MiR-218-5p played an essential role in the profibrotic effect

(A) Volcano plot of differential expression miRs in CTL-Exos and DCM-Exos. (B) miRNA screening assay. qRT-PCR results showed miR-218-5p mimics significantly upregulated expression fibrotic of markers (N= 3; one-way ANOVA; ∗ = p< 0.05).

(C) MiR-218-5p upregulated fibrotic marker in a dose-dependent manner.

(D) ANG II stimulation up-regulated miR-218-5p expression in DCM-iCMs (N= 3; ∗= p <0.05, ∗∗∗ = p< 0.001).

(E) Intracardial injection of miR-218-5p increased the fibrotic area in mouse hearts (N= 8, Student’s t test, ∗∗ = p< 0.01). Data represented as mean ± SD.
