UNLABELLED Triple-negative breast cancer (TNBC) is associated with poor survival. Chemotherapy is the only standard treatment for TNBC. The prevalence of BRCA1 inactivation in TNBC has rationalized clinical trials of poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors. Similarly, the overexpression of epidermal growth factor receptor (EGFR) rationalized anti-EGFR therapies in this d...
mir-101-3p has been reported to be a tumor suppressor and a promising therapeutic target in cancer. Recently, AMPK dysfunction has been highlighted in cancers, including breast cancer. The aim of this study is to investigate the biological roles of mir-101-3p and AMPK in breast cancer. Our research demonstrated that AMPK was up-regulated in breast cancer tissues and cell lines, especially in tr...
BACKGROUND This study was performed to investigate the effect of microRNA-203 (miR-203) on cell proliferation and migration in triple-negative breast cancer (TNBC). METHODS Real-time PCR was performed to detect the expression of miR-203 in TNBC cell lines. miR-203 precursor and control microRNA (miRNA) were transfected into triple-negative breast cancer (TNBC) cell lines and the effects of mi...
Recently, BRCA1 germline mutations were found in a high proportion (14-34%) of patients with triple-negative breast cancer (TNBC). BRCA2 was either not analyzed or showed much lower mutation frequencies. Therefore, we screened a group of TNBC patients (n = 30) of white European descent for mutations in BRCA2 as well as in BRCA1. Cases were unselected for age of disease-onset (median age at brea...
Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer for which there is no effective treatment. Previously, we and others demonstrated that CXCR4 surface expression is an independent prognostic factor for disease relapse and survival in breast cancer. In this study, we investigated the effects of CXCR4 gene silencing on cisplatin chemosensitivity in human triple-negative ...
Triple-negative breast cancer (TNBC) is usually the most malignant and aggressive mammary epithelial tumor characterized by lack of expression for estrogen receptors progesterone receptors, absence epidermal growth factor receptor (HER)2 amplification. Corresponding to 15–20% all cancers well-known its poor clinical outcome, this negative deprives TNBC from targeted therapy makes management the...
Triple negative breast cancer (TNBC) is a highly heterogeneous tumor. There is increasing evidence of the role of tumor lymphocytic immune infiltrates in this subtype of breast cancer. Robust levels of tumor infiltrating lymphocytes (TILs) have been associated with improved disease-free and overall survival rates in TNBC patients with and without any treatment. Recent efforts have been made to ...
BACKGROUND Triple-negative breast cancer (TNBC) lacking expression of steroid receptors and human epidermal growth factor receptor 2, having chemotherapy as the only therapeutic option, is characterised by early relapses and poor outcome. We investigated intratumoural (i.t.) levels of the pro-angiogenic cytokine vascular endothelial growth factor (VEGF) and survival in patients with TNBC compar...
Parity associated breast cancer (PABC) often diagnosed within the 2-5 years after a full term pregnancy. PABC is usually present with more advanced, poorly differentiated, high-grade cancers that show shorter time to progression and often of the triple negative breast cancer (TNBC) subtype. Data from around the world show that pregnancy-associated TNBC is independently associated with poor surv...
PURPOSE Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype that is associated with poor clinical outcome. There is a vital need for effective targeted therapeutics for TNBC patients, yet treatment strategies are challenged by the significant intertumoral heterogeneity within the TNBC subtype and its surrounding microenvironment. Receptor tyrosine kinases (RTK) are highl...
