Identification and analysis of differentially expressed genes (DEGs). a Volcano plot of all the genes. The dendrogram represents the cluster analysis of the 50 genes. b Heatmap plotted by the z-scores of the 50 most significantly differential expressed genes. c Gene set enrichment analysis of Gene Ontology (GO) among all the DEGs. BP: biological process; CC: cellular component; MF: molecular function. d Gene set enrichment analysis of Kyoto Encyclopedia of Genes and Genomes (KEGG) among all the DEGs. Gene ratio: the ratio of the enriched genes to the total number of genes in the relative pathway in the database
