Using a diameter expansion of 50% compared with the control as the definition for AAA, hyperuricemia also significantly increased the incidence of AAA formation (control, 0% (0/10); hyperuricemia, 20% (2/10); Ang II, 60% (6/10); and hyperuricemia + Ang II, 90% (9/10); n = 10, P < 0.05, Fig. 2D). The gene discussed is AGT; the disease is triple-A syndrome.
