SMAD4 suppresses WNT-driven dedifferentiation and oncogenesis in the differentiated gut epithelium
The cell of origin of colon cancer is typically thought to be the resident somatic stem cells,
which are immortal and escape the continual cellular turnover characteristic of the intestinal …

Induction of Protein Tyrosine Kinase 6 in Mouse Intestinal Crypt Epithelial Cells Promotes DNA Damage–Induced Apoptosis
A Haegebarth, AO Perekatt, W Bie, JJ Gierut, AL Tyner - Gastroenterology, 2009 - Elsevier
