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

ABSTRACT: 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.

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

Project description: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.

Defective structural RNA processing in relapsing-remitting multiple sclerosis

Project description:It is fundamentally unknown how normal cellular processes or responses to extracellular stimuli may invoke polyadenylation and degradation of ncRNA substrates or if human disease processes exhibit defects in polyadenylation of ncRNA substrates as part of their pathogenesis. Our results demonstrate that mononuclear cells from subjects with relapsing-remitting multiple sclerosis (RRMS) exhibit pervasive increases in levels of polyadenylated ncRNAs including Y1 RNA, 18S and 28S rRNA, and U1, U2, and U4 snRNAs and these defects are unique to RRMS. Defects in expression of both Ro60 and La proteins in RRMS appear to contribute to increased polyadenylation of ncRNAs. Further, IFN-β1b, a common RRMS therapy, restores both Ro60 and La levels to normal as well as levels of polyadenylated Y1 RNA and U1 snRNA suggesting that aberrant polyadenylation of ncRNA substrates may have pathogenic consequences. We extracted RNA from peripheral whole blood in healthy control subjects and patients with established relapsing-remitting multiple sclerosis using PaxGene tubes.

Attention to time-of-day variability improves the reproducibility of gene expression patterns in multiple sclerosis

Project description:Most biomarkers for the diagnosis and prognosis of multiple sclerosis (MS) are not yet clinically available due to low reproducibility. Here, we show that times of day affect gene expression profiles in MS patients. Thus sample collection has to be standardized based on the time-points biomarkers are expressed to increase reproducibility. In this study, we examined transcriptome profiles in whole blood of MS patients collected at two different time-points of the day, around 2 pm as the daytime and 9 pm as the nighttime. We observed the significantly changed gene expression profiles in the relapsing patients at nighttime compared to their daytime samples and the remitting patients at nighttime. Among all DEGs, we focused on differentially expressed genes (DEGs) related to immune responses because of association with clinical outcomes of MS. 68 immune responses-associated DEGs significantly changed their expression in the relapsing patients at nighttime but not in their daytime samples and remitting patients at nighttime. Therefore, this study shows that: 1) gene expresion patterns in relapsing patients are changed compared to remitting patients; 2) altered gene expression patterns in relpasing patients are detected at nighttim; 3) times of day to collect samples from MS patients should be standardized based on the gene expression patterns across a day.

Data in support of Temporal changes of inflammation and endothelial dysfunction in multiple sclerosis related to the evolution of enhancing lesions on frequent brain MRI

Project description:Blood-brain-barrier (BBB) breakdown and active inflammation by relapsing–remitting (RRMS) lesions are hallmarks of multiple sclerosis (MS). Leaky endothelial junctions causes an increased expression of circulating immune cells with associated adhesion molecules on endothelial cell membrane but also an increased production of endothelial derived extracellular microvesicles (EV). Methods: Relapsing–remitting MS (RRMS) patients with no disease-modifying treatment were monitored with weekly intervals using high-resolution 3T MRI scanning. Plasma samples from each measurement were analyzed for protein biomarkers of inflammation by quantitative proteomics, cytokines and chemokines using multiplex immunoassay. Extracellular microvesicles were characterized by an optimized endothelial stress EV Array analysis for detection of soluble secreted microvesicles.
