ABSTRACT
Objective To assess the effects of p27mt gene transfection on the proliferation and apoptosis of human hepatocellular carcinoma cell (HCC) lines SMMC-7721. Methods A replication deficient adenovirus vector encoding p27mt (Ad-p27mt) was used and p27mt cDNA was transfected into human SMMC-7721 cell lines in vitro. The synthesis of DNA in SMMC-7721 cells was determined by using 3H-thymidine incorporation; the cell apoptosis was determined by flow cytometry, TUNEL method and DNA fragmentation analysis. Results The virus titer was 7.95?1012 cfu/ml, the transduction efficiency was 100 % when multiplicity of infection ≥50, FCM analysis revealed a sub-G1 cell peak in Ad-p27mt transduced hepatocellular carcinoma cell lines. Agarose electrophoresis showed marked ladder .The difference of apoptotic index between the Ad-p27mt group and the control group was statistically significant (58.6?4.3, vs 4.5?1.6, P
