Age-associated Gene Expression Changes in Mouse Sweat Glands

BUFFALO, NY- May 14, 2024 – A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 8, entitled, “Characterization of age-associated gene expression changes in mouse sweat glands.” Evaporation of sweat on the skin surface is the major mechanism for dissipating heat in humans. The secretory capacity of sweat glands (SWGs) declines during aging, leading to heat intolerance in the elderly, but the mechanisms responsible for this decline are poorly understood. In this new study, researchers Alexandra G. Zonnefeld, Chang-Yi Cui, Dimitrios Tsitsipatis, Yulan Piao, Jinshui Fan, Krystyna Mazan-Mamczarz, Yutong Xue, Fred E. Indig, Supriyo De, and Myriam Gorospe from the National Institutes of Health’s National Institute on Aging investigated the molecular changes accompanying SWG aging in mice, where sweat tests confirmed a significant reduction of active SWGs in old mice relative to young mice. “We first identified SWG-enriched mRNAs by comparing the skin transcriptome of Eda mutant Tabby male mice, which lack SWGs, with that of wild-type control mice by RNA-sequencing analysis.” This comparison revealed 171 mRNAs enriched in SWGs, including 47 mRNAs encoding ‘core secretory’ proteins such as transcription factors, ion channels, ion transporters, and trans-synaptic signaling proteins. Among these, 28 SWG-enriched mRNAs showed significantly altered abundance in the aged male footpad skin, and 11 of them, including Foxa1, Best2, Chrm3, and Foxc1 mRNAs, were found in the ‘core secretory’ category. Consistent with the changes in mRNA expression levels, immunohistology revealed that higher numbers of secretory cells from old SWGs express the transcription factor FOXC1, the protein product of Foxc1 mRNA. “In sum, our study identified mRNAs enriched in SWGs, including those that encode core secretory proteins, and altered abundance of these mRNAs and proteins with aging in mouse SWGs.” DOI - https://doi.org/10.18632/aging.205776 Corresponding authors - Chang-Yi Cui - cuic@mail.nih.gov, and Myriam Gorospe - gorospem@grc.nia.nih.gov Author interview - https://www.youtube.com/watch?v=7A_TREuSv54 Video abstract - https://www.youtube.com/watch?v=yJEphCaMhK8 Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.205776 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - aging, FOXA1, BEST2, FOXC1, ectodysplasin/Eda, Tabby About Aging-US Aging publishes research papers in all fields of aging research including but not limited, aging from yeast to mammals, cellular senescence, age-related diseases such as cancer and Alzheimer’s diseases and their prevention and treatment, anti-aging strategies and drug development and especially the role of signal transduction pathways such as mTOR in aging and potential approaches to modulate these signaling pathways to extend lifespan.

The Beginning of Becoming a Human: A Review

BUFFALO, NY- May 9, 2024 – A new review #paper was #published as the #cover of Volume 16, Issue 9 by Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), entitled, “The beginning of becoming a human.” According to birth certificates, the life of a child begins once their body comes out of the mother’s womb. In this new review, researchers Polina A. Loseva and Vadim N. Gladyshev from Harvard Medical School pose the controversial question: when does their organismal life begin? Science holds a palette of answers—depending on how one defines a human life. In 1984, a commission on the regulatory framework for human embryo experimentation opted not to answer this question, instead setting a boundary, 14 days post-fertilization, beyond which any experiments were forbidden. Recently, as the reproductive technologies developed and the demand for experimentation grew stronger, this boundary may be set aside leaving the ultimate decision to local oversight committees. While science has not come closer to setting a zero point for human life, there has been significant progress in our understanding of early mammalian embryogenesis. It has become clear that the 14-day stage does in fact possess features, which make it a foundational time point for a developing human. Importantly, this stage defines the separation of soma from the germline and marks the boundary between rejuvenation and aging. “We explore how different levels of life organization emerge during human development and suggest a new meaning for the 14-day stage in organismal life that is grounded in recent mechanistic advances and insights from aging studies.” DOI - https://doi.org/10.18632/aging.205824 Corresponding authors - Polina A.

Association Between Neighborhood Deprivation and DNA Methylation in an Autopsy Cohort

BUFFALO, NY- May 8, 2024 – A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 8, entitled, “The association between neighborhood deprivation and DNA methylation in an autopsy cohort.” Previous research has found that living in a disadvantaged neighborhood is associated with poor health outcomes. Living in disadvantaged neighborhoods may alter inflammation and immune response in the body, which could be reflected in epigenetic mechanisms such as DNA methylation (DNAm). In this new study, researchers Lindsay Pett, Zhenjiang Li, Sarina Abrishamcar, Kenyaita Hodge, Todd Everson, Grace Christensen, Marla Gearing, Michael S. Kobor, Chaini Konwar, Julia L. MacIsaac, Kristy Dever, Aliza P. Wingo, Allan Levey, James J. Lah, Thomas S. Wingo, and Anke Hüls from Emory University, University of British Columbia, BC Children’s Hospital Research Institute, Centre for Molecular Medicine and Therapeutics, and Atlanta VA Medical Center used robust linear regression models to conduct an epigenome-wide association study examining the association between neighborhood deprivation (Area Deprivation Index; ADI), and DNAm in brain tissue from 159 donors enrolled in the Emory Goizueta Alzheimer’s Disease Research Center (Georgia, USA). “We found one CpG site (cg26514961, gene PLXNC1) significantly associated with ADI after controlling for covariates and multiple testing (p-value=5.0e-8).” Effect modification by APOE ε4 was statistically significant for the top ten CpG sites from the EWAS of ADI, indicating that the observed associations between ADI and DNAm were mainly driven by donors who carried at least one APOE ε4 allele. Four of the top ten CpG sites showed a significant concordance between brain tissue and tissues that are easily accessible in living individuals (blood, buccal cells, saliva), including DNAm in cg26514961 (PLXNC1). This study identified one CpG site (cg26514961, PLXNC1 gene) that was significantly associated with neighborhood deprivation in brain tissue. PLXNC1 is related to immune response, which may be one biological pathway how neighborhood conditions affect health. “The concordance between brain and other tissues for our top CpG sites could make them potential candidates for biomarkers in living individuals.” DOI - https://doi.org/10.18632/aging.205764 Corresponding author - Anke Hüls - anke.huels@emory.edu Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.205764 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts About Aging-US Aging publishes research papers in all fields of aging research including but not limited, aging from yeast to mammals, cellular senescence, age-related diseases such as cancer and Alzheimer’s diseases and their prevention and treatment, anti-aging strategies and drug development and especially the role of signal transduction pathways such as mTOR in aging and potential approaches to modulate these signaling pathways to extend lifespan.

Inflammatory and Metabolic Biomarkers and Accelerated Aging in Cardiac Catheterization Patients

BUFFALO, NY- May 7, 2024 – A new #research paper was #published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 8, entitled, “Associations among NMR-measured inflammatory and metabolic biomarkers and accelerated aging in cardiac catheterization patients.” Research into aging has grown substantially with the creation of molecular biomarkers of biological age that can be used to determine age acceleration. Concurrently, nuclear magnetic resonance (NMR) assessment of biomarkers of inflammation and metabolism provides researchers with new ways to examine intermediate risk factors for chronic disease. In this new study, researchers Henry Raab, Elizabeth R. Hauser, Lydia Coulter Kwee, Svati H. Shah, William E. Kraus, and Cavin K. Ward-Caviness from the U.S. Environmental Protection Agency and Duke University used data from a cardiac catheterization cohort to examine associations between biomarkers of cardiometabolic health and accelerated aging assessed using both gene expression (Transcriptomic Age) and DNA methylation (Hannum Age, GrimAge, Horvath Age, and Phenotypic Age). “This study utilizes the CATHGEN cohort from the Jiang et al. study to investigate associations between multiple epigenetic and transcriptomic aging biomarkers and a broad array of NMR-based measures of inflammation, lipid homeostasis, and diabetes risk.” Linear regression models were used to associate accelerated aging with each outcome (cardiometabolic health biomarkers) while adjusting for chronological age, sex, race, and neighborhood socioeconomic status. Their study shows a robust association between GlycA and GrimAge (5.71, 95% CI = 4.36, 7.05, P = 7.94 × 10−16), Hannum Age (1.81, 95% CI = 0.65, 2.98, P = 2.30 × 10−3), and Phenotypic Age (2.88, 95% CI = 1.91, 3.87, P = 1.21 × 10−8). The researchers also saw inverse associations between apolipoprotein A-1 and aging biomarkers. “These associations provide insight into the relationship between aging and cardiometabolic health that may be informative for vulnerable populations.” DOI - https://doi.org/10.18632/aging.205758 Corresponding authors - Cavin K.

Novel Deep Proteomic Approach Unveils Molecular Signatures Affected by Aging and Resistance Training

BUFFALO, NY- May 1, 2024 – A new #researchpaper was #published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 8, entitled, “A novel deep proteomic approach in human skeletal muscle unveils distinct molecular signatures affected by aging and resistance training.” The skeletal muscle proteome alterations to aging and resistance training have been reported in prior studies. However, conventional proteomics in skeletal muscle typically yields wide protein abundance ranges that mask the detection of lowly expressed proteins. In this new study, researchers Michael D. Roberts, Bradley A. Ruple, Joshua S. Godwin, Mason C. McIntosh, Shao-Yung Chen, Nicholas J. Kontos, Anthony Agyin-Birikorang, Max Michel, Daniel L. Plotkin, Madison L. Mattingly, Brooks Mobley, Tim N. Ziegenfuss, Andrew D. Fruge, and Andreas N. Kavazis from Auburn University, Seer, Inc., and The Center for Applied Health Sciences adopted a novel deep proteomics approach whereby myofibril (MyoF) and non-MyoF fractions were separately subjected to protein corona nanoparticle complex formation prior to digestion and Liquid Chromatography Mass Spectrometry (LC-MS). “Specifically, we investigated MyoF and non-MyoF proteomic profiles of the vastus lateralis muscle of younger (Y, 22±2 years old; n=5) and middle-aged participants (MA, 56±8 years old; n=6). Additionally, MA muscle was analyzed following eight weeks of resistance training (RT, 2d/week).” Across all participants, the number of non-MyoF proteins detected averaged to be 5,645±266 (range: 4,888–5,987) and the number of MyoF proteins detected averaged to be 2,611±326 (range: 1,944–3,101). Differences in the non-MyoF (8.4%) and MyoF (2.5%) proteomes were evident between age cohorts, and most differentially expressed non-MyoF proteins (447/543) were more enriched in MA versus Y. Biological processes in the non-MyoF fraction were predicted to be operative in MA versus Y including increased cellular stress, mRNA splicing, translation elongation, and ubiquitin-mediated proteolysis. RT in MA participants only altered ~0.3% of MyoF and ~1.0% of non-MyoF proteomes. “In summary, aging and RT predominantly affect non-contractile proteins in skeletal muscle. Additionally, marginal proteome adaptations with RT suggest more rigorous training may stimulate more robust effects or that RT, regardless of age, subtly alters basal state skeletal muscle protein abundances.” DOI - https://doi.org/10.18632/aging.205751 Corresponding author - Michael D.
