Despite therapeutic advances, the prognosis for advanced-stage NB remains poor, necessitating improved treatment options. 4HPR has demonstrated cytotoxicity in various tumors, including NB, with low systemic toxicity; however, its clinical use is restricted by poor solubility and bioavailability. To address this, we developed a human serum albumin-based nanoformulation of 4HPR using a simple desolvation method. This formulation effectively induced apoptosis in NB cells, marked by increased ROS generation, elevated Bax/Bcl-2 ratio, and enhanced cell detachment. Notably, we identified for the first time that MAPKAPK3 downregulation leads to reduced Bax phosphorylation and increased mitochondrial translocation. Co-immunoprecipitation confirmed a direct MAPKAPK3–Bax interaction, indicating MAPKAPK3 regulates Bax via phosphorylation. Our nanoformulation modulates this cross-talk, demonstrating promising translational potential as a novel therapeutic strategy for neuroblastoma.</div></div>","PeriodicalId":19050,"journal":{"name":"Nanomedicine : nanotechnology, biology, and medicine","volume":"70 ","pages":"Article 102858"},"PeriodicalIF":4.6,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145113875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Persistent oxidative stress (OS), primarily caused by high levels of reactive oxygen species (ROS), can directly activate hepatic stellate cells, induce hepatocyte apoptosis and trigger inflammatory responses. We modified the surface of silymarin (SIL)-carrying liposomes with catalase (CAT) to treat liver fibrosis. CAT is an endogenous antioxidant enzyme that is primarily responsible for removing hydrogen peroxide generated by oxidative stress. SIL is a traditional liver-protective dietary supplement. In vitro experiments showed that CAT-LP exhibited low cytotoxicity towards normal hepatocytes (L-02 cells) and could be effectively taken up by hepatic stellate cells (JS1 cells), inducing apoptosis. Additionally, CAT-LP effectively alleviated TGF-β-induced oxidative stress by scavenging ROS, demonstrating more complete release in an H₂O₂-enriched environment. In vivo experiments revealed that CAT-LP treatment significantly reduced malondialdehyde (MDA) and transaminase (ALT and AST) levels, increased superoxide dismutase (T-SOD) content and reduced the secretion and deposition of type III procollagen.

Traditional injectable drug therapies, while effective, have limitations such as systemic side effects, low patient compliance, and inefficient drug delivery to the wound site. Nanoparticle-infused wound dressings offer a promising alternative by providing localized, sustained drug release while enhancing the wound healing process. These advanced dressings integrate nanoparticles (NPs) such as metallic, polymeric, lipid-based, and hydrogel-based systems to improve antimicrobial activity, promote angiogenesis, and facilitate tissue regeneration. Nanoparticles enable controlled drug release, protect bioactive agents from degradation, and enhance penetration into deeper wound layers, making them highly effective for chronic wounds like diabetic ulcers, burns, and surgical incisions. Moreover, functionalized NPs can incorporate antimicrobial agents, growth factors, and anti-inflammatory compounds, significantly reducing infection risks and promoting faster healing. Emerging studies highlight the potential of silver, gold, chitosan, and lipid-based NPs in improving wound care outcomes compared to conventional approaches. This review provides a comprehensive analysis of various nanoparticle-based wound dressings, their mechanisms of action, and their advantages over injectable therapies. It also discusses the challenges in clinical translation, including biocompatibility, regulatory hurdles, and large-scale production. With continuous advancements in nanomedicine, nanoparticle-infused wound dressings hold immense potential to revolutionize wound management, offering a patient-friendly and efficient alternative to traditional treatments.
