CCR2 and monocytic leukemia: We then performed <i>CCR2</i> perturbation assays in human monocytic leukemia cell line (THP-1) and immortalized bone marrow-derived macrophage (IBMDM) cells with artemin (<i>ARTN</i>) mRNA readouts and examined proteomic correlations for <i>ARTN</i> using the Olink inflammatory panel.<h4>Results</h4>Eight immune phenotypes showed FDR-significant causal associations with malignancy, seven of which remained independent in MVMR.
