A Immunoblots showing protein levels of NLRP3 (A1, A2), ASC (A1, A3), cleaved caspase-1 (A1, A4), and GSDMD-N (A1, A5) in the indicated groups. B Percentage of TUNEL-positive cells in the indicated groups. C Proportion of heart to body weight in the indicated groups. D Quantification of the cross-sectional area of cardiomyocytes of the left ventricle in the indicated groups. E Quantification of the myocardial fibrosis in the indicated groups. F Quantitative analysis of left ventricular EF in the indicated groups. G Immunoblots showing protein levels of NLRP3 (G1, G2), ASC (G1, G3), cleaved caspase-1 (G1, G4), and GSDMD-N (G1, G5) in the suitably treated cardiomyocytes. H Percentage of PI-positive cells in the suitably treated cardiomyocytes. I Measurement of the cell surface area of cardiomyocytes in the indicated groups. mRNA expression of cardiac hypertrophy markers BNP (J) and β-MHC (K) in the suitably treated cardiomyocytes. Results are presented as the mean ± SEM, n = 6. P < 0.01 compared to control, #P < 0.01 compared to TAC group or Ang-II group.
