Emerging evidence suggests a rising incidence of CRC in younger adults, emphasizing the urgent need for innovative therapeutic strategies. The increasing attention on circular economy approaches has heightened interest in discovering natural compounds derived from recycled agri-food waste. These compounds are particularly promising due to their large array of bioactive functional components. In this study, we investigated the efficacy of a green compost derived from coffee wastes, known as humic substance (HS), in reducing CRC cell viability. Chemical characterization of HS from composted coffee waste (HS-COF) using ¹³C Cross-Polarization Magic-Angle Spinning Nuclear Magnetic Resonance (CPMAS NMR) spectroscopy and offline pyrolysis Tetramethylammonium Hydroxide-Gas Cromatography Mass-Spectrometry (TMAH-GC-MS) revealed an abundance of phenolic compounds derived from lignin residues. Specifically, chlorogenic acid (ClA) was identified as the major component and primary agent responsible for the biological effects of HS-COF. Our <i>in vitro</i> results demonstrated that HS-COF selectively inhibits HT-29 cell viability, migration, and proliferation by inducing programed cell death through the activation of the tumor necrosis factor-<i>α</i> (TNF-<i>α</i>) signaling pathway and disruption of calcium homeostasis. Additionally, HS-COF exhibited a significant antioxidant activity, indicating its potential to combine a cytotoxic profile with a safety profile, thereby minimizing adverse effects on healthy cells. In conclusion, this study proposes HS-COF as a valuable adjuvant in CRC therapy, paving the way for its application in the pharmaceutical industry.</p>","PeriodicalId":19657,"journal":{"name":"Oxidative Medicine and Cellular Longevity","volume":"2025 ","pages":"8034350"},"PeriodicalIF":0.0,"publicationDate":"2025-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12767483/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145912677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The NRF2-KEAP1 pathway is a pivotal cellular defense mechanism against oxidative stress, regulating the transcription of cytoprotective genes. Pharmacological NRF2 activation has emerged as a promising strategy to mitigate oxidative stress-related pathologies; however, challenges regarding target specificity, pharmacodynamics, efficacy, and safety remain unresolved. Isoeugenol, a phenylpropanoid found in essential oils, has traditionally been recognized as a skin allergen but is now gaining attention for its potential as an NRF2 activator. Emerging evidence suggests that isoeugenol exerts antioxidant, anti-inflammatory, and neuroprotective effects and modulates metabolic disorders such as diabetes mellitus. Despite its therapeutic potential, the direct correlation between isoeugenol's effects and NRF2 activation remains underexplored. Existing studies indicate that isoeugenol may activate NRF2 through multiple mechanisms, including covalent modification of KEAP1 cysteine residues, increased AKT activation and GSK3β inactivation, and glutathione depletion leading to reactive oxygen species (ROS) generation. Understanding these activation pathways is critical for leveraging isoeugenol as a therapeutic agent. This review provides a comprehensive analysis of isoeugenol's role in modulating NRF2 activity and its implications for treating oxidative stress-driven diseases. By integrating current findings, this review highlights new insights into the therapeutic potential of isoeugenol in translational medicine. We propose future research directions to optimize its application in clinical settings, paving the way for more targeted and effective NRF2-based interventions in chronic disease management.</p>","PeriodicalId":19657,"journal":{"name":"Oxidative Medicine and Cellular Longevity","volume":"2025 ","pages":"7695056"},"PeriodicalIF":0.0,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12767388/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145912418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our 2012 review of 21 studies, we found that most patient breast tumors exhibited increased GSH levels compared to peritumoral tissue. However, there was no clear relationship between GSH levels and histological grade, clinical stage, or patient outcome. For this update, database searches found 59 studies that reported the levels of any of 10 metabolites, including GSH, cysteine (Cys), ascorbate (Asc), and taurine (Tau), in breast tumor tissues. The increase in the number of studies profiling tumor metabolites is mainly due to the use of an array of relatively new metabolomics technologies. However, many of these metabolomics methods are not designed to prevent sample oxidation during tissue procurement and processing. Despite this, these recent studies confirm that the levels of most of the antioxidants or related metabolites are increased in patient breast tumor tissues compared to normal tissues. In addition, poor patient outcomes are often associated with tumor tissues with higher GSH and lower Tau levels. GSH levels also increase with histological grade. There are no clear trends in the relationship between any of the antioxidant levels and tumor stage or genetically defined subtypes. Clearer trends may emerge with more uniform tissue sampling, preparation, and assay procedures. In addition, the increased use of spatial metabolomics methods may help to clarify the relationship between antioxidant levels and clinical markers.</p>","PeriodicalId":19657,"journal":{"name":"Oxidative Medicine and Cellular Longevity","volume":"2025 ","pages":"1811206"},"PeriodicalIF":0.0,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12767394/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145912623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
