Outline of Final Research Achievements

We clarified that several enzymes involved in epigenetics are targets of nitric oxide (NO). We found that the enzymatic activity was significantly inhibited by modification of Cys residue. In addition, we screened the genes whose expression levels were changed by NO exposure with RNA-seq analysis. From this screening, we succeeded in isolating many candidate genes. Then, we attempted to isolate the compound that attenuates the modification from in silico screening. A compound could inhibit S-nitrosylation of target protein in a concentration-dependent manner. Furthermore, this chemical significantly attenuated the gene expression in response to NO.
Our findings strongly suggested that NO is a key factor that regulates gene expression via dysfunction of epigenetic system.

Academic Significance and Societal Importance of the Research Achievements

本研究は生体内で産生されるガス状分子である一酸化窒素(NO)の遺伝子発現に対する影響を調べたものである.一酸化窒素は,血圧調節や記憶形成など様々な役割を担っている.この研究で,NOがある酵素に結合・修飾することで活性を低下させ,ゲノム修飾を抑制して遺伝子発現を誘導することが明らかとなった.さらに,この修飾を特異的に阻害する化合物の単離に成功した.この化合物はNOによる遺伝子発現を顕著に抑制することが確認された.また,NOによって形成されるがんに有効であった.従って,がんや神経変性疾患の中,ある種のものはNOが原因であり,本研究で開発された化合物は強力なツールであることが示唆された.
