[Future prospect of gene therapy for hereditary tumor]
14th Department of Internal Medicine, Sapporo Medical University, School of Medicine.
Abstract:
Gene therapy for hereditary tumor was discussed in two aspects: preventive and therapeutic approaches. A practical approach to prevention is the transfection of a wild type gene into presymptomatic lesions or normal tissue which may potentially give rise to malignant tumor. Preliminary trials of this approach have already been reported by several investigators. Therapeutic approach is much more difficult since metastasis generally occurs simultaneously at multiple sites and no appropriate delivery system for transgenes to target multiple lesions has been so far developed. We have most recently established a method by which transgenes can be specifically delivered to multiple-metastasized tumors via transferrin receptor and found this method to have successful therapeutic effects. The future direction of gene therapy for hereditary tumor was also addressed.
Insights
Gene therapy offers hope for hereditary tumors through prevention and treatment. A new method uses transferrin receptor to deliver genes to multiple tumors, showing successful therapeutic effects.
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Context:
- Hereditary tumors present significant challenges in both prevention and treatment.
