Overcoming multidrug resistance in acute lymphoblastic leukemia cells

A strong predictor of poor outcome in children with acute lymphoblastic leukemia (ALL) is resistance to chemotherapy with glucocorticoids. Such resistance is caused, in part, by an inability of the leukemic cells to die by a process known as mitochondrial apoptosis. However, researchers have now identified a way to get round this block in mitochondrial apoptosis in glucocorticoid-resistant childhood ALL cells.
