[Advances in the molecular mechanisms and prognostic significance of EMT in non-small cell lung cancer].

Epithelial to mesenchymal transition (EMT) has an important role in the development of embryo, as well as that in the metastasis of non-small cell lung cancer (NSCLC). Recent researches have demonstrated that both morphological and phenotypic conversions emerge in cells undergoing EMT. As most of relevant studies were on other cancers, it is essential to uncover whether it is the similar mechanisms accounting for EMT in NSCLC. With the progress of the studies, EMT-related basic researches are gradually applied to predicting the prognosis of NSCLC. The aim of this article was to discuss the mechanisms related to EMT emerging in NSCLC.
