Expression of FXR in cholangiocarcinoma tissues from patients. Tissues from 26 patients and 10 normal controls were obtained. Immunostaining for FXR expression was done. A, negative control for immunostaining. B, FXR expression in normal biliary ducts. C, FXR expression in cholangiocarcinoma tissues. The FXR expression was quantitated according to staining intensity and reported as mild (+), moderate (++) and strong (+++), respectively. The results were summarized in the table.
