Sphinganine 1 phosphate management We have demonstrated previously that sphinganine 1 phosphate produced dose dependent protection against liver and kidney injury after liver IR with the top protection observed Decitabine with the dose of 0. 1 mg/kg i. v. before reperfusion and 0. 2 mg/kg s. c. 2 hrs after reperfusion. In this study, sphinganine 1 phosphate was dissolved in warm methanol and the aliquots were stored at 20 C. The solution was evaporated under nitrogen immediately before use, and the powder redissolved in like a carrier 4 mg/mL fatty acid free bovine serum albumin solution as described by Van Brocklyn et al.. The sphinganine 1 phosphate dose that produced the maximum liver and kidney protection was directed at mice in this study. Vehicle treated mice received injections of 0. 4% fatty-acid free BSA. We also examined whether one injection of sphinganine 1 phosphate also could give liver and kidney safety after liver IR injury. In independent cohorts of mice, just one dose of sphinganine 1 phosphate was given immediately before or 2 hrs after reperfusion of the liver. In yet another cohort of mice, we also gave a Infectious causes of cancer measure of S1P to test whether S1P also provided kidney and liver safety. Our preliminary data showed that sphinganine 1 phosphate, S1P or car injection alone in sham operated mice had no effect on any one of the injury parameters tested in the liver or in the kidney. Plasma ALT exercise and creatinine level The plasma ALT activities were measured using the Infinity ALT assay kit according to the manufacturers instructions. Lcd creatinine was measured by an enzymatic creatinine reagent set based on the manufacturers instructions. This method of creatinine description largely removes the interferences from mouse plasma chromagens Avagacestat popular for the Jaffe method. Deciding S1P receptor subtype involved in sphinganine 1 phosphate and S1Pmediated renal and hepatic protection after liver IR To determine the S1P receptor subtype involved in sphinganine 1 phosphate and S1Pmediated renal and hepatic protection after liver IR, rats were treated with a selective S1P1, S1P2 or S1P3 receptor antagonist 20 min. before sphinganine 1 phosphate or S1P treatment. In separate cohorts of mice, we also treated mice using the selective S1P1 receptor agonist SEW 2871 in lieu of sphinganine 1 phosphate 30-min. prior to liver ischemia. The amounts of S1P1 receptor antagonists and SEW 2871 were obtained from previous in vivo studies. siRNA preparation and distribution to rats in vivo A chemically synthesized 21 nucleotide siSTABLE sequences particular for S1P1 receptors were tailor made and obtained from Dharmacon Research in 2? Annealed, hydroxyl, desalted and dialyzed duplex form for in vivo use. The siSTABLE can be a revised siRNA with improved resistance against nuclease degradation and improved silencing period in vivo. The double stranded sequence for S1P1 receptor siRNA was 5? CCTGTGACATCCTGTACAA 3?.
