The indication that vitamin D and its derivatives have a protective effect against various types of cancer is not new. In the field of colon cancer, numerous experimental and epidemiological studies show that vitamin D3 (or cholecalciferol) and some of its derivatives inhibit the growth of cancerous cells. Researchers at the Vall d'Hebron Institute of Oncology (VHIO), in collaboration with the Alberto Sols Institute of Biomedical Research (CSIC-UAB), have confirmed the pivotal role of vitamin D, specifically its receptor (VDR), in slowing down the action of a key protein in the carcinogenic transformation process of colon cancer cells. These results are being published in the journal PLoS One. http://medicalxpress.com/news/2011-08-vitamin-d-agent-advance-colon.html Cancer Tue, 16 Aug 2011 09:17:00 EST news232705003 A recently discovered enzyme drives the production of a potent form of estrogen in human breast cancer tissue, researchers from the University of Illinois at Chicago College of Medicine have found. http://medicalxpress.com/news/2011-05-enzyme-breast-cancer-growth.html Cancer Wed, 18 May 2011 16:14:24 EST news224954046 A breakthrough in understanding a biological process that causes many common cancers including lung and breast cancer opens up a whole new realm of possibilities for the development of improved cancer drugs.
