ABSTRACT
Objective:To investigate the effects of ultrasound microbubble-mediated RasGAP SH3-binding protein 1 (G3BP1) transfection on the proliferation and migration of human liver cancer HepG2 cells.Methods:HepG2 cells were treated with ultrasound targeted microbubble destruction (UTMD) technology-mediated si-G3BP1. The expression of G3BP1 in HepG2 cell lines was detected by Western blot, and the silencing efficiency was analyzed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western blot. HepG2 cell proliferation and migration were analyzed by flow cytometry, methyl thiazolyl tetrazolium (MTT) , EdU staining, colony formation experiment, wound healing experiment, Transwell experiment and Western blot.Results:After silencing G3BP1 in HepG2 cells, its mRNA and protein levels were significantly reduced (1.01±0.03 vs 0.27±0.03, 1.02±0.01 vs 0.33±0.04) ; UTMD-mediated si-G3BP1 could significantly reduce the proliferation rate (31.49±3.09 vs 12.51±1.02) , proliferation activity (1.20±0.13 vs 0.46±0.31) , EdU-positive cell rate (99.23±1.01 vs 36.75±4.03) , colony formation rate (96.45±1.21 vs 32.67±2.62) , scratch healing rate (97.58±1.04 vs 42.33±2.56) , migration rate (94.28±2.33 vs 39.36±2.51) and Ki67, Cyclin D1, Vimentin protein levels, increase E-cadherin protein levels.Conclusion:UTMD-mediated si-G3BP1 can inhibit the proliferation and migration of human liver cancer HepG2 cells.
