Gene expression in PBMC from Multiple Sclerosis patients undergoing interferon beta therapy.

ABSTRACT: We studied the gene expression patterns in PBMC from relapsing remitting MS patients undergoing weekly IFN-ß-1a therapy. On the basis of two fold changes in expression levels and statistical analyses we selected a diagnostic set of 137 genes that were differentially expressed between pretreatment and IFN-ß-1a-treated MS patients. Some these 137 genes may provide the basis for lack of IFN-ß-1a response. Keywords: Drug response to Interferon beta therapy in Multiple Sclerosis patients.

Novel Biomarkers and Interferon Signature in Secondary Progressive Multiple Sclerosis

Project description:Transcriptome analysis of RNA samples from human PBMCs of IFN-beta-1a (Rebif) therapy in secondary progressive multiple sclerosis (SPMS) patients. Objective: Untreated multiple sclerosis is inflammatory, with decreased immune control and subnormal type I interferon (IFN) signaling. IFN-ß therapy corrects abnormal IFN-ß signaling, reduces inflammation on MRI, exacerbations, and disease worsening in relapsing-remitting MS (RRMS). For unclear reasons, secondary progressive MS (SPMS) exhibits waning attacks, relentless neurodegeneration, and diminished benefits of therapy. Methods: Peripheral blood mononuclear cells and serum were from 10 healthy controls (HC), 9 therapy-naive RRMS, 20 therapy-naïve SPMS, and 10 IFN-ß-treated SPMS patients after therapy washout and four hours after IFN-ß-1a injection. Global gene expression was assayed with sensitive RNA microarrays and multiplexed serum immune and neuroprotective protein assays. Results: Therapy-naive RRMS cells displayed 8,723 differentially expressed genes (DEG), compared to HC, vs. d only 3,936 DEG in therapy-naive SPMS. In SPMS, gene expression was subnormal in the WNT/ß-catenin pathway that suppresses inflammation and enhances blood-brain barrier integrity. Olfactory receptor (OR) genes, linked to lymphocyte migration, were overexpressed in RRMS (111 DEG), intermediate in SPMS (34 DEG) vs. HC, differentiating RRMS from SPMS (p < 0.007). IFN-ß injections in SPMS decreased expression of pro-inflammatory genes and increased anti-inflammatory, anti-oxidant metallothionein genes. Pro-inflammatory and anti-inflammatory protein levels were balanced in HC, disrupted in RRMS, and intermediate in SPMS. Interpretation: Aberrant gene expression seen in RRMS wanes in SPMS, paralleling fewer clinical exacerbations and diminished therapeutic responses. Novel biomarkers for SPMS suggest new targets to correct subnormal immune regulation and brain repair in this neurodegenerative disease.

Project description:The purpose of this study was to characterize the transcriptional effects induced by intramuscular IFN-beta-1a treatment (Avonex, 30 Âµg once weekly) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 24 MS patients within the first four weeks of IFN-beta administration. Keywords: Multiple sclerosis, Interferon, Pharmacogenomics, Affymetrix EDTA blood samples were taken from all patients immediately before first, second and fifth IFN-beta injection. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labelled and hybridized to Affymetrix Human Genome U133 A and B arrays to quantify the mRNA levels.

Expression data of multiple sclerosis patients receiving subcutaneous Interferon-beta-1a therapy [U133 Plus 2.0]

Project description:The purpose of this study was to characterize the transcriptional effects induced by subcutaneous IFN-beta-1a treatment (Rebif, 22 µg or 44 µg three times a week) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 12 MS patients within the first two years of IFN-beta administration. EDTA blood samples were taken from all patients immediately before first and second IFN-beta injection as well as after 1 month, 1 year and 2 years. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labeled and hybridized to Affymetrix Human Genome U133 Plus 2.0 arrays to quantify the mRNA levels. This GEO entry provides the U133 Plus 2.0 microarray data.

Transcriptional response to interferon beta-1a treatment in patients with secondary progressive multiple sclerosis

Project description:Interferon (IFN) beta-1a is an approved treatment for relapsing remitting multiple sclerosis (RRMS) and has been examined for use in secondary progressive multiple sclerosis (SPMS). However, no information regarding blood transcriptional changes induced by IFN treatment in SPMS patients is available. Our aim was to identify a subgroup of SPMS patients presenting a gene expression signature similar to that of RRMS patients who are clinical responders to IFN treatment.

Disease modifying therapy impacts on miRNA expression profiling in peripheral blood from Relapsing-Remitting Multiple Sclerosis patients

Project description:Multiple sclerosis (MS) is a chronic and progressive neurological disease. MS is characterized by early-stage neuroinflammation, neurodegeneration, and demyelination, with a spectrum of heterogeneous clinical manifestations in terms of disease course and response to therapy. The currently unsatisfied availability of diagnostic and prognostic biomarkers concerning disease progression and treatment response represents an important requirement for therapy individualization and drug efficacy. Specific Disease Therapies (DMTs) are available to prevent MS-related brain damage; however, the specific drug choice is still under debate and needs further characterization. Since differentially expressed miRNAs have been proposed as diagnostic tools in neurodegenerative/neuro-inflammatory diseases, such as multiple sclerosis, amyotrophic lateral sclerosis, and Alzheimer's disease, we characterized the miRNA expression profiling in peripheral blood mononuclear cells (PBMC) of subjects with relapsing-remitting MS treated with high efficacy DMTs: Cladribine (CLA, n=11 patients) or Ocrelizumab (OCRE, n=14 patients). The treated patients were compared to control (CTR) untreated subjects (n=15). Blood samples were collected from patients before treatment (time t0) and 6 months post-treatment (time t1), but just once from control subjects. CLA drug tablets were administered to the selected relapsing-remitting MS patients with a dosage of 1.75 mg/kg given for 5 days. OCRE drug was administered to the other relapsing-remitting MS patients by infusion with a dosage of 300 mg, twice in two weeks.

Pharmacogenomics of IFNb therapy

Project description:This experiment set is used for the manuscript entitled: Pharmacogenomics of Interferon-b therapy in multiple sclerosis: Baseline IFN signature determines pharmacological differences between patients. In this study we generated and analyzed pre- and post- IFNb treatment gene expression patterns of RRMS patients with the aim of identifying pre-existing and/or drug-induced signatures that will allow us to make predictions on the expected pharmacological effects of IFNb treatment. We show that the expression level of IFN response genes prior to treatment, determines the pharmacological differences between patients with MS at the molecular level. A group of 16 Dutch patients (10 females and 6 males) with clinically definite relapsing-remitting MS was recruited from the outpatient clinic of the MS Centre Amsterdam. Mean age at start of IFNb therapy is 40.6 +/- 7.7, mean EDSS is 2.3 +/- 1.3 (range 1-6). Blood samples were obtained just before treatment and 1 month after start of the therapy. Patients received Avonex, Betaferon, Rebif 22 or Rebif 44. A compound treatment design type is where the response to administration of a compound or chemical (including biological compounds such as hormones) is assayed.

Expression data of multiple sclerosis patients receiving Interferon-beta therapy

Project description:The purpose of this study was to characterize the transcriptional effects induced by subcutaneous IFN-beta-1b treatment (Betaferon, 250 µg every other day) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 25 MS patients within the first two years of IFN-beta administration. EDTA blood samples were drawn from all patients immediately before first, second, month 1, 12, and 24 IFN-beta injection. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labelled and hybridized to Affymetrix Human Genome U133 A and B arrays to quantify the mRNA levels.
