Global gene expression profiles of porcine peripheral blood during development. Principal component analysis (PCA) plot of (A) mRNAs and (B) lncRNAs performed based on log2-transformed fragments per kilobase of transcript per million mapped reads (FPKM) values. The FPKM value of mRNA and lncRNA were transformed by log₂ (FPKM+1). lncRNAs, long noncoding RNA. This information was used to draw heatmaps with hierarchical clustering. Heatmaps for hierarchical clustering (C: mRNA, D: lncRNA).
