miRNA dysregulation links EBV infection and vitamin D

Integrational analysis of miRNAs data sets as a plausible missing linker between Epstein-Barr virus and vitamin D in relapsing remitting MS patients

Given the multifactorial state of autoimmune complex diseases such as multiple sclerosis (MS), it is not clear if different risk factors act jointly or independently. Despite intensive studies investigating multi aspects of MS risk factors, findings with regards to potential biomarkers that may link these risk factors remained largely inconclusive.

System biology or data integration utilizes different validated datasets to extract meaningful information and map the plausible biological pathways and networks. As such, we integrated eight transcriptome datasets to find the differentially expressed miRNAs in peripheral blood (PB) between relapsing remitting MS patients (RRMS) and normal group. After identification the targeted genes of miRNAs, the hub genes were used to construct the underlying protein–protein interaction network and signaling pathways.

As results, 9 miRNAs were best exemplified by significant dysregulation including hsa-mir-15a, hsa-mir-484, hsa-mir-30d, hsa-mir-145, hsa-mir-363, has-let-7e, hsa-mir-30a, hsa-let-7b, and hsa-mir-146a. System biology analysis of miRNAs in PB of RRMS patients clearly indicates the involvement of miRNAs in many vital pathways and highlighted the possibility of an association between miRNAs with EBV and vitamin D in MS pathogenesis.

Described novel pathways and genes related to miRNAs such as Transient receptor potential channels and Acid sphingomyelinase may provide a potential target for therapeutic approaches although further functional studies are warranted to test these candidates.
