A QRT-PCR analysis of circSNRK in AAV9 ctrl and AAV9 circSNRK treated rat hearts. ***p < 0.001 vs. AAV9 ctrl group. B Echocardiography analysis was performed at 1day,14days and 28 days after establishment of MI. And quantitative analysis of LVEF and LVFS in the AAV9 circSNRK and AAV9 ctrl groups. ***p < 0.001 vs. Sham + AAV9 ctrl group; #p < 0.05, ##p < 0.01 vs. MI + AAV9 ctrl group. (n = 5–6 for each group). C HE staining images at the border zone 28 days after MI. bar = 25 µm. D Triphenyltetrazolium chloride (TTC) staining of rat ventricular cross-sections at 28 days post-MI, ***P < 0.001 vs. Sham + AAV9 ctrl, ###P < 0.001 vs. MI + AAV9 ctrl. (n = 5 for each group). E Masson staining images at 28 days after MI and quantitative analyses of infarct size. Red, myocardium; blue, scarred fibrosis. ***p < 0.001 vs. MI + AAV9 ctrl group. ###P < 0.001 vs. MI + AAV9 ctrl. (n = 5–6 for each group).
