Outline of Final Research Achievements

We newly found a role of histone acetyltransferases CBP and p300 in rheumatoid arthritis (RA) as follows. In vitro assay using RA-fibroblast like synovial cells, (1) TNF-α, a pro-inflammatory cytokine, induced core clock gene Bmal1 through up-regulating Cbp and p300 gene expression. (2) This induction is cancelled by C646, p300/CBP inhibitor. (3) As well as Bmal1, expression of CCL2 gene,a pro-inflammatory chemokine, is suppressed by C646. In vivo assay using collagen-induced arthritis (CIA) mice, (4) C646-treated mice decreased a arthritis score as compared with DMSO-treated one.

Academic Significance and Societal Importance of the Research Achievements

本研究は関節リウマチ患者由来滑膜繊維芽細胞において、TNF-αによる時計遺伝子発現パターンの変調にはヒストンアセチル化酵素が関与している、ことを示した初めての知見である。ヒストンアセチル化酵素阻害薬であるC646は、滑膜細胞の遊走を抑制し関節炎モデルマウスの重症化を抑制させる効果を認めた。これらのことから、ヒストンアセチル化酵素は関節炎の悪化を時計遺伝子を介して軽減することができる可能性が示され、RAの新しい治療標的となることが期待される。
