Evaluation of anti-tumor effect of iVR1-NP-Apa/Sal in vitro. (A) Cell growth rate of the MKN45/MDR cells after various treatments determined by evaluation of the absorbance values using the CCK-8 method. (B) Quantitative analysis of the cell apoptosis rate after treated with different nanoparticle formulations by the Annexin v-FITC/PI double staining method. (C) Qualitative evaluation of the cell apoptosis rate after various treatments through the Annexin v-FITC/PI double staining approach. (D) Cell migration rate and invasion rate were, respectively, investigated by the wound healing assay (the figures above) and trans-well experiment (the figures below). Quantitative analysis the migration rate (E) and invasion rate (F) of MKN-45/MDR cells after treated by different strategies. *p < 0.05 signally different from the group of Free Apa. #p < 0.05 signally different from the group of NPs-Apa/Sal.
