Figure 2. Proliferation is the major driver of tissue specificity in tRNAs.

Figure 2

  1. Medians of square‐root‐normalized tRNA abundances across all TCGA tissues. The color of the tissue labels corresponds to the average Ki67 expression. Refer to Table EV4 for full cancer type names and number of samples.
  2. Principal component analysis (PCA) of the relative anticodon abundances (RAA, see Materials and Methods) of all healthy samples of TCGA, where the color scale corresponds to the mean tissue expression of Ki67. The Spearman correlations of Ki67 with the components are shown, as well as the samples of most extreme tissues.
  3. Top positive and negative GO terms upon gene set enrichment analysis (GSEA) of the correlations of the first PCA component against all genes.
