8、ty, non-small cell lungcancer and MM cell lines are simultaneously treated for 72 hours with BTZ and CR4056. Cells are exposedto the IC50 of BTZ, estimated in the cytotoxicity study, with or without three concentrations of CR4056 (3, 10,and 30 M). The incubations with CR4056 alone (3, 10, and 30 M)
