| Outline of Final Research Achievements |
From the immunohistochemical analyses, SOX17 expression was significantly lower in gall bladder epitheliums of a cluster of biliary atresia (BA) patients compared with that of other diseases. SOX9 expression was consistent in BA patients and other diseases. BA patients were classified according to the high/low expression of SOX17, and patients with low SOX17 expression were relatively younger than patients with high SOX17 expression. There were no significant differences in clinical appearances between two clusters.
And also, glandular structure was increased in the gall bladder epithelium of BA patients compared to other patients, which was consistent with the feature of SOX17 haplo-defficiency mice.
