Transcriptome-wide analysis of Agc1 downregulation in mouse oligodendrocyte precursor cells

Project description:Aspartate-glutamate carrier isoform 1 (Agc1) is a mitochondrial carrier part of the malate-aspartate shuttle, responsible for the export of aspartate and N-acetyl-aspartate from the mitochondria to the brain. Agc1 deficiency can cause an ultra-rare genetic disease reported as epileptic encephalopathy with global cerebral demyelination often caused by mutation in Slc25a12, the gene from which Agc1 is encoded. Symptoms of the disease include diffused hypomyelination, arrested psychomotor development, severe hypotonia, seizures and are common to other neurological and developmental disorders. Oligodendrocytes are glial cells responsible for myelination and remyelination and a disruption of acetyl fluxes can severely hamper their ability to form myelin leading to abnormal neuronal functionality. In this work, we explore the transcriptome of mouse oligodendrocyte precursor cells that have been silenced for Agc1 expression, reporting results of both canonical analyses such as differential expression and pathway enrichment analyses which highlight a disruption in fatty acids synthesis from both a regulatory and enzymatic stand. We further explore the transcriptome space with a network and an alternative splicing analysis: these results taken together highlight a severe alteration at the transcriptome level, which brought us to question a possible involvement of Agc1 in transcription regulation.

Investigation of Oligodendrocyte Precursor Cell Differentiation by Quantitative Proteomics

Project description:Oligodendrocytes, the myelinating cells of the central nervous system, are essential for correct brain function. They originate from oligodendrocyte precursor cells (OPCs) through a differentiation process which is only incompletely understood and impaired in a variety of demyelinating diseases. Better knowledge of this differentiation holds the promise to develop novel therapies for these disorders. We investigated the differentiation of rat oligodendrocyte precursor cells to oligodendrocytes in vitro. After confirmation of differentiation by immunohistochemical analysis using cell type-specific marker proteins, we conducted a quantitative proteomics study using tandem mass tags (TMT). We investigated four time points of differentiation covering early, intermediate, and late stages. Data analysis was perfomed using Mascot and Maxquant.

Expression profiles in Chd7 knockdown oligodendrocyte precursor cells

Project description:Oligodendrocytes are generated from oligodendrocyte precursor cells (OPCs). Chd7 is ATP-dependent chromatin-remodeling enzyme. We performed microarray analysis to examine changes in gene expression between control and Chd7 knockdown OPCs. Results provide insight into the function of Chd7 in oligodendrocyte development.

Transcriptomics of mouse oligodendrocyte precursor cells treated with microglia-derived extracellular vesicles

Project description:Myelin loss due to oligodendrocyte degeneration is a central feature of various neurodegenerative disorders and contributes significantly to neurological disability. Promoting endogenous myelin repair by enhancing oligodendrocyte precursor cell (OPC) differentiation represents a promising therapeutic strategy. Extracellular vesicles (EVs) secreted by pro-regenerative microglia have been shown to support OPC maturation and remyelination, yet the underlying molecular mechanisms remain incompletely understood. In this study, we performed transcriptomic profiling of primary murine OPCs undergoing differentiation in the presence of EVs derived from donor microglia exposed to pro-inflammatory cytokines (i-EVs), interleukin-4 (IL4-EVs), or mesenchymal stem cells (MSC-EVs). This dataset provides insights into the transcriptional changes associated with EV-mediated modulation of OPC differentiation.
