In a published January 5, 2011 in Science Translational Medicine, Anna Mandinova and Sam Lee, both researchers at Massachusetts General Hospital and associate members of the Ó³»´«Ã½, describe the obstacles and promise of developing small compounds that target the p53 pathway, the most common pathway involved in cancer. I asked them both to discuss the challenges of finding p53-targeted molecules and the approaches they are currently working on.
