Immunohistochemical staining for KIAA1199, E-cadherin, N-cadherin and vimentin. (A). A1, A2: Positive KIAA1199 expression in CCA tissue. E1, E2: Negative KIAA1199expression in adjacent tissue. B1, B2: Negative E-cadherin expression in CCA tissue. F1, F2: Positive E-cadherin expression in adjacent tissue. C1, C2: Positive N-cadherin expression in CCA tissue. G1, G2: Positive Vimentin expression in CCA tissue. H1, H2: Negative Vimentin expression in adjacent tissue. (scale bar, 50 μm; magnification: ×200, ×400) (B) Western blot analysis of EMT signaling molecules (N-cadherin, E-cadherin and Vimentin) in KIAA1199 silenced Hucct1 cell line. (C) Western blot analysis of EMT signaling molecules ((N-cadherin, E-cadherin and Vimentin) in KIAA1199 overexpressed QBC939 cell line. Representative of three independent experiments.
