Among these chemokines, high expression of CCL2, CCL3, CCL7, CCL20, CXCL1, and CXCL10, is correlated with poorer overall survival of cancer patients than patients with low expression (p < 0.05) (Gyorffy et al., 2013, 2014; Menyhart et al., 2018; Nagy et al., 2018; Figure 2C). The gene discussed is CCL2; the disease is cancer.
