Abstract
BACKGROUND Multiple sclerosis (MS) is a progressive neurodegenerative disease of the central nervous system (CNS) with varying degrees of axonal and neuronal damage. The onset and progression of the disease are influenced by several environmental and genetic variables. Long non-coding RNAs (lncRNAs) have a crucial role in the pathophysiology of MS. Our study aimed to assess the levels of HAR1A and HAR1B lncRNA expression in the blood samples of MS patients and investigate the relationship between these lncRNAs and disease activity. METHODS AND RESULTS The blood samples of 100 MS patients, including 82 relapsing-remitting (RR), 8 primary progressive (PP), and 10 secondary progressive (SP) MS cases, and 100 healthy controls were collected. Quantitative real-time PCR was used for the evaluation of gene expression. ROC curve analysis was performed to evaluate the diagnostic potential of lncRNA levels. A significant decrease was detected in HAR1A expressions (P < 0.0001), and a moderate increase was also shown in HAR1B of SPMS patients (P value = 0.0189). HAR1A showed different expression levels in patients over forty (P value = 0.034). The expression levels of HAR1A and HAR1B were positively correlated in MS patients (r = 0.2003, P value = 0.0457). In addition, ROC curve results suggested that HAR1A can be introduced as a novel biomarker for MS diagnosis (AUC = 0.776). CONCLUSION The low serum level of HAR1A may be a potential molecular biomarker for MS diagnosis; however, no discernible difference was detected in the expression level of HAR1B in the blood samples of MS patients.

Abstract
PURPOSE For many patients, the multiple sclerosis (MS) diagnostic process can be lengthy, costly, and fraught with error. Recent research aims to address the unmet need for an accurate and simple diagnostic process through discovery of novel diagnostic biomarkers. This review summarizes recent studies on MS diagnostic fluid biomarkers, with a focus on blood biomarkers, and includes discussion of technical limitations and practical applicability. RECENT FINDINGS This line of research is in its early days. Accurate and easily obtainable biomarkers for MS have not yet been identified and validated, but several approaches to uncover them are underway. Continue efforts to define laboratory diagnostic biomarkers are likely to play an increasingly important role in defining MS at the earliest stages, leading to better long-term clinical outcomes.

Cerebrospinal fluid proteome shows disrupted neuronal development in multiple sclerosis. Sci Rep 2021; 11:4087. [PMID: 33602999 PMCID: PMC7892850 DOI: 10.1038/s41598-021-82388-w] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 01/18/2021] [Indexed: 12/11/2022] Open
Abstract
Despite intensive research, the aetiology of multiple sclerosis (MS) remains unknown. Cerebrospinal fluid proteomics has the potential to reveal mechanisms of MS pathogenesis, but analyses must account for disease heterogeneity. We previously reported explorative multivariate analysis by hierarchical clustering of proteomics data of MS patients and controls, which resulted in two groups of individuals. Grouping reflected increased levels of intrathecal inflammatory response proteins and decreased levels of proteins involved in neural development in one group relative to the other group. MS patients and controls were present in both groups. Here we reanalysed these data and we also reanalysed data from an independent cohort of patients diagnosed with clinically isolated syndrome (CIS), who have symptoms of MS without evidence of dissemination in space and/or time. Some, but not all, CIS patients had intrathecal inflammation. The analyses reported here identified a common protein signature of MS/CIS that was not linked to elevated intrathecal inflammation. The signature included low levels of complement proteins, semaphorin-7A, reelin, neural cell adhesion molecules, inter-alpha-trypsin inhibitor heavy chain H2, transforming growth factor beta 1, follistatin-related protein 1, malate dehydrogenase 1 cytoplasmic, plasma retinol-binding protein, biotinidase, and transferrin, all known to play roles in neural development. Low levels of these proteins suggest that MS/CIS patients suffer from abnormally low oxidative capacity that results in disrupted neural development from an early stage of the disease.

The Secreted Glycoprotein Reelin Suppresses the Proliferation and Regulates the Distribution of Oligodendrocyte Progenitor Cells in the Embryonic Neocortex. J Neurosci 2020; 40:7625-7636. [PMID: 32913108 DOI: 10.1523/jneurosci.0125-20.2020] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Revised: 08/21/2020] [Accepted: 08/31/2020] [Indexed: 11/21/2022] Open
Abstract
Oligodendrocyte (OL) progenitor cells (OPCs) are generated, proliferate, migrate, and differentiate in the developing brain. Although the development of OPCs is prerequisite for normal brain function, the molecular mechanisms regulating their development in the neocortex are not fully understood. Several molecules regulate the tangential distribution of OPCs in the developing neocortex, but the cue molecule(s) that regulate their radial distribution remains unknown. Here, we demonstrate that the secreted glycoprotein Reelin suppresses the proliferation of OPCs and acts as a repellent for their migration in vitro These functions rely on the binding of Reelin to its receptors and on the signal transduction involving the intracellular protein Dab1. In the late embryonic neocortex of mice with attenuated Reelin signaling [i.e., Reelin heterozygote-deficient, Dab1 heterozygote-deficient mutant, or very low-density lipoprotein receptor (VLDLR)-deficient mice], the number of OPCs increased and their distribution shifted toward the superficial layers. In contrast, the number of OPCs decreased and they tended to distribute in the deep layers in the neocortex of mice with abrogated inactivation of Reelin by proteolytic cleavage, namely a disintegrin and metalloproteinase with thrombospondin type 1 motifs 3 (ADAMTS-3)-deficient mice and cleavage-resistant Reelin knock-in mice. Both male and female animals were used. These data indicate that Reelin-Dab1 signaling regulates the proliferation and radial distribution of OPCs in the late embryonic neocortex and that the regulation of Reelin function by its specific proteolysis is required for the normal development of OPCs.SIGNIFICANCE STATEMENT Here, we report that Reelin-Dab1 signaling regulates the proliferation and radial distribution of OPCs in the late embryonic mouse neocortex. Oligodendrocyte (OL) progenitor cells (OPCs) express Reelin signaling molecules and respond to Reelin stimulation. Reelin-Dab1 signaling suppresses the proliferation of OPCs both in vitro and in vivo Reelin repels OPCs in vitro, and the radial distribution of OPCs is altered in mice with either attenuated or augmented Reelin-Dab1 signaling. This is the first report identifying the secreted molecule that plays a role in the radial distribution of OPCs in the late embryonic neocortex. Our results also show that the regulation of Reelin function by its specific proteolysis is important for the normal development of OPCs.
