Epithelial-mesenchymal transition (EMT) can directly contribute to some malignant phenotypes of tumor cells including invasion, metastasis and resistance to chemotherapy. Although EMT is widely demonstrated to play a critical role in chemoresistance and metastasis, the potential signaling network between EMT and drug resistance is still unclear. The distribution of drugs in the internal and external environment of the tumor cells is tightly linked with ATP-binding cassette (ABC) transporters. Recent studies have shown that ABC transporters expression changed continuously during EMT. We believe that EMT is an important regulator of ABC transporters. In this review, we discuss how EMT regulates ABC transporters and their potential linkages. And we hope the knowledge of EMT and ABC transporters will offer more effective targets to experimental research.
