MALAT1 and lung cancer: Accumulating biological roles of lncRNAs have been reported in lung cancer progression.18, 19, 20 For example, MALAT1 serves as an important regulator of lung cancer.21 Knockdown of PVT1 can enhance NSCLC radiosensitivity by sponging miR‐195.22 In addition, XIST promotes NSCLC progression by modulating miR‐186‐5p.23 In recent years, a great deal of evidence has proved that LINC‐PINT can exert an important role in tumors.
