Cell proliferation assay of NCI-H295R treated with bortezomib (A), ouabain (B), methotrexate (C), and pyrimethamine (D). Selected effective concentrations of bortezomib, ouabain, methotrexate, and pyrimethamine from cell proliferation assay of NCI-H295R were validated in SW-13 (E). The error bar indicates the ranges of cell numbers. * p value <0.05 but ≥ 0.01, ** p value < 0.01.
