CD8A and glioblastoma: There was a negative correlation between the infiltration level of CD8+ T cells and FUBP1 expression in GBM (p = 4.95e−02 with XCELL and p = 1.19e−02 with MCPCOUNTER), HNSC-HPV- (p = 6.43e-03 with TIMER and p = 4.72e-07 with EPIC), and UCEC (p = 4.62e−02 with XCELL and p = 7.54e-03 with CIBERSORT), but either a negative or positive correlation was observed in LGG with different algorithms (Figure 6).
