IC50 values were calculated for MLN0128 and TSA from each cell line following a 72 h cell viability assay. Values were calculated from at least six independent wells from two independent experiments. Overexpression status for ER, PR, and HER2 is indicated along with PIK3CA mutation status and PTEN loss
