This balance appears to be a key mechanistic link connecting RA immune dysregulation and bone metabolism imbalance. Agents targeting this balance (such as EZH2 inhibitors and Janus kinase [JAK] inhibitors) have shown promising preclinical potential for dual anti\u2010inflammatory and bone\u2010protective effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The dynamic balance of histone H3 methylation emerges as a potential core regulatory hub in the pathological process of RA based on preclinical studies, providing theoretical support for precise diagnosis and treatment of RA.
