A Paradigm Shift in Tumor Treatment
Cancer remains a formidable challenge to global health, necessitating innovative approaches to enhance diagnostic precision and therapeutic outcomes. Among these, tumor microenvironment-responsive treatments have emerged as a promising frontier. This study presents a novel enzymatic/Fenton nanoreactor, leveraging Fe-based metal-organic frameworks (MOFs) loaded with glucose oxidase (GOx) and perfluoropentane (PFP), termed PGPMs. By integrating tumor-targeted imaging with advanced therapeutic mechanisms, PGPMs aim to address critical obstacles in current cancer therapies, such as inefficient Fenton catalytic activity and tumor hypoxia.
Harnessing Nanotechnology for Precise Therapeutics
This research investigates the hypothesis that incorporating Fe2+/Fe3+ MOFs with GOx and PFP can significantly enhance tumor imaging and therapeutic capabilities. The study aims to validate this nanoreactor’s ability to generate reactive oxygen species (ROS), improve imaging modalities, and suppress tumor growth while maintaining biosafety. By addressing limitations in traditional Fenton reagents and exploring the dual-modality imaging potential, the work seeks to establish a comprehensive cancer theragnostic platform.
Engineering the Future of Cancer Diagnostics and Therapy
The development of PGPMs begins with a one-pot synthesis of Fe2+/Fe3+-based MOFs, followed by the encapsulation of GOx and PFP. Theoretical foundations draw on the enhanced catalytic properties of Fe2+ and GOx-induced glucose metabolism, which amplify ROS production. Methodological rigor is maintained through advanced imaging techniques (ultrasound and magnetic resonance imaging), in vitro enzymatic assays, and in vivo experiments with 4T1 tumor-bearing mice models. The study also incorporates flow cytometry, confocal microscopy, and biochemical analyses to ensure a robust evaluation of the nanoreactor’s capabilities.
