BACKGROUND The pathogenesis of fatty liver is likely to depend on a complex interaction of environmental and genetic factors. We investigated a large-scale analysis of the association between microsomal triglyceride transfer protein (MTTP) and phosphatidylethanolamine N-methyltransferase (PEMT) polymorphism in alcoholic and nonalcoholic fatty liver disease.(More)
Gallbladder epithelial cells (GBEC) are exposed to high cholesterol concentrations in bile, and export cholesterol via an ATP-binding cassette (ABC) transporter-mediated pathway in vitro. These findings suggest that aberrant expression and/or function of ABC sterol transporters may be associated with cholesterol-related gallbladder diseases (CAGD). In this(More)
