| 1 | Bile acids and sphingosine-1-phosphate receptor 2 in hepatic lipid metabolism显示文摘The liver is the central organ involved in lipid metabolism. Dyslipidemia and its related disorders, including non-alcoholic fatty liver disease(NAFLD), obesity and other metabolic diseases, are of increasing public health concern due to their increasing prevalence in the population. Besides their well-characterized functions in cholesterol homoeostasis and nutrient absorption, bile acids are also important metabolic regulators and function as signaling hormones by activating specific nuclear receptors, G-protein coupled receptors, and multiple signaling pathways. Recent studies identified a new signaling pathway by which conjugated bile acids(CBA) activate the extracellular regulated protein kinases(ERK1/2) and protein kinase B(AKT) signaling pathway via sphingosine-1-phosphate receptor 2(S1PR2). CBA-induced activation of S1PR2 is a key regulator of sphingosine kinase 2(Sph K2) andhepatic gene expression. This review focuses on recent findings related to the role of bile acids/S1PR2-mediated signaling pathways in regulating hepatic lipid metabolism. | Eric Kwong Yunzhou Li Phillip B.Hylemon Huiping Zhou | 2015 | Acta Pharmaceutica Sinica B2015，5，2： | 13 |
| 2 | Bile acids as global regulators of hepatic nutrient metabolism显示文摘Bile acids(BA)are synthesized from cholesterol in the liver.They are essential for promotion of the absorption of lipids,cholesterol,and lipid-soluble vitamins from the intestines.BAs are hormones that regulate nutrient metabolism by activating nuclear receptors(farnesoid X receptor(FXR),pregnane X receptor,vitamin D)and G protein-coupled receptors(e.g.,TGR5,sphingosine-1-phosphate receptor 2(S1PR2))in the liver and intestines.In the liver,S1PR2 activation by conjugated BAs activates the extracellular signal-regulated kinase 1/2 and AKT signaling pathways,and nuclear sphingosine kinase 2.The latter produces sphingosine-1-phosphate(S1P),an inhibitor of histone deacetylases 1/2,which allows for the differential up-regulation of expression of genes involved in the metabolism of sterols and lipids.We discuss here the emerging concepts of the interactions of BAs,FXR,insulin,S1P signaling and nutrient metabolism. | Phillip B.Hylemon Kazuaki Takabe Mikhail Dozmorov Masayuki Nagahashi Huiping Zhou | 2017 | Liver Research2017，1，1： | 3 |
