MiR-195 inhibits migration, invasion and epithelial-mesenchymal transition (EMT) of endometrial carcinoma cells by targeting SOX4.
MicroRNAs (miRNAs) have been identified as potential biomarkers for endometrial carcinoma (EC) diagnosis, prognosis and therapy. The purpose of the present study was to investigate the detailed role and molecular mechanism of miR-195 in EC metastasis. qRT-PCR assay was performed to assess the expression of miR-195 and SRY-related high-mobility group box 4 (SOX4) mRNA in EC tissues and cells. The levels of N-cadherin, Vimentin, E-cadherin and SOX4 protein were determined by western blot. ⋯ MiR-195 overexpression-mediated anti-migration, anti-invasion and anti-EMT effects were antagonized by SOX4 restoration in EC cells. In conclusion, our study suggested that miR-195 inhibited the migration, invasion and epithelial mesenchymal transition (EMT) of EC cells at least partly by targeting SOX4. Our study provided a novel underlying mechanism for EC metastasis and a promising therapeutic target for EC management.
