experiments were done to define the Mg2+ requirements of th...
متن کاملCharacterization of carnitine and fatty acid metabolism in the long-chain acyl-CoA dehydrogenase-deficient mouse.
In the present paper, we describe a novel method which enables the analysis of tissue acylcarnitines and carnitine biosynthesis intermediates in the same sample. This method was used to investigate the carnitine and fatty acid metabolism in wild-type and LCAD-/- (long-chain acyl-CoA dehydrogenase-deficient) mice. In agreement with previous results in plasma and bile, we found accumulation of th...
