They further showed that CXCL1 and CXCR2 expression was elevated in the cancer tissue and that PGF2α‐FP receptors signalling promotes CXCL1 expression on endometrial adenocarcinoma cells and attracts CXCR2‐expressing neutrophils (Wallace et al., 2009). This evidence concerns the gene CXCR2 and endometrium adenocarcinoma.
