RNA-seq to investigate the adult mouse Muller glia transcriptome

ABSTRACT: These data serve as a reference transcriptomic profile for adult mouse retinal Muller glia. Retinas were dissociated into single cell suspensions and sorted into two fractions: a Muller glia-enriched fraction on the basis of Muller glia-specific tdTomato expression and a second fraction containing the remaining retinal cells that were tdTomato-negative. Both fractions were sequenced.

Transcriptome analysis of the uninjured Muller glia (MG) and MG derived retinal progenitors at 4 day post injured zebrafish retina

Project description:The study was aimed at comparing the transcriptome of MG cells of the retina with the progenitors derived from them after an injury. This information will help in the identification of factors that are responsible for the retinal regeneration. Muller glia were isolated by fluorescent activated cell sorting (FACS) using uninjured retinas from transgenice zebrafish (gfap:gfp) where green florescent protein (GFP) is under the control of the glial fibrillary acidic protein (gfap) promoter. MG-derived retinal progenitors were isolated by FACS at 4 days post retinal injury from 1016 tuba1a:gfp transgenic fish where GFP is driven by the tuba1a promoter which is specifically activated in these progenitors. Total RNA was isolated from these cell populations and subjected to microarray analysis to compare their transcriptomes. Samples were prepared in duplicate.

Ciliary neurotrophic factor induces genes associated with inflammatory response and gliosis in the retina: A gene profiling study of flow-sorted, Muller (glial) cells

Project description:Our data suggest that CNTF remodels the transcription profile of Muller (glial) cells leading to induction of networks associated with transcription, cell cycle regulation and inflammatory response. CNTF also appears to function as an inducer of gliosis in the retina. These studies provide new insights into the biological functions of cytokines in the retina. Muller glial cells treated with CNTF for 1 and 3 days

GENE EXPRESSION CHANGES WITHIN MM-CM-^\LLER GLIAL CELLS DURING RETINITIS PIGMENTOSA

Project description:Retinitis Pigmentosa (RP) is a progressive retinal degeneration in which the retina loses nearly all of its photoreceptor cells and undergoes major structural changes. Little is known regarding the role the resident glia, the MM-CM-<ller glia, play in the progression of the disease. Here we define gene expression changes in MM-CM-<ller glial cells (MGCs) from two different mouse models of RP, the retinal degeneration 1 (rd1) and rhodopsin knock-out (Rhod-ko) models. The RNA repertoire of 28 single MGCs was comprehensively profiled, and a comparison was made between MGC from wild type (WT) and mutant retinas. Two time points were chosen for analysis, one at the peak of rod photoreceptor death and one during the period of cone photoreceptor death. MGCs have been shown to respond to retinal degeneration by undergoing gliosis, a process marked by the upregulation of GFAP. In this data, many additional transcripts were found to change. These can be placed into functional clusters, such as retinal remodeling, stress response, and immune related response. It is noteworthy that a high degree of heterogeneity among the individual cells was observed, possibly due to their different spatial proximities to dying cells, and/or inherent heterogeneity among MGCs. Retinas were dissociated and single Muller Glial Cells were picked under a dissecting microscope using a micropipette based on their distinct morphological shape. Single cell cDNAs were generated and genome wide profiles were obtained by hybridization to Affymetrix 430 2.0 microarrays. Data was normalized using MAS5.0 software. A total of 28 Muller Glial Cells were analyzed and confirmed post hoc by expression of known marker genes.

miRNA expression data from CD73-positive Rods, MÃ¼ler glia and E 17.5 Retinal Progenitors

Project description:During retinal development, progenitor cells give rise to six different types of neurons, and one glial cell. This process requires the expression of genes that confer specific functions and identity to each cell. Previous works have reported the miRNAs expression profile in retina, but is still necessary to further define individual retinal cell populations profiles. We isolated postmitotic mice CD73-positive Rods, MÃ¼ller glial cells and Retinal Progenitors Cells (E17.5); we then analyzed their miRNA profile expression by microarrays. Using wild type mice we FACS-isolated postmitotic CD73-positive Rods (posnatal day 5). We isolated primary MÃ¼ller glia cultures from postnatal day 8 mice and retinal progenitors cells from E17.5 mouse embryos; we then sent the samples to the gene expression unit at Instituto de Medicina Genomica (INMEGEN), to analyze their miRNA profile expression by microarrays.

MicroRNA expression profile in mouse cone photoreceptors at P60 [miRNA-seq]

Project description:The outer segments of cones serve as light detectors for daylight color vision, and their dysfunction leads to human blindness conditions. We show that the cone-specific disruption of DiGeorge Syndrome Critical Region Gene 8 (DGCR8) in adult mice led to the loss of miRNAs and the loss of outer segments, resulting in photoreceptors with significantly reduced light responses. Using next-generation sequencing of RNA from isolated wild type P60 cones, we determine the most highly expressed miRNAs as candidates for controlling outer segment maintenance. The expression pattern of miRNAs was highly uneven, with a single miRNA, miR-182, representing 64% of all miRNA expressed in cones. Re-expression of miR-182 and miR-183 (third most abundant miRNA) prevented outer segment loss. These miRNAs were also necessary and sufficient for the formation of inner segments, connecting cilia and short outer segments, as well as light responses in stem-cell-derived retinal cultures. Our results show that miR-182- and miR-183-regulated pathways are necessary for cone outer segment maintenance in vivo and functional outer segment formation in vitro. microRNA profile in cone photoreceptors from P60 D4-cre/Ai9 tdTomato mice representing wild type control.

Single cell expression profiling of NG2 cell lineage from adult mice cortex three days after focal cerebral ischemia

Project description:Ischemic stroke is a serious medical condition that leads to neurological symptoms such as loss of motor and cognitive function. Focal cerebral ischemia (FCI) occurs due to interruption of blood supply to the site of injury, leading to the death of brain cells. Cells carrying Neural-glial antigen 2 (NG2) include glial cells serving primarily as olidogendrocyte precursors and a portion of pericytes. NG2 glia proliferate rapidly after ischemia and migrate to the site of injury, participate with astrocytes in glial scar formation, and contribute to the regeneration of the brain tissue. The ability of NG2 glia to differentiate into a different cell type than oligodendrocytes has been described but is still controversial. We therefore isolated NG2 cells and their derivatives labeled with tdTomato red fluorescent protein from the cortex of Rosa26-tdTomato/Cspg4-CreERT2 mice three days after middle cerebral artery occlusion (MCAO). Sham-operated animals were used as healthy controls (CTRL). We aimed to identify NG2 cell types and their derivatives in the cortex of healthy and ischemic mice and determine their incidence as well as characteristic gene expression.

Whole transcriptome analysis of FACS purified somatosensory neuron subtypes and whole dorsal root ganglia tissue

Project description:The goal of this study was to analyze global gene expression in specific populations of somatosensory neurons in the periphery, including major, non-overlapping populations that include nociceptors, pruriceptors, and prorioceptors. The mammalian somatosensory nervous system encodes the perception of specific environmental stimuli. The dorsal root ganglion (DRG) contains distinct somatosensory neuron subtypes that innervate diverse peripheral tissues, mediating the detection of thermal, mechanical, proprioceptive, pruriceptive, and nociceptive stimuli. We purified discrete subtypes of mouse DRG somatosensory neurons by flow cytometry using fluorescently labeled mouse lines (SNS-Cre/TdTomato, Parv-Cre/TdTomato) in combination with Isolectin B4-FITC surface staining (IB4). This allowed identification of transcriptional differences between these major populations, revealing enrichment of voltage-gated ion channels, TRP channels, G-protein coupled receptors, transcription factors, and other functionally important classes of genes within specific somatosensory neuron subsets. SNS-Cre mice were bred with Rosa26-TdTomato mice to generate SNS-Cre/TdTomato reporter mice. Parv-Cre mice were bred with Rosa26-TdTomato mice to generate Parv-Cre/TdTomato mice. Isolectin B4-FITC was used to stain the surface of SNS-Cre/TdTomato reporter mice. We used these strategies of fluorescent labeling to purify distinct murine sensory neuron subsets from the dorsal root ganglia (DRG) by fluorescence activated cell sorting (FACS). Neurons were sorted directly in Qiazol for total RNA extraction and microarray analysis. Whole DRG tissue was also included for transcriptome analysis to compare with purified neuronal populations.
