Although RNF169 expression had no significant correlation with tumour purity (r = −.046, p = 5.45 e−01) (Figure 4J), we observed a significant correlation between RNF169 expression and the infiltration levels of B cells (r = .436, p = 2.51e−09) (Figure 4K), CD8+ T cells (r = .685, p = 5.56 e−25) (Figure 4L), macrophages (r = .566, p = 6.91 e−16) (Figure 4N), neutrophils (r = .497, p = 4.95 e−12) (Figure 4O) and dendritic cells (DCs) (r = .522, p = 2.50 e−13) (Figure 4P) in PAAD, but not CD4+ T cells (r = −.096, p = 2.17 e−01) (Figure 4M). The gene discussed is CD4; the disease is neoplasm.
