Hypothalamic endocannabinoids inversely correlate with the development of diet-induced obesity in male and female mice
(American Society for Biochemistry and Molecular Biology, 2019-07)
The endocannabinoid (eCB) system regulates energy homeostasis and is linked to obesity development. However, the exact dynamic and regulation of eCBs in the hypothalamus during obesity progression remain ...
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, ...
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 ...
Increased infammation, oxidative stress and mitochondrial respiration in brown adipose tissue from obese mice
(Springer Nature, 2017-11-22)
Obesity is associated with severe metabolic diseases such as type 2 diabetes, insulin resistance, cardiovascular disease and some forms of cancer. The pathophysiology of obesity-induced metabolic diseases ...
CPT1C in the ventromedial nucleus of the hypothalamus is necessary for brown fat thermogenesis activation in obesity
(Elsevier, 2019-01)
Objective: Carnitine palmitoyltransferase 1C (CPT1C) is implicated in central regulation of energy homeostasis. Our aim was to investigate whether CPT1C in the ventromedial nucleus of the hypothalamus ...
CPT1C promotes human mesenchymal stem cells survival under glucose deprivation through the modulation of autophagy
(Nature Research, 2018-05-03)
Human mesenchymal stem cells (hMSCs) are widely used in regenerative medicine. In some
applications, they must survive under low nutrient conditions engendered by avascularity. Strategies to
improve ...
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 ...
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 ...
