For these experiments, 2 × 106 cells were seeded in six well plates coated with extracellular matrix gel (E6909, Sigma-Aldrich, MO, USA) and containing 2 ml of the growth medium. The area under curve for changes in blood glucose over time or blood glucose AUC was calculated using Prism 5.0 software. HHS The supernatants were taken and the protein concentration was measured using the Bradford assay. Then, lentivirus-delivered stable gene silencing was applied to knock down Cs expression in the cells . Iron deficiency resulted in a decrease in expression of iron containing proteins of the mitochondrial respiratory chain in muscle. Chang, “Phenotypic profile of SWR/J and A/J mice compared to control strains: possible mechanisms underlying resistance to obesity on a high-fat diet,”, V. Kus, T. Prazak, P.

Blood glucose was measured with a glucometer (ACCU-Chek Aviva, Roche, West Sussex, UK) using the whole blood samples taken from cut tail tips immediately before and at 15, 30, 60, and 120 min after the injection. 22.214.171.124 (previously 126.96.36.199)] exists in nearly all living cells and stands as a pace-making enzyme in the first step of the citric acid cycle (or Krebs cycle). Citrate synthase, a non-iron containing citrate cycle … Citrate synthase and long-chain fatty acyl-CoA dehydrogenase, used as markers for the citrate cycle and fatty acid oxidation pathways, were unaffected by the iron deficiency. Then, measurements of citrate synthase (CS) and β-hydroxyacyl-coenzyme (CoA) dehydrogenase (HAD) activity were carried out at room temperature of 21°C using the spectrophotometer (GENESYS 10 Bio UV-Vis, Thermo Fisher Scientific Inc., Waltham, MA, USA). Mice were anesthetized by inhalation of a mixture of isoflurane and oxygen for the duration of the scan (∼3 min). Afterwards Con shRNA and Cs shRNA cells were incubated in the media containing 5.5 mM glucose (G) and/or 0.8 mM palmitate (P). | Pseudoviruses were produced by cotransfecting HEK293 cells with a plasmid carrying shRNA and the Mission lentiviral packaging mix (SH001, Sigma–Aldrich) containing plasmids expressing viral packaging genes and a heterologous viral envelope gene. Increased activity of citrate synthase … Tissue fat mass was calculated by subtraction of dry mass of sample and thimble after and before extraction. The chromosomal markers are also indicated. We used shRNA (GCACCCAACATTTGAGTTATTCTCGAGAATAACTCAAATGTTGGGTGC) which targets the 3′untranslated region (UTR) of Cs mRNA (Cs shRNA) and control shRNA (Con shRNA) containing random sequence. It is the first step of the citric acid cycle, also known as the Krebs cycle.Glucose has previously been broken into … The extent of shRNA-mediated Cs knockdown was assessed using the real time RT-PCR and measurements of CS activity using the spectrophotometric CS assay on Cs shRNA and Con shRNA cells. The in-active proteins are caused by the autosomal recessive inheritance of defective … A citrate-synthase-deficient mutant had the following properties: (a) high constitutive levels of glyoxylate pathway enzymes on various substrates, while such levels were only found in the wild type when it was grown on acetate; (b) acetyl-CoA levels much higher than in the wild type … Oleate … Background Primary coenzyme Q10 (CoQ10) deficiency is rare. ), Kuwait Ministry of Health grant (to M.A.T. and S.R.G.

Truett, P. Heeger, R. L. Mynatt, A. By deleting RTG1, RTG3, or genes encoding citrate synthase, mtDNA instability was prevented in aco1Δ mutant cells. Glutathione synthetase deficiency is caused by alterations (mutations) in the GSS gene and is inherited in an autosomal recessive manner. The shRNA was delivered within the pLKO.1-puro vector containing the puromycin resistance marker. Repeated measures analysis of variance (ANOVA) was used in case of body weight (BW), body fat (BF), lean body mass (LBM), food intake (FI), mitochondrial enzyme activity, physical activity (PA), body temperature, and data on glucose tolerance. After incubation with a primary antibody, membranes were washed in TBS-T buffer and exposed for 2 h to HRP-conjugated secondary antibody (#7071) at 1 : 2000 dilution in the blocking buffer.

Pyruvate Dehydrogenase Complex Deficiency The PDH complex converts pyruvate, which is derived from the catabolism of glucose, to acetyl-CoA, which enters the TCA cycle at citrate … The mouse Cs intron spanning primers were designed using Universal Probe library software and purchased from Sigma-Genosys (forward primer: 5′-GGAAGGCTAAGAACCCTTGG-3′ and reverse primer: 5′-TCATCTCCGTCATGCCATAGT-3′) and the corresponding UPL probe (UPL probe #100) was used. NLM The supernatants were taken, the protein concentration was measured using the Bradford assay, and samples with equal protein concentration were made in Laemmli buffer as in our previous studies . Fasting levels of plasma lipids and insulin in C57BL/6J (B6) and B6.A-(rs3676616-D10Utsw1)/KjnB6 (B6.A) mice after 12 weeks of high fat diet (HFD) feeding. ), Catherine Hambly (C.H.

C2C12 muscle cells were treated either with control shRNA (Con shRNA) or Cs shRNA which targeted, Palmitate-induced lipotoxicity in C2C12 muscle cells (Cont). Blood samples were taken after 1 h of isotope equilibration to estimate initial isotope enrichments and were also collected from unlabelled animals to estimate the background isotope enrichments. Powered by netvibes. General linear models were used in the analysis. Three high-enrichment standards were analysed each day alongside the samples. Fat mass (FM) of mice was measured using dual energy X-ray absorptiometry (DEXA; PIXImus2 Series Densitometers with software version 1.46.007; GE Medical Systems Ultrasound and BMD, Bedford, UK). Previous studies of Arthrobacter pyridinolis indicated that during the first half of the growth cycle on D-fructose, the organism utilizes a respiration-coupled transport system and exhibits glyoxylate pathway activity; during the second half of the growth cycle, a phosphoenolypyruvate:D-fructose phosphotransferase system is used for transport and no glyoxylate pathway activity is found [Pelliccione et al. Induction of the phosphoenolpyruvate: hexose phosphotransferase system associated with relative anaerobiosis in an obligate aerobe. ), NHS Grampian Endowment Grant (no. J Bacteriol. The 1000 μL of reaction reagent included 20 μL of muscle homogenate. (b) Effect of palmitate exposure on the phosphorylation of PKB (Ser473) in Con shRNA and Cs shRNA cells. The membranes were washed with Tris buffered saline (TBS) containing 0.1% (vol/vol) Tween-20 (TBS-T buffer) before two hour incubation in the blocking buffer (5% (wt./vol) nonfat milk in TBS-T buffer). The deficiency is characterized clinically by salt-wasting, failure to thrive, and growth retardation. Citrate that moves from the mitochondria into the cytoplasm is converted by which enzyme into oxaloacetate and acetyl-CoA? Genotyping chromosome 10 in congenic B6.A-(rs3676616-D10Utsw1)/KjnB6 (B6.A) strain. Citrate synthase is an enzyme active in all examined cells, where it is most often responsible for catalyzing the first reaction of the citric acid cycle (Krebs Cycle or the tricarboxylic acid [TCA] cycle): the condensation of acetyl-CoA and oxaloacetate to form citrate.
