Multi-tissue, multi-time-point transcriptomic atlas of aging in mice and rats [mouse]

ABSTRACT: In order to get a greater understanding as to the genes and signaling pathways which are up- or down-regulated in a consistent manner throughout the rodent lifespan, we generated a high N age-related gene expression atlas in mice and rats, by profiling 28 tissues in male and female C57BL/6J mice, and 32 tissues in male Sprague Dawley rats (> 5000 samples) over multiple time points. We identified age-related genes and pathways that change either early in life, at mid-age, late in life, or linearly. Linear genes dominated many but not all tissues, and certain tissues (e.g. gut tissues) were relatively spared from age-related changes. We identified tissues that showed a strong sex bias or species bias. Given the expanse of our transcriptomic dataset, we hope this study will serve as a useful resource for understanding the timing, the tissue-specificity, the gender-specificity, and the species-specificity of age-related gene and pathway changes in male and female mice and male rats.

Watanabe2018_State Transition Model with Treatment and Costs

Project description:Model with functions depending on Age, Male, BP (Blood Pressure). There are 3 disease states: Healthy, Sick, and Dead, where the Dead state is terminal. The yearly transition probabilities are: Healthy to Dead: Age/1000; Healthy to Sick: According to function F1 depending on Age and Male and BP; Sick to Healthy: 0.1; Sick to Dead: according to function F2 depending on Age and Male. Pre-Transition Rules: Age increased by 1 and BP by Age/10 each simulation cycle. Post-Transition Rules: Treatment = BP>140 , becomes 1 when BP crosses 140 threshold; BP =BP-Treatment*10 , meaning a drop of 10 once treatment is applied; CostThisYear = Age + \Treatment*10 , cost depends on age and if treatment was taken; Cost= Cost + CostThisYear , it accumulates cost over time. Initial conditions: Healthy = (50 Male, 50 Female with Age =1,2,...,50 for each individual), BP =120, Sick = (0,0) and Dead = (0,0). Output: Number of men and women in each disease state for years 1-10 and their ages and costs in each state. A stratified report by male and female and young – up to age 30 and old above age 30 is produced.

Project description:Model dependent on changing parameters. There are 3 disease states: Healthy, Sick, and Dead, where the Dead state is terminal. The yearly transition probabilities are: Healthy to Dead: Age/1000; Healthy to Sick: according to function F1 depending on Age and Male parameters; Sick to Healthy: 0.1; Sick to Dead: according to function F2 depending on Age and Male parameters. Pre-Transition Rules: Age increased by 1 each cycle. Initial conditions: Healthy = (50 Male, 50 Female with Age =1,2,…,50 for each individual), Sick = (0,0) and Dead = (0,0). Output: Number of men and women in each disease state for years 1-10 and their ages in each state.

Liver miRNA Expression during the Rat Life Span in both Sexes

Project description:Global miRNA expression was examined in liver tissues from male and female F344 rats over the life span for the purpose of evaluating their possible roles in susceptibility to liver toxicity and disease. Hepatic miRNA expression was characterized at 2, 5, 6, 8, 15, 21, 52, 78, and 104 weeks of age in both sexes using Agilent 8x15k rat miRNA microarrays containing multiple probes for 677 unique miRNAs. Data processing, 75% normalization, and statistical analysis of microarray data were performed in SAS. Functional analysis (Ingenuity) was performed on select miRNAs exhibiting prominent age and sex expression differences. +

FEMALE SEX BIAS AND KINSHIP IN IBERIAN MEGALITHIC SOCIETIES: AN INTERDISCIPLINARY ANALYSIS OF BIOARCHAEOLOGY, aDNA, AND PROTEOMICS

Project description:Uncertainties of traditional osteological methods in biological sex estimation can now be overcome with genomic and proteomic analyses. The combination of the three methodologies has been used for a better understanding of gender-related funerary rituals of the Iberian megalithic cemetery of Panoría. As a result, 44 individuals have been sexed including, for the first time, non-adults. Contrary to the male bias found in many Iberian and European megalithic monuments, the Panoría population shows a clear sex ratio imbalance in favour of females, with twice as many females as males. Furthermore, this imbalance is found regardless of the criterion considered: sex ratio by tomb, chronological period, method of sex estimation or age group. Biological relatedness and kinship have been explored as cultural explanations for this female-related bias. The results obtained for Panoría are indicative of a female-centred social structure, in which sex and/or gender would have influenced funerary rites and cultural traditions.

Mouse multi-organ age-associated protein changes across life stages

Project description:Ageing is a key risk factor for disease and mortality in humans and other animals, with most insights derived from genomic, epigenomic, and transcriptomic studies. However, large-scale datasets on age-related changes at the protein level remain scarce. To fill this gap, we performed a comprehensive quantitative proteomic analysis across eight major organs—brain, heart, lungs, liver, kidneys, spleen, skeletal muscle, and testis—in male C57BL/6J mice, sampled at key life stages: young adult (3–5 months), adult (8 months), mid-life (14 months), and late life (20–26 months). Our results revealed diverse rates of protein expression changes, ranging from rapid (kidneys, spleen) to moderate (liver, lungs) to minimal (skeletal muscle, testis) and subtle (heart, brain). Aging onset appeared earlier in the spleen and kidneys compared to the liver and lungs. By isolating the non-blood proteome, we identified enriched organ-specific processes like oxidative phosphorylation (kidneys) and lipid metabolism (liver), along with shared processes across organs. These findings provide valuable insights into organ-specific and shared protein dynamics underlying age-related diseases.

Role of cGAS-STING pathway in aging and sexual dimorphism in diabetic kindey disease

Project description:We investigated the cGAS-STING inflammatory pathway differential activity among both sexes in T2DN rats and its impact on the temporal progression of the diabetic kidney disease. Here we used both male and female old and young T2DN rats. The cGAS-STING pathway presented distinct protein expression profiles between male and female T2DN rats, which significantly intensify with aging. In male T2DN rats, pro-inflammatory genes are particularly heightened in comparison to female rats of similar age, and such levels are further exacerbated with age. Interestingly, a comprehensive RNA-Seq analysis conducted in the kidney cortex of both sexes of T2DN rats, in younger and older ages, disclosed several central molecules, with crucial genes identified within the cGAS-STING pathway. Our study showed the intricate sexual differences in the development and progression of DKD and proposed the fundamental role of cGAS-STING pathway in disease development.

Reduced IGF-1 signaling fails to limit Alzheimer’s disease progression in a novel rat model of IGF-1R haploinsufficiency

Project description:The growth hormone/insulin-like growth factor-1 (GH/IGF-1) signaling pathway has been strongly implicated in the aging process. Lifespan is profoundly increased in both male and female dwarf mice, while low IGF-1 signaling per se leads to more modest improvements in female lifespan. However, as opposed to the consistency offered by studies in dwarf mice, nuances in the relationship of this axis with health and disease have also been observed, including in rat models of low GH/IGF-1 signaling. This complexity further extends to cognitive decline and Alzheimer’s disease (AD), where this relationship has proven to be nuanced. To help address these gap, we have generated a new rat model of Igf1r+/− haploinsufficiency, to assess effects on metabolic health and AD. Similar to mice, we find that constitutively reduced IGF-1R levels leads to ~15% reduced adult body size in male and female rats, while not impairing insulin sensitivity. However, when crossed with TgF344-AD rats, lowering IGF-1 signaling per se failed to confer protection against AD-related pathology, including amyloid burden, phosphorylated tau or neuroinflammation in male and female TgF344-AD rats, and even appeared to exacerbate facets of disease in females, including an increase in cortical small amyloid plaques. Moreover, a unique hippocampal proteomic signature emerges in female Het/AD rats, including lower levels of proteins involved in redox balance. Overall, these data suggest a nuanced relationship of IGF-1R tone and AD exists and that better defining a more precise role of growth factor signaling in CNS health and disease throughout the life course is warranted.
