Project description:Background：CircRNAs are non-coding RNA molecules that have recently been described and shown to regulate miRNA functionality. While recent studies have suggested such circRNAs to be associated with pain related diseases in humans, no comprehensive migraine-related circRNA profiles have been generated and there is currently no clear understanding of whether they can serve as regulators of migraine pathology. Methods:We initially conducted a circRNA microarray analysis of the plasma of migraine patients and healthy controls. Based upon these data, we then selected 8 differentially expressed circRNAs and confirmed their expression in more migraine patient plasma samples via real-time PCR. We then performed functional and pathway enrichment analyses. Lastly, using a robust rank aggregation approach, we constructed a ceRNA network according to predicted circRNA–miRNA and miRNA–mRNA pairs in these migraine patient samples. Results:we were able to detect 2039 circRNAs in our patient samples, with and 794 of 1245 these circRNAs being up- and down-regulated in migraine patients relative to controls, respectively (fold change ≥1.5, P < 0.01). A qRT-PCR analysis confirmed that the expression of hsa_circRNA_100236, hsa_circRNA_102413, and hsa_circRNA_000367 was significantly enhanced in migraine patients, whereas the expression of hsa_circRNA_103809, hsa_circRNA_103670, and hsa_circRNA_101833 was significantly reduced in these individuals relative to healthy controls. We found these differentially regulated circRNAs to be associated with numerous predicted biological processes, with enrichment analyses suggesting that they may modulate PI3K-Akt signaling so as to promote inflammation to drive migraine development. However, further research will be needed to formally test these mechanistic possibilities and to validate these circRNAs as potential biomarkers of migraine patients.Conclusions: our results offer new potential insights into the mechanistic basis of this condition, and suggest that hsa_circRNA_000367 and hsa_circRNA_102413 may offer value as regulators of migraine pathology.

Project description:Migraine is primarily mediated via CGRP signaling on various tissues to induce pain and other migraine symptoms. We characterize the role of migraine related CGRP signaling on meningeal lymphatic vessels from mouse meningeal lymphatic tissue. In this dataset, we include the expression data obtained from lyve-1 positive meningeal lymphatic endothelial cells from Lyve-1 cre mediated HA-tagged ribosomes from mice with the NTG mediated model of migraine. These data are used to obtain 700 genes that are differentially expressed in meningeal lymphatic tissue in response to NTG induced migraine.

Project description:To investigate which miRNAs regulate the vestibular compensation after unilateral vestibular deafferentiation (UVD), we have performed microarray for miRNAs as a discovery platform. UVD induces breakdown of the activity of ipsilesional vestibular nuclei and an unbalance of activity between bilateral vestibular nuclei. Vestibular compensation is a course of rebalancing of activities of bilateral vestibular nuclei. It takes place mainly in medial vestibular nucleus. This study was performed using seven week-old-male Sprague–Dawley rats. Based on our previous experiment about vestibular compensation course, we set two time points for harvesting medial vestibular nuclei: 4hr and 4 days after unilateral vestibular deafferentiation. Twenty four animals were divided into two experimental groups: UVD group undergoing UVD at left side (n = 12); and SO group undergoing sham operation (SO) at left side (n=12). Six animals of each group were anesthetized deeply and euthanized at 4 hr or 4 days after surgery, respectively. Medial vestibular nucleus at left side was harvested. Medial vestibular nucleus from three animals became one sample for microarray. Sequentially two samples were obtained for each time point in one group. Microarray for miRNAs was performed using the Agilent Rat miRNA Microarray 8x15K platforms. Considering the fold change of normalized signal intensities between two time points in UVD group and between UVD and SO groups at the same time, miR-31a-5p, 133a-3p, 133b-3p, 204-5p, 206-3p, 218a-5p, 219a-5p, 221-3p and 497-5p were selected as the candidate miRNAs. This result was validated by quantitative reverse transcription-PCR.

Project description:Vestibular Schwannomas are benign neoplasms that arise from the vestibular nerve. The hallmark of these tumors is the biallelic inactivation of NF2. Transcriptomic alterations, such as the Nrg1/ErbB2 pathway, have been described in Schwannomas. Here, we have performed a whole transcriptomic analysis in 31 vestibular Schwannomas and 9 control nerves in the Affymetrix Gene 1.0ST platform, validated by quantitative Real-Time PCR using TaqMan Low Density Arrays. We performed a mutational analysis of NF2 by PCR/dHPLC and MLPA as well as a microsatellite marker analysis of the loss of heterozygosity of chromosome 22q. The microarray analysis showed that 1516 genes were deregulated, and 48 of the genes were validated by qRT-PCR. At least two genetic hits (allelic loss and/or gene mutation) in NF2 were found in 16 tumors, seven cases showed one hit and eight tumors showed no NF2 alteration. As conclusion, MET and associated genes such as ITGA4/B6, PLEXNB3/SEMA5 and CAV1 showed a clear deregulation in vestibular Schwannomas. In addition, androgen receptor (AR) downregulation may denote a hormonal effect or cause in this tumor. Furthermore, the osteopontin gene (SPP1), which is involved in Merlin protein degradation, was upregulated, which suggests that this mechanism may also exert a pivotal role in Schwannoma Merlin depletion. Finally, no major differences were found between tumors of different sizes, histological types or NF2 status, which suggests that at the mRNA level all Schwannomas, regardless of molecular and clinical characteristics, may share common features that can be used in the fight against them. In order to find target to fight against vestibular schwannoma, we performed an analysis of gene expression by microarrays.

Project description:Familial Hemiplegic Migraine type 1 (FHM1) is a rare monogenic subtype of migraine with aura caused by mutations in CACNA1A that encodes the a1A subunit of voltage-gated CaV2.1 calcium channels. Transgenic knock-in mice that carry the human FHM1 R192Q missense mutation (“FHM1 R192Q mice”) exhibit an increased susceptibility to cortical spreading depression (CSD), the mechanism underlying migraine aura. Here we analysed gene expression profiles from isolated cortical tissue of FHM1 R192Q mice 24 hours after experimentally induced CSD in order to identify molecular pathways affected by CSD. Gene expression profiles were generated using deep Serial Analysis of Gene Expression sequencing. Our data reveal a signature of inflammatory signalling upon CSD in the cortex of both mutant and wild-type mice. However, only in the brains of FHM1 R192Q mice specific genes are up-regulated in response to CSD that are implicated in interferon-related inflammatory signalling. Our findings show that CSD modulates inflammatory processes in both wild-type and mutant brains, but that an additional unique inflammatory signature becomes expressed after CSD in a relevant mouse model of migraine.
