Abstract
We report that tumor necrosis factor alpha (TNF-alpha) mRNA is increased after treatment with x-rays in certain human sarcoma cells. An increase in TNF-alpha mRNA is accompanied by the increased production of TNF-alpha protein. TNF-alpha enhances radiation lethality in both TNF-alpha-producing and -nonproducing tumor cells. These data suggest that, in addition to the direct cytotoxic effects of x-rays, production of TNF-alpha may add to radiation lethality through autocrine and paracrine mechanisms. Combinations of TNF-alpha and therapeutic radiation may be useful in clinical cancer therapy.Entities:
