Sevoflurane inhibits neuroblastoma cell proliferation and invasion and induces apoptosis by miR‐144‐3p/YAP1 axis

Sevoflurane (SEV) is a typical volatile anaesthetic and has an antitumour activity in various cancer cells. Here, we were curious whether SEV has tumour-suppressive effects in neuroblastoma (NB).NB cell lines (K-N-SH and SK-N-AS) were treated with SEV (1%, 2% and 4%). Cell Counting Kit-8 (CCK8) and Transwell assays were conducted to examine cell proliferation and invasion, respectively. The apoptosis was verified by flow cytometry, and the yes-associated protein 1 (YAP1), Bax, Bcl2 and cleaved caspase3 levels were detected by western blotting. Quantitative real-time PCR (qRT-PCR) was conducted to monitor the miR-144-3p level in SEV-treated NB cells. The targeted relationship between miR-144-3p and YAP1 was predicted by bioinformatics and testified by the dual-luciferase reporter assay.SEV mitigated NB cell proliferation and invasion and strengthened apoptosis dose-dependently. SEV upregulated miR-144-3p. Moreover, the miR-144-3p inhibitor transfection significantly reduced the tumour-suppressive effect of SEV on NB cells. Furthermore, the dual-luciferase reporter assay confirmed that miR-144-3p targeted YAP1 and overexpressing YAP1 partially weakened the inhibitive effects of miR-144-3p on NB cells.SEV abated NB cell proliferation and invasion and accelerated apoptosis through the miR-144-3p/YAP1 axis.
