Protein expression of Bmi1, Sox2, p63 was reduced after ZEB1 knockdown.
ZEB1 knockdown not only resulted in reduced invasion and metastasis, but also in reduced tumorigenicity.
ZEB1 is also necessary for the self-renewing capacity.
ZEB1 is crucial for drug resistance in pancreatic cancer cells. This supports data showing that EMT activators (Twist and Snail) confer anti-apoptotic properties
