Abstract:

Objective  To construct the recombinant plasmids of knocking down Rho guanine dissociation inhibitor α (GDIα) gene by using clustered regularly interspaced short palindromic repeats/associated protein 9 (CRISPR/Cas9) technique, and investigate the effect of Rho GDIα interference on the migration of Hepa 1-6 cells of mouse in order to provide the method  of prevention and treatment of liver cancer.   Methods  To construct and identify the PX458-Rho GDIα-single guide(sg)RNAs by using CRISPR/Cas9 technique. And the Hepa 1-6 cells were transfected by liposomes with PX458-Rho GDIα-sgRNAs for 48 hours respectively, and cells treated with PX458 plasmids were used as control. The migration ability of Hepa 1-6 was checked by wound healing assay and Transwell assay, respectively.  Results  The expression of Rho GDIα was depressed in group of PX458-Rho GDIα-sgRNA1 transfection which was detected by using RT-PCR. The migration distance of Hepa 1-6 in PX458-Rho GDIα-sgRNA1 transfection group was significantly promoted comparing with the control group which was transfected with PX458 only, and the cell number of PX458-Rho GDIα-sgRNA1 group was more than that in control group by using transwell assay, indicating concluded that knocking down of Rho GDIα promoted the migration ability of Hepa1-6 cells.
  Conclusion  The result  is explicit that in vivo, Rho GDIα may inhibit the migration of Hepa1-6 partially. Overexpression of Rho GDIα  might be used as an important method  to prevent the metastasize of carcinoma.
