ZNFX1 antisense RNA 1 (ZFAS1), a LncRNA, originally identified a regulator of mammary development.19 Tian et al discovered that ZFAS1 was up‐regulated in NSCLC tissues and higher expression in more advanced tumour tissues.20 It was demonstrated that ZFAS1 exerted as ceRNA to enhance the expression of proliferation, invasion and metastasis‐related genes, such as ZEB1, MMP‐14, MMP16, BMI1, Sp1 and ZEB2 by competitively sponging miR‐150, miR‐200b or miR‐200c.21, 22. The gene discussed is ZEB1; the disease is non-small cell lung carcinoma.
