Fig. 5From: RETRACTED ARTICLE: Bone Marrow Mesenchymal Stem Cell-Derived Exosomal MicroRNA-133a Restrains Myocardial Fibrosis and Epithelial–Mesenchymal Transition in Viral Myocarditis Rats Through Suppressing MAML1Elevated exosomal miR-133a reduces the mRNA expression of collagen I, collagen III, TGF-β1 and CTGF in myocardial tissues of rats with VMC. A Collagen I mRNA expression in myocardial tissues of rats was detected by RT-qPCR; B Collagen III mRNA expression in myocardial tissues of rats was detected by RT-qPCR; C TGF-β1 and CTGF mRNA expression in myocardial tissues of rats was detected by RT-qPCR. *P < 0.05; **P < 0.001Back to article page
