During peripheral nervous system development, successful communication between axons and glial cells including Schwann cells in peripheral nervous system and oligodendrocytes in central nervous system, is required for the proper functions of both neurons and glia. Three types of alternatively-spliced proteins belonging to the neuregulin1 (NRG1) gene family of growth and differentiation factors are essential for Schwann cell survival and peripheral nerve development. While membrane-bound NRG1 forms (type III) has been strongly implicated in the regulation of myelination process at late stage of Schwann cell development, little is known about the role of soluble, heparin-binding forms of NRG1 (type I/II) …

roX1 is a long non-coding RNA involved in the chromosome-wide gene regulation that occurs during dosage compensation in Drosophila. Dosage compensation in Drosophila melanogaster occurs by a global two-fold increase of transcription from the single male X chromosome. This essential process compensates for X chromosome monosomy. The male-specific lethal (MSL) complex, containing five proteins, localizes to the male X chromosome and alters chromatin to modify gene expression. roX1 and roX2 RNAs are redundant components of MSL complex that are required for its exclusive X-localization. Recent studies in our lab have revealed a second role of roX RNAs in heterochromatic gene …
