Moreover, the Na+-taurocholate cotransporting polypeptide (NTCP), responsible for bile acid (BA) uptake into hepatocytes, was identified as the functional cellular receptor mediating HBV entry. The aim of the study was to determine whether HBV alters the liver metabolic profile by employing HBV-infected and uninfected human liver chimeric mice. Humanized urokinase plasminogen activator\/severe combined immunodeficiency mice were used to establish chronic HBV infection. Gene expression profiles were determined by real-time polymerase chain reaction using primers specifically recognizing transcripts of either human or murine origin. Liver biopsy samples obtained from HBV-chronic individuals were used to validate changes determined in mice. Besides modest changes in lipid metabolism, HBV-infected mice displayed a significant enhancement of human cholesterol 7\u03b1-hydroxylase (human [h]<\/jats:bold>\n                      <jats:bold>CYP7A1<\/jats:bold>\n                      <jats:bold>; median 12-fold induction;<\/jats:bold>\n                      <jats:bold>P<\/jats:bold>\n                      <jats:bold>&lt; 0.0001), the rate-limiting enzyme promoting the conversion of cholesterol to BAs, and of genes involved in transcriptional regulation, biosynthesis, and uptake of cholesterol (human sterol-regulatory element-binding protein 2, human 3-hydroxy-3-methylglutaryl-coenzyme A reductase, and human low-density lipoprotein receptor), compared to uninfected controls.
