“…While genetic studies have identified genes critical to the immune system as being potential risk factors (Baranzini et al, 2009b;De Jager et al, 2009;Beecham et al, 2013), many of the genetic contributors to this disease are unknown. An emerging area of interest in multiple sclerosis has been genetic regulation at the microRNA (miRNA) level (Du et al, 2009;Keller et al, 2009;Otaegui et al, 2009;De Santis et al, 2010;Guerau-de-Arellano et al, 2011;Noorbakhsh et al, 2011;Jr OeF et al, 2012;Smith et al, 2012;Gandhi et al, 2013;Ridolfi et al, 2013;Søndergaard et al, 2013). MiRNAs are small, non-coding RNA that regulate gene expression and, thus, modify cellular pathways and disease processes (Ambros, 2004;Bartel, 2004).…”
