DCN transfection inhibited the proliferation of HepG2 cells. (A) DCN was transfected into HepG2 cells with Lipofectamine 2000 (magnification, ×100). (B) Statistical analysis of the DCN mRNA expression levels in HepG2 cells, detected with quantitative polymerase chain reaction. (C) Cell proliferation of HepG2 cells was assessed by MTT assay. Data are expressed as the mean ± standard deviation. *P<0.05, vs. control group. DCN, decorin-transfected group; EGFP, enhanced green fluorescent protein.
