The tripartite motif ( TRIM ) family comprises more than 70 members involved in the regulation of many cellular pathways. TRIM 32 acts as an E3 ubiquitin ligase and has been reported to participate in many human cancers. Here, we aimed to investigate the role of TRIM 32 in gastric cancer ( GC ) and the clinical implications. High expression of TRIM 32 was observed in GC tissues and cell lines, and was significantly associated with poor prognosis. Knockdown TRIM 32 expression remarkably suppressed the proliferation, migration, and invasion of GC cells in vitro and tumour growth in vivo, whereas overexpression of TRIM 32 yielded the opposite results. Western blotting and quantitative reverse‐transcription PCR ( qRT ‐ PCR ) analyses revealed that up‐regulation of TRIM 32 significantly enhanced expression of β‐catenin protein and of its downstream targets TCF 1, cyclin D1, Axin2 and MMP 7 mRNA s. Moreover, we found that the mechanism behind the TRIM 32‐promoted GC progression was related to the β‐catenin signalling pathway. Collectively, these data suggest that TRIM 32 promotes GC cell proliferation, migration, and invasion by activating the β‐catenin signalling pathway.
