Precise regulation of Egr2 transcription is fundamentally important to the control of peripheral myelination. Here we describe a long non-coding RNA antisense to the promoter of Egr2 (Egr2-AS-RNA). During peripheral nerve injury, the expression of Egr2-AS-RNA is increased and correlates with decreased Egr2 transcript and protein levels. Ectopic expression of the Egr2-AS-RNA in DRG cultures inhibits the expression of Egr2 mRNA and induces demyelination. In vivo inhibition of the Egr2-AS-RNA using oligonucleotide GapMers released from a biodegradable hydrogel following sciatic nerve injury reverts the EGR2-mediated gene-expression profile and significantly delays demyelination. The Egr2-AS-RNA gradually recruits H3K27ME3, AGO1, AGO2 and EZH2 on the Egr2 promoter following sciatic nerve injury. Furthermore, expression of the Egr2-AS-RNA is regulated through ERK1/2 signaling to YY1, while loss of Ser184 of YY1 regulates binding to the Egr2-AS-RNA. In conclusion, we describe functional exploration of an antisense long non-coding RNA in PNS biology. Martinez-Moreno et al., report a role for a long non-coding RNA antisense to the promoter of Egr2-AS-RNA, during the response to peripheral nerve injury. Inhibition of the Egr2-AS-RNA following sciatic nerve injury reverts EGR2-mediated gene expression and delays demyelination.
