title: A novel soluble beta-glucan salecan protects against acute alcohol-induced hepatotoxicity in mice.
abstract: This investigation was designed to determine the effect of a novel soluble beta-glucan salecan on acute alcohol-induced hepatic injury in mice. Mice were given salecan (15 or 30 mg/kg) or PBS for 4 d. Ethanol (6 g/kg) was administered orally 1 h after the last injection. The animals were sacrificed at 10 h after alcohol administration. Pretreatment with salecan significantly ameliorated the hepatic damage induced by ethanol, as evidenced by markedly reduced serum aminotransferase activities and hepatocyte steatosis. Salecan administration remarkably alleviated the formation of thiobarbituric acid-reactive substances and counteracted glutathione depletion. The mRNA level of peroxisome proliferator activated receptor alpha, a major gene responsible for fatty acid oxidation, was significantly increased after salecan pretreatment. The expression of diacylglycerol acyltransferase 1, an important gene responsible for triacylglycerol synthesis, was markedly decreased after salecan was administrated. These findings suggest that salecan might represent a novel protective strategy against alcoholic liver injury.
