Alonzo H. Ross, PhD (Damon Runyon Fellow ‘77-‘78) of the University of Massachusetts Medical School, Worcester, discovered that combining chemotherapy (temozolomide, TMZ) with a targeted therapy that blocks Notch signaling (γ-secretase inhibitor, GSI) blocks glioblastoma brain tumor recurrence in mice.  In patients, these tumors are typically treated with surgery, radiation and TMZ, but these therapies ultimately fail due to tumor recurrence.  GSIs are thought to block the cancer stem cells that resist chemotherapy/radiation and allow tumor recurrence.  The researchers hope to ultimately translate these findings into the clinic.  This study was published in the journal Cancer Research.
