Dynamic expression profiles of mRNAs and lncRNAs during porcine postnatal pineal development. (A) Pearson correlation plot for the pineal transcriptome of Y30, Y180, and Y300, with three replicates for each developmental stage. (B) Principal component analysis of the pineal samples across three postnatal developmental stages based on both mRNA and lncRNA expression levels. Stages are illustrated by different shapes and colors. The x- and y-axes represent the first and second PC, respectively, with the percent variance explained by each PC in parentheses. (C) Hierarchical clustering analysis of the nine pineal samples across three developmental stages based on both mRNA and lncRNA expression levels. (D) Top enriched GO biological process terms of the highly expressed genes in the pineal gland. (E) The expression of TTR gene in postnatal pineal gland. (F) Heatmap showing the expression of homeobox transcription factors during postnatal pineal development.
