Focally amplified lncRNA on chromosome 1 (FAL1), a new identified LncRNA located at 1q21.2, had been demonstrated to be up‐regulated and to promote development in several kinds of tumours, especially ovarian cancer.86 Pan et al reported that FAL1 was obviously overexpressed in NSCLC tissues compared with the adjacent normal tissues and promoted metastasis of NSCLC via the PTEN/AKT axis.87 Here, PTEN is linked to non-small cell lung carcinoma.
