Interleukin-23 Facilitates Thyroid Cancer Cell Migration and Invasion by Inhibiting SOCS4 Expression via MicroRNA-25.

Interleukin-23 (IL-23) is a conventional proinflammatory cytokine that plays a role in tumor progression by inducing inflammation in the tumor microenvironment. However, the role of IL-23 in thyroid cancer migration and invasion remains unclear. In the present study, we observed that the treatment with IL-23, induced migration and invasion in human thyroid cancer cells. Additional data demonstrate that SOCS4 negatively regulates IL-23-mediated migration and invasion. On investigating the mechanisms involved in IL-23 mediated migration and invasion, we observed that miR-25 promotes the migration and invasion of thyroid cancer cells by directly binding to the 3'-UTR of SOCS4 that leads to the inhibition of SOCS4. In addition, we also demonstrated that IL-23 increases miR-25 expression levels, and overexpressed miR-25 is involved in IL-23-associated SOCS4 inhibition and cell migration and invasion. Together, our data suggest that IL-23 induces migration and invasion in thyroid cancer cells by mediating the miR-25/SOCS4 signaling pathway.
