The epithelial-mesenchymal transition (EMT) has a significant role in embryogenesis. EMT is also implicated as a fundamental step development of invasive phenotypes associated with progression of cancer. EMT confers the cancer cells with migratory and invasive properties that allow them to come into the stroma, which creates a conducive environment for cancer progression and metastasis. Moreover, acquisition of EMT is linked with resistance to chemotherapy that could lead to recurrences and enhance the morbidity and mortality related to cancers. Consequently, EMT has been associated with carcinogenesis, invasion, metastasis, recurrence, and chemoresistance. Research into EMT and its role in cancer pathogenesis has advanced in a rapid pace, but since its participation shows considerable variation among different cancer types and the exact mechanism operative in different cancers remains ambiguous; EMT continues to be a significant issue for research. In this review, we present an overview of EMT, its role in cancer progression and the clinical implication of its identification.
