Moreover, it has been reported that lncRNA colon cancer associated transcript 1 (CCAT1) is primarily associated with malignant transformation of lung cancer, whose mechanism is probably to indirectly promote the c‐Myc activity in human bronchial epithelial cells induced by cigarette smoke exposure to induce malignant transformation, thereby promoting lung cancer's occurrence and development (Tran et al., 2015). Here, MYC is linked to lung carcinoma.
