Inhibiting the editing enzyme may provide a new therapeutic approach for blood cancers —

Cancer stem cells are like zombies — even after a tumor is destroyed, they can keep coming back. These cells have an unlimited capacity to regenerate themselves, making more cancer stem cells and more tumors. Researchers at University of California San Diego School of Medicine have now unraveled how pre-leukemic white blood cell precursors become leukemia stem cells. The study, published June 9 in Cell Stem Cell, used human cells to define the RNA editing enzyme ADAR1’s role in leukemia, and find a way to stop it. … Read the Full Story from the UC San Diego Newsroom
