A new study led by Massachusetts General Hospital (MGH) investigators finds that radiation therapy may increase the uptake of therapeutic nanoparticles by glioblastomas, raising the possibility of using both growth-factor-targeted and immune-system-based therapies against the deadly brain tumor. The team describes how pretreatment with low-dose radiation increased delivery to tumors of nanoparticles carrying small interfering RNA (siRNA) molecules and significantly improved survival in a mouse model of glioblastoma.
