Despite extensive research aimed at enhancing the understanding of their intracellular behavior and the potential genomic side effects of nanoparticles, scientists have paid relatively little attention to nanoparticle-induced epigenetic changes. This oversight is surprising given the critical role of epigenetic mechanisms in shaping cellular function and destiny. Epigenetic mechanisms include the procedures that modulate DNA or RNA and influence the production of proteins as well as the extent to which they are produced. Each cell type demonstrates unique epigenetic profiles. Epigenetic changes can disrupt normal cellular functions, potentially leading to devastating outcomes. Investigating how nanoparticles impact these epigenetic mechanisms provides valuable insights into their safe and effective use in medical applications. This review provides a detailed overview of how nanoparticles enter cells and the impact of nanoparticles on epigenetic mechanisms, focusing on current related studies on different types of cells.</p>","PeriodicalId":7284,"journal":{"name":"Advanced Therapeutics","volume":"8 6","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current therapeutic landscape for metastatic OS is limited by the lack of effective targeted therapies. Here, the development and preclinical evaluation of a novel CD24 antibody-drug conjugate (ADC) designed for the targeted ablation of primary OS tumors and pulmonary metastases are reported. An unbiased, quantitative screening of cancer-related cell surface markers on human OS cells identifies CD24 as a novel target for ADC therapy in OS, owing to its disease-specific overexpression and rapid antigen-mediated internalization. Based on these findings, a proof-of-concept ADC, comprising a humanized CD24 antibody conjugated with mertansine (CD24-DM1), was designed and constructed. CD24-DM1 demonstrated potent cytotoxicity against a panel of human OS cell lines while sparing normal human osteoblasts. In an orthotopic OS model, CD24-DM1 induced complete and durable tumor regression. Additionally, CD24-DM1 significantly delayed tumor growth in a lung-metastatic OS model, providing robust in vivo evidence of CD24 as a promising ADC target for OS therapy. In conclusion, CD24-DM1 exhibits a favorable therapeutic index for the treatment of metastatic OS in preclinical models, highlighting its potential as an effective targeted therapeutic option.</p>","PeriodicalId":7284,"journal":{"name":"Advanced Therapeutics","volume":"8 6","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, alternatives to standard antibiotic therapies have been highly sought after to address difficult-to-treat biofilm-associated infections. A biomaterial-based approach using the innate functions of mucins is hypothesized to modulate bacterial surface attachment and virulence can provide a new therapeutic strategy against biofilms. Based on the testing in <i>Pseudomonas aeruginosa</i> biofilms, it is found that synthetic mucus biomaterials can inhibit biofilm formation and significantly reduce the thickness of mature biofilms. In addition, if synthetic mucus biomaterials can work synergistically with DNase and/or α-amylase for enhanced biofilm dispersal is evaluated. Combination treatment with these antibiofilm agents and synthetic mucus biomaterials resulted in up to 2 log reductions in the viability of mature <i>P. aeruginosa</i> biofilms.
