NUCB2 and glioblastoma: Analysis using TIMER 2.0 revealed significant positive correlations between NUCB2 expression and the infiltration levels of macrophages (Spearman's ρ = 0.214, p = 1.18e‐02; Figure 4A) as well as CD8+ T cells (Spearman's ρ = 0.264, p = 1.83e‐03; Figure 4B) within GBM tissues.
