Figure 2From: Proteomic analysis of acquired tamoxifen resistance in MCF-7 cells reveals expression signatures associated with enhanced migrationMCF-7-TamR cells are resistant to tamoxifen in clonogenic assays. A. Effect of tamoxifen on colony formation of MCF-7-TamR and MCF-7-control. Number of colonies formed in resistant and sensitive cell lines was plotted as a function of treatment (DMSO and tamoxifen). B. Representative colony images of the resistant and sensitive cells.Back to article page
