Researchers in Stockholm, Sweden say they've isolated a gene that can help to prevent bowel cancer in mice. Scientists at The Karolinska Institute say when they remove the gene, the mice have a reduction of bowel cancer. The scientists say the specific gene's only known function is to regulate other genes. They describe it as a genetic relay switch. Doctors at the institute along with colleagues at the University of Helsinki say the gene region "MYC335" can turn on or off "MYC" which is a powerful cancer-associated gene. The leader of the research team says the findings could lead to preventative measures, but research remains at a basic level. Experts say risk factors for bowel cancer include being age 50 or older, drinking
alcohol, smoking, and obesity.
