The cytotoxicity of the asparaginase gene expression and the chemotherapy is additive in PC9 and A549 cells. The cell proliferation assays were demonstrated under the treatments of (a) cisplatin (5.0 µM) in PC9 cells and (b) doxorubicin (0.25 µg/mL) in A549 cells after the transfection of pSB-ASNase and SB100. *p < 0.05 and **p < 0.001. MPT: T + PEI-absorbed MSN (T: pSB-ASNase and SB100).
