Abstract
- Objective Approximately 80% of glioma patients will experience at least one seizure activity during the course of the disease, and because the etiology of glioma-related seizure is most likely multifactorial and complex, it remains poorly understood. MicroRNAs are a class of small noncoding RNAs that function as critical gene regulators. MicroRNA-128 was found to be decreased in glioblastoma, and knockout of the microRNA-128a gene could induce epilepsy in mice. Based on the Chinese Glioma Genome Atlas and previous study, we hypothesized that dysregulation of miR-128 expression may play a role in the pathogenesis of TAE in low-grade glioma. Methods Fifty-three low-grade glioma samples were analyzed for the expression levels of miR-128 using qRT-PCR, and candidate targets of miR-128 (Cacnge2, GRIK3, and GRIN2D) were detected by the 3′-UTR luciferase reporter assay. Four other miRs (miR-9, miR-192a, miR-92a, and miR-451) that showed dysregulation of glioblastoma in the CGGA data were also analyzed. Results The microRNA-128 expression levels were down-regulated in low-grade glioma tissue ( t -test; p = 0.009). Dysregulation of miR-128 expression in low-grade glioma is associated with glioma-associated epilepsy (p = 0.006). No statistical significance of miR-9, miR-192a, miR-92a, and miR-451 was found to be associated with LGG. Conclusion Our results here, together with other recent lines of evidence, indicate that miR-128 is an extremely attractive target for therapy in glioma patients with seizure. [ABSTRACT FROM AUTHOR]
