We aim to elucidate its specific mechanistic actions across endothelial cells, macrophages, and vascular smooth muscle cells (VSMCs), emphasizing its dual nature and potential as a therapeutic target.</p><p><strong>Methods: </strong>We conducted a comprehensive review of the literature to integrate mechanistic insights into 25-HC signaling pathways, their regulation by specific transcription factors, and their impact on vascular pathology.</p><p><strong>Results: </strong>25-HC exhibits a distinct biphasic dose-response. At physiological concentrations, it maintains lipid homeostasis through suppression of SREBP processing and activation of LXR signaling. However, supraphysiological accumulation induces oxidative stress, mitochondrial dysfunction, and a coordinated activation of apoptosis and autophagy, ultimately precipitating cytotoxicity. Mechanistically, 25-HC disrupts membrane lipid rafts and activates the RIG-I/MAVS axis to drive pro-inflammatory cytokine secretion (e.g., IL-8). Within the plaque microenvironment, it impairs macrophage efferocytosis by downregulating MerTK and promotes VSMC proliferation and migration via PI3K/AKT pathways. Conversely, the transcription factor KLF4 and enzymatic sulfation by SULT2B1b act as critical protective checkpoints against 25-HC-mediated toxicity.</p><p><strong>Conclusion: </strong>25-HC is not merely a biochemical byproduct but a functional determinant of plaque instability. Its impact is strictly governed by local concentration gradients and metabolic regulation. Future therapeutic strategies should focus on modulating the CH25H/KLF4 axis and promoting oxysterol sulfation to mitigate vascular inflammation and prevent atherosclerosis progression.</p>","PeriodicalId":21161,"journal":{"name":"Prostaglandins & other lipid mediators","volume":" ","pages":"107065"},"PeriodicalIF":2.5,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147373244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prostanoids, including prostaglandin E₂ (PGE₂), are well-known to play important roles in the generation of inflammatory responses. However, their excessive or prolonged activation can cause tissue damage and drive the development of diseases. Resolvin E-series (RvEs), including RvE1, RvE2, and RvE3, are specialized pro-resolving mediators that actively promote the resolution of inflammation. Here, using human macrophage-like U937 cells, we show that RvE1 and RvE2, but not RvE3, suppressed protein expression of cyclooxygenase (COX)-2, an essential and inducible enzyme involved in prostanoid synthesis during the onset of inflammatory responses. Furthermore, the suppression of COX-2 protein expression by RvE1 and RvE2 was suggested to involve enhanced ubiquitin-proteasome-dependent degradation, resulting in the rapid reduction of PGE₂ production by decreasing functional COX-2. This is the first reported evidence that RvEs exert pro-resolving effects on macrophage-associated COX-2/PGE₂ signaling. Importantly, RvEs reduced COX-2 expression at the low concentration of 10 nM without affecting COX-1 expression. Thus, they may represent promising candidates for novel anti-inflammatory drugs with potentially fewer gastrointestinal side effects than exhibited by many nonsteroidal anti-inflammatory drugs.</div></div>","PeriodicalId":21161,"journal":{"name":"Prostaglandins & other lipid mediators","volume":"183 ","pages":"Article 107064"},"PeriodicalIF":2.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146220980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
