ZEB1 and cancer: Thus, the (1, 0) state obtained from the general minimal dynamic model means the high miR-200 and low ZEB expression level which corresponds to the epithelial phenotype (E) of cancer cell, the (0, 1) state means the low miR-200 and high ZEB expression level which corresponds the mesenchymal phenotype (M) of cancer cell, and the (1/2, 1/2) state means the intermediate expression level of both miR-200 and ZEB which corresponds to the epithelial/mesenchymal hybrid phenotype of cancer cell.
