Promoter‐wide analysis of Smad4 binding sites in human epithelial cells
24 Jul 2009
Abstract excerpt
Smad4, the common partner Smad, is a key molecule in transforming growth factor-beta (TGF-beta) family signaling. Loss of Smad4 expression is found in several types of cancer, including pancreatic cancer and colon cancer, and is related to carcinogenesis. Here we identified Smad4 binding sites in the promoter regions of over 25 500 known genes by chromatin immunoprecipitation on a microarray (ChIP-chip) in HaCaT...
