摘要 Objective: To discuss the ef ect of BRMS1 on the proliferation, migration and adhesion of mouse forestomach carcinoma(MFC). Methods: The constructed p CMV-myc-BRMS1 recombinant plasmid and blank plasmid were transfected into mouse forestomach carcinoma. MTT method was employed to measure the activity of gastric cancer cell; the scratch assay and Transwell assay to measure the migration and invasion of gastric cancer cell; the adhesion assay to measure the adhesion of gastric cancer cell; while the Western blot assay to measure the expression of The NF-毷B signal pathway, downstream matrix metalloproteinase(MMP-2), MMP-9 and osteopontin and E-cadherin in the gastric cancer cell. Besides, the transplanted animal model of gastric cancer in mice was constructed to measure the size of tumor xenograft. Results: Results of MTT assay showed that, compared with the empty vector control group, the activity of gastric cancer cell was not af ected in the BRMS1 transfection group. The improved expression of BRMS1 could inhibit the adhesion, migration and invasion of gastric cancer cell(P<0.01). Besides, compared with the empty vector control group, the phosphorylation of NF-毷B p65 and I毷Bα was reduced in the BRMS1 transfection group, with the decreased expression of MMP 2, MMP 9 and osteopontin and the increased expression of E-cadherin(P<0.01). Results of animal experiment also showed that the expression of BRMS1 did not af ect the transplanted tumor. Conclusions: The expression of BRMS1 can signii cantly inhibit the adhesion, migration, invasion and metastasis of MCF gastric cancer cell, which is related to The NF-毷B signal pathway.
