It affects a significant proportion of the global population and is correlated with physical and mental consequences such as cognitive decline, anxiety, chronic fatigue, poor concentration, and memory impairment. Interestingly, it is also linked to ageing and age-related diseases (cardiovascular, metabolic, and neurodegenerative). On the other hand, as we age, DNA methylation patterns undergo significant changes. These have been used to develop the so-called epigenetic clocks that estimate the biological age linked to the environment and the risk of diseases. Few studies have evaluated the association between insomnia and epigenetic clocks, providing insight into the role of insomnia in ageing acceleration. Therefore, in the present study, we carried out an epigenetic analysis by using Illumina EPICv.2 array on 63 older adults (&gt; 60 years old, <i>n</i> = 33 with insomnia vs. <i>n</i> = 30 control) to evaluate the relation between insomnia and epigenetic ages (HorvathAGE, HannumAGE, PhenoAGE, SkinBloodClock, GrimAGE, DunedinPACE, DNAmTL). As a result, we found an increased acceleration and correlation between GrimAGE and SkinBloodClock and a significant reduction in the DNAmTL in individuals with insomnia. An EWAS analysis showed a global pattern of hypomethylation and an enrichment of several proteostasis and oxidative pathways. In conclusion, our results suggest that insomnia increases GrimAGE and SkinBloodClock acceleration and may be participating in telomere shortening. Additionally, changes in DNA methylation patterns induced by insomnia impact proteostasis and oxidative stress.</p>","PeriodicalId":12730,"journal":{"name":"GeroScience","volume":"69 1","pages":""},"PeriodicalIF":5.6,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oral intake is the typical route of administration tested for the vast majority of gerotherapeutic candidates, including curcumin, but efficacy is dependent upon good oral bioavailability and pharmacokinetics. However, unlike FDA-approved oral medications, many natural compounds, such as curcumin, have poor oral bioavailability, which may explain their limited success in translation. To overcome these inherent limitations, we tested a novel solvent-based formulation of concentrated curcumin (VASCEPTOR®), developed for effective skin penetration and delivery of high amounts of bioactive curcuminoids directly to the circulation on aging and age-related conditions.

One of the molecular pathways related to longevity in various model organisms revolves around lowering AKT1 levels. This prompted our in silico drug screen for small molecules capable of mimicking the transcriptional effects of <i>AKT1</i> knockdown. We found topoisomerase inhibitors as a top candidate longevity-drug class. Evaluating multiple compounds from this class in <i>C. elegans</i> revealed that the topoisomerase inhibitor amonafide has the greatest benefit on healthspan and lifespan. Intriguingly, the longevity effect of amonafide was not solely dependent on <i>DAF-16/FOXO</i>, the canonical pathway for lifespan extension via <i>AKT1</i> inhibition. We performed RNA-seq on amonafide-treated worms and revealed a more youthful transcriptional signature, including the activation of diverse molecular and cellular defense pathways. We found the mitochondrial unfolded protein response (UPR<sup>mt</sup>) regulator <i>afts-1</i> to be crucial for both improved healthspan and extended lifespan upon amonafide treatment. Moreover, healthspan was partially dependent on the immune response transcription factor <i>zip-2</i> and the integrated stress response transcription factor <i>atf-4</i>. We further examined the potential of amonafide in age-related disease. Treating a <i>C. elegans</i> model for Parkinson’s disease with amonafide improved mobility.
