Hypothalamic malonyl-CoA and the control of food intake.
Jupiter, United States. In Physiol Behav, 2013
Malonyl-CoA inhibits the acyltransferase activity of carnitine palmitoyltransferase-1 (CPT-1), and CPT-1 was considered as a downstream effector in hypothalamic malonyl-CoA effect on feeding.
Companion Animals Symposium: nutrigenomics: using gene expression and molecular biology data to understand pet obesity.
Urbana, United States. In J Anim Sci, 2013
Diets including prebiotics, green tea extract, or increased concentrations of protein have been shown to modify the expression of several genes related to glucose and lipid metabolism in adipose [e.g., uncoupling protein-2, carnitine palmitoyltransferase-1, PPARα, lipoprotein lipase (LPL), and glucose transporter 4] and skeletal muscle (e.g., PPARα and LPL) tissues.
Molecular mechanisms of hypolipidemic effects of curcumin.
Boston, United States. In Biofactors, 2013
At the molecular level, mounting experimental evidence suggests that curcumin may act chemically as scavenger of free radicals and/or influences signal transduction (e.g., Akt, AMPK) and modulates the activity of specific transcription factors (e.g., FOXO1/3a, NRF2, SREBP1/2, CREB, CREBH, PPARγ, and LXRα) that regulate the expression of genes involved in free radicals scavenging (e.g., catalase, MnSOD, and heme oxygenase-1) and lipid homeostasis (e.g., aP2/FABP4, CD36, HMG-CoA reductase, and carnitine palmitoyltransferase-I (CPT-1)).
Hypothalamic fatty acid metabolism mediates the orexigenic action of ghrelin.
A Coruña, Spain. In Cell Metab, 2008
Here, we use pharmacological and genetic approaches to demonstrate that the physiological orexigenic response to ghrelin involves specific inhibition of fatty acid biosynthesis induced by AMP-activated protein kinase (AMPK) resulting in decreased hypothalamic levels of malonyl-CoA and increased carnitine palmitoyltransferase 1 (CPT1) activity.
