These pathological changes impair cellular bioenergetics and regenerative capacity, accelerating cardiac deterioration. However, targeted interventions to mitigate these effects remain limited. This research investigates the therapeutic potential of CISD1 activation as a novel strategy to counteract aging-associated cardiac decline. Using advanced Immunoinformatic approaches, including molecular docking, protein structure modelling, and molecular dynamics simulations, we assess the role of CISD1 upregulation in enhancing mitochondrial bioenergetics, reducing oxidative stress, and preserving telomere integrity. Our Immunoinformatic findings reveal that CISD1 activation stabilizes mitochondrial function, mitigates oxidative damage, and slows telomere attrition, thereby sustaining cardiomyocyte function and delaying cellular senescence. Our research identifies 4'-Methoxy-3', 5,7-trihydroxy flavanone as a potential small-molecule activator of CISD1, offering a promising pharmacological approach to modulate mitochondrial dynamics in aging cardiomyocytes. By directly addressing the mechanistic link between CISD1, mitochondrial stability, and telomere preservation, this research bridges a critical gap in understanding age-related cardiomyopathy and provides a foundation for targeted therapeutic interventions. Our findings suggest that CISD1 activation could restore cellular homeostasis in aged cardiac tissues, reducing the risk of heart failure and other aging-related cardiovascular diseases. These insights advance age-related disease intervention strategies by targeting fundamental molecular pathways involved in cardiomyocyte aging.</p>","PeriodicalId":8909,"journal":{"name":"Biogerontology","volume":"26 2","pages":"68"},"PeriodicalIF":4.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review describes the cellular and molecular changes in the brain microvasculature of the neurovascular unit (NVU) that contribute to the development of BBB dysfunction in aging, such as endothelial cell senescence, oxidative stress, and degradation of tight junction proteins. Stroke severity and recovery are exacerbated by BBB breakdown, leading to neuroinflammation, neurotoxicity, and cerebral oedema while identifying molecular mechanisms such as the NLRP3 inflammasome, matrix metalloproteinases (MMPs), and non-coding RNAs (e.g., miRNAs and circRNAs) that drive BBB disruption in aging and stroke. Real-time assessment of BBB permeability in stroke pathophysiology is made possible using advanced imaging techniques, such as dynamic contrast-enhanced MRI and positron emission tomography. Furthermore, biomarkers, including claudin-5, PDGFRβ, or albumin concentration, serve as markers of BBB integrity and vascular health. Restoration of BBB function and stroke recovery with emerging therapeutic strategies, including sirtuin modulators (SIRT1 and SIRT3 activators to enhance endothelial function and mitochondrial health), stem cell-derived extracellular vesicles (iPSC-sEVs for BBB repair and neuroprotection), NLRP3 inflammasome inhibitors (MCC950 to attenuate endothelial pyroptosis and inflammation), hydrogen-rich water therapy (to counteract oxidative stress-induced BBB damage), and neuropeptides such as cortistatin (to regulate neuroinflammation and BBB stability), is promising.

Data from 131 participants (101 older adults, 71.5±4.9 years; 30 young adults, 25.5±3.9 years) were analyzed. Skeletal muscle mass was assessed using bioimpedance analysis, and hand grip strength was measured with a dynamometer.

Older adults exhibited lower levels of glutamic acid, isoleucine, leucine, phenylalanine, kynurenine, and kynurenine-to-tryptophan (KYN:TRP) ratio compared to younger individuals (all p<0.05). In older adults, branched-chain and essential amino acids correlated positively with skeletal muscle index (SMI) and hand grip strength, whereas in young adults, only glutamic acid, proline, and KYN:TRP showed positive associations with SMI (all p<0.05).

Meanwhile, cellular senescence leads to irreversible cell cycle arrest, triggering the senescence-associated secretory phenotype which contributes to chronic inflammation, tissue remodeling, and fibrosis. Dysregulation of these pathways accelerates lung aging and disease progression by promoting oxidative stress, mitochondrial dysfunction, and epigenetic alterations. Recent studies indicate that HIF and senescence interact at multiple levels, where HIF can both induce and suppress senescence, depending on cellular conditions. While transient HIF activation supports tissue repair and stress resistance, chronic dysregulation exacerbates pulmonary pathologies. Furthermore, emerging evidence suggests that targeting HIF and senescence pathways could offer new therapeutic strategies to mitigate age-related lung diseases.

This study explores the concept of longevity assurance genes, which primarily function within genetic pathways responsible for repair and maintenance. These pathways encompass molecular and metabolic processes as well as organ- and system-level functions. To investigate this, we employed comparative transcriptomics to analyze gene expression patterns across three age groups with progressively decreasing brain plasticity: native postnatal day seven brains, and young and old naïve and lesioned rat male brains. Analysis revealed a highly symmetrical distribution of upregulated and downregulated genes in postnatal day 7 brains. In contrast, the gene expression profiles of post-stroke brains exhibited significant asymmetry, with a disproportionate increase in upregulated genes compared to downregulated ones in both young and old post-ischemic brains. Gene variance in juvenile brains predominantly reflected processes associated with brain plasticity (e.g., Dcx, Tubb2b, Dok4, Dpysl5) and cell proliferation (e.g., Bex4). Conversely, gene expression variance in young and aged post-stroke brains was largely linked to inflammatory pathways, driven by cytokine and chemokine signaling. Notably, several genes specifically upregulated in aged brains were identified, including Ehd4, Fut7, Lilrb4, Plek, Slfn13, Slc14a1, and Smpdl3a. Immune genes that facilitate synaptic plasticity during early postnatal brain development-through processes such as pruning and sprouting to establish new connections in response to external stimuli-also contribute to post-stroke damage, confirming the concept of antagonistic pleiotropy.
