Gene expression analysis of HCT116 colorectal cancer cells with shRNA mediated control (GFP) or ZEB1 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 Cell). It is now known that EMT activation is also associated with the maintenance of stem-cell properties (Mani et al. 2008 Cell). 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 shRNA mediated loss of ZEB1 in HCT116 colorectal cancer cells. HCT116 is a cell line that exhibits mesenchymal characteristics, but reverts to an epithelial phenotype upon ZEB1 knock down (Spaderna et al. 2008 Cancer Research). HCT116 cells were stably transfected with control (GFP) or ZEB1 shRNA. Upon puromycin selection, single cell clones were picked and characterized. Cells from two control versus two ZEB1 knockdown clones were harvested, total RNA was isolated and processed to hybridization.
