With the rise of studies on the functional properties of lncRNAs, it has been verified that lncRNAs can efficiently affect the biological processes of cancers, some of which may serve as tumor or metastasis inhibitors, such as GAS5 [23] and MEG3 [24], while others may promote oncogenesis, such as SChLAP1 [25]. The gene discussed is MEG3; the disease is cancer.
