Our results showed that the expression of MAPK3 was significantly positively correlated with the infiltration levels of macrophages (P=2.78 × 10-4), B cells (P=7.43 × 10-5), mast cell activation (P=7.43 × 10-5), and cancer-associated fibroblasts (P=8.39 × 10-5) (Figure10A-E). The gene discussed is MAPK3; the disease is cancer.
