Abstract
Expression of the tight junction protein claudin-1 is dysregulated in colon tumors and associates with their progression. Up-regulation of claudin-1 reduces expression of E-cadherin. We investigated the mechanisms by which claudin-1 regulates E-cadherin expression and its effects in colon cancer cells.
