Outline of Final Research Achievements

MicroRNAs are deeply involved in the pathogenesis of rheumatoid arthritis. We are interested in miR-124.3p, which is a specifically decreased miRNA in the synovium of rheumatoid arthritis patients. We discovered MCP1, a inflammatory cytokine, and CDK2, a cell cycle regulator, as the specific target mRNAs of miR-24.3p before. In this study, we newly discovered MAPK14 and RANKL as target mRNAs of miR-124.3p using Luciferase reporter assay.

Academic Significance and Societal Importance of the Research Achievements

われわれは、関節リウマチの滑膜細胞にて特異的に発現低下しているmiR-124.3pに注目してきた。これまでに、ケモカインであるMCP1や細胞周期制御因子のCDK2のmRNA発現がmiR-124.3pにて抑制されるため、ケモカインや細胞周期を制御することにより関節リウマチの病態に抑制的に働くことを明らかにしてきたが、今回MAPK14がmiR-124.3pの標的分子であることが明らかとなり、miR-124.3pの多彩な生理学的活性の存在を示した。miR-124.3pの関節リウマチの治療薬としての可能性がさらに高まった。
