IL-6 promotes endometrial cancer cells invasion and migration through signal transducers and activators of transcription 3 signaling pathway.

In this study, we aimed to investigate the role of IL-6/Stat3 signaling pathway in human endometrial cancer cells invasion and migration. We demonstrated that Stat3 is activated in endometrial cancer cell lines. To investigate the role of Stat3 in endometrial cancer invasive capacity, we used Stat3 inhibitor Stattic and found that Stattic significantly inhibited the migration and invasion of endometrial cancer cells elevated by IL-6. Furthermore, we showed that Stat3 inhibitor significantly decreased the expression of MMP2 enhanced by IL-6, indicating that IL-6 promoted endometrial cancer invasion and migration by Stat3-induced MMP2 upregulation. Taken together, our findings indicate that targeting IL-6/Stat3 pathway might be a potentially effective therapeutic strategy for treating endometrial cancer.
