LIN28A and cancer: Lin28, as an RNA‐binding protein and a reprogramming factor, can promote the tumourigenesis and progression in many human cancers.118 Evidence indicated that Lin28 also could participate in CSC regulation.119 Recently, Gong et al demonstrated that Linc00662 not only induced cell migration and invasive ability but also elevated the CSC percentage in NSCLC cells by the interaction with its downstream factor Lin28.120
