Researchers at McGill University have identified a new cellular pathway that limits the growth and spread of brain tumors by controlling the recycling of cell surface receptor proteins. The study, which will be published January 14 in the Journal of Cell Biology (JCB), suggests that the pathway, which involves a protein called Rab35, is defective in many patients with glioblastoma and that restoring Rab35’s activity could be a new therapeutic strategy for this deadly form of brain cancer.
