Transcriptome analysis of metabolic tissues in young and aged mice

ABSTRACT: Studies on aging have largely included one or two OMICS layers, which may not necessarily reflect the signatures of other layers. Moreover, most aging studies have often compared very young (4-5 wks) mice with old (24 months) mice which does not reflect the aging transition after the attainment of adulthood. Therefore, we aimed to study and compared muti-OMICS aging signatures across key metabolic tissues of mature adults (6 months) and old (24 months) C57BL/6J mice (the most commonly used mouse strain). We compared the differentially regulated genes and enriched pathways for transcriptome, proteome and epigenome (H3K27ac, H3K4me3, H3K27me3, DNA methylation) across different tissues. Here are transcriptome data from Affymatrix microarrays.

Multi-Omics Analyses Revealed Conserved Aging Signatures in Mice

Project description:Studies on aging have largely included one or two OMICS layers, which may not necessarily reflect the signatures of other layers. Moreover, most aging studies have often compared very young (4-5 wks) mice with old (24 months) mice which does not reflect the aging transition after the attainment of adulthood. Therefore, we aimed to study and compared muti-OMICS aging signatures across key metabolic tissues of mature adults (6 months) and old (24 months) C57BL/6J mice (the most commonly used mouse strain). Here we compared the differentially regulated genes and enriched pathways for transcriptome, proteome and epigenome (H3K27ac, H3K4me3, H3K27me3, DNA methylation) across liver, heart, and quadriceps muscle. The major aging associated pathways cross multiple layers and tissues are decreased RNA metabolism, transcription, and translation at transcript and protein levels however increased potential of transcription at DNA methylation and H3K27ac levels.

An aging-like phenotype occurs in Tif1γ-/- hematopoietic stem cells

Project description:To determine whether an accelerated aging-like phenotype occurs in hematopoiesis of young Tif1γ-/- mice (4 months old), we purified 200,000 hematopoietic stem cells (LSK: Lineage negative, Sca1+, c-Kit+) from Tif1γ-/- mice and performed high-throughput mRNA sequencing (RNA-seq). We compared this transcriptome to physiological aging by creating two other RNAseq libraries from young (4 months old) and old (20 months old) wild type mice.

Project description:Immune system aging contributes significantly to declining health with age. It is unknown to what extent human and mice immune systems go through similar age-related changes and whether there are conserved biomarkers of aging. We characterized age-related changes in the immune system of long (C57BL/6J) and short-lived (NZO/HILtJ) strains and compared them with blood-driven human aging signatures. Peripheral blood lymphocytes (PBL), spleen cells and spleen-driven naive and memory CD8+ T cells were profiled using flow cytometry, RNA-seq and ATAC-seq from young (3 months) and old (18 months) mice. Pro-inflammatory myeloid genes were activated with age across strains and tissues, echoing human 'inflammaging' signatures. ATAC-seq footprinting analyses uncovered increased binding of pro-inflammatory transcription factors with age (e.g., AP1 complex, NFKB signaling pathway). Machine learning models identified inflammation, cytotoxic, and naive T cell derived genes to be strong signatures of immunosenescence. These data are publicly shared as a resource for immune aging (https://immune-aging.jax.org/mice).

Bleomycin model of fibrosis and resolution phase in old and young mice

Project description:Bleomycin-induced pulmonary fibrosis in mice mimics major hallmarks of idiopathic pulmonary fibrosis, yet in this model it spontaneously resolves over time. We studied molecular mechanisms of fibrosis resolution and lung repair, focusing on transcriptional and proteomic signatures and the effect of aging. Young (3 months) and old (21 months) mice were treated with Bleomycin or with control saline solution and analyzed transcript and protein expression over 8 weeks (Day 0, 14, 21, 28, 35, 42, 49, 56).

Decoupling of mRNA and protein expression in aging brains reveals the age-dependent adaptation of specific gene subsets

Project description:To investigate the connection between changes of mRNA and protein expression in the brain during aging, we compared the transcriptome and proteome of the mouse cortex. We profiled gene expression in the mouse cortex using data obtained from RNA-seq of three individuals at 6-months old and three individuals at 24-months old.

Interferon Regulatory Factor 7 (IRF7) in aging of adipose-derived mesenchymal stromal cells

Project description:We found that Interferon Regulatory Factor 7 (IRF7) is upregulated in adipose-derived stromal cells (MSC) of 12 months-old (middle-age) mice compared with 1 month-old mice. To go in depth into the role of IRF7 in aging of MSC we knocked-down it in 12 months MSC and assessed the transcriptional changes though whole-genome microarray analysis. We investigated the transcriptional changes induced by the Interferon Regulatory Factor 7 (IRF7) knock-down in mesenchymal stromal cells established from the inguinal fat pad of 12-months-old mice.

Age-mediated transcriptomic changes in adult mouse substantia nigra

Project description:Substantia nigra pars compacta (SNpc) is highly sensitive to normal aging and selectively degenerates in Parkinson's disease. Until now, molecular mechanisms behind SNpc aging have not been fully investigated using high throughput techniques. Here, aging-associated early changes in transcriptome of SNpc were investigated comparing late middle-aged (18 months old) to young (2 months old) mice.
