Abstract: Distant metastasis of tumor cell is a series of continuous, selectable cascades of events regulated by multiple factors and genes. Epithelial-mesenchymal transition (EMT) is a critical step during cancer metastasis. However, the mechanism of EMT in tumor is not yet fully elucidated. MicroRNAs (miRNAs) are a class of non-coding small endogenous RNAs that negatively regulate EMT-related genes at the post-transcriptional level and play critical roles in cancer metastasis. This review mainly focuses on the topics that include the relationship of EMT and tumor metastasis, transcription factors involved in EMT, and the effect of miRNAs on tumor metastasis by targeting the EMT-related transcription factors.

Key words: microRNAs, tumor metastasis, epithelial-mesenchymal transition
