Project description:A systematic investigation of aging patterns across virtually all major tissues in non-human primates, our evolutionarily closest relatives, can provide valuable insights into tissue aging in humans, which is still elusive largely due to the difficulty in sampling. Here, we generated and analyzed multi-omics data, including transcriptome, proteome, and metabolome, from 30 tissues of 17 female rhesus macaques (Macaca mulatta) aged 3 to 27 years. We found that certain molecular features, such as increased inflammation, are consistent across tissues and align with findings in mice and humans. We further revealed that tissue aging in macaques is asynchronous and can be classified into two distinct types, with one type exhibiting more pronounced aging degree, likely associated with decreased mRNA translation efficiency, and predominantly contributing to whole-body aging. This work provides a comprehensive molecular landscape of aging in non-human primate tissues and links translation efficiency to tissue-specific aging.
Project description:Splenic tissue was isolated from four adult male Indian-origin Rhesus monkeys serologically positive for non-pathogenic SHIV 89.6 and from matched uninfected four adult male Indian-origin Rhesus monkeys respectively. The corresponding RNA was processed by cDNA microarray analysis. Keywords: SIV infection
Project description:Aging is a major risk factor for various forms of disease. An enhanced understanding of the physiological mechanisms related to aging is urgently needed. Nonhuman primates (NHPs) have the closest genetic relationship to humans, making them an ideal model to explore the complicated aging process. Multiomics analysis of NHP peripheral blood offers a promising approach to evaluate new therapies and biomarkers. Here, we explored the mechanisms of aging using proteomics (serum and serum-derived exosomes [SDEs]) in rhesus monkey (Macaca mulatta) blood.
