As shown in Figures 6B–J, RAD21, BOP1, POLR2E, and PRKDC were mainly expressed in tumor cells, RIPK2 was mainly expressed in monocytes, MAP2K2 was mainly expressed in tumor cells and macrophages, NBN was mainly expressed in macrophages and monocytes, and GPX4 was mainly expressed in tumor cells and T cells. This evidence concerns the gene MAP2K2 and neoplasm.
