Summary:
In spite the heavy investments in therapeutic research breast cancer still impacts the lives of women globally. The projected incidence of new cases in USA for 2008 is 67,770, with estimated 40,480 deaths. In this study, we investigated the therapeutic efficacy of Cytoreg®-genistein combination treatment on MCF-7 human breast cancer cells. MCF-7 cells were treated with genistein and Cytoreg® single and combination treatments for 24- 48hr; and the chemosensitivity assessed using bioassays: Trypan Blue and MTT for cell viability; Ethidium bromide/Rhodamine 123 to assess apoptosis induction; F AM PolyCaspase binding assay for mechanism of action. The overall data indicated dose- and timedependent cell death in the MCF-cells and that apoptosis was the major means of treatmentinduced growth inhibition. There was evidence of Cytoreg®-induced autophagy in the cells. The overall findings indicated that genistein-Cytoreg® combination was more efficacious than either genistein or Cytoreg® alone. Cytoreg® enhanced the phytosensitivity of MCF-7 cells to genistein isoflavone.
