Bar = 200 and 100 μm, respectively. Magnification = ×20. b, c Fibrotic area quantification of stained sections. d Correlation analysis between PicroSirius positive area and the slope of EDPVR. e–g Quantitative real-time PCR was conducted to detect the mRNA expression of Fibronectin-1, Collagen-1, and TGF-β in the myocardium. Values are expressed as the mean ± SD. n = 8 per group. *P < 0.05, **P < 0.01 vs. Lean; #P < 0.05 vs. ZDFBack to article page
