Rib and Eve induced apoptosis in Rb WT and Rb KD MCF-7 cell lines. Rb WT and Rb KD MCF-7 cell lines were treated with Rib and Eve, 10/15 μg/ml, 1:1.5ratio, alone and in combination, for 72 h. Flow cytometry was performed by Annexin V and PI double-staining. Data represent the percentage of PI and/or Annexin V positive cells and are representative of one of three separate experiments
