Abstract

AbstractBackgroundLong non-coding RNA MAGI2 antisense RNA 3 (MAGI2-AS3) has been identified as a tumor suppressor in various cancers. Acute lymphoblastic leukemia (ALL) is a prevalent kind of leukemia among children. In this study, we aimed at evaluate the role of MAGI2-AS3 in ALL and its underlying mechanisms.MethodsqPCR was adopted to determine MAGI2-AS3, miR-452-5p, and FOXN3 expression. The malignant properties of ALL cells were assessed by CCK8 assay and flow cytometry analysis. The glucose uptake, lactate production, and ATP level were measured to evaluate glycolysis. Western blotting was performed to detect PCNA, Bcl-2, Bax, and HK2 protein levels. The interaction between MAGI2-AS3/FOXN3 and miR-452-5p was validated by luciferase reporter assay. The in vivo growth of ALL cells was determined in xenograft model.ResultsMAGI2-AS3 was strikingly down-regulated in ALL samples and cells. Overexpression of MAGI2-AS3 restrained growth, glycolysis and triggered apoptosis of ALL cells. Mechanistically, MAGI2-AS3 could sponge miR-452-5p to up-regulate FOXN3. Silencing of FOXN3 abolished the anti-tumor effect of MAGI2-AS3. Finally, MAGI2-AS3 suppressed the in vivo growth of ALL cells via modulating miR-452-5p/FOXN3 axis.ConclusionOur findings demonstrate that MAGI2-AS3 delays the progression of ALL by regulating miR-452-5p/FOXN3 signaling pathway.
