چکیده

Our previous studies revealed that daintain/AIF-1 promoted the proliferation and migration of breast cancer cells. In the present study, we investigated the effect of daintain/AIF-1 on the cisplatin resistance of breast cancer cells. The results indicated that daintain/AIF-1 reinforced the resistance of breast cancer cells to cisplatin by inhibition of cell apoptosis and reduction of intracellular cisplatin accumulation.

Expression, purification, and characterization of functional recombinant human daintain/AIF-1 in Escherichia coli.

Daintain/AIF-1 was identified from injured rat carotid arteries and porcine intestine in the mid 1990s. It is involved in autoimmune disorders, chronic rejection of allografts, gliomas, and breast cancer. Since it is convenient and economical to obtain such a peptide biologically, in this study, we describe the expression, purification, and characterization of recombinant human daintain/AIF-1 (...

Sambucus Nigra Synergizes Cisplatin to Improve Apoptosis and Metabolic Disorders, and Reduce Drug Resistance in Two Human Breast Cancer Cell Lines

Background: Despite modern developments in its management, still major concerns remain about drug resistance in chemotherapy. Natural adjuvants combined with chemotherapy might be the answer. We examined the anti-cancer, anti-proliferative and synergistic effects of Sambucus nigra extract with cisplatin chemotherapy (CDDP) on MCF-7 and MDA-MB-231 human cancer cell lines. Methods: MCF-7 and MDA...

Daintain/AIF-1 (allograft inflammatory factor-1) promotes erythrocyte lysis and heme release probably via binding to hemoglobin.

Free heme is potentially cytotoxic, particularly in the presence of oxidants or activated phagocytes. Daintain/AIF-1 (allograft inflammatory factor-1) is a macrophage factor that has been implicated in the regulation of inflammation. In the present study, daintain/AIF-1 was found to induce cytolysis of erythrocytes, resulting in heme release in vitro. Furthermore, the interacting protein of dai...

CAPD peritonitis induces the production of a novel peptide, daintain/allograft inflammatory factor-1.

OBJECTIVES To study the occurrence of a novel macrophage-derived peptide, daintain/allograft inflammatory factor-1 (AIF-1), in dialysate from continuous ambulatory peritoneal dialysis (CAPD) patients at commencement and after a follow-up period of therapy and during peritonitis. In addition, we studied peptide production in response to bacterial stimulation of monocytes and macrophages. DESIG...

Intracellular GSH Alterations and Its Relationship to Level of Resistance following Exposure to Cisplatin in Cancer Cells

One of the major complications in cancer chemotherapy is the development of resistance, and cisplatin, as one of the important medicines in treatment regimens of different cancers is not excluded. One of the most described cellular defense mechanisms involved in resistance is glutathione (GSH) and in this study, the effects of cisplatin on the total intracellular GSH level (GSHi) in some sensit...
