A study from scientists at the University of Freiburg, Germany, and their collaborators at the National Cancer Institute (NCI), part of the National Institutes of Health, has pinpointed a potential mechanism for resistance of Ewing’s sarcoma, a type of bone cancer, to a protein that may be useful in fighting cancer — and a possible method for overcoming this resistance. The results appear online May 23, 2007, in the Journal of Pathology.
