LINC00607 and non-small cell lung carcinoma: In this study, we innovatively illustrated that LINC00607 was markedly downregulated in NSCLC, and LINC00607 suppressed NSCLC cell growth, migration, and invasion via modulating the miR-1289/EFNA5 axis, which indicated that LINC00607 functioned as a tumor suppressor in NSCLC.
