2020 Fiscal Year Research-status Report

The effects of genetic factors on skeletal muscle and joint functions before and after eccentric contractions

Research Project

Project/Area Number 17KK0073
Research InstitutionHosei University

Principal Investigator

越智 英輔  法政大学, 生命科学部, 准教授 (90468778)

Project Period (FY) 2018 – 2021
Keywords筋損傷 / 遺伝子改変 / サテライト細胞 / 遺伝子多型 / 筋再生
Outline of Annual Research Achievements

本年度は、昨年度実施した筋サンプルを用いて分析を行った。サンプルは筋サテライト細胞特異的Jmjd3欠損マウスとwild typeを対象とし、筋損傷を誘発した前脛骨筋とした。筋損傷7日後、21日後のタイムポイントで分析した結果、筋線維横断面積は筋損傷7日後において両群ともに損傷によって有意に低下した。しかしながら筋損傷21日後では、サテライト細胞特異的Jmjd3欠損マウスのみにおいて低下していた。さらに、pax7陽性細胞数は、筋損傷7日後においてwild typeのみで増加した一方、サテライト細胞特異的Jmjd3欠損マウスは変化しなかった。この結果は、筋損傷21日後でも同様であった。今後はmRNA解析を進める。
