a The time course of AAV9-mediated TAK1 overexpression. Recombinant AAV9 vectors harboring TAK1 or GFP with a c-TnT promoter [3 × 1011 vector genomes/mouse] were injected into the tail veins of the mice 5 weeks before MI/R. b, c Representative infarct images obtained by Evans blue/TTC staining in each group. d Cardiac troponin-I (cTnI) levels in plasma 4 h after perfusion. e Cardiac creatine kinase-MB (CK-MB) levels in plasma 4 h after perfusion. f, g Western blot images and quantitative analysis of p-TAK1, TAK1, p-p38, p38, p-JNK, JNK, Bcl-2 and Bax protein expression in ischemic myocardial tissue. The data are shown as the mean ± SEM (n = 6 for each group). #P < 0.05 and ##P < 0.01 vs. the MI/R + AAV9-cTnT-GFP group. $P < 0.05 and $$P < 0.01 vs. the MI/R + AAV9-cTnT-GFP + NG-R1 group.
