Delivery of tumor suppressor genes to reverse the malignant phenotype
1Department of Molecular Sciences, Central Research, Pfizer Inc, Eastern Point Road, Groton, CT 06340, USA
Abstract:
Despite early enthusiasm and excitement, the treatment of cancer via gene therapy is a long way from reaching fruition. The objective of this review is to describe the rationale as to why the delivery of genes encoding functional proteins whose activity has been lost during the initiation and development of cancer may be a feasible therapeutic option. In addition we will evaluate the limitations of the current delivery systems and discuss how these limitations have impacted upon the progress of gene therapy. Finally, we will describe and discuss the most recent attempts to deliver tumor suppressor genes to rodent models of human cancer and perhaps more importantly to human patients. As will become apparent during this review the excitement and enthusiasm for gene therapy remains high, however, this should not diminish the challenges that must be overcome before gene therapy becomes routine.
