摘要:DNA variants that modulate life span provide insight into determinants of health, disease, and aging. Through analyses in the UM-HET3 mice of the Interventions Testing Program (ITP), we detected a sex-independent quantitative trait locus (QTL) on chromosome 12 and identified sex-specific QTLs, some of which we detected only in older mice. Similar relations between life history and longevity were uncovered in mice and humans, underscoring the importance of early access to nutrients and early growth. We identified common age- and sex-specific genetic effects on gene expression that we integrated with model organism and human data to create a hypothesis-building interactive resource of prioritized longevity and body weight genes. Finally, we validated Hipk1, Ddost, Hspg2, Fgd6, and Pdk1 as conserved longevity genes using Caenorhabditis elegans life-span experiments.
为了突破这一局限,此次的新研究引人注目地对3200多只小鼠进行了基因分型。“在识别寿命基因的同类研究中,是小鼠数量最多的一项研究。”作者之一James F. Nelson博士指出。不仅数量多,更重要的是,这些小鼠有非常多样化的遗传背景。不同品系的小鼠在同一个基因位点可能有不同的变异版本,导致产生的蛋白略有不同。而随着年龄的增长,即便是细微的差别也可能导致不同的健康结果。这种多样性“模拟了人类群体的遗传多样性”。
