In addition we compared their expression to known neuroblastoma promoting cytokines, chemokines, growth factors and their receptors and found GPR1 and CMKLR1 expression in the range of FPR1, IL6R and PDGFRA. While RARRES2 (chemerin) expression is lower than VEGFA, it is comparable to CCL2 and CCL5 expression (Supplementary Figure 2D and 2E). The gene discussed is CMKLR1; the disease is neuroblastoma.
