Flow cytometry and confocal laser scanning microscopy demonstrated that the derivative could realize the cellular uptake of nanoparticles in an energy-dependent and clathrin-mediated pathway and obtain a high DNAzyme concentration in the cytoplasm through further endosomal escape. After DNAzyme transfection, expression level of aurora kinase A would be downregulated at the protein level. Meanwhile, the inhibition of cell proliferation was observed through 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and cell colony formation assay, attributing to the activation of apoptosis and cell cycle arrest. Through flow cytometric analysis, an early apoptotic ratio of 25.93% and G2 phase of 22.58% has been detected after N-Ac-L-Leu-PEI-mediated DNAzyme transfection. Finally, wound healing and Transwell migration assay showed that DNAzyme transfection could efficiently inhibit the cell migration. These results demonstrated that N-Ac-L-Leu-PEI could successfully mediate the DNAzyme delivery and downregulate the expression level of aurora kinase A, triggering a significant inhibitory effect of excessive proliferation and migration of tumor cells.
