Epigenetic mechanisms shaping cytoskeleton dynamics in cardiovascular diseases
Cytoskeleton is an important component of cell structure and function. In the cardiovascular system, it is involved in the remodeling process of a variety of cardiovascular diseases, including cardiac fibrosis, valvular disease, atrial fibrillation, thoracic aortic aneurysm and vascular stiffness related changes. Recent studies have shown that there is a significant synergy between cytoskeletal regulation and epigenetic processes. Notably, epigenetic alterations have been identified as one of...
Positioning TERT at the apex of aging
Aging is a biologically tractable process. Telomerase reverse transcriptase (TERT) has emerged as an upstream regulator coordinating several hallmarks of aging across preclinical models. Beyond maintaining telomeres, TERT influences mitochondrial health, epigenetic regulation, inflammation and stem cell function. Multiple translational strategies are being explored to modulate TERT. In mice and human cell models, restoration of physiological-range TERT expression characteristic of younger cells,...
Performance of the SmartMe&You serious video games for home telemonitoring is related to cognitive status and resting-state electroencephalographic markers in healthy and Parkinson's disease participants
Unsupervised serious video games on the SmartMe&You home telemonitoring platform may enable the assessment of cognitive fluctuations in older individuals, with or without cognitive deficits. Here, we tested their validity in cognitively unimpaired older adults (Healthy) and patients with mild cognitive impairment and mild to moderate dementia due to Parkinson's disease (PDCD). Such validity was assessed using Mini-Mental State Examination (MMSE) scores and resting-state eyes-closed...
How epigenetic clocks tick: unpacking the black box by deciphering biological pathways and transcriptomic signatures of accelerated aging
Epigenetic clocks derived from DNA methylation robustly predict biological aging, health, and mortality, yet differ substantially in their predictive profiles. The biological processes underlying these differences remain poorly understood. Using data from 3227 participants in the U.S. Health and Retirement Study, with contemporaneous DNA methylation and RNA-sequencing, we examined the five most widely used epigenetic clocks (Horvath, Hannum, PhenoAge, GrimAge, and DunedinPACE). We conducted...
Prevalence of sensory impairments and associations with symptoms of anxiety and depression in US older adults
CONCLUSIONS: Objectively measured sensory impairments were highly prevalent among US older adults and were associated with an increased risk of anxiety, but not depressive symptoms over a short follow-up duration. Self-reports considerably underestimated true prevalence of mild- to- moderate impairment, emphasizing the need for routine objective assessment in clinical practice and research.
Association of T-EAT-10 and NUFFE-TR scores with a history of aspiration pneumonia in nursing home residents: a cross-sectional study
CONCLUSIONS: The T-EAT-10 is a practical and highly effective screening tool for identifying aspiration pneumonia risk in institutionalized elderly populations. A clinical threshold of >12 is recommended for identifying high-risk residents, which is substantially higher than the standard dysphagia screening cut-off. Systematic screening using T-EAT-10 and NUFFE-TR should be integrated into routine geriatric care in nursing homes to improve preventive strategies.
Bcl11a orchestrates multilineage integrity in aging hematopoiesis by regulating multipotent progenitor fate decisions
Aging hematopoiesis exhibits progressive myeloid skewing and impaired lymphopoiesis, driving age-related blood disorders. We show that multipotent progenitors (MPPs) mediate this lineage imbalance. Aging expands myeloid-biased MPP3 cells while functionally compromising MPP4 lymphoid potential, collectively skewing hematopoietic output toward the myeloid lineage. We identify Bcl11a as a dosage-sensitive regulator of MPP fate: Bcl11a suppresses Fer to restrain premature myeloid differentiation in...
Stroke burden and associated predictors in Ghana: a Bayesian analysis of the WHO study on global ageing and adult health
CONCLUSION: Public health strategies should emphasize physical activity, healthy diets, weight control, and improved management of chronic diseases. These efforts align with the sustainable development goal 3 (SDG 3); Good Health and Well-being, particularly Target 3.4, which aims to reduce premature mortality from non-communicable diseases through prevention and treatment by 2030.
Gut Metabolism Links Precision Nutrition, Exercise, and Healthspan in Drosophila melanogaster
Longevity-promoting interventions commonly entail functional trade-offs, raising the unresolved question of whether lifespan extension necessarily compromises physiological performance. Here, utilizing a chemically defined diet (CDD) in Drosophila melanogaster, we systematically evaluated a multimodal intervention combining methionine restriction (MR), taurine supplementation (Tau), and moderate exercise. This combinatorial approach additively extended lifespan, preserved reproductive capacity,...

Scientists discover a protein that protects the brain from Alzheimer’s damage
A protein called SORLA may act as a powerful defense against the toxic tau tangles involved in Alzheimer’s disease. Mice with extra SORLA had less tau accumulation, less brain atrophy, and healthier connections between neurons, while mice without it experienced more severe damage. The findings also revealed a possible drug target that could help control harmful activity in supporting brain cells.
