WITHDRAWN: Knockdown of LncRNA HOXA11 Antisense Promotes Glioma Cell Apoptosis Via Sponging MiR-140-5p

Long non-coding RNAs (lncRNAs) are proved as important regulators in many diseases, including multiple cancers. HOXA11antisense RNA (HOXA11-AS) is a novel identified lncRNA associated with cancer progression. However, the role of HOXA11-AS in glioma remains poorly understood and needs to be elucidated. The purpose of this study is to investigate the role and regulating mechanism of HOXA11-AS on gliomagenesis. Expression of HOXA11-AS was significantly up-regulated in glioma tissue and cell lines compared to the adjacent normal tissue and cells. Moreover, patients with high HOXA11-AS expression had a shorter survival time and poorer prognosis than that of lower expression. Loss-of-function experiments revealed that HOXA11-AS knockdown inhibited the proliferation, induced cell cycle arrest at G0/G1 phase and enhanced the apoptosis. Bioinformatics prediction forecast that miR-140-5p directly targeted HOXA11-AS at 3'-UTR, which was confirmed by luciferase reporter assay. In vitro rescue experiment assays, miR-140-5p inhibitor transfection could reverse the function of HOXA11-AS knockdown on the proliferation, cell cycle arrest and apoptosis. Together, present study illustrates that the pathway of HOXA11-AS sponging miR-140-5p might play a vital regulating role in the development and progression of glioma.
