Overexpression of lncRNA Pvt1 Oncogene (PVT1) promoted proliferation of non‐small cell lung cancer (NSCLC) cells by interaction with Enhancer of zeste homolog 2 (EZH2), thereby inhibiting the expression of large tumour suppressor kinase 2 (LATS2).4 The overexpression of FEZF1‐AS1 was found in colorectal cancer (CRC), which is a newly discovered carcinogenic lncRNA in human digestive tract cancer.5 This evidence concerns the gene PVT1 and lung cancer.
