A miR-20a/MAPK1/c-Myc regulatory feedback loop regulates breast carcinogenesis and chemoresistance.

Chemoresistance often leads to the failure of breast cancer treatment. MicroRNAs (miRNAs) play an important role in the progression and chemoresistance of cancer. However, because of the complexity of the mechanisms of chemoresistance and the specificity of miRNA regulation in different cell types, the function of miR-20a in breast cancer chemoresistance is still unclear.

miR-145 suppresses breast cancer cell migration by targeting FSCN-1 and inhibiting epithelial-mesenchymal transition.

MicroRNAs (miRNAs), small non-coding RNAs, regulate fundamental cellular and developmental processes such as cell growth, apoptosis, migration, and invasion. In our present study, we investigated the inhibitory role of miR-145 on breast cancer cell migration as well as its underlying mechanism. Wound healing assay and transwell migration assay showed that ectopic expression of miR-145 significantly inhibited breast cancer cell migration.

Knockdown of miR-182 promotes apoptosis via regulating RIP1 deubiquitination in TNF-α-treated triple-negative breast cancer cells.

Overexpression of microRNA-182 (miR-182) is found in multiple cancers, but the association of miR-182 expression with the sensitivity of triple-negative breast cancer (TNBC) cells to tumor necrosis factor-alpha (TNF-α) remains unknown. In this study, up-regulation of miR-182 was validated in TNBC patients and cell lines. Knockdown of miR-182 was observed to hinder the proliferation of BT-549 cells.

However, the relationship between p53 and Fascin is not understood.

The role of miR-125b-mitochondria-caspase-3 pathway in doxorubicin resistance and therapy in human breast cancer.

MicroRNAs (miRNAs) are a class of naturally occurring, small, non-coding RNAs which play important roles in diverse biological processes and are acting as key regulators of tumorigenesis and chemotherapy resistance. In this study, a downregulation of miR-125b was observed in breast cancer cell lines, suggesting miR-125b is a tumor suppressor in breast cancer. Moreover, the miR-125b levels were significantly decreased in doxorubicin-resistant MCF-7 (MCF-7/DR) cells compared with MCF-7 cells.

MicroRNAs-mediated cell fate in triple negative breast cancers.

MicroRNAs (miRNAs) are small non-coding RNAs that function as major modulators of posttranscriptional protein-coding gene expression in diverse biological processes including cell survival, cell cycle arrest, senescence, autophagy, and differentiation. The control of miRNAs plays an important role in cancer initiation and metastasis. Triple negative breast cancer (TNBC) is a distinct breast cancer subtype, which is defined by the absence of estrogen receptor (ER), progesterone receptor (PR) and epidermal growth factor receptor 2 (HER2/neu).
