MEG3 and leukemia: To test if any prior evidence on the potential role of lncRNAs in leukemia progression existed, we queried the Oncomine Database (www.oncomine.org) for five lncRNAs: HOTAIR, ANRIL, MEG3, H19, and UCA1. All five lncRNAs were among the most cited lncRNAs associated with a potential role in cancer.
