title: MicroRNA: Key regulators of oligodendrocyte development and pathobiology.
abstract: MicroRNAs (miRNAs or miRs) are a group of small non-coding RNAs that function through binding to messenger RNA (mRNA) targets and downregulating gene expression. miRNAs have been shown to regulate many cellular functions including proliferation, differentiation, development and apoptosis. Recently, evidence has grown which shows the involvement of miRs in oligodendrocyte (OL) specification and development. In particular, miRs-138, -219, -338, and -9 have been classified as key regulators of OL development, acting at various points in the OL lineage and influencing precursor cell transit into mature myelinating OLs. Many studies have emerged which link miRNAs with OL and myelin pathology in various central nervous system (CNS) diseases including multiple sclerosis (MS), ischemic stroke, spinal cord injury, and adult-onset autosomal dominant leukodystrophy (ADLD).
