ABSTRACT
Inflammatory molecules (IMs) play an important role in ionizing radiation (IR)-induced soft tissue damage. The alteration of IMs as a function of time was studied with a protein array containing 62 IMs in mouse cutaneous soft tissues exposed to 30 Gy. The results showed that (1) 2 days after irradiation, the levels of TGF-ß1, MIP-1γ, IL-1α, and sTNF RI increased, while IGFBP-3, CXCL16, and IL-1ß decreased in IR skin as compared to control skin; (2) 21 days after IR, TGF-ß1, and MIP-1 γ, IL-1α remained high, while CXCL16 and IL-1ß remained low; (3) 3 months after IR, the cytokine pattern exhibited reversals. The levels of MIP-1γ decreased, while VCAM-1, IGFBP-3, and TGF-ß1 production increased. The data indicated that (a) IMs change as a function of time after soft tissue irradiation; (b) changing IM levels may reflect the altered balance of the cytokine network, leading to imbalance or homeostasis; and (c) an antibody-based protein array can be used to assess multiple IMs simultaneously, making it useful for bulk screening for changes in tissue cytokine levels.
