Dietary fiber intake is linked to a reduced risk of colon cancer. This effect may in part be due to butyrate, the fermentation product of fiber in the colon. Butyrate is a short-chain fatty acid that acts as a histone deacetylase inhibitor (HDACi). Butyrate induces apoptosis and represses clonal growth of colorectal cancer (CRC) cells, in a manner dependent(More)
Deregulated WNT/catenin pathway, usually resulting from mutations in the adenomatous polyposis coli and beta-catenin genes, drives colorectal tumorigenesis. Dietary fiber has been shown to have a protective role against colorectal cancer (CRC). We have previously demonstrated that the histone deacetylase inhibitor (HDACi) butyrate, a fermentation product of(More)
Mutations in the WNT/beta-catenin pathway are responsible for initiating the majority of colorectal cancers (CRCs). We have previously shown that hyperactivation of this signaling by histone deacetylase inhibitors (HDACis) such as butyrate, a fermentation product of dietary fiber, promotes CRC cell apoptosis. The extent of association between beta-catenin(More)
