MALAT1 and cancer: Long non‐coding RNAs (lncRNAs), a group of non‐protein coding transcripts longer than 200 nucleotides, play a key role in many types of malignant tumours, including glioma.8 LncRNAs may function as competing endogenous RNAs (ceRNAs) to modulate miRNA expressions.9 Metastasis‐associated lung adenocarcinoma transcript 1 (MALAT1) is an lncRNA with a length of approximately 8000‐nt.8 Wang et al revealed that MALAT1 was aberrantly expressed in carcinoma cells.10 Ma et al11 found that MALAT1 was up‐regulated in glioma tissues and correlated with the progression of glioma.
