摘要:
Interleukin-8 (IL-8), as an inflammatory chemokine, has been previously shown to contribute to tumorigenesis in several malignancies including the ovarian cancer. However, little is known about how IL-8 promotes the metastasis and invasion of ovarian cancers cells. In this study, we found that IL-8 and its receptors CXCR1 and CXCR2 were up-regulated in advanced ovarian serous cancer tissues. Furthermore, the level of IL-8 and its receptors CXCR1 and CXCR2 expression were associated with ovarian cancer stage, grade and lymph node metastasis. In vitro, IL-8 promoted ovarian cancer cell migration, initiated the epithelial-mesenchymal transition (EMT) program and activated Wnt/beta-catenin signalling. However, when treated with Reparixin (inhibitor of both IL-8 receptors CXCR1 and CXCR2), effect of both endogenous and exogenous IL-8 was reversed. Together, our results indicated that IL-8 triggered ovarian cancer cells migration partly through Wnt/beta-catenin pathway mediated EMT, and IL-8 may be an important molecule in the invasion and metastasis of ovarian cancer.
