MYD88 and glioblastoma: We also found that MYD88 expression was the highest in the Mesenchymal subtype (Supplementary Figure 4C), and it associated with many kinds of cell death pathways, and negatively correlated to PD1 expression (Supplementary Figures 4D, 4E) Finally, the correlation between IPS score and MYD88 expression in GBM patients was established (Supplementary Figures 4F).
