These included genes encoding a litany of chemokines and chemokine receptors, such as Ccl2, -3, -4, -5, -7, -8, -11, and -12; Cxcl1, -2, -9, -10, -11, -13, and -16; Ccr1, -3, -5, -7, and -9; and Cxcr2, -3, and -6, indicating significant immune mobilization and recruitment to the irradiated tumor site. Here, CCL2 is linked to neoplasm.
