Outline of Final Research Achievements

For the students with suicide high-risk and non-suicidal healthy students, gDNA from peripheral blood, MWAS-based telomere length by using Infinium Human Methylation 450K BeadChip, suicide-attempt history, and various suicide-related clinical scales such as HAMD17, SRS18 and C-SSRS were obtained. We found shorter MWAS-based telomeres in young suicidal subjects compared to the healthy group. We also identified the association between suicide risk in women after middle age and rs12415800 related to SIRT1 gene which is well-known to be related to telomere dynamics.

Academic Significance and Societal Importance of the Research Achievements

コロナ禍の影響などもあって、大学生の自殺を含む若年者自殺の現状はより深刻化しており、若年自殺リスクの客観的な生物学的指標の知見獲得が強く望まれている。申請者らは本研究の対象者を含む若年自殺行動者群において、MWASデータ由来の末梢血テロメア長が健常群に比して有意に短縮しているという知見を得ており、今後さらなる学生のサンプルサイズ増加により知見確立に挑む。本成果はInfinium Human Methylation 450K BeadChipという市販のアレイ(世界共通のプラットフォーム)での知見のため、将来的な臨床応用に非常に有利であると考える。
