(Medical Xpress)—A team of researchers at McGill University have discovered a molecular basis for the potential cancer preventive effects of vitamin D. The team, led by McGill professors John White and David Goltzman, of the Faculty of Medicine's Department of Physiology, discovered that the active form of vitamin D acts by several mechanisms to inhibit both the production and function of the protein cMYC. cMYC drives cell division and is active at elevated levels in more than half of all cancers. Their results are published in the latest edition of Proceedings of the National Academy of Sciences. http://medicalxpress.com/news/2012-11-vitamin-d-cells-premalignant-malignant.html Cancer Fri, 23 Nov 2012 07:19:01 EST news272877506 A blistering sunburn during childhood or adolescence more than doubles the adult risk of skin cancer. The accumulation of long-term sun exposure may be equally dangerous. A study from the Colorado School of Public Health and the University of Colorado Cancer Center recently published in the American Journal of Preventive Medicine shows one way to reduce this exposure: a double-blind randomized clinical trial of mailed sun protection packets led to higher frequency of sun protective behaviors including the use of long clothing, hats, shade, sunscreen, and midday sun avoidance. http://medicalxpress.com/news/2012-09-three-year-child-trial-effectiveness-low-cost.html Health Mon, 24 Sep 2012 11:34:11 EST news267705240
