🩺 Longevity + Treatments 💪
A study led by the Chinese Academy of Sciences and Xuanwu Hospital Capital Medical University identifies betaine as a kidney-derived compound that mimics exercise’s anti-aging effects. The research shows that long-term exercise increases betaine production, alleviating cellular aging in kidney, vascular, and immune cells, and reducing systemic inflammation.
Senescence-resistant human mesenchymal progenitor cells have shown potential in countering aging in primates.
A meta-analysis of preclinical and clinical studies indicates that Traditional Chinese Medicine (TCM) compounds may delay aging, enhance cognition, and reduce cardiovascular risk by modulating oxidative stress, immunity, endocrine function, and lipid metabolism.
Researchers have developed a new non-viral system, niosomes, for genetic modification of senescent cells to treat age-related diseases. Niosomes showed superior transfection efficiency and less cytotoxicity than commercial reagents, presenting a promising tool for age-related disease treatment.
The study reveals vitamin C promotes keratinocyte proliferation and epidermal thickness by inducing DNA demethylation of proliferation-related genes. This suggests potential therapeutic benefits for skin thinning, including aging-related conditions.
🧬 Longevity + Science 🧪
Chronic diseases’ rise is examined through the lens of evolutionary medicine and life history theory, highlighting an imbalanced metabolic axis involving IGF-1, mTOR, AMPK, and Klotho. The authors suggest that modern environmental mismatches exacerbate the issue and propose further research into understanding health risks, the origins of health and disease, and the potential for therapeutic interventions.
A study identifies 9 aging-related cell populations and 17 transcriptional and protein markers, along with 5 metabolic markers associated with stem cell aging in dogs. Mesenchymal stem cells, particularly those overexpressing NMNAT1, can delay or reverse aging in dogs.
Digital biomarkers of ageing can monitor physiological systems in adults, offering potential in promoting healthy ageing and longevity. These biomarkers, derived from wearable or nonwearable technologies, span eight physiological systems and are categorized by capture methods, validity, generalisability, responsiveness to interventions, associations with clinical outcomes, and cost-effectiveness.
Stem cells progressively lose their ability to sustain tissue homeostasis and support regeneration as organisms age. Researchers have identified five features that characterize aged stem cells, which provide insight into the aging process and serve as targets for therapeutic strategies aiming to rejuvenate stem cell function and extend tissue health span.
Redox-sensitive High mobility group box 1 (HMGB1) drives systemic cellular senescence, which contributes to aging and age-related diseases. Targeting extracellular HMGB1 might offer a potential therapy for preventing aging-related pathologies.
🧑🤝🧑 Longevity + Teams 📰
The Biomarkers of Aging–NIA Joint Symposium 2024 offered a comprehensive look into emerging biomarkers, emphasizing longitudinal studies, population diversity, and multiomic integration. Key contributions from researchers like Luigi Ferrucci, Steve Horvath, Vadim Gladyshev, and Nir Barzilai advanced discussions on mechanistic biomarkers, epigenetic clocks, and drug repurposing initiatives such as FAST, underscoring a growing consensus on the need for harmonized, clinically relevant aging measures.
Mayo Clinic’s AI tool, StateViewer, can identify nine types of dementia, including Alzheimer’s, from a single scan. The tool improves early and precise diagnosis, potentially slowing cognitive decline and maintaining independence longer.
Longevity clinics are urged to adopt shared best practices for improved care quality and reproducibility. Emphasis is placed on evidence-led interventions, AI-integrated diagnostics, and longitudinal outcome tracking. The white paper also addresses the gap in women’s health within the longevity paradigm, calling for more targeted research and intervention.
Researchers at Tufts have created Anthrobots, tiny multicellular organisms formed from human cells, which express both ancient and embryonic genes, effectively turning back their biological clock. This method could illuminate developmental diseases and aid in regenerative medicine without genetic manipulation.
💡Featured Article 🌟
The article “An evolutionary medicine and life history perspective on aging and disease: Trade-offs, hyperfunction, and mismatch” by Jacob E. Aronoff and Benjamin C. Trumble explores the rise in chronic diseases through the lens of evolutionary medicine and life history theory. The authors propose that an imbalance in the metabolic axis between growth and proliferation (anabolic processes) and maintenance and dormancy (catabolic processes) is central to understanding aging and disease. Key mechanisms such as IGF-1, mTOR, AMPK, and Klotho are highlighted as crucial players in this metabolic axis.
The hyperfunction theory of aging is discussed, which suggests that anabolic mechanisms like mTOR contribute to aging and disease. The authors introduce the Brain-Body Energy Conservation model, which links hyperfunction theory with energetic trade-offs that can lead to hypofunction and catabolic health risks, including impaired immunity. Modern environmental mismatches are identified as exacerbating these processes.
For individuals interested in experimenting with treatments that may influence longevity, the article suggests that understanding the roles of IGF-1, mTOR, AMPK, and Klotho in human subsistence populations and their relation to lifestyle changes is crucial. The developmental origins of health and disease and social determinants of health disparities are also important areas for future research.
The authors emphasize the need for studies on exceptionally long-lived species to uncover potential trade-offs and costs associated with their longevity. They discuss implications for therapeutics, cautioning against overly suppressing anabolic metabolism, which could introduce catabolic health risks. The concept of a “Goldilocks zone” is introduced, where a balance between anabolic and catabolic processes is optimal. Additionally, the authors note that treatments tested in shorter-lived species with greater anabolic imbalance may be less effective in humans due to species-specific constraints.
