AGT and cardiac hypertrophy: Furthermore, mice that develop angiotensin II-induced cardiac hypertrophy (TG1306/1R, TG), and dilated cardiomyopathy with aging [26], had increased expression of CAII, CAIV, and CAXIV, mRNA, in addition to elevated mRNA for low-activity secreted CAVI [27], suggesting that induction of carbonic anhydrases is a feature of cardiac hypertrophy.
