Mechanism behind demethylation pinpointed in APC gene mutants

Colon cancer is the second most common cancer in the United States and causes more than 50,000 deaths each year. It has been known for some time that mutations in the APC gene occur in more than 85 percent of all sporadic colon cancers. Now researchers at Huntsman Cancer Institute at the University of Utah demonstrate in a study featured today in Cell the mechanism by which mutation of the APC gene affects a cellular process known as DNA methylation. DNA methylation is a chemical modification made to DNA that plays an important role in dictating how DNA is read and interpreted by a cell...
