CD4 and neoplasm: As shown in Figure 8A, CCDC134 expression was correlated with tumor purity (r = 0.023, P = 4.68E −01), B cells (R = 0.125, P = 9.54E −05), CD8+ T cells (r =0.108, P = 7.38E −04), CD4+ T cells (r = 0.101, 1.66E-03), macrophages (r = 0.101, P = 1.54E−03), neutrophils (r = 0.189, P = 4.62E−09) and dendritic cells (r = 0.165, P = 2.92E−07) were correlated.
