This is a proof-of-concept study describing the rational design and in vitro characterization of a dual-responsive nanoplatform combining glucose oxidase-mediated starvation therapy with iron-catalysed chemodynamic therapy to promote ferroptosis in endometrial cancer cells. The work establishes a synthetic framework but provides no quantitative efficacy data, animal model validation, or clinical evidence to support therapeutic translation.
In vitro mechanistic study. HEC-1A endometrial cancer cell line. Intervention: GOD-Fe3+&DOX-Membrane@Polymer nanoplatform constructed via RAFT polymerization with pyridine disulfide bonds and benzylboronic acid moieties.
Nanoplatform incorporates pyridine disulfide bonds and benzylboronic acid for covalent immobilization of glucose oxidase and reversible borate ester linkage to cancer cell membranes GOD-mediated glucose consumption produces H2O2, which is converted to hydroxyl radicals via Fe3+-catalysed Fenton reaction Cascade reaction proposed to amplify tumour oxidative stress and initiate ferroptosis in HEC-1A cells

This is a discovery-stage nanoformulation report with no efficacy metrics, animal efficacy data, or clinical translation pathway described. Clinicians and researchers should view this as early-stage synthetic chemistry and cell biology, not as evidence for therapeutic development.
This is an early-stage in vitro study of a novel nanoplatform design using cell lines with no animal or clinical data, demonstrating proof-of-concept for a synthetic construct but lacking the rigor needed to assess clinical utility.

Abstract Endometrial cancer is a common malignant tumor in the female reproductive system. Traditional chemotherapy has limitations such as poor targeting, dose-limiting toxicity, and treatment intensity restrictions. To address these issues, this study constructed an intelligent nanoplatform–GOD-Fe3+&DOX-Membrane@Polymer (GOD-Fe3+&DM@Poly.)–based on reversible addition-fragmentation chain transfer (RAFT) polymerization technology. The incorporation of pyridine disulfide bonds as polymer side chains through RAFT polymerization facilitated the precise covalent immobilization of glucose oxidase (GOD), effectively mitigating the leakage issues commonly observed with physical encapsulation methods. Concurrently, benzylboronic acid moieties were integrated into the polymer backbone, enabling the formation of reversible borate ester linkages with sialic acid residues present on the membranes of HEC-1A cancer cells. This interaction promoted homologous targeting and substantially improved their intratumoral enrichment efficiency. In addition, GOD-mediated starvation therapy and Fe3+-triggered chemodynamic therapy construct a cascade reaction: GOD consumes tumor glucose to produce H2O2, which is converted into highly toxic hydroxyl radicals through the Fe3+-mediated Fenton reaction, amplifying tumor oxidative stress to initiate ferroptosis. This integration establishes a valuable technical framework for the development of multifunctional and stimuli-responsive nanomedicines.
