NCOA4 and neoplasm: To intensely explore the possible role of NCOA4 in the infiltration of various immune cells in ccRCC, we used the GEPIA and TIMER databases to execute the relationships between NCOA4 and several immune marker sets, which were widely accepted as corresponding symbols of different immunocytes, such as CD8+ T cells, T cells (general), B cells, M1/M2 macrophages, tumor-associated macrophages, neutrophils, monocytes, NK, and DCs in ccRCC (Table 2).
