CCL4 chemokine (also known as macrophage inflammatory protein, MIP-1β), implicated in the recruitment of peripheral monocytes to the tumor site, was upregulated in progressive patients as compared with ‘Stable+Elite’ patients (log(fold change [FC]) = +1.67; adjusted P = 0.011, Fig. 4c). The gene discussed is CCL4; the disease is neoplasm.
