Long non-coding RNA and wound healing

Long non-coding RNA (lncRNA) is a class of RNA molecules longer than 200 nucleotides which does not encode proteins or only encode a few proteins, and it plays important regulatory roles in the expression of genes at the epigenetic, transcriptional, and posttranscriptional levels. The recent reports suggest that lncRNA plays a significant role in growth and development of body, cellular biological processes including in cell proliferation, differentiation, migration, and apoptosis, and regulation of wound healing processes such as re-epithelialization, angiogenesis, and scar formation. The lncRNA has become a new research hotspot in wound healing. This article reviews the role of lncRNA in different stages of wound repair to get a further understanding of molecular mechanisms of wound healing and provide a new target spot for prevention and treatment of pathological scars and wound healing.
