乳腺癌转移抑制基因1抑制乳腺癌转移的作用机理研究进展

目的综述乳腺癌转移抑制基因1（BRMS1）在抑制乳腺癌转移中的作用机理研究进展。方法采用文献回顾的方法，对目前国内、外有关BRMS1在乳腺癌中的研究状况加以分析与综述。结果BRMS1与其他肿瘤转移抑制基因一样，主要抑制肿瘤的转移，并不影响肿瘤的生长，在乳腺癌中主要通过调节细胞间的信号转导及其他转移抑制基因的表达而抑制乳腺癌的转移。结论对BRMS1基因的深入研究有助于进一步深化对乳腺癌转移的认识，为肿瘤转移的分子诊断和基因治疗提供新的思路。

Suppressing Function of Breast Cancer Metastasis Suppressor 1 in Breast Cancer Metastasis

Objective To review the recent studies on the suppressing function of breast cancer metastasis suppressor 1 (BRMS1) in breast cancer metastasis. Methods The recent literatures on the mechanisms of BRMS1 in the breast cancer that were published in and abroad were reviewed and summarized. Results BRMS1, similar to the other anti-metastasis genes, only suppresses the metastasis of breast cancer cells but has nothing to do with the growth of tumor. BRMS1 could suppress metastasis of tumor cells by reestablishing both the homospecific and the heterospecific gap junctional intercellular comminications (GJIC) and by altering the expressions of relevant metastasis genes in the breast cancer. Conclusion Further studies on BRMS1 may be helpful to understand the metastasis of breast cancer, which may provide a new way for the diagnosis and treatment of breast cancer.
