Human Study on miRNA Expression Patterns and Multiple Sclerosis Outcomes
A study involving 54 MS patients found that dysregulation of specific microRNAs (miR-10a, miR-146a, miR-155) was significantly associated with clinical outcomes like disability scores and the appearance of cervical spinal cord lesions over roughly five years.

Why it matters
These findings suggest that miRNAs could be valuable as biomarkers for monitoring disease progression in MS, pointing to possible pathways for further research.
What this does not prove
The study's associations are hypothesis-generating and need further validation in larger, prospective studies that include ongoing miRNA assessment.

primary endpointBetween 2015 and 2018, expression levels of miR-10a, miR-146a, and miR-155 were obtained from whole blood samples of patients with MS using RT-PCR and evaluated to investigate associations between baseline miRNA expression patterns and subsequent clinical and radiological outcomes.
follow upFollowing expression analysis, the number of relapses, annualized relapse rate, changes in Expanded Disability Status Scale (EDSS) score, radiological activity, and achievement of No Evidence of Disease Activity (NEDA-3) status were assessed over a mean follow-up period of approximately 5 years.
findingsmiR-10a dysregulation was significantly associated with the final EDSS score (P = .007) and the presence of cervical spinal cord lesions at baseline (P = .040).
findingsmiR-10a dysregulation was significantly associated with the final EDSS score (P = .007) and the presence of cervical spinal cord lesions at baseline (P = .040).
findingsmiR-146a and miR-155 dysregulation were significantly associated with the development of new cervical spinal cord lesions (P = .020 and P = .025, respectively).
findingsmiR-146a and miR-155 dysregulation were significantly associated with the development of new cervical spinal cord lesions (P = .020 and P = .025, respectively).
findingsmiR-155 also showed a nominal association with overall radiological activity (P = .049).
limitationsThese findings should be considered hypothesis-generating and require confirmation in larger prospective studies with longitudinal miRNA assessment and independent validation.
biological targetsAssociations were observed between miR-10a and disability measures, between miR-146a/miR-155 and new cervical spinal cord lesions, and between miR-155 and radiological activity.
