CDH1 and colon carcinoma: HA/A and HA/B inhibit E-cadherin-mediated cell contacts (12, 13, 19) and promote the proliferation of Caco-2 cells (human colon carcinoma–derived epithelial cell line), T84 cells (human colon carcinoma–derived epithelial cell line), and Madin–Darby canine kidney type I (MDCK-I) cells (canine kidney epithelial cell line) (19).
