Fig. 4 Supplemental 1 HTR2C promoted EMT-mediated metastatic dissemination of poorly metastatic human cancer cells in a zebrafish xenotransplantation model. (A) Quantification analyses of western blotting bands in Figure 4C. The analyses were performed by ImageJ. Signal strength of bands of E-cadherin, EpCAM, N-cadherin, vimentin, ZEB1, and HTR2C was normalized by that of GAPDH. (B) Representative images of dissemination patterns of MCF7 cells expressing either the control vector (top left, middle left, bottom left) or HTR2C (top right, middle right, bottom right) in a zebrafish xenotransplantation model.
