Corroborating our results on the mRNA level, protein expression of KAT2B, KAT3B, and KAT6B was significantly higher in AAA tissue compared to the protein expression in healthy control aortae (4.1-fold, 2.8-fold, and 2.2-fold, P < 0.001, <0.001, and 0.033, respectively; see Fig. 2). The gene discussed is KAT6B; the disease is triple-A syndrome.
