Lines of evidence have demonstrated that the oncogenic miRNAs are pivotal to the progression of breast cancer. In this study, we investigated the biological traits of microRNA-429 (miR-429) in triple-negative breast cancer (TNBC) and the underlying molecular mechanism. We found that miR-429 was notably overexpressed in TNBC, and promoted TNBC cell proliferation, migration, and invasion by degrading the tumor suppressor DLC1. In conclusion, our findings reveal the mechanism of tumorigenic miR-429 in TNBC, which paves the way for target therapies translation in clinical settings.
