Abstract：Long non-coding RNAs (lncRNAs) are now considered as central regulators in normal biological activites and critically involved in the tumorigenesis. The maternally expressed gene 3 (MEG3) is located in DLK1-DIO3 imprinted region on human chromosome 14q32.2. MEG3 gene is composed of 34.9 kb size and encodes an approximately 1.6 kb lncRNA. The MEG3 is either lost or down-regulated in a many primary human tumors and tumors derived cell lines, and exhibits the function of tumor suppressor. MEG3 controls the expression of some tumor suppressor genes and oncogenes, such as p53, RB, MYC and TGF-β. MEG3 also affects epithelial-mesenchymal transition through regulating the Wnt-β-catenin signaling pathway. In addition, the methylation modification and polymorphic sites within the MEG3 locus are also associated with cancer risk of and drug therapeutic response of patients. In this review, several aspects of MEG3 participating in tumorigenesis, and the potential value in cancer diagnosis and prognosis are discussed. This article provides a basis for the follow-up study of the role of MEG3 in human tumor therapy.
