Although the incidence of nasopharyngeal carcinoma (NPC) is relatively low, the mortality is very high and the patients have a poor prognosis. Thus, it is urgent to find a novel biomarker and a new therapeutic strategy. Suppressor of cytokine signaling-2 (SOCS2) was reported to be associated with various malignancies. However, the exact role of SOCS2 in NPC still remains largely unsure. In the present study, we showed that the expression of SOCS2 was significantly upregulated in NPC patients and cells. And the high expression of SOCS2 predicted a worse outcome in NPC patients. Moreover, the in vivo experiments indicated that knockout of SOCS2 inhibits the proliferation, migration, and invasion of NPC cells. Besides, we found a positive relationship between SOCS2 and EphA1 in NPC tissues. The rescue experiments indicated that SOCS2 affected the malignancy of NPC cells by regulating the expression of EphA1. Altogether, our data uncovered the ontogenetic role of SOCS2 dysregulation during the tumorigenesis of NPC. SOCS2 might serve as a biomarker during the diagnosis and treatment of NPC. And targeting SOCS2 might provide a novel treatment strategy for NPC patients.
