The incidence rate of gliomas is the highest among primary brain tumors. Although the understanding of the molecular pathology of glioma has improved during the previous two decades, effective therapies are not yet available to treat these tumors. Previous studies have indicated that long non-coding RNAs (lncRNAs) have a close association with glioma, suggesting that lncRNAs may be potential targets for the development of novel treatments for glioma. The present review summarized the latest studies on the dysregulation of lncRNAs in glioma, and discussed their potential use in the diagnosis, prognosis and therapies of glioma...

Long non-coding RNA (lncRNA) dysregulation is involved in tumorigenesis and regulation of diverse cellular processes in gliomas. lncRNA SNHG12 is upregulated and promotes cell growth in human osteosarcoma cells. TAR-DNA binding protein 43 (TDP43) functions as an oncogene in various tumors by modulating RNA expression. Downregulation of TDP43 or SNHG12 significantly inhibited malignant biological behaviors of glioma cells. miR-195, downregulated in glioma tissues and cells, significantly impaired the malignant progression of glioma cells...

P73 antisense RNA 1T (non-protein coding), known as TP73-AS1 or PDAM, is a long noncoding RNA (lncRNA), which may regulate apoptosis by regulation of p53-dependent antiapoptotic genes. An abnormal change of TP73-AS1 expression was noticed in cancers. The effects of TP73-AS1 in brain glioma growth and the underlying mechanism remain unclear so far. In this study, the effect of TP73-AS1 in human brain glioma cell lines and clinical tumor samples was detected so as to reveal its role and function. In this study, TP73-AS1 was specifically upregulated in brain glioma cell lines and promoted glioma cell growth through targeting miR-124...

LncRNA HOX transcript antisense intergenic RNA (HOTAIR) has been shown to play prominent roles in tumorigenesis. However, its precise molecular mechanism in glioma has not been completely elucidated. In this study, we found that HOTAIR was aberrantly up-regulated in glioma tissues and was negatively correlated with miR-126-5p expression. Next, we determined that HOTAIR promote glioma progression by sponging miR-126-5p. Subsequently, glutaminase (GLS) was confirmed to be a direct target of miR-126-5p using bioinformatics software and a luciferase reporter assay...

Gliomas are one the most prevalent malignant carcinomas of the central nervous system, and angiogenesis plays a critical role in the progression of these blood vessel-rich tumors. HOTAIR, a long non-coding RNA (lncRNA), acts as an oncogene in gliomas; however, its role in glioma angiogenesis remains unclear. In the present study, we identified a pro-angiogenic activity of HOTAIR. Silencing HOTAIR inhibited glioma-induced endothelial cell proliferation, migration, and tube formation. Further studies showed that vascular endothelial growth factor A (VEGFA) was involved in the HOTAIR-induced glioma angiogenesis...

The colorectal neoplasia differentially expressed (CRNDE) gene encodes a long non-coding RNA (lncRNA) that is the most unregulated among 129 lncRNAs differentially expressed in gliomas. In this study, we confirmed high CRNDE expression in clinical glioma specimens and observed through experiments in human glioma cell lines a novel molecular mechanism by which CRNDE may contribute to glioma pathogenesis. By inducing or silencing CRNDE expression, we detected a positive correlation between CRNDE levels and the proliferative, migratory, and invasive capacities of glioma cells, which were concomitant with a decreased apoptosis rate...

Long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) play a significant role in cancer development as regulators of protein-coding genes. Their dysregulation was in some extent already associated with glioma, the most aggressive primary brain tumours in adults. The correct diagnosis and treatment selection due to high tumour heterogeneity might be difficult and inadequate, resulting in poor prognosis. Studies of expression patterns of noncoding RNAs (ncRNAs) could provide useful insight in glioma molecular development...
