(Submitter supplied) Background: MicroRNAs (miRNAs) are small, non-coding RNAs that regulate gene expression at the post-transcriptional level. miRNAs have emerged as important modulators of brain development and neuronal function and are implicated in several neurological diseases. Previous studies found miR-146a upregulation is the most common miRNA deregulation event in neurodevelopmental disorders such as autism spectrum disorders (ASD), epilepsy and intellectual disability (ID). more...

(Submitter supplied) by use of the model of human embryonic stem cell (hESC)-derived neurogenesis, miRNAs involved in the differentiation from neural stem cells (hNSC) to neurons were profiled and identified. HNSC were differentiated into the neural lineage, out of which the neuronal subset was enriched through cell sorting based on select combinatorial biomarkers: CD15-/CD29Low/CD24High. This relatively pure and viable subpopulation expressed the neuronal marker alpha III-tubulin. more...

(Submitter supplied) We performed microarray profiling of miRNA expression across the four principal cell types of the central nervous system: neurons, astrocytes, oligodendrocytes and microglia, isolated from rat cortex. Our microarray results showed that the four cell types differ extensively in their miRNA expression. Over one third of the 351 miRNAs examined had higher than 5-fold differences in expression between two of the four cell types. more...

(Submitter supplied) Normal SJL mice, 6 to 8 weeks old, were used for the isolation of bone marrow stem cells (BMSC). Bone marrow cells were obtained from the femurs and tibias of euthanized mice by flushing with PBS. Cells were subjected to negative magnetic sorting using the Lineage Cell Depletion Kit. Isolation of murine bone marrow Lin-Sca-1+ cells was performed using MACS Sca-1 MultiSort Kit (fBMSC). The differentiation of neural stem cells was induced by removing the bFGF-containing medium and resuspending cells in fresh bFGF-free medium. more...

(Submitter supplied) MicroRNAs (miRNA) play an essential role in the regulation of gene expression, influence signaling networks responsible for several cellular processes like differentiation of pluripotent stem cells. Despite several studies on the neurogenesis process, no global analysis of microRNA expression during differentiation of induced pluripotent stem cells (iPSC) to neuronal stem cells (NSC) has been done. Therefore we compared the profile of microRNA expression in iPSC lines and in NSC lines derived from them, using microarray-based analysis. Two different protocols for NSC formation were used: direct and two-step via neural rosette formation. We confirmed the new associations of previously described miRNAs in regulation of NSC differentiation from iPSC. We discovered upregulation of miR-10 family, miR-30 family and miR-9 family and downregulation of miR-302 and miR-515 family. Moreover we showed that miR-10 family play a crucial role in the negative regulation of genes expression belonging to signaling pathways involved in neural differentiation: WNT signaling pathway, focal adhesion, signaling pathways regulating pluripotency of stem cells.

Furthermore, ASD risk genes are enriched for FMRP (Fragile X Mental Retardation Protein) targets and for genes implicated in ID. In addition, a significant co-heritability was observed between ASD and SCZ. more...

(Submitter supplied) Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication deficits and repetitive behaviors. MicroRNAs (miRNAs) have been recently recognized as potential biomarkers of ASD as they are dysregulated in various tissues of individuals with ASD. However, it remains unclear whether miRNA expression is altered in individuals with high-functioning ASD. Here, we investigated the miRNA expression profile in peripheral blood from adults with high-functioning ASD, and age and gender-matched healthy controls. more...

(Submitter supplied) We report here the expression profile of microRNAs in human neuronal differentiation in the neuroblastoma cell line SH-SY5Y. Six microRNAs were significantly upregulated during differentiation induced by all-trans¬-retinoic acid and brain-derived neurotrophic factor. We demonstrated that ectopic expression of either miR-124a or miR-125b increases the percentage of differentiated SH-SY5Y cells with neurite outgrowth. more...

(Submitter supplied) Since the NFI transcription factors have been shown to be key regulators of gliogenesis, we utilized this pathway to identify miRNAs involved in the regulation of the neurogenesis-to-gliogenesis switch by neural stem/progenitor cells (NSPCs). We focused on miRNAs with expression levels that were differentially regulated downstream of NFIA, and established a mouse embryonic stem cell (ESC) line that expresses NFIA in a doxycycline (Dox)-dependent manner.

(Submitter supplied) Mammalian neural stem/progenitor cells (NSPCs) sequentially generate neurons and glia during central nervous system (CNS) development. Several transcription factors and microRNAs (miRNAs) are involved in the temporal regulation of NSPC differentiation. miRNA-153 (miR-153) as a modulator of NSPC specification. Overexpression (OE) of miR-153 delayed the onset of astrogliogenesis and maintained NSPCs in an undifferentiated state in vitro.

(Submitter supplied) Purpose: MBD5-Associated Neurodevelopmental Disorder (MAND) is an Autism Spectrum Disorder (ASD) disorder characterized by intellectual disability, motor delay, severe speech impairment and autism-like behavioral problems. The role of MBD5 in neurodevelopmental function remains largely undefined. In this study, we explored the neurodevelopmental phenotype of 2q23.1 deletion syndrome through creating neuronal progenitor stem cells (NPC) derived from 2q23.1 patients and conducting RNA-seq to identify the contributory altered gene and to expand our knowledge about gene network differences and possible interactions between the related disease pathways and ASD. more...

(Submitter supplied) A hallmark of cortical evolution is the high dynamic subventricular zone (SVZ) expansion, where basal progenitors (BPs) amplify and neuronal transcriptional programs unfold. How non-coding molecular factors such as microRNAs influence these developmental trajectories and regulate the acquisition of cortical type identities is largely unknown. Here we demonstrate that miR-137 and miR-122 regulate the positioning and identity features of superficial layer cortical neurons by acting at distinct steps of their developmental trajectories. more...
