Outline of Final Research Achievements |
Small RNA-seq and bioinformatic method showed that miR-15b-5p regulates expression of muscarinic receptor 3 (CHRM3), and that regulation of CHRM3 by miR-15b-5p can inhibit activation of YAP signaling induced by CHRM3. microRNA-15b-5p/m3/YAP signaling axis is a novel pathway which promotes castration-resistant growth of PCa. Our findings provide novel mechanisms of muscarinic-signal-driven CRPC progression.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果により、miR-15b-5p/CHRM3/YAPシグナルの活性化が前立腺癌の去勢抵抗性増殖の機序の一因と考えられた。前立腺癌の神経依存的な去勢抵抗性増殖がこれまで報告されているが、その原因として、機能性RNAによるムスカリン受容体の遺伝子発現変化が示された。本研究成果は、前立腺癌のアンドロゲン受容体に依存しない去勢抵抗性増殖の機序の解明の一助となりうると考えられた。
