Mounting evidences discovered the role of lncRNAs in various diseases, for instance, DGCR5 was first reported to be decreased in Huntington’s disease20; DGCR5 inhibited cell proliferation, migration via bounding to miR‐320a in pancreatic cancer.18 The finding in pancreatic cancer suggested DGCR5 as the tumor suppressor. The gene discussed is DGCR5; the disease is familial pancreatic carcinoma.
