Tripartite motif (TRIM)-containing protein 14 (TRIM14) is implicated in many malignancies. Presently, we studied whether TRIM14 played a role in human papillary thyroid carcinoma (PTC). Herein, TRIM14 was up-regulated in tumor tissues when compared with normal thyroid samples. Among PTC patients, enhanced TRIM14 predicted short recurrence free survival (RFS) time. Then, we found that knockdown of TRIM14 in human PTC K1 cells inhibited cell proliferation, induced cell apoptosis and prevented the tumorigenicity in nude mice. On the contrary, TRIM14 overexpression in human PTC TPC1 cells promoted cell proliferation while inhibited cell apoptosis. TRIM14 exerted its oncogenic activities via promoting the activation of signal transducer and activator of transcription 3 (STAT3). Further, TRIM14 interacted with the suppressor of cytokine-signaling-1 (SOCS1), a negative regulator of STAT3 activation, and knockdown of TRIM14 inhibited SOCS1 ubiquitination. In conclusion, TRIM14 may be a prognostic factor and oncogene in PTC, and may be a potential target for PTC intervention. •TRIM14 was up-regulated in papillary thyroid carcinoma.•Enhanced TRIM14 predicted short recurrence free survival time.•Knockdown of TRIM14 inhibited cell proliferation and induced cell apoptosis.•Knockdown of TRIM14 inhibited the ubiquitination of SOCS1.
