摘要: The invention provides methods of screening to identify compounds that modulate the ability of a protein to translocate to the mitochondria when a cell is subjected to cellular stress. Such compounds can be useful to modulate the level of apoptosis in a cell. For example, compounds identified according to the methods described herein can be used to treat disorders characterized by excessive apoptosis, e.g., a neurological disorder, or insufficient apoptosis, e.g., cancer.

摘要: Treatment of cells with ionizing radiation is associated with the production of arachidonic acid. Inhibition of phospholipase A2 abolishes radiation-mediated arachidonate production, protein kinase C induction and tumor necrosis factor gene expression. The addition of inhibitors of lipoxygenase, such as ketoconazole, prior to irradiation reduces the expression of of tumor necrosis factor while maintaining the expression of other radiation inducible genes, such as Egr-1 and c-jun. In contrast, indomethacin, an inhibitor of cyclooxygenase, enhanced the expression of tumor necrosis factor as well as other radiation inducible genes. The results show that lipoxygenase inhibitors are useful in the treatment of radiation-induced mucositis, dermatitis, pneumonitis, proctitis, and esophagitis. which may be due to the production of cytokines such as TNF.

摘要: The present invention provides for improved vectors for use in gene therapy. Utilizing the cancer specific DF3/MUC1 promoter to drive a replication essential gene, vectors are made conditionally replication-competent, permitting wider infection and expression of tumor cells. In addition, therapeutic genes and adjunct therapies further increase anti-tumor efficacy.

摘要: This invention relates to genetic constructs which comprise an enhancer-promoter region which is responsive to radiation, and at least one structural gene whose expression is controlled by the enhancer-promoter. This invention also relates to methods of destroying, altering, or inactivating cells in target tissue by delivering the genetic constructs to the cells of the tissues and inducing expression of the structural gene or genes in the construct by exposing the tissues to ionizing radiation. This invention is useful for treating patients with cancer, clotting disorders, myocardial infarction, and other diseases for which target tissues can be identified and for which gene expression of the construct within the target tissues can alleviate the disease or disorder.
