Outline of Final Research Achievements |
It is reported that Salmonella shift to a nonproliferative state in response to antimicrobial drug administration to enhance antimicrobial resistance. In this research, we focused on the drug-responsive gene regulatory network to elucidate the mechanism of Salmonella transition to the nonproliferative state in response to antimicrobial drug. As part of the gene regulatory network analysis, we developed a method for simultaneous measurement of transcription and degradation of intracellular RNAs comprehensively under specific environmental conditions. At the same time, we developed a method to search for functional RNA sequences that regulate the stability of intracellular RNAs. These results have already been published.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、サルモネラ菌の薬剤耐性移行メカニズムを遺伝子制御ネットワークの観点から解明するものである。またその過程として、(1) 細胞内RNAのダイナミクスを網羅的に解明するDyrec-seq、(2) 細胞内RNAの安定性を人為的に制御する配列を探索するFate-seqを開発した。これらの研究成果は、感染症の予防や対策における意義を有するのはもちろんであるが、同時に他の細胞の状態変化原理の解明・制御に対しても重要な視点を与えるものである。
