AB  - In this study, we aimed to use duck breast muscle and leg muscle, the 2 main 
      productive muscle organs, as a model to elucidate the molecular mechanism 
      controlling how the 2 muscles have different deposition capabilities, and to 
      analyze the mechanisms facilitating duck muscle development posthatching. Peking 
      duck breast muscle and leg muscle were collected 3, 7, and 16 wk posthatching. 
      The morphology of the myofibers was observed by paraffin sectioning the muscles. 
      The expression of genes involved in protein metabolism [mammalian target of 
      rapamycin (mTOR), RPS6-p70-protein kinase (S6K), forkhead box O1 (FoxO1), muscle 
      RING finger 1 (MuRF1), and atrogin-1 (MAFbx)] was detected using real-time 
      quantitative PCR and Western blot assays, and the results indicated that breast 
      muscle had a stronger capacity for both protein synthesis and protein degradation 
      compared with leg muscle. Satellite cell frequency declined during muscle 
      development in both tissues, and the expression of Pax3/7, satellite cell marker 
      genes, was not significantly different between breast muscle and leg muscle. No 
      notable apoptosis was observed in either tissue. The results of this study 
      suggest that protein metabolism signaling is the main reason promoting duck 
      skeletal muscle mass gain.
