After determining the tumor purity, we found that for PAAD, high expression of USP10 correlated significantly and positively with the infiltration levels of CD8+ T cells (r = 0.387, P = 1.67e-07), B cells (r = 0.355, P = 1.94e-06), macrophages (r = 0.318, P = 2.31e-05), neutrophils (r = 0.383, P = 2.32e-07), and dendritic cells (r = 0.417, P = 1.37e-08) (Figure 8A). This evidence concerns the gene CD8A and neoplasm.
