BACKGROUND Triple-negative breast cancer (TNBC) is a highly diverse group that is associated with an aggressive phenotype. Its treatment has been challenging due to its heterogeneity and absence of well-defined molecular targets. Thus, there is an urgent need to identify novel agents with therapeutic application. NF-κB is over-expressed in many breast cancers; thus, inactivation of the NF-κB pa...

Celecoxib is a non-steroidal anti-inflammatory drug (NSAID) developed as a selective inhibitor of cyclooxygenase-2 (COX-2) for the treatment of rheumatoid arthritis disease. Recently some other mechanisms have been identified for anti cancer activity of these agents including induction of apoptosis, inhibition of tumor vascularization, stimulation of antitumor immune responses and inhibition of...

Within human carcinomas, there is often an infiltration of lymphocytes and other cells of the immune system. A variety of cytokines are produced by such cells that could have a paracrine influence on the growth of tumor epithelium. The effect of one of these cytokines, interleukin-4 (IL-4), on human breast and colon cancer cell lines was therefore examined. IL-4 inhibited the growth of human co...

The aim of this work was to understand whether the nature of breast cancer cells could modify the nature of the dialog of mesenchymal stem cells (MSCs) with cancer cells. By treating MSCs with the conditioned medium of metastatic Estrogen-receptor (ER)-negative MDA-MB-231, or non-metastatic ER-positive MCF-7 breast cancer cells, we observed that a number of chemokines were produced at higher le...

UNLABELLED The epidermal growth factor receptor (EGFR) is an attractive target for the design of radiotherapeutic agents for breast cancer because it is present on almost all estrogen receptor-negative, hormone-resistant tumors with a poor prognosis. In this study, we describe the antitumor effects and normal tissue toxicity of the novel Auger electron-emitting radiopharmaceutical (111)In-label...

Radioimmunotherapy (RIT) is a systemic therapy currently used in the treatment of patients with lymphoma. RIT complexes consist targeting molecule, commonly an antibody, radionuclide chelates and linker which can be nanoparticle platform. Nanoparticles facilitate attachment multiple radionuclides groups to single complex. Here target affinity, duration association inhibition colony formation Ce...

Cancer stem cells (CSCs) are a subset of cancer cells in tumors or established cancer cell lines that can initiate and sustain the growth of tumors in vivo. Cancer stem cells can be enriched in serum-free, suspended cultures that allow the formation of tumorspheres over several days to weeks. Brefeldin A (BFA) is a mycotoxin that induces endoplasmic reticulum (ER) stress in eukaryotic cells. We...
