Figure Lengend Snippet: Fig. 4 Simultaneous deletion of MuRF1 and MuRF2 causes decreased protein expression of myogenic factors and increased apoptosis. (a) Western blots for Myogenin, Myf‐5, FHL2, MARP2 and GAPDH in TA of MuRF1&2 dKO animals 3 and 10 days after CTX injury and silver staining showing even protein loading. Fluorescence images showing apoptotic nuclei by TUNEL assay in WT (b‐d and h‐j) and MuRF1&2 dKO (e‐g and k‐m) muscles 3 (b‐g) and 10 (h‐ m) days after CTX injury. Images were obtained with a fluorescence microscope and a 40x air medium objective. Bar, 30 µm. (n) Percentage of apoptotic nuclei in WT and MuRF1&2 dKO muscles 3 and 10 days after CTX injury
