The expression of NEK7 is positively related to the infiltration of Treg cells (Fig. 3a), macrophages (Fig. 3b), monocytes (Fig. 3c), neutrophils (Fig. 3d), and M2 macrophages (Fig. 3e) in gastric cancer, even if it has no distinct correlation with infiltration of M1 macrophages (Fig. 3f). Here, NEK7 is linked to gastric cancer.
