The aim of this study was to characterize the involvement of EPH receptors and ephrin ligands in mediating artesunate (ART)-induced growth suppression of normal breast cells and breast carcinoma cell lines. Materials and Methods: The normal breast epithelial cells (MCF10A), non-invasive ductal breast carcinoma cells (MCF7), and invasive triple-negative breast carcinoma cells (MDA-MB-231) were grown in the absence or the presence of different concentrations of artesunate. The cells were counted, and total RNA was isolated. The abundance of transcripts corresponding to EPH receptors and ephrin ligands was determined by quantitative polymerase chain reaction. Results: Cell viability was significantly reduced when cells were treated with artesunate, with MDA-MB-231 cells having the highest sensitivity. Artesunate had no significant effect on transcription of EPH/ephrins in MCF10A cells, but markedly increased EPHA8, EPHA10, EPHB6 and ephrin-A2 expression in MCF7 cells, and significantly increased EPHA3 and EPHA10 expression while reducing that of EPHA7 and ephrin-A3 in MDA-MB-231 cells. Conclusion: The relative changes in artesunate-treated MCF7 and MDA-MB-231 cells as compared to similarly treated MCF10A cells allow us to implicate combinatorial expression and receptor interactions for EPH receptor-mediated signal transduction that converges into pathways responsible for cell growth, proliferation, and apoptosis. Specifically, the alterations in EPHA7, EPHA8, EPHA10 and EPHB6 transcripts appear to be important participants in artesunate-mediated cellular effects.
