ABSTRACT
Objective To transfect a recombinant pcDNA3.1-DCN into HepG2 cells and detect the expressions of decorin(DCN) and p21WAF1/CIP1 so as to investigate the mechanism of tumor suppression of DCN.Methods HepG2 cells were divided into pcDNA3.1-dec-HepG2 group(transfected group) and pcDNA3.1-HepG2 group(control group).After the recombinant pcDNA3.1-DCN and pcDNA3.1 were transfected into HepG2 hepatoma cells by liposome,the stably transfected cell lines were established using G418 screening.RT-PCR method was used to detect the expressions of DCN and p21WAF1/ CIP1 mRNA;Western blotting method was used to detect the expressions of DCN and p21WAF1/CIP1 protein;immunohistochemistry was performed to detect the expression of DCN protein.Results Compared with control group,the expressions of DCN and p21WAF1/CIP1 mRNA were significantly increased in transfected group by RT-PCR(P
