BackgroundDemyelination and failure of remyelination are core mechanisms in the pathogenesis of multiple sclerosis MS; the factors modulating these processes are still mostly unknown. MicroRNA 572 miR-572 is deregulated in MS and is suggested to targets neural cell adhesion molecule NCAM, a glycoprotein involved in CNS reparative mechanisms. The aim of this study is to analyze miR-572 in patients with different clinical phenotypes of MS.

MethodsqPCR quantification of miR-572 isolated from serum was performed in 16 primary progressive PP, 15 secondary progressive SP, 31 relapsing remitting RR MS patients and 15 sex-and age-matched healthy controls.

ResultsmiR-572 expression was reduced overall in MS patients p < 0.05 compared to HC; this miRNA was significantly upregulated in SPMS and in RRMS during disease relapse, whereas it was downregulated in PPMS and in quiescent phases of RRMS. miR-572 expression correlated with EDSS scores RSp = 0.491; p < 0.05 independently of the clinical phenotype. The results suggest that this miRNA might be a tool that helps distinguishing between PPMS and SPMS and between relapsing and remitting phases in RRMS.

ConclusionsEvaluation of miR-572 may serve as a non-invasive biomarker for remyelination.
