Abstract

Background: Glioma is a malignant brain tumor with poor prognosis. Sevoflurane has been shown to have antitumor effects in various cancers. However, the underlying role and mechanism of sevoflurane in glioma is still unclear. Materials and Methods: Glioma cell lines were exposed different concentrations of sevoflurane (sev). The cell proliferation and migration were examined by Cell Counting Kit-8 (CCK-8) and Transwell assays, respectively. All protein levels were measured by Western blot. The levels of noncoding RNA in the INK4 locus (ANRIL) and let-7b-5p were detected by quantitative real-time polymerase chain reaction. The binding sites between ANRIL and let-7b-5p were predicted by StarBase v.3.0 and confirmed using dual-luciferase reporter assay. Results: Sevoflurane treatment suppressed proliferation and migration of glioma cells. The expression of ANRIL was downregulated in glioma cells after treatment with sevoflurane in a dose-dependent manner, and overexpression of ANRIL reversed sevoflurane-induced inhibition of proliferation and migration of glioma cells. Furthermore, let-7b-5p was targeted by ANRIL, and ANRIL knockdown recovered the promoting effects of silencing let-7b-5p on proliferation, migration, and JAK2/STAT3 pathway in sevoflurane-treated glioma cells. Conclusions: Sevoflurane hindered proliferation and migration through JAK2/STAT3 pathway mediated by ANRIL and let-7b-5p in glioma cells, indicating a new reference for the application of anesthetics like sevoflurane in glioma.

七氟烷通过调节 ANRIL/let-7b-5p 轴抑制胶质瘤细胞的增殖和迁移
背景:胶质瘤是世界上预后较差的恶性脑肿瘤。七氟烷已被证明对多种癌症有抗肿瘤作用。然而,七氟烷在胶质瘤中的潜在作用和机制仍不清楚。材料和方法:使用不同浓度的七氟烷(sev)暴露于胶质瘤细胞系。细胞计数试剂盒-8(CCK-8)和 Transwell 试验分别检测了细胞的增殖和迁移。所有蛋白质水平均通过 Western 印迹法测定。实时定量聚合酶链反应检测了 INK4 基因座(ANRIL)中的非编码 RNA 和 let-7b-5p 的水平。用StarBase v.3.0预测了ANRIL和let-7b-5p的结合位点,并用双荧光素酶报告实验进行了确认。结果七氟烷处理抑制了胶质瘤细胞的增殖和迁移。七氟烷处理后,ANRIL在胶质瘤细胞中的表达呈剂量依赖性下调,而过表达ANRIL可逆转七氟烷诱导的胶质瘤细胞增殖和迁移抑制。此外,ANRIL靶向let-7b-5p,敲除ANRIL可恢复沉默let-7b-5p对七氟烷处理的胶质瘤细胞增殖、迁移和JAK2/STAT3通路的促进作用。结论七氟烷通过 ANRIL 和 let-7b-5p 介导的 JAK2/STAT3 通路阻碍了胶质瘤细胞的增殖和迁移,为七氟烷等麻醉剂在胶质瘤中的应用提供了新的参考。
