Study TitleMetabolic landscape remodeling in dystrophic muscle through glucocorticoid steroid regimens
Study SummaryDuchenne muscular dystrophy is caused by genetic defects in the gene encoding dystrophin and leads to progressive muscle degeneration. Glucocorticoid steroids are current mainstay pharmacological regimen to decrease muscle inflammation and prolong the ambulatory period in these patients, but daily intake of glucocorticoids like prednisone and deflazacort causes adverse side effects like osteoporosis, adrenal suppression, insulin resistance and obesity. Intermittent steroid dosing has been proposed as alternative to maintain benefits and limit side effects, but a detailed understanding of the mechanisms underpinning the regimen-specific effects in muscle is still missing. Here we explore how once-daily versus once-weekly prednisone (4 week-long treatment) affect the metabolomic landscape in mdx mouse muscle (genetic model of Duchenne muscular dystrophy; DBA/2J background) through metabolomics profiling.

Chromatography ID:CH001522
Chromatography Summary:200ul of 50% Acetonitrile were added to the tube for reconstitution following by overtaxing for 1 min. Samples solution were then centrifuged for 15 min @ 20,000g, 4°C. Supernatant was collected for LC-MS analysis for Hydrophilic Metabolites Profiling as follows. Samples were analyzed by High-Performance Liquid Chromatography and High-Resolution Mass Spectrometry and Tandem Mass Spectrometry (HPLC-MS/MS). Specifically, system consisted of a Thermo Q-Exactive in line with an electrospray source and an Ultimate3000 (Thermo) series HPLC consisting of a binary pump, degasser, and auto-sampler outfitted with a Xbridge Amide column (Waters; dimensions of 4.6 mm × 100 mm and a 3.5 µm particle size). The mobile phase A contained 95% (vol/vol) water, 5% (vol/vol) acetonitrile, 20 mM ammonium hydroxide, 20 mM ammonium acetate, pH = 9.0; B was 100% Acetonitrile. The gradient was as following: 0 min, 15% A; 2.5 min, 30% A; 7 min, 43% A; 16 min, 62% A; 16.1-18 min, 75% A; 18-25 min, 15% A with a flow rate of 400 μL/min.
