Loss of motoneuron-specific microRNA-218 causes systemic neuromuscular failure [miRNA-seq]

ABSTRACT: We investigated microRNA expression in motoneurons by performing small RNA sequencing of fluorescence-activated cell sorting (FACS)-isolated motoneurons labelled with the Hb9:gfp transgenic reporter and Hb9:gfp negative non-motoneurons including spinal interneurons. We find that one microRNA, microRNA-218, is highly enriched and abundantly expressed in motoneurons. Furthermore, we find that miR-218 is transcribed from alternative, motoneuron-specific alternative promoters embedded within the Slit2 and Slit3 genes by performing RNA sequencing of FACS-isolated motoneurons and a dissected embryonic floor plate cells which served as a control. Next, we performed RNA sequencing of FACS-isolated wild type (WT) motoneurons and motoneurons lacking miR-218 expression (218DKO motoneurons), and fi
