Expression data of sciatic nerves from mice with Schwann-cell specific Sip1 deletion compared to control mice.

Project description:Schwann cell maturation is tightly controlled by a set of transcriptional regulators. We have deleted the zinc-finger transcription factor Sip1 specifically from immature Schwann cells and observed a dramatic developmental delay. In an attempt to define the developmental stage of Sip1-deficient Schwann cells, we performed microarray analysis of Schwann cell-specific mutants compared to controls at the age of 25 days (P25). Sciatic nerves of 3 mutant mice and 3 corresponding controls were isolated at the age of 25 days.

RNA-seq analysis lncRNA and mRNA between crushed sciatic nerves and intact contralateral nerves

Project description:To investigate the potential function of lncRNAs in Schwann cell (SCs) response to sciatic nerve damage and repair, we extracted the total RNA of crushed sciatic nerves and intact contralateral nerves for RNA-sequencing (RNA-seq). A total of 98 differentially expressed lncRNAs (including 46 up-regulated and 52 down-regulated lncRNAs) and 77 differentially expressed mRNAs (including 55 up-regulated and 22 down-regulated mRNAs) were identified between crushed sciatic nerves and normal control (log 2 FC > 1 and p < 0.001).

Gene expression comparison between Ebf2 -/- and WT P2 Sciatic nerves

Project description:Ebf genes regulate differentiation of several cell type. Ebf2 is expressed in Schwann cells and Ebf2-/- mice show among other phenotypical abnormalities a delay in the onset of myelination associated to a decreased expression of genes regulating myelination. In addition at one month of age Ebf2-/- mice show decreased motor conduction velocity and morphological alteration in sciatic nerves. Ebf2 target genes are unknown. To identify Ebf2 target genes with a role in myelination, we compared the expression profiles of sciatic nerves isolated from P2 Wt and Ebf2-/- mice by microarray analysis. We used microarray to find Ebf2 candidate target genes by comparing gene expression of Ebf2-/- sciatic nerve and wt nerves 2 days postnatally (P2) a time point in which Ebf2-/- pups present a delay in the onset of myelination.

RNA sequencing of control and dnm2-knockout mouse sciatic nerves

Project description:In this study, we analyzed the transcriptome profiles of mouse sciatic nerves after developmental (P1 and P5) or inducible (4 weeks post Tamoxifen) deletion of Dnm2 conditionally in Schwann cells (using a P0Cre-driven or a P0CreERT2-driven recombination of floxed alleles, respectively) as compared to controls (floxed Dnm2 homozygous, Cre-negative).

RNA sequencing of control and raptor-knockout mouse sciatic nerves after crush injury

Project description:In this study, we analyzed the transcriptome profiles of mouse sciatic nerves subjected to crush injuries after inducible deletion of Raptor conditionally in Schwann cells (using a PLPCreERT2-driven recombination of floxed alleles) as compared to controls (floxed Raptor homozygous, PLPCreERT2-negative). The transcriptome profiles of the contralateral uninjured nerves were also analyzed. Differentially expressed genes, defined as genes with a fold change>1.2 and fold discovery rate <0.05, in injured and contralateral nerves of mutants compared to controls were subjected to gene ontology analysis. Additionally, differentially expressed genes in injured mutants nerves as compared to injured control nerves were further analyzed for enrichment of transcription factor binding motifs in the corresponding promoter regions using the bioinformatic tool Homer version 4.9 (Heinz et al., Molecular Cell, 2010)

SNAT - Single cell RNA sequencing of mouse cells sorted from sciatic nerves at postnatal day 1 (P1) and P60

Project description:Sciatic nerves from P1 and from P60 mice were dissociated, and the resulting cell suspension was sorted with FACS. All cells positive for beta-actin dsred (including Schwann cells also expressing eYFP due to P0Cre-mediated recombination) were collected for RNA sequencing with 10X Genomics.

RNA sequencing of sciatic nerves from ZH3 and WT mice

Project description:The transcriptome of sciatic nerves was investigated by RNA sequencing. We compared the transcriptome of ZH3 sciatic nerves to WT sciatic nerves in two age groups. Differentially expressed genes were considered as indicators of peripheral nerve damage in ZH3 mice. Then, we compared the sciatic nerve transcriptome of ZH3 mice chronically treated with a dimeric PrP-fusion protein (FT2Fc) to the two control groups treated with either buffer or mouse IgG. This comparison revealed specific changes induced by FT2Fc treatment. Contrary to our hypothesis, FT2Fc treatment did not alter the expression of the genes that were dysregulated in young and old ZH3 mice (as identified in the first part of the study).

Functions of HDAC1 and HDAC2 in Schwann cells during postnatal

Project description:The aim of our study is to determine the functions of histone deacetylases (HDACs) 1 and 2 in Schwann cells during postnatal development of the peripheral nervous system (PNS). Schwann cells are the myelinating glial cells of the PNS. At birth, mouse sciatic nerves mature in 2 subsequent phases: 1/ big caliber axons get sorted into a 1 to 1 relationship with Schwann cells, 2/ Schwann cells build a myelin sheath around sorted axons. In mice where both HDAC1 & HDAC2 have been specifically knocked out in Schwann cells, both phases are impaired. HDACs are chromatin remodeling enzymes, they can thus alter gene expression directly. We want to identify which genes controlled by HDAC1 and HDAC2 in Schwann cells are necessary for the maturation of sciatic nerves. Because HDAC1 and HDAC2 can compensate for each other loss to some extend, we will first analyze changes of gene expression in HDAC1/HDAC2 double KO animals. We expect to gain critical insights into the molecular mechanisms controlling Schwann cell differentiation and myelination. This knowledge is of key importance for the success of regenerative medicine in peripheral neuropathies, nerve tumors, and transplantation paradigms in non-regenerative CNS lesions and in large PNS injuries. 3 double knockout mutants for HDAC1 and HDAC2 and 3 control littermates were analyzed. Tissues analyzed: sciatic nerves of 2 day-old mouse pups
