The expression levels of 18 genes associated with angiogenesis and inflammation (ANGPT1, ANGPT2, CCL2, CCL5, CSF2, CXCL8, FGF2, IL1A, IL1B, IL6, PDGFA, PDGFB, TGFA, TGFB1, TNF, VEGFA, VEGFB, and VEGFC) were analyzed in the following comparisons: LEAD vs. AAA, LEAD vs. VV, and AAA vs. VV. This evidence concerns the gene PDGFB and triple-A syndrome.
