Studies have shown that TRIM protein can regulate transcription factor activity and is associated with many cancers. However, the role of TRIM11 in gastric cancer remains unclear.Methods: TRIM11 protein levels were examined in 36 cases of GC tissues and 4 gastric cancer cell lines. TRIM11 overexpression and knockdown cells were constructed in MGC-803, HGC-27 and SGC-7901, respectively. The biological roles and mechanisms of TRIM11 were examined using CCK8, colony formation, transwell migration assay, invasion assay, Western blotting, Immunohistochemistry and in vivo nude mice experiments.Results: We found that TRIM11 was upregulated in gastric cancer tissues and gastric cancer cell lines. Functionally, TRIM11 overexpression increased growth rate, colony formation, invasion and migration ability, EMT and β-catenin protein level and its downstream proteins such as CyclinD1 and C-myc, while TRIM11 knockdown shows the opposite effects.Conclusion: In summary, our data show that TRIM11 is overexpressed in GC. TRIM11 promotes proliferation, migration, invasion and EMT of gastric cancer by activating β-catenin signaling.Keywords: TRIM11, gastric cancer, proliferation, migration, invasion, EMT
