The inactivation or downregulation of SERCA2a leads to reduced contractility in the failing heart. Here we show that SERCA2a is regulated by p22phox, a heterodimeric partner of NADPH oxidases. Endogenous p22phox was upregulated by pressure overload, but cardiac-specific p22phox knockout (cKO) in mice exacerbated heart failure, enhanced the downregulation of SERCA2a and increased oxidative stress in the SR. We show that p22phox interacts with SERCA2a, preventing its oxidation at Cys498 and subsequent degradation by the Smurf1 and Hrd1 E3 ubiquitin ligases. The exacerbation of SERCA2a downregulation and cardiac dysfunction following pressure overload in p22phox cKO mice was alleviated when these mice were crossed with SERCA2a-C498S knock-in mice, in which the oxidation-susceptible and degradation-promoting cysteine residue is mutated. Future molecular interventions to prevent the oxidation of SERCA2a at Cys498 may prevent its downregulation during heart failure. Nakada, Titus et al. show that p22phox, a heterodimeric partner of NADPH oxidases, prevents sarcoplasmic/endoplasmic reticulum Ca2+ ATPase 2a (SERCA2a) oxidation at Cys498 and its downregulation. This study suggests that therapeutic interventions to protect this residue may sustain SERCA2a expression in heart failure.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":"4 9","pages":"1187-1205"},"PeriodicalIF":10.8,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12436179/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144994610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While elevated intraocular pressure is due to impaired ocular fluid outflow through both the trabecular meshwork (TM) and the lymphatic-like Schlemm’s canal (SC) endothelium, the mechanism by which SC endothelium regulates fluid outflow in cooperation with the TM in healthy and glaucomatous conditions remains unclear. Here we create a human ocular fluid outflow on-chip, composed of a three-dimensional lymphatic or SC endothelium surrounded by TM and draining interstitial fluid. Using the system, we recapitulate steroid-induced glaucoma, characterized by decreased fluid outflow and tightened SC endothelial junctions. We further reveal that the glaucoma phenotypes are induced by an ALK5/VEGFC-mediated SC endothelial dysfunction in the presence of TM. The ocular fluid outflow on-chip provides a unique platform for bridging traditional in vitro and in vivo models of ocular lymphatic physiology and disease.

Many extracellular proteins need enzymatic activation to function, and blocking this activation is an untapped approach to restoring vessel integrity. Here we demonstrate that inhibition of the extracellular protease SKI-1 with PF-429242 restores blood vessel integrity and promotes functional recovery in both large and small animal models for stroke. Single-cell mRNA sequencing identified molecular signatures suggesting that PF-429242 restores the expression of genes involved in vessel integrity in endothelial cells. Moreover, we identify a mechanism whereby RGMa cleavage by SKI-1 is required for RGMa to interact with Neogenin and alter vessel integrity. Either preventing RGMa cleavage or deleting Neogenin on endothelial cells reduced blood vessel dysfunction, increased tissue preservation and restored brain function after stroke. This work identifies a much-needed therapeutic strategy that restores blood vessel integrity and functionality, showing efficacy in large and small animals. Shabanzadeh et al. identify and validate a pathway whereby RGMa cleavage by SKI-1 modifies gene expression related to blood–brain barrier (BBB) integrity after stroke.

Blood flow is critical for valve formation, but the cellular mechanosensors translating flow into the transcriptional regulation of valve development remain undiscovered. Here, we identify that primary cilia and blood flow in mouse embryos regulate early valve development in vivo by regionally controlling endothelial-to-mesenchymal transition (EndoMT) through the modulation of Krüppel-like factor 4 (Klf4) in the endocardial cushions. Endocardial ciliation decreases during cushion development in regions of high shear stress, correlating with KLF4 downregulation and EndoMT progression. Mouse embryos lacking cilia exhibit blood flow-dependent accumulation of KLF4 and impaired cushion cellularization. Single-nucleus RNA sequencing revealed that the cilia-knockout and contractility-knockout endocardium fails to progress through EndoMT pseudostages, retains endothelial markers, and has reduced EndoMT and mesenchymal genes that KLF4 antagonizes. These data indicate that endocardial primary cilia function as mechanosensors in cushion development through the regional regulation of KLF4. Berg et al. identify that primary cilia regulate early valve development in mouse embryos by participating in cushion development, where they function as mechanosensors regulating endothelial-to-mesenchymal transition through the modulation of Klf4.","PeriodicalId":74245,"journal":{"name":"Nature cardiovascular research","volume":"4 9","pages":"1114-1134"},"PeriodicalIF":10.8,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12436177/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144981702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genetic evidence has historically focused on IL6R missense variants, but emerging cardiovascular treatments target IL-6, not its receptor, questioning the translatability of genetic findings. Here we develop a genetic instrument for IL-6 signaling downregulation comprising IL6 locus variants that mimic the effects of the anti-IL-6 antibody ziltivekimab and use it to predict the effects of IL-6 inhibition on cardiometabolic and safety endpoints. Similar to IL6R, we found that genetically downregulated IL-6 signaling via IL6 perturbation is associated with lower lifetime risks of coronary artery disease, peripheral artery disease and ischemic atherosclerotic stroke in individuals of European and East Asian ancestry. Unlike IL6R missense variants linked to bacterial infections, the IL6 instrument was associated with lower risk of pneumonia hospitalization. Our data suggest that IL-6 inhibition can reduce cardiovascular risk without major unexpected safety concerns.
