Quantitative analysis of myocardial sections demonstrated significant accumulation of perivascular fibrosis (control vs. Mst1: 2.7 ± 0.2 vs. 12.3 ± 0.3%, p < 0.001) and interstitial fibrosis (control vs. Mst1: 0.2 ± 0.1 vs. 4.1 ± 0.1%, p < 0.001) in cardiomyopathy mice as represented in Figure 1. This evidence concerns the gene MST1 and cardiomyopathy.
