Abstract:
OBJECTIVETo construct the recombinant plasmid pcDNA3.0-RGC32 and evaluate the effect of the response gene to complement-32 (RGC32) on cell cytoskeleton in vitro.
METHODSThe full-length cDNA of RGC32 was obtained by RT-PCR and inserted into the eukaryotic expression vector pcDNA3.0 to generate the recombinant plasmid pcDNA3.0-RGC32. After transfection of the recombinant plasmid into SW480 cells, the expression of RGC32 in the cells was detected by Western blotting. The cytoskeleton of SW480 cells was visualized before and after the transfection, and the changes in the cell migration ability was assessed by wound-healing assay.
RESULTSThe recombinant plasmid pcDNA3.0-RGC32 was successfully constructed. The expression of RGC32 was significantly increased in SW480 cells after transfection with pcDNA3.0-RGC32. Before the transfection, the microfilaments of SW480 cells were few and short without obvious polarity, but after the transfection, the microfilaments were increased and elongated with also an obvious polarity, and the invasive structures of lamellae and lamellipodia occurred. The migration ability of the cells was enhanced after transfection with pcDNA3.0-RGC32.
CONCLUSIONOverexpression of RGC32 can cause the reorganization of cytoskeleton and promotes the cell migration, which can be an important mechanism of RGC32 in promoting cancer metastasis.
