Pathway analysis of persistent DEGs among the K, D, and AD groups.

<p>Red bars represent the persistently upregulated KEGG pathway enrichment significance levels, and green bars represent the persistently downregulated KEGG pathway enrichment significance levels (upper axis). The triangles denote the number of genes differentially expressed in the upregulated pathways, and circles denote the number of genes differentially expressed in the downregulated pathways (lower axis).
