We applied various analytical tools to identify genes with consistent expression changes in multiple individuals in response to Gua Sha and their networks.Results We found that while the changes were very subtle and individual-specific, we could identify consistent upregulation of three histone genes. Further analysis of the potential regulatory networks of these histone genes revealed the enrichment of functions involved in the immune response and inflammation.Conclusion The significance of these results in the context of potential effects of Gua Sha and the next steps in exploring the molecular mechanisms of action of this technique are discussed.展开更多
