FIG. 1.

Monoamine oxidase-A (MAO-A) activity is increased in response to hypertrophy, failure, and aging in the heart. (A) MAO-A activity in cardiac homogenates from rats with ascendant aortic banding (Band) for 5 weeks (hypertrophy, n=5) or 15 weeks (heart failure [HF], n=5) compared to age-matched sham (n=5). (B) MAO-A activity in cardiac homogenates from young (2 months), middle age (12 months), and senescent rats (24 months) (n=6). (C) MAO-A activity in isolated rat cardiomyocytes at the ages indicated (n=3–4). (*p<0.05, **p<0.01, ***p<0.001 vs. indicated value).
