UNLABELLED Triple-negative breast cancers (TNBC) are characterized by a wide spectrum of genomic alterations, some of which might be caused by defects in DNA repair processes such as homologous recombination (HR). Despite this understanding, associating particular patterns of genomic instability with response to therapy has been challenging. Here, we show that allelic-imbalanced copy-number abe...
BACKGROUND Triple-negative breast cancer (TNBC) accounts for 15-20% of all breast tumors and these breast tumors are usually aggressive and highly metastatic. Unfortunately, treatment options for TNBCs are limited; we have identified a novel molecule, 2'-3'-dehydrosalannol (DHS) and in this study we investigated the anticancer effect of DHS against TNBC cells. MATERIALS AND METHODS TNBC (MDA-...
Purpose. Triple-negative breast cancer (TNBC) is defined by the loss of expression of ER, PR, and Her2neu expressions. The aim of this study was to examine the expression of the EGFR, CK5, and Ki-67 among triple-negative breast cancer cases and to correlate the expression of the basal markers with the clinicopathological prognostic parameters. Materials and Methods. Thirty-six female patients w...
BACKGROUND In this study, we used functional proteomics to determine the molecular characteristics of residual triple receptor-negative breast cancer (TNBC) patients after neoadjuvant systemic chemotherapy (NCT) and their relationship with patient outcomes in order to identify potential targets for therapy. PATIENTS AND METHODS Protein was extracted from 54 residual TNBCs, and 76 proteins rel...
Triple negative breast cancer (TNBC) is the most aggressive breast cancer subtype with the worst prognosis and no targeted treatments. TNBC patients are more likely to develop metastases and relapse than patients with other breast cancer subtypes. We aimed to identify TNBC-specific genes and genes associated with lymph node metastasis, one of the first signs of metastatic spread. A total of 33 ...
Triple negative breast cancer (TNBC) includes basal-like and claudin-low subtypes for which only chemotherapy and radiation therapy are currently available. The retinoblastoma (RB1) tumor suppressor is frequently lost in human TNBC. Knockdown of RB1 in luminal BC cells was shown to affect response to endocrine, radiation and several antineoplastic drugs. However, the effect of RB1 status on rad...
T riple negative breast cancer (TNBC) is associated with a poor prognosis compared to other types of breast cancer. The classification of 'triple negative' is not one homogenous tumor type, but rather is made up of multiple molecularly and biologically diverse tumor subtypes. At present, no approved targeted therapy exists and the standard remains cytotoxic chemotherapy. The identification of T...
The membrane bound glycoprotein mesothelin (MSLN) is a highly specific tumor marker, which is currently exploited as target for drugs. There are only limited data available on MSLN expression by human tumors. Therefore we determined overexpression of MSLN across different tumor types with Functional Genomic mRNA (FGM) profiling of a large cancer database. Results were compared with data in arti...
Triple negative breast cancer (TNBC) is a highly metastatic disease that currently lacks effective prevention and treatment strategies. The insulin-like growth factor 1 receptor (IGF1R) and focal adhesion kinase (FAK) signaling pathways function in numerous developmental processes, and alterations in both are linked with a number of common pathological diseases. Overexpression of IGF1R and FAK ...
Breast cancer is a big challenge for universal public health and has made as nuisance for every people who suffered from this disease. It is the second most common cause of cancer-related deaths in women worldwide. Triple-negative breast cancer (TNBC) is an advanced multi-drug resistance (MDR) breast cancer which affect majority of women worldwide Bakrania et al. [1]. TNBC is distinct by the la...
