CALB1 and RPL23 Are Essential for Maintaining Oocyte Quality and Function During Aging

open access: yesAging Cell, EarlyView.
This study investigates the mechanisms of oocyte aging in mice, identifying Calb1 and Rpl23 as key genes involved in calcium ion homeostasis and mitochondrial function. Knockdown of these genes led to mitochondrial dysfunction, meiotic defects, and spindle assembly abnormalities, while their overexpression partially rescued age‐related oocyte defects ...

Plasma Proteomic Signature as a Predictor of Age Advancement in People Living With HIV

open access: yesAging Cell, EarlyView.
We developed a prediction model of biological age based on 77 plasma proteins that were associated with chronological age in two independent cohorts of PLHIV and one cohort of people without HIV. PLHIV exhibited an increased age advancement that was positively associated with previous co‐infections and non‐AIDS‐related comorbidities, a higher ...

Longevity Humans Have Youthful Erythrocyte Function and Metabolic Signatures

open access: yesAging Cell, EarlyView.
Longevity humans have “a youthful erythrocyte function and metabolism” with a youth‐like oxygen release and anti‐oxidative capability to combat tissue hypoxia and improve healthspan. ABSTRACT Longevity individuals have lower susceptibility to chronic hypoxia, inflammation, oxidative stress, and aging‐related diseases.

Reduction of DNA Topoisomerase Top2 Reprograms the Epigenetic Landscape and Extends Health and Life Span Across Species

open access: yesAging Cell, EarlyView.
This study demonstrates that reducing the enzyme topoisomerase Top2 or its mammalian homolog TOP2B promotes longevity across multiple species, including yeast, worms, and mice. At the cellular/molecular level, TOP2B reduction mitigates the major cellular aging hallmarks such as epigenetic alterations, cell senescence, lysosomal biogenesis, and ...

Healthy Aging Metabolomic and Proteomic Signatures Across Multiple Physiological Compartments

open access: yesAging Cell, EarlyView.
The association of the aging scores with the clinical covariates suggests increased inflammation, strong predisposition to iron deficiency anemia, decline in muscle mass, and renal and hepatic functions with accelerated aging. ABSTRACT The study of biomarkers in biofluids and tissues expanded our understanding of the biological processes that drive ...

Activated mTOR Signaling in the RPE Drives EMT, Autophagy, and Metabolic Disruption, Resulting in AMD‐Like Pathology in Mice

open access: yesAging Cell, EarlyView.
Our study reveals that overactivation of both mTOR complexes through mLST8 in RPE cells triggers AMD‐like pathology and cellular dysfunction. This finding highlights the critical role of balanced mTOR signaling in retinal health and suggests that targeting both complexes could be therapeutic for AMD treatment.

Age‐Dependent Regulation of Hippocampal Inflammation by the Mitochondrial Translocator Protein in Mice

open access: yesAging Cell, EarlyView.
The role of mitochondrial translocator protein (TSPO) in hippocampal inflammation is age‐dependent, with TSPO deletion drastically exacerbating inflammation in aged mice, while dampening it in young mice. This TSPO–aging interaction was linked to NF‐kβ and interferon regulatory transcriptional networks. TSPO deletion exacerbated age‐dependent depletion
