Our analysis leveraged nationally representative data from 2,136 participants aged ≥ 50 years in the 1999-2002 NHANES cycles. Multivariable linear regression models with survey weights were constructed to evaluate dose-response relationships, complemented by restricted cubic splines (RCS) for nonlinearity detection. Machine learning optimization included comparative evaluation of nine algorithms through five-fold cross-validation, with model interpretability enhanced via SHapley Additive exPlanations (SHAP) analysis. Higher omega-3 intake (Tertile 3 [T3] vs Tertile 1 [T1]) demonstrated inverse associations with HorvathAge (β = -1.07), particularly for ALA intake (T3 ≥ 1.512 g/d: β = -1.11). Contrastingly, moderate-to-high omega-3 intake (T2 ≥ 0.917 g/d: β = 0.04; T3: β = 0.04) and individual components (ALA_T3: β = 0.04; DHA_T3 ≥ 0.041 g/d: β = 0.05; EPA_T3 ≥ 0.011 g/d: β = 0.03) exhibited positive correlations with HorvathTelo. RCS modeling revealed distinct patterns: linear inverse correlation for HorvathAge versus nonlinear J-shaped association with Horvathtelo. Among ML models, Linear Support Vector Machines achieved superior predictive performance. SHAP feature importance analysis consistently ranked omega-3 composite measures highest, followed by constituent components (ALA > DHA > EPA). Our findings suggest a potential dual role of omega-3 in biological aging modulation: higher intake associates with decelerated epigenetic aging while maintaining telomere length homeostasis.

As ALAN affects the circadian clock with concomitant effects on stress and free radical physiology, we hypothesised that night exposure to artificial light may affect the rate of aging. We have investigated this by exposing pre-pubertal female rats to 15 days of artificial light at night (ALAN). A direct effect of ALAN on physiology was evident by the significant increase in body weight of ALAN exposed group. Consequently, biomarkers of aging: nitric oxide (NO), lipid peroxidation in terms of Malondialdehyde (MDA), protein carbonyl levels (PCO) and plasma membrane redox system (PMRS) were found to be significantly elevated in blood plasma. Increase of these parameters are positive indicators that ALAN may induce accelerated aging even in young animals by affecting their redox biology. Also, tissue specific expression of genes (TNFα, LC3β, NSE and SIRT1) which are established molecular correlates of healthy aging, metabolic rate, autophagy and normal antioxidant physiology were compared between ALAN exposed and control animals. Tissue specific effect on expression of TNFα, LC3β, NSE and SIRT1 was found when exposed to ALAN. These results highlight the negative effects of altered circadian rhythm on young rats.

This study sought to investigate the role of miR-217/FOXO3 axis in endothelial cell senescence.

Dual-luciferase reporter assay confirmed FOXO3 as a direct miR-217 target.

Aging is a multidimensional phenomenon characterized by the progressive impairment of various cellular structures and organelle functions. The basis of human organ senescence is cellular senescence. Currently, with the increase in human life expectancy and the increasing proportion of the elderly population, the economic burden of diseases related to aging is becoming increasingly heavy worldwide, and an in-depth study of the mechanism of cellular aging is urgently needed. Aging, a multifactor-driven biological process, is closely related to mitochondrial dysfunction, which is the core pathological basis of a variety of age-related diseases. This article systematically reviews the molecular pathways by which mitochondrial dysfunction drives aging through multidimensional mechanisms such as metabolic reprogramming, epigenetic regulation, telomere damage, autophagy imbalance, and the senescence-associated secretory phenotype. Metabolic reprogramming promotes tumor progression and exacerbates energy metabolism disorders through abnormal activation of the PI3K/Akt/mTOR signaling pathways. The sirtuin family (such as SIRT1 and SIRT3) maintains mitochondrial homeostasis by regulating PGC-1α, FOXO3 and other targets. Telomere shortening directly inhibits mitochondrial biosynthesis through the p53-PGC-1α axis, leading to oxidative stress accumulation and a decline in organ function. The dual roles of autophagy (removing damaged mitochondria or inducing apoptosis) suggests that its homeostasis is essential for delaying aging. The SASP mediates the inflammatory microenvironment through the cGAS‒STING pathway, which is not only a marker of aging but also a driving force of disease progression. Future studies need to integrate multiomics techniques to analyze the interaction network between mitochondria and other organelles, such as the endoplasmic reticulum and lysosomes, and explore precise intervention strategies targeting sirtuins, AMPK and telomerase. Combined therapies targeting metabolic reprogramming or SASP inhibition are expected to provide new ideas for delaying aging and preventing age-related diseases.</p>","PeriodicalId":8909,"journal":{"name":"Biogerontology","volume":"26 4","pages":"142"},"PeriodicalIF":4.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12241157/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144599160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
