Sensing of nutrients by CPT1C regulates late endosome/lysosome anterograde transport and axon growth
(eLife Sciences Publications, 2019)
Anterograde transport of late endosomes or lysosomes (LE/Lys) is crucial for proper axon growth. However, the role of energetic nutrients has been poorly explored. Malonyl-CoA is a precursor of fatty ...
Nanomedicine targeting brain lipid metabolism as a feasible approach for controlling the energy balance
(Royal Society of Chemistry, 2023)
Targeting brain lipid metabolism is a promising strategy to regulate the energy balance and fight metabolic diseases such as obesity. The development of stable platforms for selective delivery of drugs, ...
Ghrelin causes a decline in GABA release by reducing fatty acid oxidation in cortex
(Molecular Neurobiology, 2018)
Lipid metabolism, specifically fatty acid oxidation (FAO) mediated by carnitine palmitoyltransferase (CPT) 1A, has been described to be an important actor of ghrelin action in hypothalamus. However, it ...
Central ceramide-induced hypothalamic lipotoxicity and ER stress regulate energy balance
(Elsevier, 2014-10)
Hypothalamic endoplasmic reticulum (ER) stress is a key mechanism leading to obesity. Here, we demonstrate that ceramides induce lipotoxicity and hypothalamic ER stress, leading to sympathetic inhibition, ...
Identification of conserved amino acid residues in rat liver carnitine palmitoyltransferase I critical for malonyl-CoA inhibition. Mutation of methionine 593 abolishes malonyl-CoA inhibition
(American Society for Biochemistry and Molecular Biology, 2003-03-14)
Carnitine palmitoyltransferase (CPT) I, which catalyzes the conversion of palmitoyl-CoA to palmitoylcarnitine facilitating its transport through the mitochondrial membranes, is inhibited by malonyl-CoA. ...
Structural (betaalpha) 8 TIM barrel model of 3-hydroxy-3-methylglutaryl-coenzyme A lyase
(American Society for Biochemistry and Molecular Biology, 2003)
This study describes three novel homozygous missense mutations (S75R, S201Y, and D204N) in the 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) lyase gene, which caused 3-hydroxy-3-methylglutaric aciduria in ...
CPT1c is localized in endoplasmic reticulum of neurons and has carnitine palmitoyltransferase activity
(American Society for Biochemistry and Molecular Biology, 2008)
CPT1c is a carnitine palmitoyltransferase 1 (CPT1) isoform that is expressed only in the brain. The enzyme has recently been localized in neuron mitochondria. Although it has high sequence identity with ...
CPT1A in AgRP neurons is required for sex-dependent regulation of feeding and thirst
(Springer Nature, 2023)
Background: Fatty acid metabolism in the hypothalamus has an important role in food intake, but its specific role in AgRP neurons is poorly understood. Here, we examined whether carnitinea palmitoyltransferase ...
Central regulation of brown fat thermogenesis in response to saturated or unsaturated long-chain fatty acids
(MDPI, 2023)
Sensing of long-chain fatty acids (LCFA) in the hypothalamus modulates energy balance, and its disruption leads to obesity. To date, the effects of saturated or unsaturated LCFA on hypothalamic-brown ...
Liver CPT1A gene therapy reduces diet‐induced hepatic steatosis in mice and highlights potential lipid biomarkers for human NAFLD
(John Wiley & Sons, Inc., 2020)
The prevalence of nonalcoholic fatty liver disease (NAFLD) has increased drastically due to the global obesity pandemic but at present there are no approved therapies. Here, we aimed to revert high‐fat ...
