MicroRNAs and Fracture Healing.

Calcif Tissue Int; 101(4): 355-361, 2017 10.
Artigo em Inglês | MEDLINE | ID: mdl-28589206
MicroRNAs (miRNAs) are small molecules found to have major regulatory roles in many biological processes. This review aims to provide an overview of the recent advances in knowledge of the role of miRNAs in fracture healing and bone repair. A search of the published literature was performed (using the PubMed database) to include all relevant studies published in English. These studies were then reviewed and the results condensed into this review paper. MiRNAs have now been shown to have significant alterations in expression levels in bone tissue in the presence of fractures. This is thought to be related to the process of fracture healing through effects on osteoblasts and bone growth factors. These small molecules are also detectable in the circulation where their expression appears to be altered by the presence of fractures. Although further research is required in this area, miRNAs may present an opportunity for future clinical applications in fracture management.
