Rib and Eve induced cytotoxicity in Rb WT and Rb KD MCF-7 cell lines. Cell viability was determined by MTT assay. Rb WT MCF-7 and Rb KD MCF-7 cells were treated for a 48 h and b 72 h with different concentrations of Ribociclib; c 48 h and d 72 h with different concentrations of Everolimus. Data shown are expressed as mean ± SE of three separate experiments. *p < 0.05 Rb WT MCF-7 vs Rb KD MCF-7
