Gelation embolism agents suppress clinical TACE-incited pro-metastatic microenvironment against hepatocellular carcinoma progression.

ABSTRACT:

Background

Current embolic agents in transcatheter arterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) encounter instability and easy leakage, discounting TACE efficacy with residual HCC. Moreover, clinical TACE aggravates hypoxia and pro-metastatic microenvironments, rendering patients with HCC poor prognosis.

Methods

Herein, we developed Zein-based embolic agents that harness water-insoluble but ethanol-soluble Zein to encompass doxorubicin (DOX)-loaded mesoporous hollow MnO₂ (HMnO₂). The conditions and capacity of HMnO₂ to generate reactive oxygen species (ROS) were assayed. Mechanical examinations of Zein-HMnO₂@DOX were performed to evaluate its potential as the embolic agent. In vitro experiments were carried o
