摘要
Abstract
Objective To prepare a targeted ultrasound micro bubble,which carried the HSV-TK gene,and investigate the in vitro target searching ability of the micro bubbles and inhibitory effect on the proliferation of HepG2 cells.Methods Ultrasonic micro bubbles were prepared by mechanical vibration method,construction of targeted HSV-TK ultrasound micro bubbles by biotin affinity bridge construction.To detect the general characteristics of ultrasound micro bubbles,and to test its effect on the proliferation of HepG2 cells in vitro.Results HSV-TK targeted ultrasound microbubbles more gathered on the surface of HepG2 cells,through detection of PCNA and MTT,it was found that the proliferation of gene targeting microbubble group was obviously decreased,cell apoptosis increased significantly,Cells invade experiments showed that the number of cells in genetic microbubble group (22.18 ± 2.01) decreased significantly compared with the control group and the nontargeted group,can effectively inhibit the proliferation and invasive ability of HepG2 cells.Conclusion Targeted ultrasound microbubble carrying target gene have better inhibitory effect on HepG2 cells in vitro.关键词
