The expression levels of 10 angiogenesis-associated genes (ANGPT1, ANGPT2, FGF2, PDGFA, PDGFB, TGFA, TGFB1, VEGFA, VEGFB, and VEGFC) and 8 inflammation-related genes (CCL2, CCL5, CSF2, CXCL8, IL1A, IL1B, IL6, and TNF) were analyzed in peripheral blood mononuclear cells (PBMC) of 40 patients with AAA (AAA group) and 24 healthy controls (control group) using the RT-qPCR method. The gene discussed is VEGFB; the disease is triple-A syndrome.
