Fig. 5.

The functional enrichment analysis of gene sets that drive the regulation of protein abundance. a, b The overall distribution of the gene importance in predicting protein abundance are shown in a breast and b ovarian cancers. c, d Functional enrichment analysis was performed on gene subsets based on the feature importance. The colors represent the major KEGG categories. Genes that play more important roles in regulating protein abundance are mainly associated with “Metabolism”
