The relative amounts of LRG1 (iTRAQ ratio = 1.99, postsurgical vs. presurgical) and fibronectin (iTRAQ ratio = 0.69, postsurgical vs. presurgical) for AAA patient #AAA2 (Figures 2A,B,C,F) and LRG1 (iTRAQ ratio = 2.24, postsurgical vs. presurgical) and fibronectin (iTRAQ ratio = 0.63, postsurgical vs. presurgical) for TAA patient #TAA4 (Figures 2A,B,D,G) in postsurgical sera compared with those in presurgical sera were examined by Western blot analysis. This evidence concerns the gene LRG1 and triple-A syndrome.
