Epithelial-mesenchymal transition (EMT) is a morphological process in which epithelial cells transform into mesenchymal cells via a specific procedure. EMT plays an important role in the
cancer invasion-
metastasis cascade and the current treatment of metastatic
cancer, influences the migration, polarity, and adhesion of
tumor cells, promotes their migration, invasiveness, anti-apoptotic ability. It contributes to the changes of the tumor microenvironment and suppresses the sensitivity of
tumor cells to
chemotherapy, causing
cancer metastasis and worse, hindering the control and
therapy of it. This paper reviews the mechanisms, detection, and treatments of
cancer metastasis that have been identified and applied to date, summarizes the EMT-related biological molecules, providing a reference for EMT-targeted research and
therapy. As EMT is significant in the progress of
tumor metastasis, it is meaningful for the
therapy and control of metastatic
cancer to understand the mechanism of EMT at the molecular level. We summarized the mechanisms, detection and therapeutic implications of EMT, listed the research progress of molecules like genes,
miRNAs, signaling pathways in EMT. We also discussed the prospects of EMT-targeted treatment in
cancer metastasis interventions and the challenges the treatment and researches are facing. The summary is conducive to the treatment and further research of EMT and metastatic
cancer.
