Functional enrichment analysis of key genes. (A) Heat maps showing enrichment of key genes. Length of bars represent ${log}_{10}\left(P\right)$ based on the best-scoring term within each cluster, the color key from shallow to deep indicates high to low P values, respectively. (B) Enrichment network of these genes. Each term is indicated by a circular node. The number of these genes falling into that term is represented by the circle size and the nodes of the same color belonged to the same cluster. (C) Circos plots of these key genes. The related genes are linked by lines.
