Core Tip
Core tip: Deregulated Wnt/β-catenin signaling is responsible for initiating most human colorectal cancer (CRC), and hyperactivation of this pathway by histone deacetylase inhibitors such as butyrate, derived from dietary fiber, promotes CRC cell death. The transcriptional cofactors CREB-binding protein (CBP) or p300 affect Wnt signaling and the hyperactivation of this pathway by butyrate. CBP and p300 likely affect colonic tumorigenesis, stem cell fate, and butyrate resistance in CRC. Therefore, pharmacological or genetic methodologies that target CBP- and p300-mediated Wnt activity are possible preventive or therapeutic approaches against CRC.
