Outline of Final Research Achievements

In rheumatoid arthritis, epigenetic regulatory mechanisms in synovial cells are largely unknown. We have tried to explore epigenetic regulator and its molecular functions that contribute to the progression of rheumatoid arthritis. We found that epigenetic regulator Uhrf1 was significantly increased in arthritis tissue and expressed in synovial fibroblasts. In addition, our results indicated that Uhrf1 in synovial fibroblasts suppressed expressions of cytokines-related genes and regulated arthritis progression negatively.

Academic Significance and Societal Importance of the Research Achievements

現在、関節リウマチ治療において生物学的製剤が奏功しているが、これらは単一の増悪因子に対する阻害剤であり、十分な効果が認められないケースも報告されている。これまでの研究成果より、滑膜線維芽細胞に発現するUhrf1はいくつかの関節リウマチ増悪因子の発現を網羅的に制御している可能性が示唆されている。関節リウマチ患者の滑膜線維芽細胞でUhrf1発現を上昇させる、あるいは安定化させることができれば、既存の治療薬よりも高い効果が得られるかもしれない。
