Researchers discover a way to sensitize glioblastoma to chemotherapy

Brain cancer cells are particularly resistant to chemotherapy - toxins enter the cells, but before the toxins can kill, cancer cells quickly pump them back outside. In fact, brain cancer cells are even better than healthy cells at cleaning themselves. This means that when hit with chemotherapy, healthy cells tend to die before brain cancer cells. Especially in the brain, killing healthy cells is bad.
