Experimental details: Figure 3 LAT1 protein increases per skeletal muscle fiber with resistance exercise training but the increase in protein is not located on the membrane. The fold change from PRE, designated as the dashed line at 1.00, for Total LAT1 (A) , Total LAT1 per fiber (B) , Membrane LAT1 (C) , and Membrane LAT1 per fiber (D) protein content for each group using immunohistochemistry. A representative image showing green-stained dystrophin and red-stained LAT1 protein using 20x magnification (E) ; the inset in E is magnified using 40x magnification (F) and the arrows point toward LAT1 protein. The scale bar in both images is 100 mum. *A significant effect. Data are represented as mean +- standard deviation. Sample size for each group is PLA = 10, LEU = 9, and WPC = 9.

( A ) Timeline of the myogenic specification from human ePSCs to MPCs and myotubes with markers for each specific stage. ( B ) Secondary differentiation of MPCs into myotubes. Experiments are analyzed at 0 hours (MPCs in skeletal muscle cell growth medium) and at 24, 48, and 120 hours after switching to secondary differentiation medium. ( C ) Representative immunocytochemistry images of PAX7, MYOD1, dystrophin, MYH (MF20), and titin in DMD-R3381X and CORR-R3381X myogenic cultures at 120 hours of secondary differentiation. Enlarged images of titin demonstrate sarcomere striation. Scale bars, 100 mum. ( D ) Immunoblotting confirms that full-length dystrophin (427 kDa) is restored in CORR-R3381X myogenic cultures. ( E ) Quantification of PAX7-positive, MYOD1-positive, and MF20-positive cells and fusion index during secondary differentiation at 0, 24, 48, and 120 hours in DMD-R3381X and CORR-R3381X cultures.

Experimental details: Fig. 3. Reduced mass and myofiber area in Sgcg 521DeltaT mice. (A) Body mass was not significantly different among genotypes. (B) Gluteus/hamstring (GH) muscle mass normalized to tibia length was reduced in 521DeltaT mice compared with controls. (C) The total mass from muscle groups normalized to tibia length was significantly reduced in 521DeltaT mice compared with WT controls (quadriceps, gluteus/hamstring, triceps, diaphragm, heart, tibialis anterior muscle groups combined). (D) Average myofiber cross-sectional area (CSA) was significantly smaller in 521DeltaT mice than in WT controls. (E) Percentage of myofibers with >1 internal nuclei was increased in 521DeltaT muscle, with 4-month-old 521DeltaT myofibers having the most internal nuclei. (F) Representative images of 521DeltaT and WT muscle. Anti-dystrophin (green) outlined myofibers. Hoechst (blue) demonstrated nuclei. Data are mean+-s.e.m. * P =5 mice per group). Scale bars: 50 um.
