The expression of VEGF-A, bFGF, TGF-β, MCP-1, MMP-9, TSP-1, TIMP-2, and endostatin was significantly higher in AT than in normal liver or TT (p < 0.01 and 0.05, respectively), while no significant difference was found in the levels of TIMP-1, COX-2, and NOS-2 between TT and AT. This evidence concerns the gene CCL2 and ataxia telangiectasia.
