Aortic caspase-1 activity (109, 83-155 relative luminosity units (RLU) versus 45, 38-64.5 RLU, p < .001, Figure 3(a)) and IL-1β concentration (15.67, 7.11-22.60 pg/mg protein versus 6.87, 4.54-11.60 pg/mg protein, p < .050, Figure 3(b)) were greater in aortic tissue samples of E-BAPN AAA mice compared with sham controls at day 90. Here, CASP1 is linked to triple-A syndrome.
