Abstract

Rho guanine nucleotide exchange factor 9 (ARHGEF9), as a protein that assists small GTPases, is widely present in various tissues. It has been reported to play an important role mainly in neurological diseases and gliomas. However, there have been no reports on its impact on skeletal muscle regeneration after injury. This study first demonstrated a significant increase in ARHGEF9 protein expression during the regeneration of skeletal muscle post-injury in mice. Secondly, during the differentiation of mouse C2C12 myoblasts, ARHGEF9 significantly increased and co-localized with actin filaments. Inhibition of ARHGEF9 significantly downregulated the migration rate and actin filaments polymerization of mouse C2C12 myoblasts, and significantly reduced the expression of proteins related to cell migration. Finally, inhibition of ARHGEF9 significantly reduced the differentiation ability of mouse C2C12 myoblasts. In summary, ARHGEF9 impacting on myoblasts migration and differentiation suggests that targeting ARHGEF9 could be beneficial for promoting skeletal muscle regeneration and repair.

期刊介绍： The Journal of Muscle Research and Cell Motility has as its main aim the publication of original research which bears on either the excitation and contraction of muscle, the analysis of any one of the processes involved therein, the processes underlying contractility and motility of animal and plant cells, the toxicology and pharmacology related to contractility, or the formation, dynamics and turnover of contractile structures in muscle and non-muscle cells. Studies describing the impact of pathogenic mutations in genes encoding components of contractile structures in humans or animals are welcome, provided they offer mechanistic insight into the disease process or the underlying gene function. The policy of the Journal is to encourage any form of novel practical study whatever its specialist interest, as long as it falls within this broad field. Theoretical essays are welcome provided that they are concise and suggest practical ways in which they may be tested. Manuscripts reporting new mutations in known disease genes without validation and mechanistic insight will not be considered. It is the policy of the journal that cells lines, hybridomas and DNA clones should be made available by the developers to any qualified investigator. Submission of a manuscript for publication constitutes an agreement of the authors to abide by this principle.
