This study investigates how corin influences microglial inflammatory activation and its underlying mechanisms. Corin expression in rat ICH brain tissue was assessed at multiple time points. To assess corin's effect on neurological function and microglial inflammation, ICH rats and oxygen-glucose deprivation plus hemin (OGD/H)-stimulated HAPI microglia were treated with corin-encoding lentivirus. Neurobehavioral performance was evaluated using the Morris water maze (MWM). Microglial activation was assessed via Iba-1, iNOS, and Arg-1 expression, cytokine secretion, and migration assays. To determine whether AMPK mediates corin's effects, cells were co-treated with Compound C (an AMPK inhibitor) and corin lentivirus. Corin expression decreased in ICH rat brain tissue, reaching its lowest level on day 3 post-ICH. Corin overexpression protected against ICH-induced neuronal apoptosis and improved neurological deficits as confirmed by MWM. Moreover, corin overexpression reduced microglial activation and inflammation in both ICH rats and OGD/H-stimulated microglial cells, ameliorated mitochondrial dysfunction, and increased the p-AMPK/AMPK ratio. The protective effects of corin on cell migration, inflammation, and mitochondrial function were reversed by Compound C, indicating AMPK is a downstream mediator of corin. Targeting corin offers a promising therapeutic strategy for ICH by reducing neuroinflammation and mitochondrial damage through AMPK activation and modulation of microglial inflammatory phenotype polarization.

Using the liver as a model system, we deconstruct this 'imperfect repair'. We posit that it is driven by a pro-fibrotic, non-resolving microenvironment sustained by complex crosstalk between functionally heterogeneous senescent cells and non-senescent scar-associated cell (SAC) populations (including macrophages, endothelial cells (ECs), and hepatic stellate cells (HSCs)). This pathological ecosystem is further shaped by the spatial context of hepatic zonation collapse, and the dysregulation of core signaling hubs, like WNT, Transforming Growth Factor (TGF)-β, and YAP and TAZ (YAP/TAZ). Viewing aging through the lens of imperfect repair provides a unifying framework linking senescence, inflammation, and fibrosis. This perspective shifts the therapeutic paradigm from targeting single senescent cells toward engineering the pathological niche itself, and redirects focus from end-stage disease, to the sub-clinical, spatial origins of tissue vulnerability.

It is orchestrated by a complex polygenic architecture involving numerous small-effect variants distributed across diverse biological pathways, giving rise to striking interindividual variation in aging trajectories and lifespan. Over the past decade and a half, genome-wide association studies (GWAS) have uncovered multiple loci associated with lifespan, healthspan, exceptional longevity, and aging, converging on key biological processes such as lipid metabolism, inflammation, insulin/IGF signaling, and DNA repair. These discoveries have illuminated conserved molecular networks underlying the regulation of aging and longevity. Nevertheless, the identified variants collectively account for only a modest fraction of heritability, underscoring that aging and longevity arise from the cumulative and coordinated actions of myriad common alleles within complex biological networks. In this minireview, we synthesize major genetic insights from GWAS of aging and longevity, delineate recurrent pathways and molecular themes, and discuss how these findings refine our understanding of the genomic foundations of lifespan variation. We further highlight outstanding challenges, including phenotypic heterogeneity, ancestry-specific effects, and the limited predictive power of current models, and propose conceptual directions for future research aimed at establishing a more comprehensive and mechanistic framework for the genetic architecture of human aging and healthy longevity.

While reactive oxygen species (ROS) are known to induce nuclear morphology changes, mechanisms underlying these effects remain elusive, particularly regarding nuclear assembly. We hypothesized that mitotic cells might exhibit increased susceptibility to ROSinduced nuclear deformation due to the dynamic nature of nuclear envelope during mitosis, i.e., disassembly and reassembly. Interestingly, we discovered that exposure of mitotic cells to hydrogen peroxide (H2O2) resulted in persistence of lamin aggregates during early mitosis, which coincided with aberrant nuclear morphology. Further investigation revealed a dampening effect of H2O2 on Cdk1, a pivotal kinase governing mitotic entry. Our in vitro kinase assays demonstrated that H2O2 mediated reduction of Cdk1 activity, resulting in diminished phosphorylation of lamin, a key Cdk1 substrate. Notably, restoration of Cdk1 activity rescued lamin phosphorylation, thereby mitigating lamin aggregation. Furthermore, persistence of lamin aggregation during mitotic entry correlated with premature reassembly of lamin during mitotic exit, affecting nuclear envelope reassembly. These findings collectively suggest that ROS-mediated perturbation of Cdk1 activity during early mitosis can trigger lamin aggregation that affects lamin reassembly, thereby disrupting nuclear morphology. Our study elucidates a novel mechanism by which ROS can disrupt nuclear architecture by modulating Cdk1 activity during mitosis.

The emerging discipline of precision geronutrition integrates the principles of geroscience with precision nutrition, aiming to delay the onset of age-related functional decline by modulating fundamental molecular mechanisms, such as nutrient-sensing pathways (mTOR, AMPK, and sirtuins), inflammaging, and oxidative stress. A major barrier to progress has been the absence of validated biomarkers that can quantify biological aging and assess intervention efficacy. Recent advances in biological aging clocks, in particular DNA methylation-based epigenetic clocks, provide powerful tools to objectively measure biological age, and evaluate the impact of nutritional interventions. This review discusses how personalized dietary strategies, guided by multi-omics data (genomic, metabolomic, and microbiome profiles), can decelerate aging trajectories. We propose that individualized daily nutrition, aligned with an individual's unique biological characteristics, represents a targeted and actionable approach to extend healthspan. The integration of dynamic aging clocks into nutritional intervention frameworks will be essential to transition from a diseaseoriented model to a preventive, healthspan-centered paradigm.
