Chemopreventive Action of Mesalazine on Colorectal Cancer: a Pilot Study for an "in Vivo" Evaluation of the Molecular Effects on β-catenin Signaling Pathway.

Summary

The purpose of this study is to obtain an "in vivo" confirmation that mesalazine induces the gene expression of μ-protocadherin and other related genes in the colon mucosa, as demonstrated in some "in vitro" experiments. .
