{"title":"Fatty acid synthase in cardiovascular disease: from molecular mechanisms to therapeutic targeting","authors":"Dina Ibrahim, Mohamed S Zaghloul, Bera Koklu, Abdullah Elahi, James L Januzzi, Marc P Bonaca, Mohamed A Zayed","doi":"10.1093/cvr/cvag200","DOIUrl":"https://doi.org/10.1093/cvr/cvag200","url":null,"abstract":"Fatty acid synthase (FAS), the rate-limiting enzyme of de novo lipogenesis, is now recognized as a multifunctional regulator of cardiovascular homeostasis; its roles extend beyond simple FA biosynthesis to encompass calcium signaling, cholesterol trafficking, and inflammatory modulation. This review synthesizes current understanding of FAS molecular biology, tissue-specific expression, and pathophysiological contributions to cardiovascular disease. Circulating FAS (cFAS) associates with lipoproteins and promotes macrophage foam cell formation independently of low-density lipoprotein cholesterol concentration, establishing a novel atherogenic mechanism. cFAS is primarily hepatic in origin and is released under conditions of enhanced de novo lipogenesis and insulin resistance. Adipose tissue may also contribute through extrusion of FAS. In macrophages, Fasn deletion enhances cholesterol efflux through liver X receptor alpha induction and ATP-binding cassette transporter A1 upregulation, reducing atherosclerosis by 20-40% in preclinical models without affecting serum lipids. Vascular smooth muscle cells upregulate FAS during phenotypic switching, facilitating transformation into foam cells within plaques. Clinical studies have established cFAS as a diagnostic biomarker for peripheral arterial disease, with higher concentrations present in affected individuals; elevated cFAS may also discriminate more severe disease. Despite its pathogenic roles in atherosclerosis, cardiac FAS serves essential stress-adaptive functions through calcium/calmodulin-dependent protein kinase II regulation, as cardiac-specific Fasn knockout mice exhibit profound stress intolerance and accelerated aging-related cardiac dysfunction, demonstrating that FAS-mediated de novo lipogenesis is indispensable for myocardial stress responses. This observation necessitates tissue-specific therapeutic approaches. Pharmacological FAS inhibitors, including TVB-2640 (denifanstat), demonstrate acceptable safety profiles in clinical trials and reduce hepatic de novo lipogenesis by 50-70%, while platensimycin reduces atherosclerotic burden in preclinical models. These findings position FAS as both a mechanistic driver and promising therapeutic target for cardiovascular disease. However, the divergent consequences of FAS modulation across tissues underscore the need for targeted delivery strategies that suppress pathological lipogenesis while preserving essential cardiac functions.","PeriodicalId":9638,"journal":{"name":"Cardiovascular Research","volume":"78 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148946721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These meta-analyses showed that murine and human plaque fibroblast identity was robustly defined by Pdgfra, Pi16, Cygb, and Serpinf1 mRNA. Ninety-five percent of plaque fibroblasts do not derive from the Myh11 lineage, while no Cdh5-lineage-positive cells were present in the fibroblast cluster. We identified five murine arterial fibroblast subsets in atherosclerotic murine aorta: progenitor fibroblasts, matrix fibroblasts, inflammatory fibroblasts, an EC-like fibroblast subset, detected in both adventitia and plaques, and Col5a3+ fibroblasts, unique to the adventitia. We next studied fibroblast identity, origin, and fate using pseudotime analysis and Pdgfra-CreERT2/tdTomato lineage reporter mice (Pdgfra Lin+).

The mechanosensitive calcium channels, PIEZO1 and PIEZO2, regulate cellular responses to a variety of mechanical conditions; however, PIEZO1 and PIEZO2 have not been studied in MR. We investigated the hypothesis that PIEZO1 and PIEZO2 mediate, through 5-HT mechanisms both homeostasis in normal mitral valves (nMV) and in the pathophysiology of MR. Methods and Results Immunofluorescence and Western blots demonstrated the presence of PIEZO1 and PIEZO2 in samples of explanted human nMV and MR. MVIC derived from nMV and MR leaflets also expressed PIEZO1 and PIEZO2. Single-cell RNA sequencing (scRNA-seq) analyses of nMV and MR leaflet samples from 9 MR and 5 nMV cases identified 7 different cell types: Endothelial cells, smooth muscle cells, T-cells, macrophages, and three distinct MVIC phenotypes, VIC1, VIC2, and VIC3. MVIC together comprised 97% of all valve cells, irrespective of valve pathology. In addition, scRNA-seq of nMV and MR leaflets demonstrated MVIC PIEZO1 and PIEZO2 expression, together with HTR2B and SLC6A4. MVIC cultures, with no added 5-HT, demonstrated that PIEZO1 activation with its agonist, Yoda1, increased MVIC Ca2+ uptake. This was inhibited by PIEZO1-siRNA, and Dooku1, a Yoda1 antagonist, but not PIEZO2-siRNA or noncoding-RNA. Additional MVIC studies revealed that in static MVIC cultures, PIEZO1 activation with Yoda1 downregulated SLC6A4, upregulated HTR2B, and increased 5-HT levels and protein synthesis. Cyclic tension MVIC bioreactor studies showed that either PIEZO1-siRNA or PIEZO2-siRNA mitigated tension induced SLC6A4 downregulation and increased collagen synthesis; only PIEZO2-siRNA mitigated both static and cyclic tension-induced MVIC 5-HT production.

Methods and Results In 40,829 UK Biobank participants (free-of-CAD, baseline-365 days thereafter; 55% women; mean age 56.9 ± 8.1 years), we examined associations between 2,922 plasma proteins and incident CAD over a median follow-up of 13.7 years (IQR 13.1-14.4) using multivariable-adjusted Cox proportional hazards models. Sex-specific analyses identified 440 female exclusive and 32 male exclusive proteins associated with incident CAD (FDR-corrected p &lt; 0.05), revealing distinct pathway enrichments, including innate immune response in women and angiogenesis in men. Causality was assessed through combined and sex-stratified two-sample Mendelian randomization (MR) using inverse-variance-weighted analyses with genome wide association summary statistics from 422,108 men (61,969 cases) and 521,695 women (27,128 cases) (UK Biobank, FinnGen freeze 9).
