Objective To observe the effects of APOBEC3G on biological behaviors, including cell growth and migration ability, cell cycle and apoptosis of HepG2. 2. 15 cells after highly expressing APOBEC3G. Methods Eukaryotic expression vector pcDNA3. 1-APOBEC3G was transfected into HepG2.2.15 cells. HepG2.2.15 cells highly expressing APOBEC3G protein were screened by using limiting dilution method, and identified by using Western blotting. The changes of cell cycle and apoptosis were detected by using flow cytometry (FCM). The proliferation of cells was analyzed by MTT assay. The migration and movement of cells was determined by rowing trace. Results There were no significant changes in cell cycle among HepG2.2. 15-APOBEC3G cells (transfected with pcDNA3. 1-APOBEC3G),HepG2.2.15-pcDNA3.1 cells (transfected with blank vector) and HepG2.2.15 cells (control)[the proportions of each phase of cells were as follows: for G0/G1: (64.27 ± 1.26)% vs (64.18 ± 1.24)% vs (64.09 ±1.30)%,P>0.05; for S: (23.16 ±1.38)% vs (22.67 ±1.41)% vs (23.27 ±1.43)%,P>0.05; for G2/M: (11.36±1.26)% vs (11.84±1.31)% vs (11.37 ±1.22)%,P>0.05, respectively], apoptosis (P > 0.05), cell growth (P > 0.05 ), and the ability of cell migration[the inhibition rate of cell migration at 24 and 48 h was (7.5 ±3.7)% vs (10.2 ±5.5)% ,P>0.05; (13.4 ±6.5)%vs ( 17.8 ± 9.2 ) %, P > 0.05, respectively]. Conclusion Highly-expressed APOBEC3G has no obvious effects on biological behaviors of HepG2.2.15 cells.
