Abstract

MicroRNAs (miRNA) regulate a number of cellular processes. Recent studies have indicated that these molecules function in the epithelial‑mesenchymal transition (EMT). However, the crucial systematic role of EMT and miRNAs together in glioblastoma (GBM) remains poorly understood. The present study demonstrated that EMT was closely associated with malignant progression and clinical outcome using three independent glioma databases (GSE16011, Rembrandt and The Cancer Genome Atlas). Furthermore, integrated analysis of miRNAs and mRNA profiling in 491 GBM samples revealed an EMT biological process associated with an miRNA profile (19 positively and 18 negatively correlated miRNAs). Among these miRNAs, miR‑95 and miR‑223 indicated a high level of functional validation, reflecting their positive correlation with EMT. Additionally, the upregulation of miR‑95, which was negatively correlated with EMT, inhibited cellular invasion in glioma U251 and LN229 cells and decreased the expression of the mesenchymal marker N‑catenin, whereas an miRNA positively correlated with EMT, miR‑223, exhibited the opposite effect. Therefore, the results of the present study could further enhance the current understanding of the functions of miRNAs in GBM, indicating that the EMT‑specific miRNA signature may represent a novel target for GBM therapy.
