Figure 3. Effect of Mutated versus Wild-Type ATRX on Immune Marker Expression.
A. GBM samples were tested for immune marker expression by IHC and compared based on ATRX mutant status. CD3 was significantly higher in ATRX mutated tumors (p=0.0306) shown as an odds ratio of greater than 1. B. TCGA analysis of GBM samples revealed that CD3 (p=0.0043), CD8 (p=0.0011), CD70 (p=0.0060), CD163 (p=0.0135), CD274 (gene for PD-L1) (p=0.0229), and PDCD1 (gene for PD-1) (p=0.0101) were lower in ATRX mutated tumors.
Circled odds ratio or mean ratio point estimates differ significantly from one at α=0.05.
