Metastases are the main cause of cancer-related mortality in breast cancer.Although significant progress has been made in the field of tumor metastasis,the exact molecular mechanisms involved in tumor metastasis are still unclear.Here,we report that ATOH8-V1,a novel isoform of ATOH8,is highly expressed in breast cancer and is a negative prognostic indicator of survival for patients.Forced expression of ATOH8-V1 dramatically enhances,while silencing of ATOH8-V1 decreases the metastasis of breast cancer cell lines.Moreover,ATOH8-V1 directly binds to the RhoC promoter and stimulates the expression of RhoC,which in turn enhances the metastasis of breast cancer.Altogether,our data demonstrate that ATOH8-V1 is a novel pro-metastatic factor that enhances cancer metastasis,suggesting that AT0H8-V1 is a potential therapeutic target for treatment of metastatic cancers. 展开更多
