Afterwards, the cells were thawed, homogenized using homogenizer (ULTRA-TURRAX, Rose Scientific, Edmonton, Canada), shaken for 60 min, and centrifuged at 13,000 g for 10 min at 4°C. Fat content in tissues of C57BL/6J (B6) and B6.A-(rs3676616-D10Utsw1)/KjnB6 (B6.A) mice after 12 weeks of high fat diet (HFD) feeding. and A.R.). HHS A. Truett, J. ), Brendan M. Gabriel (B.M.G. Extraction of tissue fat was carried out using the Soxhlet method. The generalized form is also known as 5 … For the CS assay, the molar extinction coefficient used was 13 600 M−1 cm−1 for CoA-5,5′-thiobis(2-nitrobenzoic acid) at 412 nm. 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. CS from a porcine heart was used as a standard (C3260-200UN, Sigma-Aldrich Company Ltd, Gillingham, Dorset, UK) for assay calibration. The chromosomal markers are also indicated. 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 grown on several different substrates, whereas other metabolite levels were similar in the two strains; and (c) under conditions for induction of the phosphotransferase system, the wild type exhibited at least twice as much phosphotransferase activity as the mutant strain. The CIT1 gene encoding mitochondrial citrate synthase was initially cloned following a screen for mRNAs enriched in polysomes bound to mitochondria (4). the irreversible condensation of acetyl coenzyme A (AcCoA) and oxaloacetate into citrate. The P deficiency-induced increase in NO production was inhibited by antagonists of NO synthase and xanthine oxidoreductase, suggesting the involvement of these enzymes in NO production. For HAD assay, the molar extinction coefficient used was 63,000 M−1 cm−1 for NADH at 340 nm. Would you like email updates of new search results? The standard free energy change (ΔG°’) for the citrate synthase re… C2C12 mouse muscle cells were used to investigate the effects of reduced CS activity on palmitate-induced lipotoxicity. 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. B. All the tests were two-tailed with the significance level set at . 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). The cells were then washed three times in PBS to remove all the excess dye. Analysis of covariance (ANCOVA), with body mass as a covariate, was applied to RMR, DEE, and MEI data. 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). GM3 synthase deficiency is a rare neurological disorder in which the brain does not develop normally. L.M.V., Y.A., A.L., and A.R. Proc Natl Acad Sci U S A. Then, lentivirus-delivered stable gene silencing was applied to knock down Cs expression in the cells [38]. Plasma insulin concentrations were measured in duplicates using the enzyme-linked immunosorbent assay (insulin ELISA, # nr 10-1247-01, Mercodia, Sweden) and the spectrophotometric plate reader (Synergy HT Multi-Mode Microplate Reader, BioTek, UK).
