ABSTRACT
PURPOSE:
Sevoflurane, an inhalational anesthetic, is used extensively during lung cancer surgery. However, the effect of sevoflurane on growth of lung carcinoma cells remains unclear. The purpose of this study is to investigate effects on proliferation, apoptosis, and cell cycling in the A549 human lung adenocarcinoma cell line.METHODS:
A549 cells were treated with 1.7%, 3.4%, and 5.1 % sevoflurane for 2, 4, and 6 hours. Cell proliferation was evaluated by the MTT assay and colony formation assay. Apoptosis and cell cycle was analyzed by flow cytometry. Expression of X-linked inhibitor of apoptosis protein (XIAP), survivin, Bcl-2, Bax, caspase-3, cyclin A, cyclin B1, and cdc2 was measured by Western blotting.RESULTS:
Significant inhibition of cell proliferation and induction of apoptosis were found in A549 cells after sevoflurane treatment. Simultaneously, expression of XIAP and survivin was supressed, while that of caspase-3 increased significantly, but Bcl-2 and Bax were not altered. Sevoflurane caused cell cycle arrest at the G2/M phase. At the same time, data revealed that cyclin A, cyclin B1, and cdc2 expression was down-regulated after sevoflurane treatment.CONCLUSION:
This study demonstrated that sevoflurane inhibited proliferation, and induced apoptosis in human lung adenocarcinoma A549 cells, associated with down-regulated expression of XIAP and suvivin, and activating caspase-3.
