Owing to the worldwide epidemic of obesity, and the popularity of diets rich in sugar and saturated fat, nonalcoholic fatty liver disease (NAFLD) is increasingly common; it is usually associated with insulin resistance, and may be considered a component of the metabolic syndrome. The pathologies which can complicate hepatic steatosis--steatohepatitis, cirrhosis, and hepatic cancer--appear to result from an interaction of hepatic lipid overload and hepatic oxidative stress. It is therefore proposed that comprehensive regimens which effectively target each of these precipitating factors should achieve the best therapeutic benefit in NAFLD. Appropriate weight loss, and a diet low in saturated fat, glycemic index, and added sugars, should decrease hepatic lipid load. Measures which enhance adipocyte insulin sensitivity--such as pioglitazone, astaxanthin, and spirulina--may also be helpful in this regard, as may agents that boost hepatocyte capacity for fatty acid oxidation, such as metformin, carnitine, hydroxycitrate, long-chain omega-3 fats, and glycine. Astaxanthin and spirulina appear to have considerable potential for controlling the oxidative stress associated with NAFLD - the former because it may help to prevent the mitochondrial damage that renders mitochondria a key source of superoxide in this syndrome, the latter because it is exceptionally rich in phycocyanobilin, a phytochemical inhibitor of NAPDH oxidase. Other antioxidants which show some promise in this syndrome include high-dose folate, lipoic acid, melatonin, N-acetylcysteine, vitamin E, and taurine. Finally, treatment with salsalate, an inhibitor of IkappaB kinase-beta, has potential for blunting the adverse impact of hepatic steatosis on oxidative stress and inflammation.

Astaxanthin (AXT) is classified as a xanthophyll carotenoid compound which have broader functions including potent antioxidant, anti-inflammatory and neuroprotective properties. Considerable researches have demonstrated that AXT shows preventive and therapeutic properties against for Diabetes, Osteoarthritis and Rheumatoid Arthritis. However, the protective effect of AXT on liver disease has not yet been reported. In this study, we investigated effects of AXT on ethanol-induced liver injury in chronic plus binge alcohol feeding model. The hepatic steatosis and inflammation induced by ethanol administration were alleviated by AXT. Serum levels of aspartate transaminase and alanine transaminase were decreased in the livers of AXT administrated group. The ethanol-induced expression of cytochrome P450 2E1 (CYP2E1), pro-inflammatory proteins, cytokines, chemokines and reactive oxygen species (ROS) levels were also reduced in the livers of AXT administrated group. Moreover, ethanol-induced infiltration of neutrophils was decreased in the livers of AXT administrated group. Docking model and pull-down assay showed that AXT directly binds to the DNA binding site of STAT3. Moreover, AXT decreased STAT3 phosphorylation in the liver of AXT administration group. Therefore, these results suggest that AXT could prevent ethanol-induced hepatic injury via inhibition of oxidant and inflammatory responses via blocking of STAT3 activity.

Type 2 diabetes mellitus (T2DM), which is characterized by insulin resistance and relative insulin insufficiency, has become the most common chronic metabolic disease threatening global health. The preferred therapies for T2DM include lifestyle interventions and the use of anti-diabetic drugs. However, considering their adverse reactions, it is important to find a low-toxicity and effective functional food or drug for diabetes prevention and treatment. Astaxanthin is a potent antioxidant carotenoid found in marine organisms has been reported to prevent diet-induced insulin resistance and hepatic steatosis. To investigate the anti-diabetic effects of astaxanthin, male Wistar rats were fed a high-energy diet for 4 weeks, followed by a low dose streptozotocin (STZ) injection to induce the diabetes model, and the rats were then fed an astaxanthin-containing diet for another 3 weeks. Astaxanthin significantly decreased blood glucose and total cholesterol (TC) levels, and increased blood levels of high density lipoprotein cholesterol (HDL-C) in STZ-induced diabetic rats in a dose dependent manner. These results were associated with increased expression of insulin sensitivity related genes (adiponectin, adipoR1, and adipoR2) in vivo, thereby attenuating STZ-induced diabetes. In addition, we also compared the anti-diabetic effects of astaxanthin and monacolin K, which has been reported to downregulate hyperlipidemia and hyperglycemia. The results revealed that astaxanthin and monacolin K showed similar anti-diabetic effects in STZ-induced diabetic rats. Therefore, astaxanthin may be developed as an anti-diabetic agent in the future.
