"STUDY":{"STUDY_TITLE":"Isolated murine skeletal muscles utilize pyruvate over glucose for oxidation-Part 1","STUDY_TYPE":"Study of the different substrate by isolated skeletal muscle at room temperature via C-13 isotopomer analysis","STUDY_SUMMARY":"Preclinical studies of muscle contractile function often employ ex vivo preparations of the soleus and/or extensor digitorum longus (EDL) muscles which are relatively easy to prepare and represent slow and fast fiber properties, respectively. Therefore, the current study sought to examine the utility of this preparation for understanding the metabolic fuel utilization in isolated resting mouse muscles at room temperature. 13C-labeling in both muscle types was performed using three fuels: glucose, pyruvate, and acetate, followed by NMR-based metabolomics analyses. Incubating 13C-labeled substrates in the isolated skeletal muscles makes it possible to examine TCA cycle flux and substrate selection by these muscles.","INSTITUTE":"University of Florida","DEPARTMENT":"Applied Physiology and Kinesiology","LABORATORY":"Rm 42 and Rm 43","LAST_NAME":"Khattri","FIRST_NAME":"Ram","ADDRESS":"1864 Stadium RD, Gainesville, FL, 32611, USA","EMAIL":"rbk11@ufl.edu","PHONE":"3307856045","NUM_GROUPS":"4","TOTAL_SUBJECTS":"18","STUDY_COMMENTS":"Southeastern Center for Integrated Metabolomics (SECIM) (ERB), NIH AR U54 AR052646 (Physiological Assessment Core, ERB), and Wellstone Muscular Dystrophy Cooperative Research Center Grant (NIAMS: U54AR052646/P50 AR052646).

"SAMPLEPREP":{"SAMPLEPREP_SUMMARY":"Perchloric acid (PCA) or acetonitrile:isopropanol:water (3:3:2) extractions were performed for all samples to isolate metabolites. The latter method was more efficient in sample recovery due to the reduced number of steps in the procedure but did not affect the proportion of metabolites. For PCA extraction, isolated muscle samples were homogenized with a FASTPREP-24 (MP Biomedicals, Solon, Ohio, USA) with 6% (v/v) ice cold PCA and centrifuged with 13.2 K rpm at 4 oC. The solid muscle portion was washed again with the 6% (v/v) ice cold PCA followed by centrifugation (13.2 K rpm) at 4 oC. The supernatant (combined) obtained was further neutralized with 5M potassium hydroxide and centrifuged again maintaining 13.2 K rpm speed at 4 oC. The resulting supernatants were then lyophilized (Thermo-Scientific, Dallas, USA). The pH of the dried powder was adjusted to 7.2 after dissolving it in 200 μL of ultra-pure water using 1M sodium hydroxide and 1 M hydrochloric acid. The pH-adjusted solution was further centrifuged, the resulting supernatant was dried and the powder was used to prepare the NMR sample. For acetonitrile:isopropanol:water extraction, homogenization of isolated muscle samples was carried out in 1 mL acetonitrile:isopropanol:water (3:3:2, v:v:v) ice cold mixture with a FASTPREP-24 (MP Biomedicals, Solon, Ohio, USA) and centrifuged at 4 oC in separate vials. Resultant supernatants were further lyophilized till dryness (Thermo-Scientific, Dallas, USA). The dried powder was further dissolved in 1 mL of Acetonitrile:Water (1:1, v:v) mixture, vortexed well for ~5 minutes. The resultant solution was further centrifuged, the supernatant obtained was further dried and the powder was used to prepare the NMR sample. The centrifugation speed for each step used was 13.2K rpm. Each NMR sample consisted of 50 mM phosphate buffer (pH 7), 2 mM EDTA, 0.02% of NaN3 with 0.5 mM of DSS as a standard internal reference in deuterated environment. 1H NMR spectra were taken at 25oC using a 600 MHz Bruker Avance II Console equipped with a TCI CryoProbe that utilized Bruker Topspin 4 software (Bruker BioSpin Corporation, Billerica, MA, USA). The first slice of a NOESY pulse sequence (noesypr1d) was used to acquire proton NMR. Fractional enrichment for glutamate, lactate and alanine were determined using 13C decoupling ON/OFF 1H proton spectra as well as 1D NOESY spectra. To determine enrichements, a standard zgig pulse sequence was adapted to allow 13C decoupling during the acquistion period (1.36 s) to remove the satellites. Total enrichment was measured by taking a ratio of the metabolite peak heights in the decoupling on/off experiments. NOESY spectra were collected with a 1 s relaxation delay (d1), and a 4 s acqusition time (at), in accordance with Chenomx recommendations for producing quantitative estimates of concentration. Using the Chenomx quantification and the fractional enrichments, a final concentration of the metabolites was calculated. Conventional 1H decoupled 13C spectra were acquired using a 600 MHz Agilent with a specially designed 1.5 mm superconducting (HTS) probe at 30oC.","SAMPLEPREP_PROTOCOL_FILENAME":"Isolated_muscle_Procedures.docx","PROCESSING_METHOD":"Lyophilization and Homogenization","PROCESSING_STORAGE_CONDITIONS":"-80℃","EXTRACTION_METHOD":"Perchloric acid (PCA) or acetonitrile:isopropanol:water (3:3:2) extractions","EXTRACT_STORAGE":"-80℃","SAMPLE_RESUSPENSION":"In 35 microliter of 50 mM phosphate buffer (pH 7.2) with 2 mM EDTA, 0.5 mM DSS and 0.2% sodium azide for aqueous phase samples.","SAMPLE_SPIKING":"0.5 mM of DSS for aqueous phase samples"},
