In A549 cells PF0 and siRNA-V combination revealed a moderate synergism at 6 and 12 nmol/l siRNA-V concentration, and slight synergism at 18 nmol/l, with CI values between 0.62 and 0.88 (Figure 7a, Table 1). In H460 cells, PF0 and siRNA-V showed moderate synergism at 4 nmol/l siRNA-V concentration, synergism at 6 nmol/l, and slight synergism at 12 nmol/l, with CI values between 0.51 and 0.81 (Figure 7b, Table 1). |

实验结果 |
A549 and H460 cells also showed significant (P < 0.05) differences between PF0 (200 nmol/l for A549 and 2,000 nmol/l for H460) treated and nontreated cells (Figure 5c,d). A549 cells showed that after 16 hours of 50 nmol/l siRNA-V and 200 nmol/l PF0 treatment wound closure was 18.48 ± 1.60% comparing with 47.24 ± 2.09 of the control treated cells. |

实验结果 |
The reduction was more remarkable after PF0 was combined with siRNA-V showing a significant (P < 0.05) decrease in colony formation to a 29.83 ± 8.11% as compared with control. For A549 cells, the combination resulted in a significant (P < 0.05) colony formation reduction when compared with PF0 treatment (Figure 4c). The relative colony-forming ability of H460 cells was reduced after PF0 treatment to 61.86 ± 20.48% and after siRNA-V treatment to 73.21 ± 1.97% as compared with controls (Figure 4b,d). PF0 and siRNA-V combination showed a significant (P < 0.05) decrease in relative colony formation to 7.97 ± 9.20% as compared with control groups. |

实验结果 |
In A549 cells, the siRNA-V treatment showed a significant (P < 0.05) decrease of 62.58 ± 16.60% in VEGF gene expression compared to control (Figure 3a). siRNAV and PF0 combination treatment showed a significantly (P < 0.01) decreased VEGF expression of 75.06 ± 13.21% compared to control. In H460 cells, we observed a significant (P < 0.001) decrease in the relative VEGF mRNA expression after siRNA-V transfection by 92.22 ± 3.10% as well as after the combination treatment 69.59 ± 7.71% compared to control cells (Figure 3b). |

实验结果 |
We observed a significant (P < 0.05) decrease in relative cell viability for the combination compared to singleagent treatments (Figure 2a,b). The combination cytotoxicity assays demonstrated that siRNA-V potentiates the anticancer activity of PF0 against A459 and H460 cells. |

In H460 cells, PF0 (5 nmol/l to 200 µmol/l) or siRNA-V (5 to 200 nmol/l) cytotoxicity was also found to be dose and time dependent (Figure 1d,e and Supplementary Figure S2). IC50 values for PF0 in H460 cells were 1,965.5 ± 131.7 nmol/l; 1,080.1 ± 307.1 nmol/l; 936.7 ± 174.6 nmol/l after 24, 48, and 72 hours of treatment respectively (Figure 1d and Supplementary Figure S2a). |

方法 |
Cell proliferation assays. BT20, U87MG, and SKOV3 cells were plated at 3,000 cell/well in 96-well culture plates in growth medium with 10% FBS. Cells were incubated overnight and treated with DMSO (0.1% final) or serial diluted compound for 3 days. Resazurin was added to 0.1 mg/mL. Plates were incubated at 37°C in 5% CO2 for 3 hours. Fluorescence signals were read as emission at 590 nm after excitation at 530 nm. IC50 values were calculated by plotting fluorescence intensity to drug concentration in nonlinear curves. |
