However, the role of nitric oxide (NO) in causing Fe<sup>2+</sup> overload for ferroptosis remains uncertain. This study reveals that NO can stimulate endogenous Fe<sup>2+</sup> release by upregulating heme oxygenase 1 (HMOX1) expression. Here, ferritin heavy chain (FHC) siRNA and hyaluronic acid (HA)-modified Arg-stabilized zinc peroxide (AZOSH), a non-ferrous-based nanoagent, is synthesized to trigger ferroptosis by inducing intracellular Fe<sup>2+</sup> overload. AZOSH, a self-catalyzed NO nanocomplex, effectively generates NO through a reaction of self-supplied Arginine (Arg) and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), which promotes glutathione (GSH) consumption to downregulate glutathione peroxidase 4 (GPX4) expression and produces peroxynitrite (ONOO<sup>-</sup>) to enhance LPO. Meanwhile, NO promotes endo/lysosomal escape of siRNA by damaging membrane structures. Moreover, AZOSH significantly triggers Fe<sup>2+</sup> overload through the synergistic effects of NO-activated HMOX1 expression and FHC siRNA-mediated ferritin sequestration. Additionally, the released Zn<sup>2+</sup> from AZOSH induces oxidative stress by inhibiting mitochondrial function, further promoting ferroptosis. Consequently, AZOSH-mediated ferroptosis exhibits a strong cellular immunogenic response for T-cell activation and infiltration. Importantly, the integration of AZOSH with an anti-PD-1 antibody results in notable antitumor efficacy in vivo. Therefore, this study provides a novel concept of NO-induced ferroptosis, highlighting its role in enhancing PD-1-based immunotherapeutic efficacy.</p>","PeriodicalId":15450,"journal":{"name":"Journal of Controlled Release","volume":" ","pages":""},"PeriodicalIF":10.5,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142695547","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}

Improved formulations promoting a more rapid absorption would increase convenience of use but requires a faster onset of action. We have developed a salcaprozate-based ionic liquid (IL) formulation, namely choline salcaprozate (CHONAC), for oral delivery of a glucagon-like peptide-1 (GLP-1) analogue <em>via</em> gastric absorption. <em>In vitro</em> studies confirmed the higher amount of PE accommodated in the same volume of dosage form as well as faster release of the active pharmaceutical ingredient (API) and PE compared to the tablet reference. Storage stability of the CHONAC formulation was demonstrated for up to 3 weeks at 4 °C. The peptide absorption efficacy of the IL formulation was first evaluated <em>in vivo</em> in rats and anesthetized dogs, showing a faster absorption compared to the reference formulations. In awake dogs, while the CHONAC formulation still enabled earlier API absorption, its overall exposure was inferior to the tablet reference. This was attributed mostly to the gastric physiology, causing formulation dilution in the presence of additional fluid as well as fast transit of liquids into the duodenum, where peptides liable to proteolytic degradation such as the one used in this study showed a negligible absorption, potentially also due to a lower permeation-enhancing capability of CHONAC in the duodenal region. Exploring these issues, an <em>in vivo</em> study in anesthetized dogs involving repeated dosing of a liquid salcaprozate-based formulation in the stomach revealed the potential to sustain peptide absorption throughout the dosing period with a constant absorption rate. In conclusion, combining the advantages of high PE amounts and fast onset of action provided by the IL formulation, and ensuring a prolonged interaction of peptide and PE at a relevant concentration with the stomach epithelium, are necessary to enhance oral peptide bioavailability <em>via</em> gastric delivery.","PeriodicalId":15450,"journal":{"name":"Journal of Controlled Release","volume":"1 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678559","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}
