Non-coding RNAs(ncRNAs) are a large cluster of RNAs that do not encode proteins,but have multiple functions in diverse cellular processes.Mounting evidence indicates the involvement of nc RNAs in the physiology and pathophysiology of the central and peripheral nervous systems.It has been shown that numerous ncRNAs,especially micro RNAs and long non-coding RNAs,are differentially expressed after insults such as acquired brain injury,spinal cord injury,and peripheral nerve injury.These ncRNAs affect neuronal survival,neurite regrowth,and glial phenotype primarily by targeting specific mRNAs,resulting in translation repression or degradation of the mRNAs.An increasing number of studies have investigated the regulatory roles of micro RNAs and long non-coding RNAs in neural injury and regeneration,and thus a new research field is emerging.In this review,we highlight current progress in the field in an attempt to provide further insight into post-transcriptional changes occurring after neural injury,and to facilitate the potential use of ncRNAs for improving neural regeneration.We also suggest potential directions for future studies.
