ABSTRACT
Objective To reveal the effects of circadian gene Per2 on growth of human lung cancer cell A549 cell and its mechanism. Methods pcDNA3.1(+)-Per2 was transfected into A549 cells and controlled with the vector pcDNA3.1(+). The expression of Per2 was confirmed with RT-PCR and western blot. The Inhibitory effect of Per2 on cell growth and proliferation was demonstrated with MTT assay and colony-forming assay. Apoptosis was detected with flow cytometry. Results The circadian gene Per2 exhibited a growth-inhibitory and apoptosis-inductory effect on A549 cells. Conclusion The results indicate that Per2 may inhibit A549 cell proliferation,which mechanism might involve cellular apoptosis.
