MicroRNAs (miRNAs) have been demonstrated to be important in the development and progression of various types of cancer. However, the exact roles of certain anti‑oncogenic miRNAs in human malignant gliomas remain to be elucidated. The present study aimed to reveal the expression of microRNA‑203 (miR-203) in normal brain tissues and gliomas, and to investigate the role of miR-203 in cell proliferation and migration in human glioblastoma U251 cells. Real-time reverse transcription polymerase chain reaction (RT-PCR) showed that the expression of miR-203 in high WHO grade glioma tissues was significantly decreased compared with low WHO grade glioma tissues and normal brain tissues, and its expression demonstrated a decreasing tendency with ascending WHO grades. The transfection of the miR-203 mimic into U251 cells markedly downregulated the expression of phospholipase D2 (PLD2), which was identified as a direct target of miR-203. Furthermore, miR-203 overexpression significantly suppressed the proliferation and invasion of U251 cells, while the overexpression of PLD2 abrogated these effects induced by the miR-203 mimic. In conclusion, the present study demonstrated the clinical significance of miR-203 in gliomas and suggested that miR-203 was able to inhibit the proliferation and invasion of glioma cells, partially at least via suppressing the protein expression of PLD2. Thus, miR-203 may be a novel candidate for the development of therapeutic strategies for gliomas.
