The activity of IL‐8 is mainly determined by the binding of IL‐8 to its receptors CXCR1 and CXCR2.9 In ovarian cancer, increased secretion of IL‐8 has been proved to promote tumour growth and upgrade metastasis.10 However, how IL‐8 enhances the metastasis and invasion of ovarian cancers cells remains unknown. Here, CXCR2 is linked to ovarian carcinoma.
