Transcriptomic landscape of human primary stromal cells (fibroblasts, endothelial cells and mesenchymal stem cells) upon therapy-induced senescence (genotoxic chemotherapy）

ABSTRACT: As a prominent hallmark of senescent cells, the senescence-associated secretory phenotype (SASP) accumulates over the course of chronological aging and in diverse age-related diseases, and is a crucial driver of chronic inflammation and aging-associated phenotypes. In humans, senescent cells accumulate in multiple tissues at different rates, from 2- to 20-fold when comparing young (<35 years) to old (>65 years) healthy donors. For decades of years, the identification, characterization and pharmacological elimination of senescent cells have gained attention in the research field of aging and age-related disorders. However, the non-specificity of current senescence markers and the existence of different senescence programs strongly limits these tasks. Despite recent advances in high-throughput technologies, there is still a lack of in-depth comparison of the senescence-associated expression profile among distinct cell lineages in the tissue microenvironment. Here, we chose to profile the genome-wide expression of several primary normal human stromal cell lines including HBF1203, Huc068, HUVEC and IMR90 upon therapy-induced senescence (TIS), with the aim to determine molecular regulators of senescence phenotypes and define the potential contribution of senescent cells to human age-related pathologies. These data may provide a baseline to further explore how senescent cells arising in the local microenvironment can promote tissue dysfunction and organ degeneration in the course of an individual aging.

Transcriptomic landscape of mouse pulmonary alveolar cells upon chronological aging and/or anti-senescence intervention

Project description:As a critical hallmark of senescent cells, the senescence-associated secretory phenotype (SASP) develops over the course of chronological aging and in diverse age-related conditions, and is a key driver of chronic inflammation and age-associated phenotypes. For years, the identification, characterization and pharmacological targeting of senescent cells have gained substantial attention in the field of aging and age-related pathologies. Pyruvate dehydrogenase kinase 4 (PDK4) is an important mitochondrial matrix enzyme in cellular energy regulation, and drives the metabolic reprogramming of mammalian cells towards a Warburg-like effect. Upregulation of PDK4 is responsible for enhanced production of lactate in the tissue microenvironment of aged organisms, potentially causing chronic inflammation and contributing to accelerated aging. Targeting PDK4 holds the potential to prevent lactate accumulation, minimize tissue damage and postpone senescence-associated systemic aging. Here we profiled the genome-wide expression of cells (mainly fibroblasts) in mouse pulmonary alveolus, with the assistance of laser capture microdissection (LCM) of primary lung tissues. Animals were allowed to naturally age, or subject to treatment by PDK4-IN (an anthraquinone derivative, PDK4 inhibitor). These data may provide a baseline to further determine the effects of lactate reduction by PDK4-specific targeting on cellular senescence, tissue homeostasis, and explore the wide implications of PDK4 expression in organismal aging and age-related morbidity.

Transcriptomic profiling of human senescent cells upon treatment with the senolytic agent procyanidin C1

Project description:In the course of aging, the long term retention of senescent cells in vivo, a process mainly attributed to highly expressed BCL-family proteins, chronically damages tissues mainly through a senescence-associated secretory phenotype (SASP). It has been documented that accumulation of senescent cells accelerates aging and contributes to age-related diseases. Indeed, senescent cells can be removed by several strategies, thus preventing occurrence of chronic disorders and prolonging lifespan and healthspan. Senolytics, which eliminate senescent cells by pharmacological intervention, have recently emerged as a new line of therapeutic agents to ameliorate diverse age-related pathologies. Achieving the goal using natural or synthetic agents would have a tremendous impact on the quality of life. We report the potential of procyanidin C1 (PCC1), an epicatechin trimer natural product derived from plant sources including grape, apple, and cocoa, in targeting senescent cells via induction of apoptosis. This study demonstrates the efficacy of PCC1 in minimizing the influence of senescent cells in tissue microenvironment and provides a strong rationale for its future use in aging control and geriatric medicine.

Transcriptomic landscape of human primary stromal cells upon therapy-induced senescence (genotoxic chemotherapy and ionizing radiation)

Project description:Cellular senescence is a permanent state of cell cycle arrest that promotes tissue remodeling during embryonic development and after trauma or injury, but can also contribute to the decline of organ regenerative potential and tissue normal function, to local and systemic inflammation, and to tumorigenesis in aged organisms. For years, the identification, characterization, and pharmacological elimination of senescent cells have gained attention in the research field of aging and age-related diseases. However, the non-specificity of current senescence markers and the existence of different senescence programs strongly limit these tasks. Here, we profiled the genome-wide expression of primary normal human prostate stromal cells (PSC27) upon therapy-induced senescence (TIS), with the aim to determine molecular regulators of senescence phenotypes and define the inherent correlation of gene expression pattern with the extensive senescence-associated 3D genome reorganization. This TIS-specific configuration of chromosome architecture brings active genes located in genomic regions adjacent to senescence-associated heterochromatin domains (SAHDs) in close spatial proximity and favors their expression. These data may provide a baseline to further explore show how multi-omics and 3D mapping can identify critical features of cellular senescence and discover key determinants of senescence and SAHF formation in the genome-wide landscape.

A comprehensive multi-omics signature of doxorubicin-induced cellular senescence in the postmenopausal human ovary

Project description:A major aging hallmark is the accumulation of cellular senescence burden. Over time senescent cells contribute to tissue deterioration through chronic inflammation and fibrosis driven by the Senescence-Associated Secretory Phenotype (SASP). The human ovary is one of the first organs to age, and prominent age-related fibroinflammation within the ovarian microenvironment is consistent with the presence of senescent cells. However, bona fide senescent cells have not been validated in the human ovary. Therefore, we established a doxorubicin-induced model of cellular senescence to define a signature of ovarian senescent cells. Explants of human postmenopausal ovarian cortex and medulla were treated with doxorubicin for 24 hours followed by culture for up to 10 days in doxorubicin-free medium. Tissue viability was confirmed by histology, lack of apoptosis, and continued glucose consumption by explants. Single nuclei sequencing and proteomics revealed an unbiased signature of ovarian senescence. We identified distinct senescence profiles for the cortex and medulla, driven predominantly by epithelial and stromal cells. Proteomics uncovered subregional differences in addition to 120 proteins common to the cortex and medulla SASP. Integration of transcriptomic and proteomic analyses revealed 26 shared markers, defining a robust senotype of doxorubicin-induced senescence unique to the postmenopausal ovary. A subset of these proteins - Lumican, SOD2, MYH9 , and Periostin - were mapped onto native tissue to reveal compartment-specific localization. This senotype will help determine the role of cellular senescence in ovarian aging and inform the development of biomarkers to identify and therapeutic applications to slow or reverse ovarian aging, senescence, and cancer.

Transcriptomic profiling of senescent human blood vessel cells upon medicinal intervention with ginkgo boliba extract or rattan tea extract

Project description:Aging and age-related pathologies can be delayed by specifically targeting the senescence-associated secretory phenotype (SASP), a hallmark feature of senescent cells. Achieving the goal using natural or synthetic agents would have a tremendous impact on the quality of lifespan and burden of age-related chronic diseases. We report the potential of ginkgo boliba extract (GBE), a commonly used dietary supplement and traditional herbal medicine for hundreds of years in China as an antioxidant and free radical scavenger, or rattan tea extract (RTE), a medicinal agent used for many years for the treatment of inflammation, fatty liver, tumor, diabetes and hyperlipidemia, in targeting senescent cells via suppression of the SASP. This study demonstrates the efficacy of GBE and RTE as medicinal products in controlling the influence of senescent human blood vessel cells and provides a strong rationale for their future use in aging control and geriatric medicine.

GNPS - Exosomes Released from Senescent Cells and Isolated from Human Plasma Reveal Aging-associated Proteomic Signatures

Project description:Senescence emerged as a significant mechanism of aging and age-related diseases, offering an attractive target for clinical intervention. Senescent cells release senescence-associated secretory phenotype (SASP), including exosomes that may act as signal transducers between distal tissues, propagating secondary senescence and signaling throughout the body. However, the composition of exosome SASP remains underexplored, presenting an opportunity for novel unbiased discovery. Here, we present a detailed lipidomic analysis of exosome SASP using mass spectrometry from senescent primary human lung fibroblasts and human plasma from young and older individuals.

Proteomic analysis of small extracellular vesicles derived from human ESCs

Project description:Tissue-resident stem cell senescence leads to stem cell exhaustion, which is a major cause of physiological and pathological aging. Stem cells-derived extracellular vesicles(SCs-EVs) have been reported to possess therapeutic potential in preclinical studies for diverse diseases. However, whether SCs-EVs could rejuvenate senescent tissue stem cell to prevent age-related disorders still remains unknown. Here, we showed that chronic application of human embryonic stem cells-derived extracellular vesicles (hESCs-sEVs) rescues senescent bone marrow MSCs (BM-MSCs) function and prevents age-related bone loss in aging mice. Transcriptome analysis revealed that hESCs-sEVs treatment up-regulates the expression of genes involved in anti-aging, stem cell proliferation and osteogenic differentiation in BM-MSCs. Furthermore, liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis identified 4122 proteins encapsulated in hESCs-sEVs. Bioinformatics analysis predicated that protein components in the hESCs-sEVs function in a synergistic way to induce the activation of several canonical signaling pathways, including Wnt, Sirtuin, AMPK, PTEN signaling, which results in the up-regulation of anti-aging genes in BM-MSCs and then the recovery of senescent BM-MSCs function. Collectively, our findings reveal the effect of hESCs-sEVs in reversing BM-MSCs senescence and age-related osteogenic dysfunction, and thereby preventing age-related bone loss. Given that hESCs-sEVs could alleviate senescence of tissue-resident stem cells, it might be a promising therapeutic candidate for age-related diseases.

Chemotherapy-induced cellular senescence is characterized by aberrant lipid regulation and lipid peroxidation

Project description:As normal cells approach their proliferative limit, they arrest to undergo replicative senescence, displaying large cell size, flat morphology and activation of senescence-associated beta-galactosidase (SA-b-Gal). A subset of normal or tumor cells exposed in vitro or in vivo to chemotherapy agents such as etoposide perform a related response with a similar cellular phenotype dubbed therapy-induced senescence (TIS). High cellular heterogeneity in samples including TIS cells can impede confident determination of senescence-specific factors, frustrating discovery of markers and targets for functional analysis. As a TIS study model, we treated murine melanoma cells with the chemotherapeutic etoposide, applied a live-cell fluorescent SA-b-Gal senescence assay, and utilized fluorescence-activated cell sorting (FACS) to enrich TIS cells. Enriched senescent cell samples were subjected to mass spectrometry and label-free quantitative proteomics analysis, alongside proliferating and quiescent cell samples. Systems biology analysis revealed that senescent cells overexpress proteins and pathways regulating glycolipid processing, lipid metabolism, and lipid peroxidation. Senescence-associated activation of numerous glycosidases was observed, along with elevated cell surface expression of several major lipid regulatory proteins. Senescent cells were found to contain abundant lipid droplets and to import various types of extracellular lipids in correlation with extent of SA-b-Gal expression, and tumor cells were observed to spontaneously senesce in the presence of excess ceramide or triglycerides. Redox-induced lipid peroxidation, resulting in accumulation of cellular reactive aldehydes and consequent expression of aldehyde detoxification enzymes, was observed to be a key feature of TIS induced by three DNA-damaging chemotherapeutics.

Expression data from senescence-inducible Suv39h1-ERT2 primary mouse Emu-myc B-cell lymphoma

Project description:Treatment-induced senescence (TIS) is a DNA damage-triggered stress-response program, resulting in terminal arrest of affected cells. TIS plays an important role in cancer therapy, as many tumor cells would undergo TIS instead of apoptosis when exposed to standard chemotherapy regimens. The contribution of TIS to overall disease outcome is, however, unclear. To address this, we use lymphoma cells with conditional expression of the senescence-essential factor Suv39h1 (regulatable by 4-hydroxi-tamoxifen). Only cells with active Suv39h1 would undergo TIS in response to chemotherapy. Suv39h1 inactivation during the chemo-treatment would prevent TIS induction, while inactivation in fully senescent cells would allow outgrowth from the TIS cell cycle arrest. Such post-senescent cells (PS) show very different biological behavior than the cells growing in senescence-incompetent setting - never senescent (NS). The molecular characteristics of each of these treatment conditions are analyzed here by assessing global transcriptome data. We used global gene expression profiling by microarrays to gain insight in the molecular programme underlying the chemotherapy response in primary Emu-myc transgenic B-cell lymphomas.
