Abstract:
Objective To investigate the effect of Smad3 on cell migration of A549 and HeLa cells.Methods Primers for pCMV-Myc-Smad3 plasmid construction and siRNA targeting Smad 3 were designed and synthesized .pCMV-Myc-Smad3 plasmid was constructed with molecular cloning techniques .Overexpression of Smad 3 with Myc-tag or silencing of endogenous Smad3, and then scratch assay was used to detect the migration ability of A 549 and HeLa cells in vitro. Results pCMV-Myc-Smad3 plasmid was successfully constructed .Overexpression of Smad 3 significantly up-regulated the migration rate of A549 and HeLa cells.Conversely, in the same cells, silencing of endogenous Smad3 or treatment with Smad3 inhibitor, SIS3, down-regulated the migration rate .Conclusions Smad3 promotes cell migration of A549 and HeLa cells.
