Silencing of lncRNA LBX2-AS1 suppresses glioma cell proliferation and metastasis through the Akt/GSK3β pathway in vitro

Acta Biochim Biophys Sin (Shanghai). 2021 Mar 26;53(4):446-453. doi: 10.1093/abbs/gmab011.

Abstract

Long non-coding RNAs (lncRNAs) have been proposed to play pivotal roles in the tumorigenesis of various malignant tumors. Previous studies have found that lncRNA LBX2-AS1 is involved in the progression of various tumors. However, currently, the expression and exact mechanism of LBX2-AS1 in glioma remain unclear. In this study, using online-available datasets combined with clinical glioma tissues collected, we found that LBX2-AS1 was significantly increased and negatively correlated with prognosis in glioma. In vitro functional assays such as CCK-8, Annexin V, transwell assay, and western blot analysis showed that silencing of LBX2-AS1 suppressed the proliferation, migration, and invasion of glioma cells and increased apoptosis. RNA sequencing and western blot analysis confirmed that LBX2-AS1 regulates the Akt/GSK3β pathway. In conclusion, this study showed that lncRNA LBX2-AS1 depletion inhibits the proliferation, migration, and invasion of glioma cells and increases apoptosis through the Akt/GSK3β pathway. lncRNA LBX2-AS1 is expected to become a new target for glioma therapy.

Keywords: LBX2-AS1; glioma; lncRNA; migration; proliferation.
