lncRNA maternally expressed gene 3 (MEG3) is localized on human chromosome 1432.3 and can be widely expressed in normal human tissues, with decreased expression in some tumor cells, and MEG3 overexpression can inhibit tumor cell proliferation and migration (Shihabudeen Haider Ali et al., 2019; Benetatos et al., 2011). This evidence concerns the gene MEG3 and neoplasm.
