Our results indicated that the expression of ORC1, ORC2, ORC3, ORC4, ORC5, and ORC6 was different in the seven common types of tumor‐infiltrating immune cells, such as B cells, CD4 T cells, CD8 T cells, NK cells, macrophages, endothelial cells, and cancer‐associated fibroblasts (Figure 8A). Here, ORC6 is linked to cancer.
