Abstract

Propofol has a tumor-suppressive role in glioma, but the mechanism by which propofol is involved in glioma progression is largely unknown. This study aims to explore a potential circular RNAs (circRNAs)/microRNAs (miRNAs)/mRNA network in response to Propofol in glioma. Human glioma cell lines (U251 and LN229) were suffered from Propofol treatment (5 μg/mL for 24 h) and transfection. circRNA mitogen-activated protein kinase 4 (circMAPK4), miR-622, homeobox A9 (HOXA9) abundances were determined by quantitative reverse transcription polymerase chain reaction and western blot. Migration and invasion were analyzed via transwell analysis. Cell proliferation was evaluated using Cell Counting Kit-8 and colony formation analysis. Cell apoptosis and related protein expression were determined via flow cytometry and western blot. Target relationship was assessed via dual-luciferase reporter analysis, RNA pull-down and RNA immunoprecipitation. Propofol reduced circMAPK4 expression. Propofol inhibited cell proliferation, migration and invasion, while increased apoptosis via decreasing circMAPK4 in glioma cells. miR-622 was targeted via circMAPK4. circMAPK4 knockdown decreased glioma cell growth, migration and invasion by up-regulating miR-622. miR-622 knockdown reversed the effect of Propofol on glioma progression. HOXA9 was targeted by miR-622, and its expression was decreased by Propofol treatment. miR-622 overexpression restrained glioma progression via decreasing HOXA9. Propofol regulated circMAPK4/miR-622/HOXA9 axis in glioma cells. Propofol constrains glioma progression by regulating circMAPK4/miR-622/HOXA9 axis in vitro. Propofol restrains glioma cell growth, migration and invasion. circMAPK4 can regulate HOXA9 by sponging miR-622 in glioma cells. Propofol represses glioma progression via a circMAPK4/miR-622/HOXA9 axis.
