Purpose:
Glioma is a malignant tumor in the central nervous system. Long non-coding RNA (lncRNA) RNF144A-AS1 exerts a regulatory effect in cancers, but its role in glioma remains obscure and needs to be further study.
Methods:
Expressions of RNF144A-AS1, miR-665 and High-mobility group A1 (HMGA1) in glioma tissues and/or cells were determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR). The relationship between miR-665 and RNF144A-AS1/HMGA1 was determined by bioinformatics and Dual-Luciferase Reporter assay. The effect of RNF144A-AS1 on the biological functions of glioma cells was confirmed by loss and gain experiments (including cell counting kit 8, clone formation, wound healing, Transwell, qRT-PCR and western blot). The regulatory mechanism of RNF144A-AS1/miR-665/HMGA1 axis on glioma was confirmed by rescue experiments.
Results:
RNF144A-AS1 and HMGA1 were high-expressed in gliomas, and miR-665 was low-expressed in gliomas, which led to the increase of glioma cell viability, proliferation, migration and invasion ability and insufficient apoptosis ability. Overexpression of RNF144A-AS1 suppressed the expressions of Bax and cleaved caspase-3, and promoted Bcl-2 expression. RNF144A-AS1 up-regulated the expression of HMGA1 by targeting miR-665, thereby promoting the development of glioma cells.
Conclusion:
RNF144A-AS1/miR-665/HMGA1 axis implicated in the development of glioma.
