GE of AT/RT, MB and normal brain tissue. a Hierarchical clustering of GE profiling showed 1,002 genes significantly differentially expressed with ≥2 or ≤−2 fold-change, and p-value <0.05. b Analysis of GE data showed that NCAM1 was significantly downregulated in AT/RT when compared to MB and normal brain tissues (**P < 0.01, ****P < 0.0001, one-way ANOVA). c Validation of GE data by qRT-PCR. NCAM1 expression level was significantly lower in AT/RT when compared to MB and normal brain tissues (*P < 0.05, **P < 0.01, one-way ANOVA)
