Both LIN28B and LIN28A from the LIN28 protein family function as RNA binding proteins in cells.14 Highly expressed LIN28 was first revealed in liver cancer tissues.15 Besides liver cancer, in neuroblastoma, lung cancer, pancreatic cancer, or colorectal cancer, LIN28B has also been found to be elevated.16, 17, 18, 19 In the present investigation, we revealed that LIN28B served as one target gene of miR‐563 in lung cancer. The gene discussed is LIN28A; the disease is lung carcinoma.
