Cytokine profiling of the purified Gr1− populations (Fig. 7E) tells us that both, IL-6 and TNFα, which are related to tumor associated macrophages, were enriched in only oleate but not in the control or stearate group, implying a strong relationship between oleate metabolism and the formation of tumor associated macrophages in cytokine level. The gene discussed is IL6; the disease is neoplasm.
