Abstract

The aim of the present study is to investigate the effect of a recombinant plasmid adenovirus (pAd) expressing human interferon-λ1 (hIFN-λ1) on the proliferation of the gastric adenocarcinoma cell line SGC‑7901. For this purpose, human gastric adenocarcinoma SGC-7901 cells were infected with recombinant pAd-hIFN-λ1, pAd-LacZ and phosphate‑buffered saline (PBS), respectively, and the subsequent effects on the proliferation of the infected cells were compared. Cell proliferation was evaluated by MTT assay, while mRNA and protein expression of hIFN‑λ1 were detected by reverse transcription‑polymerase chain reaction analysis and immunofluorescence assay, respectively. In addition, terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling assay and flow cytometry were conducted to analyze the rate of cell apoptosis. The results indicated that the proliferation of gastric adenocarcinoma SGC‑7901 cells was significantly inhibited by pAd‑hIFN‑λ1. Furthermore, the apoptosis rate and the mRNA and protein expression levels of hIFN‑λ1 were higher in pAd‑hIFN‑λ1‑transfected cells, compared with the pAd‑LacZ and PBS control groups. In conclusion, recombinant pAd‑hIFN‑λ1 induced the expression of hIFN‑λ1 in gastric adenocarcinoma SGC-7901 cells, and significantly inhibited cell proliferation by promoting apoptosis in these cancer cells.
