Article Title: Globin gene transfer: A paradigm for transgene regulation and vector safety
Abstract: The β-thalassemias and sickle cell disease are severe congenital anemias that are caused by the defective synthesis of the β chain of hemoglobin. Allogeneic hematopoietic stem cell (HSC) transplantation is curative, but this therapeutic option is not available to the majority of patients. The transfer of a regulated β-globin gene in autologous HCSs thus represents a highly attractive alternative treatment. This strategy, simple in principle, raises major challenges in terms of controlling transgene expression, which ideally should be erythroid-specific, differentiation stage-restricted, elevated, position-independent, and sustained over time. Using lentiviral vectors, we recently demonstrated that an optimized combination of proximal and distal transcriptional control elements permits lineage-specific and elevated expression of the β-globin gene, resulting in therapeutic hemoglobin production and correction of anemia in β-thalassemic mice. Several groups have now confirmed and extended these findings in various mouse models of severe hemoglobinopathies, thus generating enthusiasm for a genetic treatment based on globin gene transfer. Furthermore, globin vectors provide a paradigm for improving vector safety by restricting transgene expression to the differentiated progeny within a single lineage, thereby reducing the risk of activating oncogenes in hematopoietic progenitors. Here we review the principles underlying the genesis of regulated vectors for stem cell therapy.
