The effect on skeletal muscle fibre type switching and mitochondrial damages in sarcopenia animal models.

(A) Immunofluorescence staining and quantification for fibre types in GA muscle sections. Blue: type I; green: type IIA; red: type IIB; black: type IIX staining (B–C) Mitochondrial DNA damage detection. n ​= ​5 per group Quantitative data are presented as mean ​± ​SD. Statistical analyses are performed using one-way ANOVA test, with significance set at P ​< ​0.05 (∗:P ​< ​0.05, ∗∗:P ​< ​0.01, ∗∗∗:P ​< ​0.005, #:P ​< ​0.001).
