P-cadherin is co-expressed with GLUT1 and CAIX in basal-like breast cancer cell lines. By flow cytometry analysis, we observed that the 20% of cells with the highest and lowest P-cadherin expression presented highest and lowest, respectively, expression of GLUT1 and CAIX (A). When cells were sorted by P-cadherin expression, lysed and analyzed in SDS-PAGE, the same result was observed concerning the high and low expression of GLUT1 and CAIX (B). On the other hand, 20% of cells with the highest and lowest levels of GLUT1 and CAIX (C and D, respectively) expression also presented highest and lowest P-cadherin expression.
