miR-125a-5p inhibits cancer stem cells phenotype and epithelial to mesenchymal transition in glioblastoma

SUMMARY

OBJECTIVE

Glioblastoma (GBM) is a common type of cancer with high mortality. Epithelial to mesenchymal transition (EMT) plays a vital role in the development of glioblastoma. The aim of this study is to evaluate the role of miR-125a-5p in glioblastoma and in the tumorigenesis of chemotherapeutic drug-resistant cancer stem-like cells in brain glioma.

METHODS

The role of miR-125a-5p in the regulation of CSCs, EMT, migration, and invasion in glioblastoma was measured in this study.

RESULTS

We showed the roles of miR-125a-5p in the regulation of CSCs, EMT, migration, and invasion in glioblastoma. miR-125a-5p can inhibit the CSCs phenotype and EMT in glioblastoma cells. In addition, its over-expression can significantly regulate CSCs-associated genes and EMT-associated gene expression in glioblastoma cells.

CONCLUSIONS

We concluded that miR-125a-5p is one of the key microRNAs regulating CSCs and EMT programs in glioblastoma. The results suggested that miR-125a-5p might be a novel therapy target for glioblastoma.
