MiRNA expression data from rhesus macaque postnatal brain in prefrontal cortex: time course

ABSTRACT: Gene expression changes determine functional differentiation during development and are associated with functional decline during aging. While developmental changes are tightly regulated, regulation of aging changes is not well established. To assess the regulatory basis of age-related changes and investigate the mechanism of regulatory transition between development and aging, we measured mRNA and microRNA expression patterns in brains of humans and rhesus macaques over the entire species’ lifespan. We find that in both species, developmental and aging changes overlap in the course of lifetime with many changes found at the late age initiating in early childhood.

While developmental changes are tightly regulated, regulation of aging changes is not well established. To assess the regulatory basis of age-related changes and investigate the mechanism of regulatory transition between development and aging, we measured mRNA and microRNA expression patterns in brains (superior frontal gyrus) of humans and rhesus macaques over the entire speciesâ lifespan. We find that in both species, developmental and aging changes overlap in the course of lifetime with many changes found at the late age initiating in early childhood. Human post-mortem brain samples from the superior frontal gyrus region of the prefrontal cortex were collected. The age ranges of the indibiual in human covered its whole life span fom newborn to death. RNA extracted from the dissected tissue was hybridized to AffymetrixÂ® Human Gene 1.0 ST arrays.

Age associated differences in microbiome in Rhesus Macaque

Project description:Aging is associated with declining immunity and inflammation as well as alterations in the gut microbiome with a decrease of beneficial microbes and increase in pathogenic ones. The aim of this study was to investigate aging associated gut microbiome in relation to immunologic and metabolic profile in a non-human primate (NHP) model. 12 old (age>18 years) and 4 young (age 3-6 years) Rhesus macaques were included in this study. Immune cell subsets were characterized in PBMC by flow cytometry and plasma cytokines levels were determined by bead based multiplex cytokine analysis. Stool samples were collected by ileal loop and investigated for microbiome analysis by shotgun metagenomics. Serum, gut microbial lysate and microbe-free fecal extract were subjected to metabolomic analysis by mass-spectrometry. Our results showed that the old animals exhibited higher inflammatory biomarkers in plasma and lower CD4 T cells with altered distribution of naïve and memory T cell maturation subsets. The gut microbiome in old animals had higher abundance of Archaeal and Proteobacterial species and lower Firmicutes than the young. Significant enrichment of metabolites that contribute to inflammatory and cytotoxic pathways was observed in serum and feces of old animals compared to the young. We conclude that aging NHP undergo immunosenescence and age associated alterations in the gut microbiome that has a distinct metabolic profile.

miRNA expression data from rhesus macaque testes: time course

Project description:Small RNA including microRNA (miRNA) and Piwi-interacting RNA (piRNA) play important roles in germline maintenance and maturation in wide variety of species. Relatively little however is known about role played by miRNA in male germline maturation in humans and closely related primate species. Here we focused on rhesus macaques as a model species closely related to humans to study small RNA expression in testis samples throughout postnatal development and maturation. We observe clear transition in miRNA and piRNA expression resulting in the overall increase of piRNA expression levels and corresponding decrease in miRNA expression. Unexpectedly, this transition takes place at approximately one year of age – far earlier then rhesus macaque sexual maturation occurring at 4-5 years of age. Notably, contradictory to the overall trend of expression decline, a group of 29 miRNA showed marked expression increase in macaque testis at approximately five years of age – the time interval associated with sexual maturation. Keywords: miRNA piRNA Age Series

Annotation and functional clustering of circRNA expression in rhesus macaque brain during aging

Project description:The abundance and function of circular RNAs (circRNAs) in mammalian brain have been reported, but their alterations in the biology of brain aging remain elusive. Here, using deep RNA profiling with linear RNA digestion by RNase R we explored a comprehensive map of changes in circRNA expression in rhesus macaque (macaca mulatta) brain in two age groups from adult (10 y) to aged (20 y) periods. Total 17,050 well expressed, stable circRNAs were identified. Cluster analysis reveals that dynamic changes in circRNA expression show the spatial-, sex- and age-biased specificities. On the basis of separate profiling of the RNAs, age-related circRNAs show differential correlation to host mRNA expression. Furthermore, two voltage-dependent L- and R-type calcium channel gene-derived circCACNA2D1 and circCACNA1E negatively regulate their host mRNA expression. Our results demonstrate the power of changes in circRNA expression to reveal insights into a potentially circRNA-mediated regulatory mechanism underlying the biology of brain aging.

Quantitative protein profiling of brain vessels in rhesus macaque

Project description:Aging is a major risk factor for cerebrovascular disease. However, the molecular mechanisms of cerebrovascular aging remain to be clarified. In this study, we performed proteomics analysis aimed to reveal the molecular signaling pathways during aging.our study demonstrated that the imbalance of vasodilators and vasoconstrictors caused by downregulation of NOS3, oxidative stress mediated by the suppression of NRF2 pathway, and miRNA-regulated accumulation of ECM proteins were critical for cerebrovascular aging.
