ZEB1 and cancer: These studies highlight the fact that firstly, Wnt can promote metastasis of cancer cells via ZEB1 up-regulation; secondly, the Wnt/ZEB1 axis can be inhibited by onco-suppressor miRs; thirdly, miRs affect both expression of Wnt and nuclear translocation of β-catenin; and finally, lncRNAs can regulate miR/Wnt/ZEB1 axis.
