Muscle Transcriptome Analysis Reveals Molecular Pathways Related to Oxidative Phosphorylation Antioxidant Defense Fatness and Growth in Mangalitsa and Moravka Pigs

摘要

The study of gene expression at the transcriptome level provides rich information on the genes and metabolic pathways influencing relevant phenotypic traits. This study deals with the comparison of muscle transcriptome between two autochthonous pig breeds from Serbia (Mangalitsa and Moravka) as well as between Mangalitsa pigs fed a tannin-supplemented diet vs. a control one. The results provide a wide characterization of genes, pathways and potential regulatory mechanisms affecting muscle traits which differ among the experimental groups. The generated information improves the scientific knowledge on the cellular and metabolic basis of muscle growth, oxidative stability and fatness in pigs, and provides abundant candidate genes which could be responsible for phenotypic variation, and could be useful in future studies and selection approaches.
