Molecular Mechanism of Gas Anesthetics on the Invasion, Metastasis, and Chemosensitivity of Osteosarcoma Cells

Background Osteosarcoma is one of the most prominent bone cancers which has a predominant occurrence in children and adolescents. This study is focused on determining the effects of treatment of gas anesthetics on invasion, metastasis, and chemosensitivity in the progression of osteosarcoma cells. Material and Methods . The biological effects of the common gas anesthetics—desflurane, isoflurane, and sevoflurane—on osteosarcoma cells were studied and compared. The biological assays were performed for analysis of cell migration and proliferation.Results Isoflurane and sevoflurane have shown significant inhibition in the osteosarcoma cells at clinically relevant concentrations. Desflurane has shown less potent action on cell migration and inhibition. All three gas anesthetics have shown inhibition in cell proliferation. The effective antiproliferative action was at a clinically significant dose. At low millimolar concentrations, cell apoptosis was moderately affected. Drug combination analysis with chemotherapeutic drugs showed relevant inhibition in cell migration. All three agents showed significant augmentation of chemotherapeutic drugs in suppression and inhibition of inducing apoptosis. The antimigration action is likely to affect the PI3K/AKT pathway and IGF-1.Conclusion The study demonstrates the proposed mechanisms of gas anesthetics and their differential effects on osteosarcoma cells and their survival, migration, growth, and chemosensitivity.
