Figure 3. BCL2A1 was associated with GBM of the mesenchymal subtype. (A) TCGA, CGGA, Rembrandt and Gravendeel datasets were used to investigate the expression of BCL2A1 in GBM with different subtypes. (B) Accuracy of BCL2A1 in predicting the mesenchymal subtype as determined using ROC curves. (C, D) The Spearman correlation method was used to explore the relationship between BCL2A1 and mesenchymal-related markers in TCGA and CGGA. Abbreviations: AUC: area under the curve; ROC: receiver operating characteristic. *P < 0.05, **P < 0.01, ****P < 0.0001.
