Functional enrichment analysis of Cthrc1 -correlated genes. (A) Top 20 Gene Ontology biological processes (GO-BPs) significantly enriched by Cthrc1 -correlated genes. (B) Top 2000 Cthrc1 -correlated genes were analyzed using the Metascape tool ( https://metascape.org/ ) to explore the relationships between the GO-BP terms. The nodes represent enriched GO-BP terms and are colored by their respective cluster IDs, whereas the edges link similar terms. The most significant term of the cluster is displayed as a label to represent that cluster. The Metascape tool employs a heuristic algorithm to select the most informative terms from the GO clusters. It samples 20 top-score clusters, selects up to the 10 best-scoring terms (lowest p -values) within each cluster, then connects all term pairs with Kappa similarity above 0.3. (C) Top 20 mammalian phenotype ontologies and (D) Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathways significantly enriched by the Cthrc1 -correlated genes.
