AGGF1 and myocardial infarction: The size of cardiac fibrotic areas reflecting the size of the infarct areas was increased by MI, but AGGF1 treatment dramatically reduced the infarct size (22.54% ± 1.25% for AGGF1 treatment versus 50.94% ± 7.74% for IgG treatment, p < 0.01) (bottom panel, S13 Fig).
