CXCL1 and neoplasm: Conversely, the pro‐tumor phenotype (N2) of TANs is characterized by high levels of CCL2, CCL3, CCL4, CCL8, CCL12, CCL17, CXCL1, CXCL2, CXCL8, and CXCL16 chemokines.[36] To confirm the phenotypic effects on HL‐60 cells cultured in the conditioned medium derived from shNKX2‐1‐transfected H1975 and HCC827 cells, we conducted qRT‐PCR analysis.
