Expression of COX-2, PG, some chemokines (such as IL-8, IL11), and nuclear and membrane-bound G protein-coupled receptors (like the F-prostanoid (FP) receptor) was upregulated in endometrial adenocarcinomas (Sales et al. 2009, 2010; Maldonado-Pérez et al. 2009). This evidence concerns the gene CXCL8 and endometrium adenocarcinoma.
