Gene expression analysis of SW480 colorectal cancer cells with siRNA mediated ZEB1 or control (GFP) knockdown


ABSTRACT: Epithelial-to-mesenchymal transition (EMT) is a fundamental process in development and disease. If aberrantly activated it is a trigger for tumour progression and metastasis (Thiery et al, 2009). It is now known that EMT activation is also associated with the maintenance of stem-cell properties (Mani et al, 2008). Since Zinc-finger enhancer binding transcription factor 1 (ZEB1) is a crucial EMT activator, we analyzed the changes in the gene expression profile that accompany siRNA mediated loss of ZEB1 in SW480 colorectal cancer cells. SW480 is a cell line that exhibits mesenchymal characteristics, but reverts to an epithelial phenotype upon ZEB1 knock down (Spaderna et al. 2006 Gastroenterology). SW480 cells were transfected with control (GFP) or ZEB1 siRNA. 72 hours after transfection, cells were harvested, total RNA was isolated and hybridized.
