Figure Lengend Snippet: (A) mRNAsi (mRNA expression-based stemness index) comparison between high and low TMErisk groups. The high TMErisk group shows significantly lower mRNAsi (p = 0.026), indicating lower tumor cell stemness. (B) Immune cell infiltration analysis between high and low TMErisk groups. Significant differences are observed in various immune cell types, including naive B cells, memory B cells, plasma cells, CD8+ T cells, naive CD4+ T cells, and regulatory T cells (Tregs), with higher TMErisk scores associated with distinct immune cell infiltration patterns (*p < 0.05, **p < 0.01). (C) Enrichment analysis of gene function set in high-risk group based on GO database. (D) Enrichment analysis of gene function set in low-risk group based on GO database. (E) Enrichment analysis of gene function set in high-risk group based on KEGG database. (F) Enrichment analysis of gene function set in high-risk group based on KEGG database. (G) Correlation between TMErisk scores and immune phenotype scores (IPS) across different medulloblastoma subtypes. A significant negative correlation is observed in the G3 subtype (R = -0.31, p = 0.0081), indicating lower immune response in patients with higher TMErisk scores. (H) Correlation between TMErisk scores and tumor mutational burden (TMB) across different medulloblastoma subtypes. A significant positive correlation is observed in the G4 subtype (R = -0.44, p = 0.012), suggesting patients with higher TMErisk scores have lower TMB. (I) Drug sensitivity analysis showing significant differences in sensitivity to various cytotoxic and targeted therapy drugs between high and low TMErisk groups. High TMErisk scores are associated with reduced sensitivity to drugs like Camptothecin, Cytarabine, Navitoclax, Vorinostat, and Wee1 Inhibitor. ***: P<0.001, ns: Not Significant
