The effect of pitavastatin-zoledronic acid combinations on cell death. (A) Dead cells were measured by trypan blue staining after 72 and 96 hr of exposure to the indicated drug concentration. (B) Relative cell viability was measured by celltiter-Glo assay (ATP) after 72 hrs exposure to the indicated drug concentration. In both assays, the results (mean ± SD; n = 3) were compared to the effect expected for an additive interaction calculated using the Bliss independence criterion (solid line for each drug combination) and determined using the measured effect of the individual drugs in each individual experiment. Results were significantly different from the expected Bliss effect where shown (*P < 0.05; ** < 0.01; *** < 0.001, paired t-test).
