Research Abstract |
The aim of this study is to develop a new treatment in orthodontics by focusing on clock genes which are regulated by microRNAs. Then we investigated osteoclasts, which play an important role in orthodontics. Specifically, we investigated eight miRNAs deemed important for osteoclastogenesis in our study: let-7e, miR-21, miR-33, miR-155, miR-210, miR-223, miR-378, and miR-1224. The results suggest that osteoclasts secrete extracellular microvesicles containing specific miRNAs, but that they do not contain the entire set of intracellular miRNAs.
