PRKCE and neoplasm: Interestingly, the expression of PRKCE was negatively associated with tumor-infiltration immune effector cells from both innate and adaptive immune systems, including Treg cells (R = -0.330, p < 0.001), aDC (R = -0.117, p = 0.006), cytotoxic cells (R = -0.261, p < 0.001), CD8 T cells (R = -0.132, p = 0.002) (Figures 6B–E) and positively associated with eosinophils, neutrophils, mast cells, and T helper cells (Figures 6F–I).
