Metabolites linked to changes in choline kinase-α (CK-α) expression and drug resistance, which contribute to survival and autophagy mechanisms, are attractive targets for breast cancer therapies. We previously reported that autophagy played a causative role in driving tamoxifen (TAM) resistance of breast cancer cells (BCCs) and was also promoted by CK-α knockdown, resulting in the survival of T...
BACKGROUND As a kind of versatility of cytokines, overexpression of macrophage migration inhibitory factor (MIF) and vascular endothelial growth factor-C (VEGF-C) have been reported in a wide variety of tumors. However, the correlation and mechanism between MIF and VEGF-C are still not clear. As an important signal transduction system, MAPK signaling pathways participate in a variety of biologi...
To search for new targets of anticancer therapies using phytoestrogens we performed comparative metabolic profiling of the breast cancer cell line MCF-7 and the non-tumorigenic breast cell line MCF-12A. Application of gas chromatography-mass spectrometry (GC-MS) revealed significant differences in the metabolic levels after exposure with 17ß-estradiol, genistein or a composition of phytoestroge...
Purpose: It was aimed to evaluate the effect of hydrogen peroxide (H2O2), mitochondria isolated from human breast cancer cells (MCF-7) and mesenchymal stem (IMSCs) on MCF-7 cell proliferation in this study.
 Materials Methods: Mitochondria IMSCs were according protocols specified kit protein amount measured by bicinchoninic acid method (BCA). H2O2 doses (0-1000 µM), obtained transferred vi...
Breast cancer stem cells (BCSCs) are believed to be responsible for tumor chemoresistance, recurrence, and metastasis formation. Salinomycin (SAL), a carboxylic polyether ionophore, has been reported to act as a selective breast CSC inhibitor. However, the molecular mechanisms underlying SAL-induced cytotoxicity on BCSCs remain unclear. The Hedgehog (Hh) signaling pathway plays an important rol...
Based on our studies demonstrating first time evidence that the cyclooxygenase-2 (Cox-2) enzyme is abundant within invasive human breast tumors, we developed a clonally derived human breast tumor cell clone designated as MCF-7/Cox-2 Clone 10 by transfection of human Cox-2 cDNA into slow growing, Cox-2 null, non-metastatic MCF-7 human breast tumor cells. The present studies evaluated the biologi...
