This condition exacerbates metabolic disruptions by activating Toll-like receptor 4 (TLR4) on macrophages, leading to the release of pro-inflammatory cytokines and subsequent insulin resistance. Eicosapentaenoic acid (EPA; C20:5 (n-3)), an omega-3 polyunsaturated fatty acid, has demonstrated anti-inflammatory and antioxidative properties, but its precise mechanisms of action in mitigating LPS-induced stress remain unclear. This study investigates the pathways through which C20:5 (n-3) alleviates LPS-induced oxidative stress and inflammation in macrophages. C20:5 (n-3) pretreatment significantly reduced LPS-induced inflammatory responses, decreasing IL-1β and IL-6 expression and IL-1β secretion, and lowering the percentage of HLA-DR<sup>+</sup> macrophages. C20:5 (n-3) also attenuated ER stress, evidenced by reduced expression of ATF4, DDIT3, HSPA5/GRP78, BIP, and CHOP at both gene and protein levels. Oxidative stress was mitigated, as shown by decreased HIF1α expression, reduced ROS levels, and preservation of mitochondrial membrane potential. Importantly, C20:5 (n-3) increased the expression of PPARα and FABP5 while inhibiting NF-κB activation independently of the TLR4-IRF5 pathway. The protective effects of C20:5 (n-3) was abolished by PPARα inhibition with GW9662, indicating that C20:5 (n-3)'s action is PPARα-dependent. This study highlights the modulatory role of C20:5 (n-3) in alleviating LPS-induced oxidative stress and inflammation in macrophages through activation of the FABP5/PPARα/NF-κB axis, independently of TLR4-IRF5 signaling. These findings reveal a novel mechanism for C20:5 (n-3)'s anti-inflammatory effects and suggest that targeting the FABP5/PPARα pathway may offer therapeutic potential for treating metabolic disorders associated with chronic inflammation.</p>","PeriodicalId":19657,"journal":{"name":"Oxidative Medicine and Cellular Longevity","volume":"2025 ","pages":"3509596"},"PeriodicalIF":0.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12173550/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144317566","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}

Given the role of reactive oxygen species (ROS) in regulating platelet activation per se, we investigated the effects of a ROS scavenger on reducing the functional decline of platelet integrin <i>α</i> <sub>IIb</sub> <i>β</i> <sub>3</sub> during storage. <b>Methods:</b> Platelet-rich plasma-platelet concentrates (PRP-PCs) were either treated with ROS-reducing agents (1 mM N-acetyl-L-cysteine [NAC] or 30 μM NADPH oxidase [NOX] inhibitor, VAS2870) or kept untreated during storage.

The protective effect of mitochondria-targeted antioxidant (MTA), Mito-TEMPO coadministered at a dosage of 0.1 mg/kg b.w. i.p., was established in terms of levels/expressions of renal injury markers, histopathological alterations, oxidative DNA damage, proinflammatory markers, mtOS, mitochondrial dysfunction, and modulation of apoptotic proteins and apoptotic cell death. <b>Results:</b> A significant rise in the levels of serum urea, uric acid, and creatinine was noted after 5-FU administration to the animals. Immunohistochemical and ELISA findings demonstrated significant decrease in podocin and conversely a significant increase in neutrophil gelatinase-associated lipocalin (NGAL) expression after 5-FU challenge. The histopathological analysis further revealed Bowman's capsule dilation, glomerular condensation, and vacuolar degeneration. Mito-TEMPO treatment significantly lowered renal injury markers, reversed the expressions of podocin and NGAL to normal, and restored normal histoarchitecture of renal tissue. Mitochondrial reactive oxygen species (mtROS), mtLPO, activity of mitochondrial enzyme complexes, and mitochondrial antioxidant defense status were significantly improved in Mito-TEMPO protected group as compared to the 5-FU group. Further, significantly decreased expression of 8-OHdG, reduction in apoptotic cell death, and modulation of apoptotic proteins Bax, Bcl-2, and caspase-3 were noted in Mito-TEMPO protected group, indicating its protective effect against 5-FU-induced renal injury. <b>Conclusion:</b> The approach of targeting mtOS using MTA, Mito-TEMPO, may prove as safe adjuvant in alleviating renal toxicity during 5-FU chemotherapy.</p>","PeriodicalId":19657,"journal":{"name":"Oxidative Medicine and Cellular Longevity","volume":"2025 ","pages":"8892026"},"PeriodicalIF":0.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11986914/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144026598","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}
