Evaluation Cyclopamine 11-deoxojervine of gene expression by quantitative reverse transcription PCR Total RNwas prepared from mdx4cTmuscles homogenized under liquid nitrogen by pestle and mortar. Means of cDNgeneration and RNisolation were in accordance with manufacturers protocols using reverse transcriptase as previ ously described. RNwas reverse tran scribed utilising the Omniscript RT Kit. For reverse transcription PCR, 10 ng cDNwas coupled with SYBR Green subsequent published situations and primer sequences for S1P related genes by Grabski et al. and by Au et al. for 18S. Practical investigation, myography Animals handled with THI or PBS viIP injec tion as aforementioned for 14 days were examined be tween 1 and 4 days after the final day of injection. Ahead of euthanasianimals were anesthetized with 0. 5 mgg weight avertin diluted in PBS. EDLs were then ex cised and equilibrated in Ringers solution with 95% O25% CO2 for minimum of 15 mi nutes before stimulation. For examination of direct S1P administration, EDL muscles from uninjured and untreated 3. 5 MO guy mdx were incubated with oxygenated Ringers solution containing 10 uM S1P or vehicle for fifteen Gene expression minutes prior to stimulation. All useful experiments were carried out with buffer solutions at 25 C under continuous oxygenation. Myography was conducted using 820S myograph and datwas recorded using PowerLab 430 acquisition system with LabChart Pro pc software v7. 3. 1. Stimulations were conducted with S88X dual systems. Muscles were stimulated to ascertain maximum fiber size and voltage at which maximum tetanic force was measured at 120 Hz using 4. 15 ms pulses within 450 ms train length. Force frequency was performed using the exact same pulse duration at 10, 20, 40, 60, 80, 100 and 120 Hz, as outlined in the x axis of Figure 3B. Specific force was calculated as previously described by normalizing for the muscle cross sectional area. CSis the quotient of dry muscle mass over Lo, that will be understood to be the product SL-01 of Lf with mammlian muscle density and the fiber size ratio. Measurement of S1P in mouse tissue S1P was quantified in tissue after homogenization and extraction applying fluid chromatography tandem mass spectrometry. Tissue was pulverized in liquid nitrogen applying mortar and pestle. Gathered tis sue was considered and an internal standard was added at 1 pmol mg tissue. Tissue was then vortexedextracted in 16 vol umes of acetonitrile,water for 10 mi nutes at room-temperature. Supernatants were collected after centrifugation and disadvantage centrated to dryness using SpeedVac Concentrator. Pellets were re-suspended in methnol to determined concentration of 0. 05 uM C17 base D erythro sphingosine 1 phosphate. Then 10 ul was analyzed by LC MSMS applying C17 base D erythro sphingosine 1 phosphate plus C18 base D erythro sphingosine 1 phosphate as standard.
