Objective: To investigate the expression of breast cancer metastasis suppressor 1 (BRMS1) mRNA in supraglottic cancer and to evaluate its clinical significance.
Method: The expression of BRMS1 mRNA was examined by using RT-PCR method which take beta-actin mRNA as reference template in 66 cases of supraglottic cancer tissues and their adjacent normal mucosa tissues (ANT).
Result: The expression of BRMS1 mRNA in the tissues of supraglottic cancer is lower significantly than that in the tissues of ANT ( P<0.05). There is correlation between BRMS1 mRNA expression and the clinical stage, differentiation and cervical lymph node metastasis in the laryngeal supraglottic cancers (P<0.05). There is no correlation between BRMS1 mRNA expression and sex and age.
Conclusion: Expression of BRMS1 mRNA in supraglottic cancer is lower than that in adjacent normal mucosa. The decrease of BRMS1 mRNA expression may be related to clinical stage and low differentiation and lymph node metastasis of supraglottic laryngeal cancer.

The metastatic suppressor BRMS1 interacts with critical steps of the metastatic cascade in many cancer entities. As gliomas rarely metastasize, BRMS1 has mainly been neglected in glioma research. However, its interaction partners, such as NFκB, VEGF, or MMPs, are old acquaintances in neurooncology.

The functions of long noncoding RNAs (lncRNAs) have been widely investigated in human cancers, including gastric cancer (GC). The purpose of this study was to elucidate the role of lncRNA HCG11 in GC. In this study, mRNA and protein expressions were detected by quantitative real-time polymerase chain reaction assays (RT-qPCR) and Western blot analysis.

In recent years, there has been progress in the treatment of breast cancer; however, the prognosis is still poor due to recurrence and metastasis following conventional treatment. The anti-tumor peptide SA12 has been demonstrated to inhibit proliferation and arrest the cell cycle in MDA-MB-231 and MCF-7 breast cancer cells. In the present study, whether SA12 was able to inhibit the metastasis of breast cancer cells was investigated.
