Abstract
Abstract Triple negative breast cancer (TNBC) is the most aggressive type of all breast cancer subtypes. Although various studies have been performed to identify prognostic and therapeutic targets for TNBC, the TNBC specific biomarkers have not yet been elucidated. Herein, we identified dysregulated miRNAs in TNBC via analysis of miRNA microarray in breast cancer tissues and found the oncogenic RNA (miR-374a-5p) and tumor suppressive miRNAs (miR-320c, miR-371b-5p). These miRNAs were closely related to overall survival of TNBC patients and status and involved in TNBC progression or drug responsiveness. Collectively, these results suggest that dysregulated miRNAs might serve as potential prognostic marker or therapeutic target for TNBC.
