Together with the hsa-mir-29b-3p and hsa-mir-29a-3p identified by gProfiler2, we mapped out these miRNAs on the gene-miRNA regulatory networks for the selected KEGG pathways relevant to the DMD-COs phenotypes: 1) Hypertrophy cardiomyopathy, 2) Dilated cardiomyopathy, 3) Arrhythmogenic right ventricular cardiomyopathy (ARVC), 4) PPAR signalling pathway (for adipogenesis), and 5) PI3K-Akt signalling pathway (for cardiac fibrosis (Table 5) (Qin et al., 2021)). This evidence concerns the gene AKT1 and arrhythmogenic right ventricular cardiomyopathy.
