Figure Lengend Snippet: CoO-TRIM increased myofibers with centrally nucleated myofibers (CLN) and modulated proteolytic activity. ( A ) Representative images of TA muscle cross-sections at 14 dpt. Laminin (white): basal laminae; DAPI (blue): nuclei. Yellow arrows depicting position of central nuclei. ( B ) Summary values ( n = 4–5/group) for total myofibers with CLN normalized to TA muscle cross-section area (mm 2 ) at 14 dpt. ( C ) Summary values ( n = 4–5/group) for total myofibers (CLN + + CLN − ) normalized to TA muscle cross-section (mm 2 ) at 14 dpt. ( D ) Representative immunoblot for αII-Spectrin. The 145 kDa cleavage byproduct was normalized to total protein per lane, represented by the 40 kDa band from the total protein stain, and analyzed as a ratio of the 250 kDa band of αII-Spectrin. Mean densitometric data revealed a significant reduction in cleaved αII-Spectrin abundance in TA muscles of D2. mdx TRIM mice at 14 dpt. ( E ) Representative immunoblot of LC3B II and mean densitometric data at 14 dpt revealed reduced autophagosome number following CoO-TRIM administration in D2. mdx mice. ( n = 5/group); Summary values are means ± SEM. Comparisons made vs. WT and vehicle controls by 2-Way ANOVA, p < 0.05 = significant. Scale bars = 100 µm.

Figure Lengend Snippet: Comparison of CLN in myofibers of WT and D2. mdx treated with Saline and TRIM mice. ( A , E ) Representative images of TA muscle cross-sections at 70 dpt and 140 dpt. Laminin (white): basal laminae; DAPI (blue): nuclei. Yellow arrows identify position of central nuclei. ( B , F ) Summary values for total myofibers with CLN (Top) and total myofibers (CLN + + CLN − ) (Bottom) normalized to TA muscle cross-section area (mm 2 ). Summary values presented for ( B ) 70 dpt and ( F ) 140 dpt. ( n = 7–8/group); scale bars = 100 µm. Proteolytic activity is altered following CoO-TRIM treatment. ( C , G ) Representative immunoblots for αII-Spectrin. The 145 kDa cleavage byproduct was normalized to total protein per lane, represented by the 40 kDa band from the total protein stain, and analyzed as a ratio of the 250 kDa band of αII-Spectrin. Mean densitometric data revealed a significant reduction in cleaved αII-Spectrin abundance in TRIM mice at 70 dpt. There was no difference at 140 dpt. ( D , H ) Representative immunoblots of LC3B II and mean densitometric data at ( D ) 70 dpt, revealed that TRIM reduced autophagosome number. No differences were observed at ( H ) 140 dpt. ( n = 7–8/group); summary values are means ± SEM. Comparisons made vs. vehicle controls by two-tailed Student’s t -test; p < 0.05 = significant.
