Cells Changing Identity May Trigger Deadly Liver Cancer
Jul 18, 2012
A rare type of cancer thought to derive from cells in the bile ducts of the liver may actually develop when one type of liver cell morphs into a totally different type, a process scientists used to consider all but impossible. UCSF researchers triggered this kind of cellular transformation - and caused tumors to form in mice - by activating just two genes... Read More
In Swedish Study, Mammography Screening Shows Limited Effect On Breast Cancer Mortality
Jul 18, 2012

Uncommon BRAF Mutation In Melanoma Sensitive To MEK Inhibitor Drug Therapy
Jul 18, 2012
An uncommon mutation of the BRAF gene in melanoma patients has been found to respond to MEK inhibitor drugs, providing a rationale for routine screening and therapy in melanoma patients who harbor the BRAF L597 mutation. The new study by co-first-authors Kimberly Brown Dahlman, Ph.D., Junfeng Xia, Ph.D., and Katherine Hutchinson, B.S., Vanderbilt-Ingram Cancer Center (VICC), Nashville, Tenn... Read More

Most Adults And Teens Not Exercising And At High Risk Of Disease
Jul 17, 2012
Not complying with physical activity recommendations is leaving around a third of adults (approx.1.5 billion people) and 4 out of 5 adolescents at a 20-30% greater risk of diabetes, heart disease, and some types of cancer, Brazilian researchers have found. The first paper in The Lancet Series on physical activity has calculated the first global estimate of physical activity levels... Read More
Dendritic Cells Key To Activating Human Immune Responses
Jul 17, 2012
Scientists at A*STAR's Singapore Immunology Network (SIgN), in collaboration with Newcastle University, UK, the Singapore Institute of Clinical Sciences and clinicians from multiple hospitals in Singapore, have identified a new subset of dendritic cells (DCs) in human peripheral tissue which have a critical role in activating our immune response against harmful pathogens...
