Blood clots, often in the legs, are a frequent occurrence in patients fighting glioblastoma, the most common and the most aggressive form of brain cancer. Zerrouqi and http://www.gooakley.com/ Van Meir show that a tumor suppressor gene (p14ARF) that is often mutated in glioblastoma stops them from activating blood clotting.
