We evaluated the percentage of live cells positive for HIF-1α via flow cytometry, and compared to controls, we observed increased HIF-1α expression in CaPO4 (0.1294% ± 0.01719% vs. 1.774% ± 0.2277%, p < 0.01) (Figure 5A) and AngII (0.7133% ± 0.08819% vs. 3.703% ± 0.5235%, p < 0.01) (Figure 5B) mouse models of aneurysm. This evidence concerns the gene AGT and aneurysm.
