| Outline of Final Research Achievements |
Transaminase, total bilirubin, and bile acid levels were elevated after 24 hours in the LPS + 70% hepatectomy group compared with the 70% hepatectomy group. In the microarray analysis, the levels of organic anion transporting polypeptides (Oatps), which are sinusoidal side transporters that extract the bilirubin in the blood, and sodium taurocholate cotransporting polypeptide (Ntcp) that uptakes the bile acids from the blood, and ATP binding cassette protein C2 (Mrp2) that excrete the bile acids into bile duct, tended to decrease compared with the 70% hepatic resection group. In the RT-PCR, the similar decrease trend was confirmed. This study suggested that during liver regeneration in the case of infection after hepatectomy versus normal hepatectomy, the organic anion transporter impairments on the hepatocyte membrane might be enhanced and hyperbilirubinemia would be prolonged.
