Differential formation of beta-catenin/lymphoid enhancer factor-1 DNA binding complex induced by nitric oxide in mouse colonic epithelial cells differing in adenomatous polyposis coli (Apc) genotype.

Abstract excerpt

Increased cytoplasmic beta-catenin levels and the associated nuclear beta-catenin/T-cell factor (Tcf)-lymphoid enhancer factor (LEF) complex formation have been frequently found in colon cancer. In this context, overproduction of nitric oxide (NO) attributable to inflammatory stimuli in diseases such as ulcerative colitis and Crohn's disease may-contribute to colonic carcinogenesis. Therefore, we examined the...
