microRNAs carried by exosomes promote epithelial-mesenchymal transition and metastasis of liver cancer cells.

In this study, transforming growth factor-β1 treatment effectively induced epithelial-mesenchymal transition (EMT) of SMMC-7721 cells, and the expression and function of microRNAs (miRNAs) were determined to understand the processes involved in liver cancer metastasis. Nanoparticle tracking analysis and western blotting were performed to identify exosomes. Transwell and MTS assays were used to assess cell migration and proliferation, respectively.
