ZEB1 and cancer: The lncRNA ATB promotes the EMT of several types of cancer cells [4,124,126,127] via sponging miR-200s, an EMT suppressor inhibiting ZEB1/2 expression via direct binding to their 3′UTR, which is detected between ATB and miR-200a/b/c in an RNA immunoprecipitation (RIP) experiment [4,138,139].
