ZFAS1 and cancer: 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 [41, 49], which indicated ZFAS1 became a new lncRNA functioning as ceRNA in cancer.
