title: Gene transfer: a review of methods and applications.
abstract: Gene transfer is a potentially powerful tool for the treatment of a wide variety of diseases. The transfer of these genes is achieved by utilizing a variety of vectors, including retroviral, adenoviral, adeno-associated virus (AAV) and a number of non-viral mechanisms. Numerous studies have successfully demonstrated transduction of genes into target cells with a variety of vectors, and have provided 'proof-in-principle' that gene transfer can result in prolonged in vivo expression of transduced genes, albeit at low quantities. Furthermore, gene marking studies in acute myeloblastic leukemia (AML), chronic myeloid leukemia (CML) and neuroblastoma have elegantly demonstrated that gene-marked tumor cells contribute to relapse following autologous transplantation. However none of the studies examining the therapeutic benefit of gene therapy has definitively demonstrated a clinically meaningful benefit. Nonetheless, the results of studies involving gene transfer for severe combined immunodeficiency (SCID), chronic granulomatous disease (CGD), melanoma and lung cancer highlight the potential benefit of this strategy. This review will discuss mechanisms of achieving gene transfer into target cells. It will examine some of the pre-clinical and clinical results to date and will discuss some of the potential uses of gene transfer for therapeutic purposes.
