CD9 is highly expressed in tumor groups. (a) GSE16011 database showed that CD9 mRNA expression in tumor tissues was higher than that in normal tissues; (b) Validation set GES68848 showed that CD9 mRNA expression in tumor tissues was higher than that in normal tissues. (c) TCGA database indicated that CD9 mRNA expression was high in patients older than 65 years-old, male, IDH wild type, and receiving radiotherapy; (d) CGGA database indicated that the expression level of CD9 was WHO4 > WHO2 > WHO3, and CD9 mRNA was highly expressed in patients with IDH wild type and X1p19q without co-deletion; (e) CGGA database indicated that patients with glioma with high expression of CD9 had lower OS; (f) Area under ROC curve (AUC) = 0.785, indicating that CD9 has a high differentiation ability for GSE16011 samples.
