NCOA3 as a critical oncogene in Thyroid cancer via modulating major signaling pathways
Abstract Nuclear Receptor Coactivator (NCOA3) enhances transcriptional activation of nuclear hormone receptors. This study was designed to explore the role of NCOA3 in thyroid cancer. Our data demonstrated that protein expression of NCOA3 was significantly upregulated in thyroid cancer tissues. NCOA3 knockdown inhibited cell proliferation and invasion, and induced cell cycle arrest and apoptosis in thyroid cancer. Conversely, ectopic expression of NCOA3 promoted cell proliferation and invasiveness in thyroid cancer. Mechanically, NCOA3 promotes thyroid cancer cell survival and invasiveness through modulating PI3K/AKT, MAPK and Wnt/β-catenin pathways. Collectively, these findings suggest that NCOA3 is critical in the initiation and development of thyroid cancer, and maybe a possible marker for prognostic and therapeutic.
