Age-Dependent KLK8 Upregulation Contributes to Elevated Susceptibility to Ventilator-Induced Lung Injury in the Elderly Mice

8 hours 48 minutes ago
There is a growing contradiction between the rising demand for mechanical ventilation among the elderly and their heightened sensitivity to ventilator-induced lung injury (VILI). This discrepancy compels us to explore therapeutic targets for VILI in elderly patients. Our research revealed that aging increases the sensitivity of pulmonary endothelial cells to low-magnitude mechanical stretch. By analyzing transcriptome sequencing data from lung tissues of humans and mice at different ages, as...

Reporting quality, effect sizes, and biases for aging interventions: a methodological appraisal of the DrugAge database

1 day 8 hours ago
Though interest has grown significantly over the past decades in interventions that may slow the aging process, most evidence for these interventions still comes from experiments in non-human animals. These studies may suffer from design, quality and reporting issues. The quality and reporting of preclinical studies have not yet been studied systematically in anti-aging research. Here we analyzed the DrugAge database, assessing reporting study quality, bias and effect sizes across 667 anti-aging...

Impact of 5-HT7 receptor gene deletion on memory and affective behaviors in young and aged mice

1 day 8 hours ago
The 5-HT7 receptor subtype is expressed throughout the brain, including the cortex and hippocampus, and it has been implicated in the molecular mechanisms underlying memory and affective behaviors. Although aging also affects memory and behavior, how 5-HT7 receptor interacts with age-related changes of these phenotypes has not been fully elucidated. To further understand the role of 5-HT7 receptor on memory and affective behaviors across the lifespan, we assessed age-related changes in locomotor...

Odoribacter splanchnicus rescues aging-related intestinal P-glycoprotein damage via GDP-L-fucose secretion

1 day 8 hours ago
Intestinal P-glycoprotein (P-gp/ABCB1) is a key barrier limiting xenobiotic absorption, yet its functional decline with aging is poorly understood. Here, we show that gut microbiota dysbiosis contributes to age-associated P-gp deficiency. Integrated multi-omics analyses of human cohorts and murine models identify Odoribacter splanchnicus (O. splanchnicus) as a key commensal species whose depletion impairs intestinal P-gp function. Mechanistically, O. splanchnicus encodes GDP-mannose 4,...

Epigenetic age acceleration, telomere length, and neurocognitive function in long-term survivors of childhood cancer

1 day 8 hours ago
Survivors of childhood cancer are prone to neurocognitive impairment and premature aging, raising concerns about early onset dementia. In this cross-sectional study, 1413 survivors of childhood cancer complete a neuropsychological battery. Mean leukocyte telomere length residual (mLTL) and epigenetic age acceleration (EAA) from five different epigenetic clocks, are derived from linear regression of mLTL or epigenetic age on chronological age. Among survivors treated with CNS-directed therapy,...

Midbrain extracellular matrix and microglia are associated with cognition in aging mice

1 day 8 hours ago
Synapse dysfunction is tightly linked to cognitive changes during aging. Emerging evidence suggests that microglia and the extracellular matrix (ECM) can potently regulate synapse integrity and plasticity. Yet the brain ECM, and its relationship with microglia, synapses, and cognition during aging remains virtually unexplored. In this study we combine ECM-optimized proteomic workflows with histological analyses in aging mice and discover regional differences in ECM composition and aging-induced...

Space radiation induces distinct senescent phenotypes: Implications for space travel

1 day 8 hours ago
As Earth's magnetic field weakens, space radiation begins to pose a significant threat to the health of not only space travelers, but the world's population. Space radiation, comprising high-energy and high-charge ions, creates distinct clusters of DNA damage and dense macromolecular damage that result in the accumulation of senescent cells (SnCs) known to play a critical role in promoting multimorbidity. Here, we demonstrate that human fibroblasts exposed to different forms of space radiation...

Perturbation of multiprotein complexes in skeletal muscle induces protective proteases in the CNS that degrade pathogenic proteins

1 day 8 hours ago
Many cellular functions rely on multiprotein complexes and their stoichiometric assembly. Reducing the levels of individual complex components can perturb this process and induce corrective stress responses. In addition to local outcomes, cellular stress in one tissue can induce long-distance responses in other tissues. Here, we used muscle-targeted RNAi to examine the systemic stress responses induced by muscle-specific genetic perturbation of four distinct multiprotein complexes: the...

Plasma biomarkers of alzheimer's disease and related dementias are associated with cognitive change in community-dwelling older individuals in Australia and the US

1 day 8 hours ago
Plasma biomarkers of Alzheimer's disease and related dementias (ADRD) are associated with the risk of dementia. However, the extent to which they could reflect cognitive ageing, and whether this is consistent across factors known to influence biomarkers (e.g. sex and chronic kidney disease) and in different populations, is unknown. Data were from a diverse community-dwelling cohort of older individuals without dementia in Australia (n = 11,930) and the US (n = 1,181). Global cognition, verbal...

Asymmetrical end structures of leading and lagging telomeres in Saccharomyces cerevisiae dictate the nature of the end replication problem

1 day 8 hours ago
The end replication problem refers to incomplete replication of parental DNA at telomeres, a process whose molecular depiction is hampered by the complex nature of telomere ends. Here, we recapitulate this process using a synthetic de novo telomere in Saccharomyces cerevisiae and delineate distinct molecular fates of telomere ends in vivo. We show that the lagging-strand telomeres carry a ∼10 nt 3' overhang, while the leading-strand telomeres have a Yku-protected blunt end, a feature that is...

Spatial and single-cell transcriptomics reveal the reorganization of cerebellar microglia with aging

1 day 8 hours ago
The cerebellum, essential for motor coordination and increasingly recognized for its role in cognition, is typically considered more resilient to aging and largely spared from hallmark Alzheimer's disease (AD) pathology. However, transcriptomic analyses across fifteen mouse brain regions revealed that the cerebellum undergoes some of the earliest and most pronounced age-related changes. To investigate cerebellar aging, we applied single-nucleus RNA sequencing (RNA-seq), microglial bulk RNA-seq,...

Inhibition of 15-hydroxy prostaglandin dehydrogenase promotes cartilage regeneration

1 day 8 hours ago
Aging or injury to the joints can lead to cartilage degeneration and osteoarthritis (OA), for which there are limited effective treatments. We found that expression of 15-hydroxy prostaglandin dehydrogenase (15-PGDH) is increased in the articular cartilage of aged or injured mice. Both systemic and local inhibition of 15-PGDH with a small molecule inhibitor (PGDHi) led to regeneration of articular cartilage and reduction in OA-associated pain. Using single cell RNA-sequencing and multiplexed...

Intracranial self-stimulation mitigates spatial task deficits, modifies miR-146a and miR-495 serum levels and restores hippocampal NRF2 levels in a rat model of sporadic Alzheimer's disease

1 day 8 hours ago
CONCLUSION: Prolonged MFB-ICSS treatment mitigates cognitive deficits, modulates circulating levels of miRNA-495 and miR-146a, restores hippocampal NRF2 levels, and preserves corpus callosum integrity in the SAD rat model by STZ injection. These findings highlight the therapeutic potential of MFB-ICSS as a non-pharmacological intervention in AD. Furthermore, this study confirms NRF2 as a target of miR-495 in the context of AD.
