Intramuscular fat content (IFC) and meat color are vital indicators of pork quality. A significant positive correlation between IFC and redness of meat color (CIE value) indicates that these two traits are likely to be regulated by shared molecular pathways.To identify candidate genes, hub genes, and signaling pathways that regulate these two traits, we measured the IFC and CIE value in 147 hybrid pigs, and selected individuls with extreme phenotypes for transcriptome analysis. The results revealed 485 and 394 overlapping differentially expressed genes (DEGs), using the DESeq2, limma, and edgeR packages, affecting the IFC and CIE value, respectively. Weighted gene co-expression network analysis (WGCNA) identified four modules significantly correlated with the IFC and CIE value. Moreover, we integrated functional enrichment analysis results based on DEGs, GSEA, and WGCNA conditions to identify candidate genes, and identified 47 and 53 candidate genes affecting the IFC and CIE value, respectively. The protein protein interaction (PPI) network analysis of candidate genes showed that 5 and 13 hub genes affect the IFC and CIE value, respectively. These genes mainly participate in various pathways related to lipid metabolism and redox reactions. Notably, four crucial hub genes () were shared for these two traits. After functional annotation of these four hub genes, we hypothesized that the axis could co-regulate lipid metabolism and the myoglobin redox response. Further research on these hub genes, especially the axis, will help to understand the molecular mechanism of the co-regulation of the IFC and CIE value, which will provide a theoretical basis for improving pork quality.
