Fig. 5From: High expression of Claudin-2 in esophageal carcinoma and precancerous lesions is significantly associated with the bile salt receptors VDR and TGR5TGR5 and VDR expression in esophagus. a TGR5 is moderately expressed in whole squamous mucosa. Focal extensive TGR5 expression is present in the basal membrane. b TGR5 expression is located at cell membrane and distributes the whole glands in BE case. c VDR is not expressed in squamous mucosa. d VDR expression is located at cell membrane and cytoplasm, predominately in cell membrane and distributes the whole glands in HGD caseBack to article page
