Objective: To investigate the effect of sevoflurane on the progression of cervical cancer cells, and to explore its effect on the cisplatinum (DDP) sensitivity in cervical cancer cells and underlying mechanism.
Methods: Siha and Hela cervical cancer cells were cultured and treated with 3% sevoflurane, 10 μmol/L DDP, or the co-treatment of sevoflurane and DDP, respectively. Cell proliferation was evaluated by the CCK8 assay. Cell apoptosis was assessed by flow cytometry. Cell migration was detected by wound healing assay. The expression of B-cell lymphoma-2 (BCL-2), B-cell lymphoma-2 associated X (BAX), Ezrin, matrix metalloproteinase 2 (MMP2), lung resistance-related protein (LRP), multiple drug resistance protein 1 (MRP1), glutathione-S-transferase-π (GST-π), and P glycoprotein (P-gp) protein was determined by Western blotting.
Results: After treated with sevoflurane, cell proliferation and migration rate in Siha and Hela cells were significantly elevated, while cell apoptosis was decreased. In addition, the expression of migration-related protein Ezrin and MMP2 was increased accordingly, apoptotic-related protein BCL-2 expression was also increased while BAX protein expression was decreased after sevoflurane treatment. The proliferation, migration rate, and apoptosis of Siha and Hela cells in sevoflurane plus DDP group were not significantly different with those in DDP group. There was no significant difference in apoptotic-related protein, migration-related protein, and drug resistance-associated proteins expression between DDP treatment group and combined treatment group.
Conclusion: Sevoflurane promotes the progression but has no effect on the cisplatinum sensitivity in cervical cancer cells.
