Metabolic and Tissue-Specific Regulation of Acyl-CoA Metabolism
Acyl-CoA formation initiates cellular fatty acid metabolism. Acyl-CoAs are generated by the ligation of a fatty acid to Coenzyme A mediated by a large family of acyl-CoA synthetases (ACS). Conversely, acyl-CoAs can be hydrolyzed by a family of acyl-CoA thioesterases (ACOT). Here, we have determined the transcriptional regulation of all ACS and ACOT enzymes across tissues and in response to meta...
متن کاملMetabolic Regulation of Histone Acetyltransferases by Endogenous Acyl-CoA Cofactors.
The finding that chromatin modifications are sensitive to changes in cellular cofactor levels potentially links altered tumor cell metabolism and gene expression. However, the specific enzymes and metabolites that connect these two processes remain obscure. Characterizing these metabolic-epigenetic axes is critical to understanding how metabolism supports signaling in cancer, and developing the...
متن کاملMetabolic Regulation of Invadopodia and Invasion by Acetyl-CoA Carboxylase 1 and De novo Lipogenesis
Invadopodia are membrane protrusions that facilitate matrix degradation and cellular invasion. Although lipids have been implicated in several aspects of invadopodia formation, the contributions of de novo fatty acid synthesis and lipogenesis have not been defined. Inhibition of acetyl-CoA carboxylase 1 (ACC1), the committed step of fatty acid synthesis, reduced invadopodia formation in Src-tra...
متن کاملRegulation of acetyl-coA carboxylase: properties of coA activation of acetyl-coA carboxylase.
Acetyl-CoA carboxylase [acetyl-CoA:carbon-dioxide ligase (ADP-forming), EC 6.4.1.2] is activated by physiological concentrations of CoA. The CoA concentration dependency of this activation is sigmoidal; below 60 microM there is little or no activation, but the activation observed between 60 and 120 microM indicates that small changes in the concentration of CoA can cause significant changes in ...
متن کاملMultivalent feedback regulation of HMG CoA reductase, a control mechanism coordinating isoprenoid synthesis and cell growth.
The availability of compactin (ML-236B), a potent competitive inhibitor of 3-hydroxy-3-methylglutaryl Coenzyme A reductase, has permitted the demonstration of a hitherto unsuspected aspect of mevalonate metabolism and isoprenoid synthesis in cultured mammalian cells. 3-Hydroxy-3-methylglutaryl Coenzyme A reductase, the enzyme that synthesizes mevalonate, appears to be regulated through a multiv...
