Purpose: Multidrug resistance is resistance to structurally unrelated anticancer agents. Large-scale expression analysis by using high-density oligonucleotide microarrays may provide information about new candidate genes contributing to MDR. This study demonstrates alterations in expression levels of several genes related to epithelial-mesenchymal transition (EMT) in paclitaxel, docetaxel, and doxorubicin resistant MCF-7 cells.
