Figure 3.
Cell viability of MDA-MB-231 cells treated with OP at indicated doses in combination with 1 μM of either cisplatin, 5-FU, paclitaxel, gemcitabine, or tamoxifen using the WST-1 assay.
Notes: Cells were incubated in 96-well plates (5,000 cells/well) and allowed to adhere for 24 hours in 1× DMEM media containing 10% FCS. The media were replaced with fresh DMEM media containing 5% FCS with or without various concentrations of OP or chemodrugs for 24, 48, and 72 hours as predetermined optimally. Cell viability was expressed as a percent of control ± SEM of three independent experiments. Statistical analysis was carried out using GraphPad Prism, and results were compared by unpaired t-test.
Abbreviations: 5-FU, 5-fluorouracil; DMEM, Dulbecco’s Modified Eagle’s Medium; FCS, fetal calf serum; OP, oseltamivir phosphate; SEM, standard error of the mean.
