Adenovirus-mediated wild-type P53 expression suppresses growth of lung adeno-carcinoma cells

Objective: To study the growth suppression of lung adenocarcinoma cell by the introduction of wild-type P53 gene and explore a gene therapy approach for lung adenocarcinoma. Methods: A replication-deficient adenovirus vector encoding a wild-type P53 was constructed and transfected into the cultured human lung adenocarcinoma cell line GLC-82. The efficiency of gene transfection and expression was detected by immunochemical staining and polymerase chain reaction. The cell growth rate and cell cycle were analysed by cell-counting and flow cytometry. Results: Wild-type P53 gene could be quickly and effectively transfected into the cells by adenovirus vector. Wild-type P53 expression could inhibit GLC-82 cell proliferation and induce apoptosis. Conclusion: The results indicated that recombinant adenovirus expressing wild-type P53 might be useful vector for gene therapy of human lung adenocarcinoma.
