Fig. 1From: Loss of tumor suppressor menin expression in high grade cholangiocarcinomasThe expression level of menin is inversely related to the grade of the CCA. The images in this figure were obtained from the immunohistochemical staining of CCA tumors in the microarray. Immunohistochemical staining of menin showing the range of IHC scores. A Menin IHC = 3, grade I. B Menin IHC = 2, grade I. C Menin IHC = 1, grade II. D Menin IHC = 0, grade III. Immunohistochemical staining of menin and H&E staining. E, F Menin IHC = 3, Grade I. G, H Menin IHC = 0, Grade III. Arrows indicate menin-immunoreactivity. Bar = 500 μmBack to article page
