We have previously reported that astaxanthin (ASTX), a xanthophyll carotenoid, lowers plasma total cholesterol and TAG concentrations in<jats:italic>apoE<\/jats:italic>knockout mice. To investigate whether ASTX supplementation can prevent the development of NAFLD in obesity, male C57BL\/6J mice (<jats:italic>n<\/jats:italic>8 per group) were fed a high-fat diet (35\u00a0%, w\/w) supplemented with 0, 0\u00b7003, 0\u00b701 or 0\u00b703\u00a0% of ASTX (w\/w) for 12 weeks. The 0\u00b703\u00a0% ASTX-supplemented group, but not the other groups, exhibited a significant decrease in plasma TAG concentrations, suggesting that ASTX at a 0\u00b703\u00a0% supplementation dosage exerts a hypotriacylglycerolaemic effect. Although there was an increase in the mRNA expression of fatty acid synthase and diglyceride acyltransferase 2, the mRNA levels of acyl-CoA oxidase 1, a critical enzyme in peroxisomal fatty acid \u03b2-oxidation, exhibited an increase in the 0\u00b703\u00a0% ASTX-supplemented group. There was a decrease in plasma alanine transaminase (ALT) and aspartate transaminase (AST) concentrations in the 0\u00b703\u00a0% ASTX-supplemented group. There was a significant increase in the hepatic mRNA expression of nuclear factor erythroid 2-related factor 2 and its downstream genes, which are critical for endogenous antioxidant mechanism, in the 0\u00b703\u00a0% ASTX-supplemented group. Furthermore, there was a significant decrease in the mRNA abundance of<jats:italic>IL-6<\/jats:italic>in the primary splenocytes isolated from the 0\u00b703\u00a0% ASTX-supplemented group upon lipopolysaccharide (LPS) stimulation when compared with that in the splenocytes isolated from the control group. In conclusion, ASTX supplementation lowered the plasma concentrations of TAG, ALT and AST, increased the hepatic expression of endogenous antioxidant genes, and rendered splenocytes less sensitive to LPS stimulation. Therefore, ASTX may prevent obesity-associated metabolic disturbances and inflammation.<\/jats:p>","DOI":"10.1017\/s0007114514002554","type":"journal-article","created":{"date-parts":[[2014,10,20]],"date-time":"2014-10-20T09:15:13Z","timestamp":1413796513000},"page":"1797-1804","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":77,"title":["Astaxanthin
