CCL22 and invasive breast carcinoma: Using the ONCOMINE database (TCGA breast invasive carcinoma dataset), out of all known CC chemokines 7 CC chemokines’ [(CCL5 (FC = 1.6, p = 8.6e−05), CCL7 (FC = 4.5, p = 1.43e−14), CCL11 (FC = 5.5, p = 1.29e−31), CCL17 (FC = 2.0, p = 3.32e−09), CCL20 (FC = 2.2, p = 2.07e−06), CCL22 (FC = 1.44, p = 1.5e−04) and CCL25 (FC = 1.6, p = 1.33e−08)] mRNA were significantly (fold change ≥1.4 and p-value ≤ 0.04) elevated in BrCa compared to normal tissues (Table 1).
