Previous studies suggested that bisphosphonate zoledronic acid exerts an anti-tumor effect by interacting with the microenvironment. In this study, we aimed to elucidate the mechanism behind the anti-breast cancer effect of zoledronic acid.Here we showed that zoledronic acid did not influence in vitro human breast cancer cell survival, but did affect human stromal cell survival. Breast cancer c...

two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including mcf-7 (breast cancer cell), hepg2 (liver hepatocellular cells), a549 (adenocarcinomic human alveolar basal epithel...

We investigate the anti-cancer stem cell (CSC) properties of two copper(II) complexes containing 4,7-diphenyl-1,10-phenanthroline and a S, N, X-Schiff base ligand, where X=O (1) or S (2). Complex 1 was previously reported by us, is first metal complex to induce cytotoxic immunogenic death breast CSCs. 2 structural analogue 1, phenolate moiety (within Schiff ligand) replaced thiophenolate group....

background: chemokine receptors have been shown to play an important role in the development and metastatic spread of various malignancies. in this study, the gene expression profile of some key chemokine receptors involved in metastasis has been investigated in esophageal and breast cancer cell lines.   methods: in a descriptive study, gene expression profile of ccr1, ccr6, ccr7, ccr9, cxcr1, ...

Breast cancer is the most common cancer type among women all over the world. Chemotherapy is the use of anticancer medicines for treating cancer but it has many side effects and cells may become resistant to these chemical medicines. Therefore, finding new compounds of natural origin could be a promising solution to this problem. The aim of the current study was to evaluate anticancer activity ...

stem cell based treatments are being increasingly explored for their possible potential to treat various cancers. mesenchymal stem cells believed to possess anti-tumor potential and are preferred for their properties like immune privileged nature, ability to migrate to the site of tumor and capability for multilineage differentiation. this tumor tropism property of mscs could be utilized to del...

Disruption of circadian rhythm is a major cause of breast cancer in humans. Cryptochrome (CRY), a circadian transcription factor, is a risk factor for initiation of breast cancer, and it is differentially expressed between normal and breast cancer tissues. Here, we evaluated the anti-proliferative and pro-apoptotic activity of KS15, a recently discovered small-molecule inhibitor of CRY, in huma...
