Gene Therapy: A New Approach for Treatment of Cancer.
The identification of critical genes that encode for regulatory proteins has helped elucidate the molecular mechanisms that govern cell proliferation and malignant transformation. Several approaches to gene therapy for cancer have been described. These include the use of fibroblasts expressing suicide genes, restoration of expression of tumor suppressor genes, cytokine gene therapy, genetic modification of T lymphocytes, and protection of normal hemopoiesis in cancer patients. Clinical trials are underway in all these areas.
