MicroRNA-124 (miR-124) is the most abundant miRNA in the brain. Biogenesis of miR-124 displays specific temporal and spatial profiles in various cell and tissue types and affects a broad spectrum of biological functions in the central nervous system (CNS). Recently, the link between dysregulation of miR-124 and CNS disorders, such as neurodegeneration, CNS stress, neuroimmune disorders, stroke,...

MicroRNA (miR)-124 has been implicated in malignant melanoma (MM). However, the detailed regulatory mechanism of miR-124 in the malignant phenotypes of MM cells has remained largely elusive. A total of 68 pairs of MM tissues and adjacent tissues were collected. Reverse-transcription quantitative polymerase chain reaction was used to examine the mRNA expression of versican as well as the express...

MicroRNAs (miRs) serve a role in promoting and suppressing tumors in various types of malignant cancer, such as cervical cancer. However, the regulatory mechanism of miR-124-3p in cervical cancer remains unclear. In the present study, miR-124-3p was significantly downregulated in cervical cancer tissues and cell lines compared with matching adjacent non-tumor tissues and the normal cervical epi...

miR-124 and Capn4 are aberrantly expressed in glioblastoma multiforme (GBM) tissues. In the present study, we investigated miR-124 and Capn4 expression in GBM tissue specimens. The role of miR-124 and Capn4 in the migration and invasion of glioma cells in vitro was also examined. miR-124 and Capn4 expression in 20 GBM and 6 control brain specimens was examined using RT-qPCR and immuno-blotting....

MicroRNA-124 (miR-124) has been reported to be downregulated in the cells exposed to hypoxia, which was confirmed in our study. We then used online microRNA target prediction tools to identify GRB2, SMAD5, and JAG1 as the candidate target genes of miR-124, and we next validated GRB2 as a direct gene by using luciferase reporter system. We also established the regulatory relationship between miR...

Insult-provoked transformation of neuronal networks into epileptic ones involves multiple mechanisms. Intervention studies have identified both dysregulated inflammatory pathways and NRSF-mediated repression of crucial neuronal genes as contributors to epileptogenesis. However, it remains unclear how epilepsy-provoking insults (e.g., prolonged seizures) induce both inflammation and NRSF and whe...

We read with great interest the work published by Dickstein et al. (1) showing that induced EVI1 expression in a murine model silences miR-124 expression by DNA methylation. The EVI1 gene codes for a transcription factor implicated in the development and progression of high-risk acute myeloid leukemia (AML) (2, 3). We quantify the expression of 250 microRNAs (miRNAs; TaqManHuman miRNA assay set...
