在弗雷明汉心脏研究后代队列中,β2 肾上腺素能受体 (ADRB2) 基因的 Gln27Glu 多态性(而非 Arg16Gly 多态性)似乎与多种衰老相关表型相关,包括不同部位的癌症、心肌梗塞 (MI)、间歇性跛行 (IC) 和总体/健康长寿。 Gln27Gln 基因型会增加癌症、MI 和 IC 的风险,而 Glu27 等位基因或等效的 Gly16Glu27 单倍型往往可以预防这些疾病。与长寿的遗传关联在年轻时和高龄时具有相反的性质,突出了拮抗多效性的现象。拮抗性多效性的机制与衍生 Gln27 等位基因携带者在较年轻时的进化驱动优势以及由于癌症、MI 和 IC 风险增加而在老年时的生存劣势有关。 ADRB2 基因在进化背景下的健康衰老过程中发挥着重要的系统性作用,值得在其他人群中进行探索。
The Gln27Glu polymorphism but not the Arg16Gly polymorphism of the beta2-adrenergic receptor (ADRB2) gene appears to be associated with a broad range of aging-associated phenotypes, including cancers at different sites, myocardial infarction (MI), intermittent claudication (IC), and overall/healthy longevity in the Framingham Heart Study Offspring cohort. The Gln27Gln genotype increases risks of cancer, MI and IC, whereas the Glu27 allele or, equivalently, the Gly16Glu27 haplotype tends to be protective against these diseases. Genetic associations with longevity are of opposite nature at young-old and oldest-old ages highlighting the phenomenon of antagonistic pleiotropy. The mechanism of antagonistic pleiotropy is associated with an evolutionary-driven advantage of carriers of a derived Gln27 allele at younger ages and their survival disadvantage at older ages as a result of increased risks of cancer, MI and IC. The ADRB2 gene can play an important systemic role in healthy aging in evolutionary context that warrants exploration in other populations.
