Northwestern Medicine scientists have discovered two successful therapies that slowed the progression of pediatric leukemia in mice, according to three studies published over the last two years in the journal Cell, and the final paper published Dec. 20 in Genes & Development. When a key protein responsible for leukemia, MLL, is stabilized, it slows the progression of the leukemia, the most recent study found. The next step will be to combine the treatments from the past two years of research into a pediatric leukemia "super drug" to test on humans in a clinical trial.
The survival rate is only 30 percent for children diagnosed with MLL-translocation leukemia, a cancer that affects the blood and bone marrow. Patients with leukemia have a very low percentage of red blood cells, making them anemic, and have approximately 80 times more white blood cells than people without cancer.
