Shortened gene region linked to breast cancer

Reza Zarnegar and colleagues, at the University of Pittsburgh, Pittsburgh, have determined that genetic variation in a piece of DNA that regulates activity of the HGF gene might be a useful marker to identify individuals with an increased risk of developing breast cancer.

New potential targets for colitis-associated cancer

Recent research from the laboratory of Michael Karin, PhD, at the University of California, San Diego School of Medicine - the first researcher to demonstrate a molecular link between inflammation and cancer - has identified two potential targets for the prevention and treatment of colitis-associated cancer (CAC), the most serious complication of inflammatory bowel disease.

Century old drug clofazimine shows potential for multiple sclerosis

A century-old drug that failed in its original intent to treat tuberculosis but has worked well as an antileprosy medicine now holds new promise as a potential therapy for multiple sclerosis and other autoimmune diseases.

New CDC study assesses impact of genetic testing on health outcomes

Some genomic tests developed to personalize medical decisions about cancer care are beneficial, while for others the evidence is uncertain and reliance on the test might even lead to poorer medical management of cancer in some cases, according new recommendation statements from an expert panel.
