Figure 4. GO analysis and protein–protein interaction (PPI) analysis. (A–C) GO enriched results revealed that these DEGs were involved in the biological process, molecular function, and cellular component and other functional pathways. Metascape bar graph to view the top twenty non-redundant enrichment clusters. The enriched biological processes were ranked by p value. A deeper color indicates a smaller p-value. Vertical axes represent different pathway. (D) Thirty-six proteins were related in the protein–protein interaction. GO, Gene Ontology; PPI, protein–protein interaction; DEGs, differentially expressed genes.
