Abstract:
Recently, remarkable advances have been achieved in molecular and genetic researches of different kinds of general diseases, as well as in basic and clinical studies using gene therapy for central nervous system diseases. For brain tumors, clinical trials have been already started in more than 10 clinical protocols and more than 100 patients with malignant brain tumors. Nevertheless, there are still major issues that remain to be resolved for achieving better clinical results, such as delivery system of genetic material, regulatory methods of the intracellular expression of the transgene, antitumor efficacy, and tumor selectivity. In this paper, molecular genetic studies and the current state of gene therapy for neurological diseases, especially brain tumors, are described, and the future direction of this fascinating approach is discussed.
