Abstract
We have developed an integrasedefective lentiviral LV vector in combination with a genetargeting approach for gene therapy of βthalassemia The βglobin genetargeting construct has two homologous stems including sequence upstream and downstream of the βglobin gene a βglobin gene positioned between hygromycin and neomycin resistant genes and a herpes simplex virus type 1 thymidine kinase HSVtk suicide gene Utilization of integrasedefective LV as a vector for the βglobin gene increased the number of selected clones relative to nonviral methods This method represents an important step toward the ultimate goal of a clinical gene therapy for βthalassemiaAs gene therapy for βthalassemia using lentiviral vectors may not be acceptable because of unpredictable side effects identifying a solution that combines an efficient delivery of desired nucleic acids sequences with a homologous recombination mechanism has been pursued
