Project description:A genetic study of the PRF1 gene has shown association of several polymorphisms with multiple sclerosis (MS). Haplotype analysis identified risk haplotypes strongly associated with male patients having the primary-progressive form of MS (PPMS). Gene expression microarrays were performed in 10 male PPMS patients carrying the risk (n=6) and protective haplotypes (n=4) in order to identify pathways associated with the risk haplotypes. Pathway analysis revealed overrepresentation of the cell killing gene ontology category among down-regulated genes in patients carrying risk haplotypes compared with patients carrying protective haplotypes.

Project description:Transcription profiling of peripheral blood from patients with primary progressive multiple sclerosis to compare risk and protective PRF1 haplotypes

Project description:We analyzed the transcriptome profile of B cells from patients with relapsing-remitting multiple sclerosis (RRMS), patients with primary progressive multiple sclerosis (PPMS) and healthy individuals. High-density Clariom D Arrays for human were used to quantify the transcript levels. This GEO entry provides the processed Clariom D microarray data from the gene-level and exon-level workflows.

Project description:One of the most challenging aspects in multiple sclerosis (MS) research is to understand the mechanisms leading to neurodegeneration and subsequent tissue repair. Here, we aimed to identify biomarkers associated with the progressive phases of the disease that may have neuroprotective potential. To achieve this, we performed a bioinformatic approach integrating transcriptional and proteomic profiles obtained during the course of experimental autoimmune encephalomyelitis (EAE) combined with gene expression microarray data from neuronal differentiation. Integrative analysis of omics data identified two molecules, serine (or cysteine) peptidase inhibitor, clade A, member 3N (Serpina3n) and S100 calcium binding protein A4 (S100A4), as biomarkers up-regulated in chronic progressive EAE whose expression was also induced during neuronal differentiation. Immunofluorescence studies revealed a primarily neuronal expression of Serpina3n and S100A4 during EAE as reflected by their co-localization with β-III-Tubulin in neurons from cerebellum, hippocampus and spinal cord tissues during EAE. Finally, levels of SERPINA3, the human ortholog of murine Serpina3n also known as α1-antichymotrypsin, and S100A4 were increased in cerebrospinal fluid of MS patients compared with non-inflammatory neurological controls. However, only SERPINA3 showed differences across MS clinical forms and levels were significantly elevated in patients with progressive forms of the disease, particularly in patients with primary progressive MS, compared with relapsing-remitting MS and neurological controls. Altogether, these results point to a role of SERPINA3 as biomarker associated with the progressive forms of MS that may also have neuroregenerative potential

Project description:The transcriptome of normal-appearing white matter for relapse-remitting multiple sclerosis (MS), primary progressive MS and secondary progressive MS was determined using total RNA-sequencing. We then performed a differential gene analysis comparing the normal-appearing white matter for each clinical subtype of MS with non-MS control tissue

Project description:There have been few studies that have focused on the periplaque regions surrounding demyelinated plaques, especially in spinal cords. Areas of incomplete demyelination have been demonstrated but poorly studied. The present study aimed to analyze the molecular immunopathology of periplaque demyelinated lesions (PDLs) in the spinal cord of patients with secondary progressive multiple sclerosis (MS). To achieve this goal, the transcriptomic profiles of PDLs were analyzed in post-mortem tissues derived from the cervical spinal cord of 8 patients with primary or secondary progressive MS. Sixteen spinal cord samples were microdissected for RNA extraction and hybridization on Affymetrix microarrays. Eight periplaque samples (P) were compared to normal appearing white matter (N) from the same patient.
