LncRNA PVT1 knockdown suppresses I/R-induced apoptosis and Caspase1 involving pyroptosis in myocardial tissues. (A–D) Western blot of the expression of (B) Cleaved caspase-3, (C) Bax, and (D) Bcl-2 proteins in myocardial tissues of five groups: control, sham, I/R, I/R + sh-NC, and I/R + sh-PVT1 groups. Mice in the I/R + sh-NC and I/R + sh-PVT1 groups were injected by 10 μL sh-NC or sh-PVT1 via Lipofectamine 2000 reagent. After 48 h, myocardial I/R model was constructed. No treatment was done for mice in the control group. The chest of mice in the sham operation group was only opened, but was threaded the corresponding part without ligating the LAD. There were 10 mice in each group. (E,F) Immunohistochemistry of the expression of Caspase1 protein in myocardial tissues of above groups. Bar = 100 μm. Arrow highlights the positive staining of Caspase1. *p < 0.05; **p < 0.01; ****p < 0.0001.
