NR2F2 and cardiac hypertrophy: Moreover, Nr2f2 overexpression had no impact on cardiac hypertrophy but exacerbated fibrosis in DIHF mice and the fibrosis area of the AAV9-cTNT-Nr2f2-Con group was larger than that of AAV9-cTNT-ctrl-Con group (fibrosis area: 25.17 ± 2.843 vs. 19.37 ± 1.590) (Figures 1(f), 1(k), and 1(l)).
