近日,来自美国哈佛医学院的Vadim N. Gladyshev团队在Cell Metabolism上发表了题为:Identification and Application of Gene Expression Signatures Associated with Lifespan Extension的研究成果,研究人员对8种长寿干预的小鼠进行了RNA-seq分析,发现雌性化效应与生长激素调节和雌雄性别相关差异的减少有关。进一步,研究人员将这一分析扩展到17种延长寿命干预措施的公共数据,非常有意思的是,不同种类的干预都会诱导相同的与寿命相关的基因表达变化。不同干预措施都会表现出与延长寿命有关的肝基因特征,包括氧化磷酸化和药物代谢的上调。这些长寿特征的发现可以用来找寻新的延长寿命的干预措施,例如慢性缺氧、KU-0063794和抗坏血酸棕榈酸酯。研究人员还开发了GENtervention,这款app能够可视化基因表达变化与寿命之间的关系。
