(A) Schematic of RNAseq experimental design. (B) Heatmap showing 2253 significantly differentially expressed genes between P0, P7, and P15, categorized into four groups based on GO-biological process (BP) terms. (C, D) Top GO-BP terms for significantly upregulated and downregulated genes at P7 compared to P0 (P7 vs. P0). (E, F) Top GO-BP terms for significantly upregulated and downregulated genes at P15 compared to P0 (P15 vs. P0). Significant differentially expressed genes were obtained using a fold change cutoff of 2 and adjusted p-value≤0.05, in n=3 pigs per stage.
