Stearoyl-CoA desaturase (SCD) catalyzes the rate-limiting step in the biosynthesis of monounsaturated fatty acids. Mice with a targeted disruption of the SCD1 isoform have reduced body adiposity, increased energy expenditure, and up-regulated expression of several genes encoding enzymes of fatty acid beta-oxidation in liver. The mechanisms by which SCD deficiency leads to these metabolic change...
Excessive ethanol intakes have been reported to be linked liver diseases such as hepatitis and cancerrelated of ethanol. can lead the accumulation reactive oxygen species(ROS) depletion glutathione (GSH) in liver. Ethanol-induced oxidative stress substantiallyincreases peroxidation lipid decreases GSH levels human hepatocyte animal models.Ethanol contributes sterol regulating element-binding pr...
Fibroblast growth factor-1 (FGF1) and FGF19 have been shown to improve glucose metabolism in diabetic rodents, but how this occurs is unknown. Here to investigate the mechanism of action of these growth factors, we perform intracerebroventricular (i.c.v.) injections of recombinant FGF1 or FGF19 in an awake rat model of type 1 diabetes (T1D) and measure rates of whole-body lipolysis, hepatic ace...
The metabolic role of biotin in animals is as a prosthetic group in enzymes involved in carboxylation reactions. There are three enzymes of principal importance. Pyruvate carboxylase (PC; EC 6.4.1. I ) catalyses the conversion of pyruvate to oxaloacetate within the mitochondrion. Oxaloacetate is an intermediate in the biosynthesis of phosphoenol pyruvate and, ultimately, glucose. Thus, PC plays...
Impaired insulin-mediated suppression of hepatic glucose production (HGP) plays a major role in the pathogenesis of type 2 diabetes (T2D), yet the molecular mechanism by which this occurs remains unknown. Using a novel in vivo metabolomics approach, we show that the major mechanism by which insulin suppresses HGP is through reductions in hepatic acetyl CoA by suppression of lipolysis in white a...
Periportal and perivenous hepatocytes were isolated from rats subjected to different treatments that induce (starvation, cold exposure) or depress (refeeding after starvation) hepatic fatty acid oxidation. These experiments were designed to determine factors that may be involved in creating and maintaining the asymmetrical distribution of this metabolic pathway in the acinus of the liver. The u...
1. Methods are described for the extraction and assay of acetyl-CoA and of total acid-soluble and total acid-insoluble CoA derivatives in rat epididymal adipose tissue. 2. The concentration ranges of the CoA derivatives in fat pads incubated in vitro under various conditions were: total acid-soluble CoA, 0.20-0.59mm; total acid-insoluble CoA, 0.08-0.23mm; acetyl-CoA, 0.03-0.14mm. 3. An investig...
In skin fibroblasts grown from four children with a homozygous form of type II hyperlipoproteinemia, the feedback control of sterol synthesis and the inhibitory effect on hydroxymethylglutaryl (HMG) CoA reductase activity by serum or low density lipoprotein were present, though diminished compared with the effects in normal fibroblasts. Stimulation of HMG CoA reductase by insulin and inhibition...
