CTSS deletion alleviated muscle microstructure repair in mice subjected to stress. a, b: Representative immunofluorescence images and quantitative data for the intensity of desmin protein expression in the four experimental groups at day 14 after stress (n = 5). Scale bar: 75 µm. c: Representative immunoblotting images and quantitative data for Desmin and GAPDH protein in the lysates from the four groups (n = 3). The data are mean ± SEM, and p-values were determined by a one-way ANOVA followed by Tukey’s post hoc tests (b). CW: CTSS^+/+ control mice, CK: CTSS^−/− control mice, SW: 14-day-stressed CTSS^+/+ mice, SK: 14-day-stressed CTSS^−/− mice. *p < 0.05; **p < 0.01; N.S, not significant
