摘要： MicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs that have been found highly conserved among species. MiRNAs are able to negatively regulate gene expression through base pairing of 3’ UTRs of their target genes. Therefore, miRNAs have been shown to play an important role in regulating various cellular activities. Over the past decade, substantial evidences have been obtained to show that miRNAs are aberrantly expressed in human malignancies and could act as “OncomiRs” or “Tumor suppressor miRs”. In recent years, increasing number of studies have demonstrated the involvement of miRNAs in cancer metastasis. Many studies have shown that microRNAs could directly target genes playing a central role in epithelia-mesenchymal-transition (EMT), a cellular transformation process that allows cancer cells to acquire motility and invasiveness. EMT is considered an essential step driving the early phase of cancer metastasis. This review will summarize the recent findings and characterization of miRNAs that are involved in the regulation of EMT, migration, invasion and metastasis of cancer cells. Lastly, we will discuss potential use of miRNAs as diagnostic and prognostic biomarkers as well as therapeutic targets for cancer. 其他題名： J Biomed Sci 出版者： London: BioMed Central 出版日期： 2015-01-23 出處： Journal of biomedical science, 2015-01, Vol.22 (1), p.9-9, Article 9 資源來源： Publicly Available Content Database 版權： Chan and Wang; licensee BioMed Central. 2015 版權： COPYRIGHT 2015 BioMed Central Ltd. 識別號： ISSN: 1423-0127 識別號： ISSN: 1021-7770 識別號： EISSN: 1423-0127 識別號： DOI: 10.1186/s12929-015-0113-7 識別號： PMID: 25614041
