B Y Yang, Q Meng, Y Sun, L Gao, J X Yang
Glioma is among the most fatal and highly aggressive primary malignant tumors in the central nervous system. Small nucleolar RNA host gene 16 (SNHG16) is identified to play an oncogenic role in several cancers. However, the exact mechanism of SNHG16 action in the regulation of glioma development remains unknown. LncRNA SNHG16 was increased in glioma tissues and cells compared with normal brain tissues and cells. SNHG16 expression was correlated with the malignancy and poor prognosis of glioma patients. SNHG16 and E2F1 contained a binding site of miR-20a-5p...

Glioblastoma (GB) is the most common and deadliest malignant primary brain tumor with a high recurrence. In this study, lncRNA UCA1/miR-182 axis has been regarded as a nodal driver of glioma invasion mediated by GB-associated stromal cells (GASCs) and GASC-secreted chemokine CXCL14. In clinical specimens, CXCL14 upregulation in GASCs also correlated with poor prognosis. Notably, CXCL14-high GASCs mediated lncRNA UCA1 upregulation and miR-182 downregulation in glioma cells. Moreover, miR-182 directly bound to the fructose-2,6-biphosphatase PFKFB2; UCA1/miR-182 axis thereby modulated GASC-induced glycolysis in glioma cells...

The lncRNA HOTAIR has been implicated in several human cancers. Here, we evaluated the molecular alterations and upstream regulatory mechanisms of HOTAIR in glioma, the most common primary brain tumors, and its clinical relevance. HOTAIR gene expression, methylation, copy-number and prognostic value were investigated in human gliomas integrating data from online datasets and our cohorts. High levels of HOTAIR were associated with higher grades of glioma, particularly IDH wild-type cases. Mechanistically, HOTAIR was overexpressed in a gene dosage-independent manner, while DNA methylation levels of particular CpGs in HOTAIR locus were associated with HOTAIR expression levels in GBM clinical specimens and cell lines...

Malignant glioma is an aggressive type of brain tumor with poor prognosis and mostly incurable. Although cisplatin is used for adjuvant chemotherapy against glioma, intrinsic and acquired resistance restricts the application of cisplatin. Long noncoding RNA (lncRNA) DANCR is reported to regulate the differentiation and progression of several cancers. However, whether DANCR participates in cisplatin resistance of glioma is still unknown. In this study, we found that DANCR expression was negatively correlated with cisplatin sensitivity in glioma cells...
