Dose- and time-dependent inhibition of viability in MDA-MB-231 cells by bromelain and cisplatin single treatment. The figure shown in a is the MTT assay results for bromelain at 24 and 48 h, with IC50 value for bromelain at 48 h is 4.10 µM. The figure shown in b is the MTT assay results for cisplatin at 24 and 48 h, with IC50 value for cisplatin at 48 h is 23.0 µM. The results are expressed as mean ± SD of three separate experiments
