Caloric restriction (CR) slows biological aging and prolongs healthy lifespan in model organisms. Findings from CALERIE-2 - the first ever randomized, controlled trial of long-term CR in healthy, non-obese humans - broadly supports a similar pattern of effects in humans. To expand our understanding of the molecular pathways and biological processes underpinning CR effects in humans, we generated a series of genomic datasets from stored biospecimens collected from n=218 participants during the trial. These data constitute the first publicly-accessible genomic data resource for a randomized controlled trial of an intervention targeting the biology of aging. Datasets include whole-genome SNP genotypes, and three-timepoint-longitudinal DNA methylation, mRNA, and small RNA datasets generated from blood, skeletal muscle, and adipose tissue samples (total sample n=2327). The CALERIE Genomic Data Resource described in this article is available from the Aging Research Biobank. This mult-itissue, multi-omic, longitudinal data resource has great potential to advance translational geroscience.
热量限制(CR)可减缓模式生物的生物衰老并延长健康寿命。CALERIE-2(有史以来第一项针对健康、非肥胖人群的长期CR随机对照试验)的研究结果广泛支持了人类中类似的效应模式。为了扩展我们对CR在人类中的作用所涉及的分子途径和生物过程的理解,我们从试验期间收集的n = 218名参与者的储存生物样本中生成了一系列基因组数据集。这些数据构成了首个针对衰老生物学干预的随机对照试验的公开可用基因组数据资源。数据集包括全基因组SNP基因型,以及从血液、骨骼肌和脂肪组织样本中生成的三个时间点的纵向DNA甲基化、mRNA和小RNA数据集(总样本n = 2327)。本文所述的CALERIE基因组数据资源可从衰老研究生物样本库获取。这个多组织、多组学的纵向数据资源在推进转化老年科学方面具有巨大潜力。
