Severe fibrosis and increased expression of NEAT1 in the left ventricular tissue of DCM patients. A–C Representative HE staining, PSR staining, and in situ hybridization results for Neat1 (scale bar = 20 µm; n = 6 in each group). F, G Quantitative polymerase chain reaction results for mRNA expression of Neat1 in the left ventricle (n = 6 in each group) or serum (n = 20 in each group) obtained from patients with DCM and control patients. Data are presented as mean ± SEM. **p < 0.01 vs. the normal group, ***p < 0.001 vs. the normal group
