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： 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.

摘要： A signaling pathway is identified that involves the activation of phospholipase A2 and protein kinase C in human cells, which in turn confers x-ray induction of the tumor necrosis factor &agr; (TNF) gene. Inhibition of phospholipase A2 abolishes radiation-mediated arachidonate production, as well as the subsequent activation of protein kinase C and TNF gene expression. These phospholipase A2 inhibitors may be used to ameliorate the adverse-effects of radiotherapy associated with TNF production.
