Sevoflurane is a commonly used anesthetic in cancer surgery. However, little information is available about the effects of sevoflurane on the osteosarcoma cells. The present study explored the effects of sevoflurane on the proliferation, migration and invasion of osteosarcoma cells, as well as the underlying mechanism. Human osteosarcoma cell lines U2OS and Saos-2 were pretreated with different concentrations (2.5%, 5%, or 10%) or different times (0, 2, 4 or 6 h) of sevoflurane. Cell viability, proliferation, migration, invasion and apoptosis were analyzed by MTT assay, Ki67 staining, colony formation assay, wound healing scratch assay, transwell assays and Annexin V-FITC/PI staining. Expression of key factors related to proliferation, migration, apoptosis, epithelial-mesenchymal transition (EMT) process and PI3K/AKT pathway were evaluated by western blotting. We found that sevoflurane significantly inhibited U2OS and Saos-2 cell viability, proliferation, migration and invasion, but induced cell apoptosis. Moreover, sevoflurane obviously inactivated PI3K/AKT pathway in U2OS and Saos-2 cells. Activator of PI3K/AKT pathway, insulin-like growth factor-1 (IGF-1) notably weakened the effects of sevoflurane on U2OS and Saos-2 cell proliferation, migration and apoptosis. Besides, sevoflurane suppressed EMT process in U2OS and Saos-2 cells. To sum up, our results evidenced that sevoflurane exerted anti-proliferative and anti-metastatic effects on osteosarcoma cells by inactivating PI3K/AKT pathway.

A long-acting calcium-blocking agent with significant anti-anginal activity. The drug produces significant coronary vasodilation and modest peripheral effects. It has antihypertensive and selective anti-arrhythmia activities and acts as a calmodulin antagonist.
Anti-inflammatory agents that are not steroids. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They are used primarily in the treatment of chronic arthritic conditions and certain soft tissue disorders associated with pain and inflammation. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. Certain NSAIDs also may inhibit lipoxygenase enzymes or TYPE C PHOSPHOLIPASES or may modulate T-cell function. (AMA Drug Evaluations Annual, 1994, p 1814-5)
