Elevated levels of peripheral cytokines CXC ligand-10 (also called IP-10), TNFα, IL6, MIP-1α, and IFNγ were observed in plasma from EMT6 tumor-bearing mice 24 hours after receiving a single dose of dazostinag, with or without preceding radiation, and the cytokine levels returned to baseline within 120 hours. This evidence concerns the gene IL6 and neoplasm.
