Comparative Transcriptomic Analysis Between High- and Low-Growth-Rate Meat-Type Rabbits Reveals Key Pathways Associated with Muscle Development.
Rabbit meat constitutes a high-protein, low-fat nutritional resource demonstrating rising consumption, particularly within the Asia-Pacific region. Consequently, muscle growth and developmental pattern in meat rabbits represent critical economic considerations. To elucidate the primary signaling pathways governing muscle development, we first performed comparative body weight analyses between two rabbit breeds exhibiting divergent growth rates: the fast-growing Checkered Giant (Ju) and slow-growing Sichuan Ma rabbit. Subsequent, post-natal qualities of thigh and longissimus dorsi muscle fiber were quantified across three developmental phases (28, 56, and 84 days post-natal). The results showed the body weight of Ju rabbit was significantly higher than that of Ma rabbit beyond 3 weeks post-natal (p < 0.05), while Ma rabbit exhibited larger muscle fiber areas in both tissues at 56 days (p < 0.05). The transcriptome analysis showed that 284 and 305 differentially expressed genes (DEGs) (|log2FC| > 1, padj < 0.05) were identified in thigh muscle and longissimus dorsi muscle, respectively. GO (Gene Ontology) analysis of DEGs indicated DEGs in the thigh muscle were enriched in these terms related to biological processes of muscle cell migration and smooth muscle cell migration, cellular components of sarcomere, myofibril, and actin filament bundle, while DEGs in longissimus dorsi muscle were enriched in these terms associated with biological processes of muscle cell migration, smooth muscle cell migration and muscle structure development, cellular component of actin cytoskeleton, contractile fiber, myofibril, myosin complex and molecular function of actin filament binding. Integrated GO, KEGG and PPI analyses of co-expressive DEGs implicated the HIF-1 signaling pathway and Glycolysis/Gluconeogenesis in muscular development. Different expression of energy metabolism hub-genes might be the primary reason for interbreed muscle developmental disparities.

期刊介绍：
Animals (ISSN 2076-2615) is an international and interdisciplinary scholarly open access journal. It publishes original research articles, reviews, communications, and short notes that are relevant to any field of study that involves animals, including zoology, ethnozoology, animal science, animal ethics and animal welfare. However, preference will be given to those articles that provide an understanding of animals within a larger context (i.e., the animals'' interactions with the outside world, including humans). There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental details and/or method of study, must be provided for research articles. Articles submitted that involve subjecting animals to unnecessary pain or suffering will not be accepted, and all articles must be submitted with the necessary ethical approval (please refer to the Ethical Guidelines for more information).
