Rescuing mGPDH deficiency improves skeletal muscle regeneration during obesity and diabetes Rescuing mGPDH deficiency improves skeletal muscle regeneration during obesity and diabetes A–CImmunoblot (A, C) and IHC (B) of mGPDH and myogenin in GA muscles from obese patients (A, B) and the indicated mice (C).DqRT–PCR of mGPDH in GA muscle of the indicated mice at days 0 and 3 after CTX intramuscular injection.E–HExperimental setup (E, upper panel); qRT–PCR of mGPDH, myogenin, and myh3 (E, bottom panel); H&E staining (arrowhead, necrotic myofibers; asterisks, regenerating fibers) (F); distribution of the fiber CSA (G); and percentage of myofibers with central nuclei (H) in GA muscle from AAV‐mGPDH‐treated HFD‐fed mice at day 7 after CTX intramuscular injection.I–MExperimental setup (I and M, upper panels); qRT–PCR of mGPDH, myogenin, and myh3 (I, bottom panel); H&E staining (arrowhead, necrotic myofibers; asterisks, regenerating fibers) (J); distribution of the fibers CSA (K); percentage of myofibers with central nuclei (L); and muscle weight (M, bottom panel) in GA muscle from AAV‐mGPDH‐treated STZ‐treated mice at days 7 (I–L) and 14 (M) after CTX intramuscular injection.NImmunoblots of mGPDH, p‐AMPK, p‐ACC, PGC1α, and myogenin for the experiment described in (E).Data information: Data are presented as the mean ± s.e.m. Scale bars represent 200 μm in panel (B) and 100 μm (25 μm for magnification insets) in panels (F, J). In panels (A, B), obese patients (n = 11) and normal subjects (n = 18); in panels (C, D), n = 3 mice per group; in panels (E–L and N), n = 6 mice per group; in panel (M), n = 4 mice per group; in panels (B, F–H, and J–L), three sections were obtained per mouse. *P < 0.05, **P < 0.01, ***P < 0.001. Unpaired t‐test was used in panels (D, E, H, I, L, and M); the Wilcoxon test was used in panel (B); and the Kolmogorov–Smirnov test was used in panels (G, K).Source data are available online for this figure.
