Reactivating the fetal globin gene Mutation of adult-type globin genes causes sickle cell disease and thalassemia. Although treating these hemoglobinopathies with gene therapy is possible, there is a pressing need for pharmacologic approaches to treat general patient populations. One promising approach is to reactivate repressed expression of fetal-type hemoglobin (HbF) in adult erythroid cells. Masuda et al. reveal a molecular mechanism governing HbF repression as mediated by the LRF/ZBTB7A transcription factor. The study may encourage the development of new HbF reactivation therapies for hemoglobinopathies. Science , this issue p. 285
