Outline of Research at the Start

父親の高齢化は様々な精神・発達障害のリスクとして知られています。本研究では、精子に高発現する非コードRNA*1に注目して、加齢に伴う非コードRNAの発現パターン変化を解析し、父親の高齢化に伴う精神・発達障害の分子病態としての非コードRNAの同定を目指す。さらに、標的となる非コードRNAを制御することにより、父親の高齢化に伴う精神・発達障害の治療法の開発を試みる。
*1: タンパク質をコードしないRNA

Outline of Final Research Achievements

In the present study, we found abnormal vocal communication during early postnatal in pup derived from aged father, compared to that derived from young father in C57BL/6J mice. To uncover the underlying molecular mechanisms, we planned research focusing on non-coding RNA in sperm, but could not be successfully implemented collaboration. In contrast, whole-genome target methylome analyses using sperm DNA and comprehensive gene expression analysis using developing forebrain identified enrichment of REST/NRSF (neuron-restrictive silencer factor) target genes. Taken together, REST/NRSF is suggested to be a key molecule in understanding the molecular neuropathology of mental and developmental disorders in children born to aged fathers.

Academic Significance and Societal Importance of the Research Achievements

私たちの発見は、父親の高齢化が子どもの精神疾患や発達障害のリスクを増大させるメカニズムとして、精子の加齢が、これまでの無秩序な複製エラーだけではなく、神経分化制御因子REST/NRSFを介した生物学的基盤により制御されていることを示唆するものである。このことはすなわち、将来的にREST/NRSFを分子標的として、加齢精子の予防法および治療法、診断方法の開発につながる可能性が期待できる。
