CXCL8, a chemokine ligand of the CXCR2 receptor, were implicated in tumorigenesis by enhancing endometrial adenocarcinoma cell (Sales et al. 2009) and melanoma cell (Richmond et al. 1986) proliferation and alveolar epithelial neoplasia (Wislez et al. 2006) and breast cancer (Bieche et al. 2007) development. This evidence concerns the gene CXCL8 and endometrium adenocarcinoma.
