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. The results are featured on the front cover of the journal Molecular and Cellular Biology published today. http://medicalxpress.com/news/2011-05-octopus-cancer-breakthrough.html Cancer Fri, 13 May 2011 06:25:38 EST news224486698 A uniquely collaborative study by researchers at the Salk Institute for Biological Studies uncovered a novel mechanism that turns up glucose production in the liver when blood sugar levels drop, pointing towards a new class of drugs for the treatment of metabolic disease. http://medicalxpress.com/news/2011-05-fasting-pathway-class-diabetes-drugs.html Medical research Thu, 12 May 2011 12:25:32 EST news224421912 (Medical Xpress) -- Some of the most effective and expensive cancer drugs, dubbed "smart drugs" for their ability to stop tumors by targeting key drivers of cancer cell growth, are not effective in some patients. In two related studies, Yale School of Medicine researchers examined one such driver, the EGF receptor (EGFR), and found that a decoy receptor might be limiting the amount of drug that gets to the intended target. http://medicalxpress.com/news/2011-05-cancer-smart-drugs.html Cancer Wed, 11 May 2011 05:39:02 EST news224311055 (PhysOrg.com) -- Localized hyperthermia has been used occasionally with cancer drugs for some time, but until now, the reason it helps has been a mystery. In a report in the Proceedings of the National Academy of Sciences, scientists have discovered that the addition of heat inhibits homologous recombination so the cancer cells are unable to repair DNA damage caused by the cancer treatments. http://medicalxpress.com/news/2011-05-cancer-drugs.html Cancer Tue, 10 May 2011 15:00:01 EST news224255592
