Differential expression analysis and function enrichment. (A), volcano plot of differentially expressed genes. The blue dots represent down-regulated genes, red dots represent up-regulated genes and grey dots represent the genes without significant expression changes between meningiomas and normal gorups; (B), the principal component analysis of all samples shows the significant differences between these two groups; (C), heatmaps of differentially expressed genes. The light blue and pink blocks in the top represent normal and meningiomas samples, respectively. The Y-axis represent all the differentially expressed genes; Bubble diagrams show the significantly enriched gene ontology annotation terms (D) and KEGG pathways (E). The size of bubbles represent the count of genes, and thre color from red to blue represent the P value from samll to large
