Objectives: Long non‐coding RNAs (lncRNAs) are a group of non‐protein‐coding RNAs that are greater than 200 nucleotides in length. Increasing evidence indicates that lncRNAs, which may serve as either oncogenes or tumour suppressor genes, play a vital role in the pathophysiology of human diseases, especially in tumourigenesis and progression. Deregulation of lncRNAs impacts different cellular processes, such as proliferation, dedifferentiation, migration, invasion and anti‐apoptosis. The aim of this review was to explore the molecular mechanism and clinical significance of long non‐coding RNA‐activated by transforming growth factor β (lncRNA‐ATB) in various types of cancers.Materials and methods: In this review, we summarize and analyze current studies concerning the biological functions and mechanisms of lncRNA‐ATB in tumour development. The related studies were obtained through a systematic search of Pubmed, Web of Science, Embase and Cochrane Library.Results: Long non‐coding RNAs‐ATB is a novel cancer‐related lncRNA that was recently found to exhibit aberrant expression in a variety of malignancies, including hepatocellular carcinoma, colorectal cancer, gastric cancer, and lung cancer. Dysregulation of lncRNA‐ATB has been shown to contribute to proliferation, migration and invasion of cancer cells. Long non‐coding RNAs‐ATB promotes tumourigenesis and progression mainly through competitively binding miRNAs to induce epithelial‐mesenchymal transition (EMT).Conclusions: Long non‐coding RNAs‐ATB likely represents a feasible cancer biomarker or therapeutic target.

Long non-coding RNAs (lncRNAs), which are a portion of non-protein-coding RNAs (ncRNAs), have manifested a paramount role in the pathophysiology of human diseases, particularly in pathogenesis and progression of disease. Myocardial infarction associated transcript (MIAT), which was recently found to demonstrate aberrant expression in various diseases, such as myocardial infarction, schizophrenia, ischemic stroke, diabetic complications, age-related cataract and cancers, is a novel disease-related lncRNA. This work summarize current evidence regarding the biological functions and underlying mechanisms of lncRNA MIAT during disease development. LncRNA MIAT likely represents a feasible cancer biomarker or therapeutic target.

Long non‐coding RNAs (lncRNAs) recently emerge as a novel class of non‐coding RNAs (ncRNAs) with larger than 200 nucleotides in length. Due to lack an obvious open reading frame, lncRNAs have no or limited protein‐coding potential. To date, accumulating evidence indicates the vital regulatory function of lncRNAs in pathological processes of human diseases, especially in carcinogenesis and development. Deregulation of lncRNAs not only alters cellular biological behavior, such as proliferation, migration and invasion, but also represents the poor clinical outcomes. Zinc finger E‐box binding homeobox 1 antisense 1 (ZEB1‐AS1), an outstanding cancer‐related lncRNA, is identified as an oncogenic regulator in diverse malignancies. Dysregulation of ZEB1‐AS1 has been demonstrated to exhibit a pivotal role in tumorigenesis and progression, suggesting its potential clinical value as a promising biomarker or therapeutic target for cancers. In this review, we make a summary on the current findings regarding the biological functions, underlying mechanisms and clinical significance of ZEB1‐AS1 in cancer progression.
