MOLECULAR MEDICINE: Found in Translation.


ABSTRACT: Studies of the major hemoglobin disorders, ?-thalassemia and sickle cell disease (SCD), have laid a foundation for molecular medicine. While enormous progress has been made in understanding gene structure and regulation, translating molecular insights to therapy for the many individuals affected with these disorders has been challenging. Advances in three activities have recently converged to bring novel genetic and potentially curative treatments to clinical trials. First, improved lentiviral vectors for gene transfer into hematopoietic stem cells have revived somatic gene therapy for blood disorders. Second, elucidation of regulatory factors and mechanisms that control the normal developmental switch from fetal to adult hemoglobin has provided a route to reactivation of the fetal form for therapy. Third, revolutionary methods of gene engineering permit molecular insights to be leveraged for patients. Here I review how the promise of molecular medicine to bring transformative treatments to the clinical arena is finally being realized.
