Unlike most conventional ablation technologies, PEF ablation is non-thermal, allowing for safe and targeted energy delivery to the tumor without damaging surrounding tissue and critical structures. PEFs allow for specific dosing, predictable treatment zones, and preservation of the extracellular matrix and adjacent vascular tissues. Preclinical and preliminary clinical data suggest that PEF ablation may induce inflammatory changes in the tumor microenvironment (TME) that engage host innate and adaptive immune cells, stimulating an anti-tumor response. Specifically, PEF promotes local and systemic anti-tumor immune activation through immunogenic cell death and the release of damage-associated molecular patterns (DAMPs) and tumor antigens. This tumor-specific immune activation could potentially enhance response to immune checkpoint inhibitor (ICI) therapies. Furthermore, PEF ablation induces the formation of tertiary lymphoid structures (TLSs) in the TME, which are predictive biomarkers for responsiveness to ICI across several solid tumors. This combination of effects activates antigen-presenting cells and stimulates the effector T cell response, which is often inhibited in ICI-resistant cancer patients. In this review, the onco-immunological characteristics of PEF ablation are discussed, with special emphasis placed on the clinical potential of PEF ablation to induce anti-cancer immune responses and enhance responsiveness to ICI therapy in ablated and non-ablated (abscopal) tumors.</div></div>","PeriodicalId":9506,"journal":{"name":"Cancer letters","volume":"609 ","pages":"Article 217361"},"PeriodicalIF":9.1,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747506","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}

Thus, the ultimate impact of deregulated NFIB signaling is cancer-specific and strongly influenced by an intricate network of upstream regulators and downstream effectors. Deciphering the events that drive NFIB's paradoxical roles within these networks will enable us to not only understand how this critical transcription factor enacts its dual roles but also drive innovations to help us effectively target NFIB in different cancers. Here, we provide an in-depth review of NFIB. Starting with its defining role in the development of various organs, most notably the central nervous system, we highlight critical signaling pathways and the impact of deregulation on neoplastic transformation, contrasting it with the effect of silencing alone. We then provide examples of its dual roles in various cancers, identifying specific signaling networks associated with oncogenesis versus tumor suppression. We incorporate an example of a cancer type, osteosarcoma, wherein NFIB enacts its dual functions and explore which pathways influence each function. In this manner, we suggest plausible mechanisms for its role-switching from cancers sharing common triggering events in the setting of NFIB deregulation. We also review how NFIB enhances aggressiveness by driving metastasis, stemness, and chemoresistance.
