Anti-cancer activity of PdPT in vitro. (A) A549, NCI-H1299, A549/DDP and BEAS-2B cells were exposed to indicated concentration of PdPT for 24 or 48 h. Cell viability was detected by MTS assay (n = 3; *P < 0.05). (B) A549, NCI-H1299, A549/DDP and BEAS-2B cells were exposed to indicated CDDP for 24 or 48 h. Cell viability was detected by MTS assay (n = 3; *P < 0.05). (C,D) A549 and NCI-H1299 cells were treated with indicated PdPT for 24 h. Apoptotic cells were detected with Annexin V-FITC and PI double stain followed by flow cytometry. (E) In parallel, fluorescence microscope were used to monitor the levels of Annexin V- or PI-positive cells.
