    Gene–Phenotype Catalogue Provides New Insights into Premature Aging Disorders

    BUFFALO, NY — April 15, 2026 — A new #research paper was #published in Volume 18 of Aging-US on March 30, 2026, titled “A manually curated gene–phenotype catalogue for progeroid syndromes and premature aging.” The study was led by Nuša Likar and Tanja Kunej from the University of Ljubljana, Slovenia. The researchers developed a comprehensive, manually curated catalogue integrating data from 84 scientific publications and the OMIM database. The resulting resource systematically organizes genetic and clinical information on progeroid syndromes, linking 144 genes to 56 syndromes and 160 distinct clinical entities, making it one of the most extensive datasets in this field to date. Using genome–phenome association analysis and protein–protein interaction networks, the study reveals the complex genetic and phenotypic heterogeneity underlying premature aging disorders. The findings highlight strong enrichment in genome maintenance and DNA repair pathways, reinforcing their central role in aging biology. The catalogue also demonstrates how single genes, such as LMNA, can be associated with multiple syndromes, illustrating the pleiotropic nature of genetic variants in progeroid conditions and their broader relevance to human aging mechanisms. “Overall, this study provides a reference resource and framework to support future research into premature aging syndromes and their broader implications for understanding physiological aging.” Overall, the authors present a valuable framework for improving the classification, diagnosis, and study of rare premature aging disorders. Their work not only advances understanding of progeroid syndromes but also offers important insights into the biological processes that drive normal human aging.

    Longevity & Aging Series (S4, E3): Dr. Ricardo Costeira

    In this episode of the Longevity & Aging Series (S4, E3), Dr. Ricardo Costeira of King’s College London joins host Dr. Yuan Zhao of Queen Mary University of London to discuss a research paper he co-authored in Volume 17, Issue 12 of Aging-US, titled “Theobromine is associated with slower epigenetic ageing.” DOI - https://doi.org/10.18632/aging.206344 Corresponding authors - Ramy Saad - ramy.saad@kcl.ac.uk, and Jordana T. Bell - jordana.bell@kcl.ac.uk Video interview - https://www.youtube.com/watch?v=in0z_QApqWQ Longevity & Aging Series - https://www.aging-us.com/longevity About Dr. Yuan Zhao - https://www.qmul.ac.uk/sbbs/staff/yuan-zhao.html Abstract video - https://www.youtube.com/watch?v=S0P1USM8L6E Abstract Theobromine, a commonly consumed dietary alkaloid derived from cocoa, has been linked to extended lifespan in model organisms and to health benefits in humans. We examined associations between circulating levels of theobromine intake, measured using serum metabolomics, and blood-based epigenetic markers of biological ageing in two European human population-based cohorts. Serum theobromine levels were significantly associated with reduced epigenetic age acceleration, as measured by GrimAge (p 2e-7) and DNAmTL (p 0.001) in 509 individuals from the TwinsUK cohort, and both signals replicated in 1,160 individuals from the KORA cohort (p = 7.2e-08 and p = 0.007, respectively). Sensitivity analyses including covariates of other cocoa and coffee metabolites suggest that the effect is specific to theobromine. Our findings indicate that the reported beneficial links between theobromine intake on health and ageing extend to the molecular epigenetic level in humans.

    Decline in Glycolytic ATP Production Proposed as a Fundamental Mechanism Limiting Lifespan

    Aging has long been attributed to a range of biological processes, including DNA damage, telomere shortening, and mitochondrial dysfunction. Yet, these frameworks often describe downstream consequences rather than a single unifying cause. Despite decades of research, a central question remains unresolved: what ultimately determines lifespan across species? Increasing attention has turned to cellular energy metabolism—particularly pathways responsible for rapid ATP generation—as a potential key driver. Understanding how these metabolic changes unfold over time, and how they influence survival, regeneration, and disease, remains a major challenge in aging biology. A new research perspective published in Volume 18 of Aging-US introduces a unifying concept in aging biology, titled “A decline in glycolytic ATP production is the fundamental mechanism limiting lifespan; species with an optimal rate of decline over time survived.” Full blog - https://aging-us.org/2026/04/decline-in-glycolytic-atp-production-proposed-as-a-fundamental-mechanism-limiting-lifespan/ Paper DOI - https://doi.org/10.18632/aging.206356 Corresponding author - Akihiko Taguchi - taguchi@fbri.org Abstract video - https://www.youtube.com/watch?v=rA23radaoqI Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.206356 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - hypothesis, aging, glycolytic ATP production, lifespan, Heterocephalus glaber To learn more about the journal, please visit https://www.Aging-US.com​​ and connect with us on social media at: Bluesky - https://bsky.app/profile/aging-us.bsky.social ResearchGate - https://www.researchgate.net/journal/Aging-1945-4589 X - https://twitter.com/AgingJrnl Facebook - https://www.facebook.com/AgingUS/ Instagram - https://www.instagram.com/agingjrnl/ LinkedIn - https://www.linkedin.com/company/aging/ Reddit - https://www.reddit.com/user/AgingUS/ Pinterest - https://www.pinterest.com/AgingUS/ YouTube - https://www.youtube.com/@Aging-US Spotify - https://open.spotify.com/show/1X4HQQgegjReaf6Mozn6Mc MEDIA@IMPACTJOURNALS.COM

    EDITORS’ CHOICE: Plant-based dietary patterns are associated with slower epigenetic aging

    Each month, we will highlight a paper published in Aging-US chosen as the “Editors’ Choice.” These selections are handpicked by our editors and accompanied by a brief summary, showcasing research with significant impact and novel insights in aging and age-related diseases. _____ In this study, titled “Plant-based dietary patterns are associated with slower epigenetic aging,” the researchers examined whether plant-based dietary patterns are linked to biological aging in large, diverse U.S. populations. Using data from the Atherosclerosis Risk in Communities (ARIC) Study and National Health and Nutrition Examination Survey (NHANES), they analyzed several versions of plant-based diet scores that reflect higher intake of plant foods and lower intake of animal products, as well as distinctions between healthy and less healthy plant-based foods. They then compared these dietary patterns with DNA methylation-based “epigenetic clocks,” which estimate biological age, including GrimAge2, PhenoAge, and HannumAge. The results showed that greater adherence to overall plant-based diets, provegetarian diets, and especially healthy plant-based diets was consistently associated with slower epigenetic aging, meaning participants appeared biologically younger than their chronological age. In contrast, diets higher in less healthy plant-based foods did not show the same benefits. The findings suggest that diets emphasizing whole plant foods and limiting animal products may help slow biological aging at the molecular level.

    ATF5 Required for Maintaining Mitochondrial Homeostasis and Skeletal Muscle Health During Aging

    BUFFALO, NY — April 9, 2026 — A new #research paper was #published in Volume 18 of Aging-US on March 27, 2026, titled “ATF5 is required for the maintenance of mitochondrial homeostasis and skeletal muscle health during aging.” Led by first author Victoria C. Sanfrancesco and corresponding author David A. Hood, both from the Muscle Health Research Centre, School of Kinesiology and Health Science, York University, Toronto, Ontario, Canada, the study investigated the role of activating transcription factor 5 (ATF5) in regulating mitochondrial quality control and skeletal muscle function during aging. Using young and aged mouse models with and without ATF5 expression, the researchers examined how this transcription factor contributes to mitochondrial homeostasis, protein turnover, and stress response pathways. The analysis focused on key mechanisms such as the integrated stress response (ISR) and mitochondrial unfolded protein response (UPRmt), which are essential for maintaining mitochondrial integrity. The authors found that ATF5 plays a critical role in coordinating mitochondrial quality control and adaptive stress signaling in skeletal muscle. Notably, the absence of ATF5 prevented the typical age-related decline in muscle mass but resulted in increased muscle fatigability and elevated mitochondrial reactive oxygen species (ROS) production. Additionally, the loss of ATF5 disrupted normal stress-response signaling and altered protein degradation pathways, highlighting its importance in maintaining muscle function with age. “Collectively, these results suggest that ATF5 functions to maintain mitochondrial quality control and muscle endurance at the expense of muscle mass, and its absence attenuates the normal compensatory stress response to contractile activity with age.” The authors conclude that while ATF5 contributes to preserving mitochondrial function and endurance capacity, its role in regulating muscle mass and stress adaptation is complex. Further studies are needed to clarify how modulation of ATF5 and related pathways could be leveraged to improve muscle health and mitigate age-related decline in mitochondrial function and physical performance.

    Hypertonic Saline Plus Furosemide Linked to Lower Inflammatory and Remodeling Markers in ADHF

    BUFFALO, NY — April 7, 2026 — A new #research paper was #published in Volume 18 of Aging-US on March 26, 2026, titled “Effects of intravenous furosemide plus small-volume hypertonic saline solutions on inflammatory, remodelling markers and epigenetics signatures of patients with congestive acute decompensated heart failure (ADHF).” Led by first author Mario Daidone from University Hospital, Policlinico, Paolo Giaccone, and the University of Palermo, with corresponding author Antonino Tuttolomondo from University Hospital, Policlinico, Paolo Giaccone, and University of Palermo, the randomized trial compared i.v. furosemide plus small-volume hypertonic saline solution (HSS) with i.v. furosemide alone in patients with acute decompensated heart failure due to reduced ejection fraction. The study enrolled 200 subjects, randomly assigning 107 to furosemide plus HSS and 93 to furosemide alone. The authors found that patients treated with i.v. furosemide plus HSS showed lower increases in inflammatory and remodeling biomarkers after saline load, including IL-6, hsTnT, sST2, galectin-3, and NT-proBNP, and the intervention was associated with reduced miR181b expression compared with furosemide alone. These findings suggest that adding small-volume hypertonic saline to loop diuretic therapy may influence both circulating biomarkers and miRNA-related epigenetic signatures in acute heart failure. “Nevertheless, the possible effects of the i.v. furosemide + HSS treatment on natriuretic and inflammatory markers of heart failure deserve further confirmation, whereas the effects of this type of treatment on epigenetic signatures of pathologic mechanisms involved in the left ventricular dysfunction involved in AHF pathogenesis seem to be still not studied.” The authors note that this was a randomized trial in a specific ADHF population, so additional studies will be needed to confirm the durability of the biomarker changes, define the optimal patient groups, and determine whether these molecular effects translate into improved clinical outcomes. Future work may also clarify how the saline strategy interacts with cardiac remodeling and miRNA regulation in larger and more diverse heart failure cohorts.

    BOLD Variability Modulation Linked to Age-Specific Bimanual Performance

    BUFFALO, NY — April 2, 2026 — A new #research paper was #published in Volume 18 of Aging-US on March 24, 2026, titled “Age-specific relationship between the modulation of brain dynamics in response to task demands and bimanual performance.” Led by first author Sara Magalhães Ferreira from Hasselt University, with corresponding author Koen Cuypers from Hasselt University and KU Leuven, the study examined how age affects BOLD variability and its modulation with task demands during a bimanual task. The authors used fMRI in 22 younger and 23 older healthy adults who performed three increasingly complex task conditions. The authors found that older adults showed higher BOLD variability in cerebellar lobule VIIIb and greater modulation across task conditions in sensorimotor and cerebellar regions. Modulation of BOLD variability predicted performance in an age- and region-dependent manner: in younger adults, reduced modulation in sensorimotor and visuospatial areas correlated with better performance, whereas in older adults, increased modulation in the inferior and superior parietal lobules was linked to higher performance. Across groups, better outcomes were associated with greater modulation in the middle occipital gyrus but lower modulation in cerebellar Crus I. “In sum, this study highlights the potential role of BOLD variability modulation in shaping bimanual performance during aging.” The authors note that, while the age-related differences in BOLD dynamics were clear, they did not find robust evidence supporting a brain-behavior relationship in bimanual performance, which limits how directly the neural findings can be interpreted behaviorally. They recommend future work using multimodal imaging, longitudinal designs, and studies that examine both cognitive and motor domains within the same participants to determine whether variability modulation reflects aging, experience, intervention, or broader cross-functional signatures of aging.

    IL6 and IL6R: Opposing Forces of Inflammation That Shape Human Survival

    Inflammation is a double-edged sword. It defends the body against infection and injury, yet when it becomes chronic, it can accelerate aging and fuel the very diseases that shorten human life. For decades, scientists have observed that people with higher levels of inflammatory markers like interleukin-6 (IL6) and C-reactive protein (CRP) tend to have shorter lifespans. But the critical question has always been: does inflammation cause mortality, or does it merely reflect underlying disease? A research paper, titled “Causal effects of inflammation on long-term mortality: A mendelian randomization study” was published in Volume 18 of Aging-US by an international team of researchers, provides a definitive answer by using a powerful genetic technique to untangle cause from effect. The team’s investigation demonstrates that the IL6 inflammatory pathway has a direct causal impact on human survival—but with a surprising twist: two components of the same pathway pull in opposite directions.
