Volcano plots and Venn diagrams of differentially expressed genes. a Volcano plots of GSE62232. b Volcano plots of GSE121248. Each colored dot represents an up or downregulated gene, where blue indicates genes with low levels of expression, red indicates genes with high levels of expression, and gray indicates genes with no differential expression based on the criteria of P< 0.05 and |log FC| > 2. c 27 DEGs were upregulated in the two datasets (logFC> 0). d 89 DEGs were downregulated in two datasets (logFC< 0). Different color meant different datasets
