α-SMA immunofluorescence of cardiomyocytes. (A): α-SMA immunofluorescence showing images of SLC26A4-transfected H9C2 cardiomyocyte hypertrophy model. Nuclei were stained with DAPI (blue), α-SMA staining (green) was used to measure the relative cell surface areaThe scale bar is 10 μm. (B): Statistical analysis of α-SMA protein expression levels. (*P < 0.05, **P < 0.01, ***P < 0.001 vs. normal group; Results were analyzed by one-way ANOVA).
