Excess reactive oxygen species disrupt redox homeostasis, inducing oxidative stress, resulting in mitochondrial dysfunction and damage. Furthermore, defective or impaired mitochondria might intensify ROS production. This \"necessary evil\" serves dual functions: regulating signaling, apoptosis, proliferation, differentiation, autophagy, and immunological responses while simultaneously inflicting oxidative damage on lipids, proteins, and DNA, hence contributing to numerous diseases. Thus, the targeted suppression of mitochondrial ROS-induced oxidative damage and dysfunction by mitochondria-targeted antioxidants (MTAs) represents a precise therapeutic strategy that has attracted growing interest and offers substantial opportunities for clinical application by directly alleviating oxidative stress at its origin within affected cells. Lipophilic cation-linked MTAs, amino acid- and peptide-based MTAs, metallo-complex-based MTAs, and nanoparticle-based MTAs (Nano-MTAs) can selectively localize to mitochondria and diminish excessive mitochondrial ROS. Incorporating these MTAs into precision medicine facilitates tailored therapies based on individual mitochondrial dysfunction characteristics and disease-specific redox imbalances. This review classifies current mitochondria-targeted antioxidants according to the characteristics of their targeting moieties and examines their composition and antioxidant efficacy. We also evaluate nanoparticle-based MTAs, including liposomes, DQAsomes, solid lipid nanoparticles, MITO-Porters, micelles, dendrimers, nanoemulsions, metal nanoparticles, quantum dots, and nanopolyplexes. Furthermore, we summarize recent experimental findings regarding MTAs across diverse disease models including cancer, neurological disorders (e.g., Alzheimer’s, Huntington’s, Parkinson’s, ataxia, TBI, and epilepsy); cardiovascular diseases; asthma; COPD; auditory impairments; diabetic complications; ocular, renal, hepatic, and inflammatory disorders; sepsis; infertility; aging-longevity; and their potential as antibiotics to clarify the evidence supporting their therapeutic efficacy.</div></div>","PeriodicalId":72106,"journal":{"name":"Advances in redox research : an official journal of the Society for Redox Biology and Medicine and the Society for Free Radical Research-Europe","volume":"17 ","pages":"Article 100142"},"PeriodicalIF":2.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145624035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigated SOD2′s metastatic function by assessing its transcriptomic effects in OVCA433 ovarian cancer cells cultured in low-attachment conditions that induce MCAs, mimicking anchorage-independent states in malignant ascites. SOD2 siRNA-mediated knockdown effects in MCAs were compared to adherent culture conditions. RNA sequencing and pathway analysis revealed that SOD2 lies upstream of pro-metastatic pathways, including PI3K/AKT signaling. Notably, in MCAs, cytokine and immune cell signaling pathways were more significantly enriched following SOD2 knockdown. We previously identified SIRT3 as an important SOD2 activity regulator in MCAs. While SIRT3 knockdown resulted in minor transcriptional changes, we identified that FOXO3 and ELF4 transcription factors, important for stress response and immune regulation, are downregulated by both SIRT3 and SOD2 knockdown. Comparing SOD2 knockdown transcriptional changes to the Cancer Genome Atlas, we found SOD2 expression strongly associates with pro-tumorigenic immune signaling in serous ovarian cancer specimens, including genes identified downstream of SOD2 from our siRNA screen. Moreover, SOD2 expression correlated with signatures related to pro-tumorigenic neutrophil and T-regulatory cell populations.

This review summarizes the roles of key dietary antioxidants vitamin A, melatonin, essential trace minerals (copper, zinc, magnesium), flavonoids, polyphenols, and L-carnitine, in mitigating oxidative stress in farm animals. Vitamin A supports epithelial integrity, scavenges ROS, and upregulates antioxidant enzymes via redox-sensitive transcription factors. Melatonin functions as a potent free radical scavenger and activates the Nrf2 pathway to enhance antioxidant enzyme expression. Copper, zinc, and magnesium act as cofactors for enzymatic antioxidants such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), helping maintain redox homeostasis. Flavonoids and polyphenols, including quercetin, curcumin, and EGCG, exert antioxidant effects by scavenging ROS, chelating metal ions, and enhancing endogenous defense pathways. L-carnitine improves mitochondrial function, reduces ROS generation, and enhances glutathione activity, especially during stress conditions such as heat, transport, or weaning. Supplementation with these compounds across species has been shown to increase antioxidant enzyme activity, reduce oxidative biomarkers like malondialdehyde (MDA), and improve immunity, metabolic efficiency, and performance. These natural or synthetic antioxidants offer promising nutritional strategies to improve oxidative stability, health, and productivity in farm animals. Their integration into feed programs provides a sustainable and cost-effective approach to improving animal welfare and resilience under intensive production systems.</div></div>","PeriodicalId":72106,"journal":{"name":"Advances in redox research : an official journal of the Society for Redox Biology and Medicine and the Society for Free Radical Research-Europe","volume":"16 ","pages":"Article 100138"},"PeriodicalIF":2.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144748957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The redox environment can directly affect excitation contraction coupling, calcium handling and inflammation but also regulate key signalling pathways involved in mitochondrial quality control and proteostasis. Additionally, exercise-induced regulation of microRNAs (miRs) levels can provide a feedback mechanism to fine tune the adaptive response. Endogenous ROS produced during exercise arise from diverse sources including NADPH oxidases (NOX), mitochondria, xanthine oxidase (XO) and phospholipase A2 (PLA2). As high levels of ROS can potentially be damaging, there is a sophisticated, organelle-specific antioxidant network in skeletal muscle that includes superoxide dismutases (SODs), catalases (CATs), peroxiredoxins (PRDXs) and glutathione peroxidases (GPXs). Due to their abundance, location and catalytic activity, emerging evidence highlights the potential role of the PRDX family as central mediators in coordinating the redox signalling cascade as a result of increased ROS generation. Several exercise related miRs contain binding sites for redox sensitive and exercise associated transcription factors (TFs), moreover some miRs can target these TFs, providing a potential feedback mechanism to maintain cellular homeostasis following disruption of the redox environment. The interconnected roles of redox signalling and miRs are discussed in exercise-induced skeletal muscle adaptations. Furthermore, the therapeutic potential of targeting these interconnected pathways to mitigate muscle ageing and dysfunction, can provide valuable insights into strategies for optimising muscle health and enhancing healthspan.</div></div>","PeriodicalId":72106,"journal":{"name":"Advances in redox research : an official journal of the Society for Redox Biology and Medicine and the Society for Free Radical Research-Europe","volume":"16 ","pages":"Article 100133"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144196228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
