Triple negative breast cancer (TNBC) is one of the breast cancer molecular subtypes that characterized with lack in expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) [1]. As targeted therapy is not available and current treatments for TNBC is not efficient, thus better diagnostic and therapeutic approaches like molecular targets are essential. [2]. MicroRNAs are a group of non-coding RNAs with regulatory effects in biological process [3]. They have potential as candidate diagnostic biomarkers and therapeutic targets in cancers [4]. In this bioinformatics study, we aimed to identify the differential expression microRNAs in TNBC samples compared to non-TNBC samples.
