MicroRNA expression in pediatric intracranial ependymomas and their potential value for tumor grading

Original language description

Intracranial ependymoma represents one of the most common pediatric central nervous system malignancies, and exhibits a wide range of clinical behavior from relatively indolent lesions to highly malignant anaplastic ependymomas. Due to the heterogeneous nature of this disease there is lack of prognostic markers, which would reliably predict the outcome of patients. MicroRNAs (miRNAs) have emerged as important molecules in cancer biology during past decade; however, very little is known about their role in ependymomas. The aim of the present study was to evaluate expression of miRNAs in archived formalin-fixed paraffin-embedded (FFPE) samples of pediatric intracranial ependymomas. The expression of miRNAs were examined in 29 samples of ependymoma and we observed that miR-135a-3p, miR-137, miR-17-5p, miR-181d and let-7d-5p were upregulated. In addition, a significantly higher expression of miR-203a was detected in Grade III tumors suggesting its possible use as a prognostic or diagnostic marker. The present study also demonstrated that storage of (FFPE) ependymoma samples for &gt;20 years did not result in a deterioration of miRNAs. The present findings broaden the presently available knowledge regarding miRNA expression in ependymomas and provide further evidence for the employment of miRNA analysis as a supplementary method for the morphological assessment of ependymoma samples.
