Outline of Final Research Achievements |
We examined redox dynamics, bile acid composition and mutagenicity of bile obtained from biliary tract cancer patients. Furthermore, miRNAs contained in exosomes purified from bile were analyzed. Bile obtained from biliary tract cancer patients contained significantly more oxidized glutathione. Bile acids in the bile of patients with biliary tract cancer were found to contain a lot of secondary bile acids. The mutagenicity by the umu method was negative for all tested bile. Exosomes in the bile could not be stably collected by the known methods. We have developed a novel method to reproducibly extract exosomes from bile. Candidate miRNAs specific for biliary tract cancer were identified.
