To observe the effect of proliferating cell nuclear antigen (PCNA) antisense RNA on the growth characteristics of human gastric cancer cell. An eukaryotic expression vector pDR-PCNA with human PCNA gene insert in reverse direction was successfully constructed. The human gastric cancer cell line SGC-7901 was transfected with pDR-PCNA by lipofectamine. Growth rate, protein and RNA biosynthesis and DNA contents in S-phase and G2/M-phase of the transfected SGC-7901 were significantly suppressed in comparison with those of the parental cell line. PCNA antisense RNA can significantly suppress the in vitro growth of gastric cancer cell line.
