Differential expression of lncRNAs during aging process in fly gut. (A) Principal component analysis (PCA) plot of lncRNAs expression. Samples from different aging timepoints were presented with unique color. (B) Heatmap illustrating correlation of lncRNAs expression at various timepoints. (C) Volcano plot showing relative expression of lncRNAs in comparisons between different timepoints. Number of differentially expressed lncRNAs (DERs) were shown. The y-axis represents statistical significance as −log10 (adjusted p value), and the x-axis represents log2 fold change. Up-regulated lncRNAs were marked in red, down-regulated lncRNAs were marked in blue.
