Transcriptional analysis highlighted high levels of genes that promote the infiltration by tumor-associated macrophages (TAMs) and monocytes (Ccl2, Csf2, Ccl20, Ccl7), B-cells (Cd19, Il5), granulocytes (Csf3, Csf3r, Csf2, Nos2), and, especially, tumor-associated neutrophils (TANs) (Cxcl5, Cxcl3, Cxcl2, Cxcl1). The gene discussed is NOS2; the disease is neoplasm.
