Figure Lengend Snippet: Transcriptomics across muscle depots reveal metabolic shift from glycolytic toward oxidative (A) Experimental set up and color scheme used throughout and . (B) Fold changes of transcripts associated with fatty acid (FA) catabolism and transport as identified in supplementary Extended Data A in muscle of male mice ( n = 6) given ad libitum access to sulfur amino acid-restricted (SAAR) versus control (Con) diet for seven days. (C) Pathway enrichment analysis of genes showing significant diet-by-muscle interaction effects. (D) Fold changes (SAAR vs. Con) of TCA cycle genes in EDL and soleus. (E) Representative blots of electron transport chain complexes. (F) Quantification of relative protein abundance normalized to vinculin of SDHB for EDL and soleus ( n = 6) of male mice given ad libitum access to SAAR versus Con diet on day seven. (G) Representative blots of CD36, LPL, and PDK4 and vinculin ( top ) and quantification of relative protein abundance normalized to vinculin of CD36, PDK4, and LPL ( bottom ) in EDL ( n = 6) of male mice given ad libitum access to SAAR versus Con diet on day seven. (H) Representative blots of CD36, LPL, and PDK4 and vinculin ( top ) and quantification of relative protein abundance normalized to vinculin of CD36, PDK4, and LPL from blots ( bottom ) in soleus ( n = 6) of male mice given ad libitum access to SAAR versus Con diet on day seven. All panels represent data from mice that were not subjected to endurance running. All data are shown as mean, and error bars indicate SD unless otherwise noted; p values indicate the significance of the difference by Student t test between diets; significance is determined by p < 0.05.

Figure Lengend Snippet: SAAR increases muscle lipid flux without altering lipid pool sizes (A) Experimental design and color scheme used in A–3E and A. (B) Circulatory carbon flux ( n = 10–13) of 13 C 18 -U-Linolate of jugular-vein-catheterized male mice given ad libitum access to sulfur amino acid-restricted (SAAR) versus control (Con) diet for seven days. (C) Ex vivo β-oxidation measured by incorporation of 3 H-palmitic acid in 3 H-H 2 O in muscles of male mice fed a Con or SAAR diet for seven days ( n = 15). (D) Representative fluorescence images ( left ) of BODIPY 493:503 (green), WGA647 (red), and DAPI (blue) staining in EDL cross sections (scale bar, 50 μm) and quantification of Bodipy + Intensity within fibers ( right ) of male mice fed a Con or SAAR for seven days ( n = 6). (E) Lipidomics analysis from muscle of male mice fed a Con or SAAR diet for seven days ( n = 6), summarized as normalized ion counts of each main lipid class. (F) Experimental set up and color scheme used in G, 3H, and D–S3I. (G) Percent change in body weight ( n = 16) of male WT and EC CD36−/− mice given ad libitum access to SAAR versus Con diet after seven days. (H) Distance ran during a one-time maximal endurance test (n = 9–15) of male WT and EC CD36−/− mice given ad libitum access to SAAR versus Con diet on day seven. B–E represent data from mice that were not subjected to endurance running, G and H represent data from mice subjected to maximal endurance testing. All data are shown as mean, and error bars indicate SD unless otherwise noted; p values indicate the significance of the difference by Student t test between diets, or two-way ANOVA with Sidak multiple comparisons test between diets and muscle or genotype; significance is determined by p < 0.05.
