Purpose: Hepatocellular carcinoma (HCC) is one of the most common fatal cancers, with no curative therapy available. The concept of ferroptosis is attracting increasing attention in cancer research. Herein, we describe the use of a nanodevice as an effective strategy for inducing ferroptosis to manage HCC.
Methods: To improve ferroptosis-induced treatment of HCC, we constructed sorafenib (sor)-loaded MIL-101(Fe) nanoparticles (NPs) [MIL-101(Fe)@sor] and evaluated the efficacy of ferroptosis-based HCC therapy after co-administration with the iRGD peptide both in vitro and in vivo.
Results: The prepared MIL-101(Fe) NPs have several promising characteristics including drug-loading, controllable release, peroxidase activity, biocompatibility, and T2 magnetic resonance imaging ability. MIL-101(Fe)@sor NPs significantly induced ferroptosis in HepG2 cells, increased the levels of lipid peroxidation and malondialdehyde, and reduced those of glutathione and glutathione peroxidase 4 (GPX-4). The in vivo results showed that the MIL-101(Fe)@sor NPs significantly inhibited tumor progression and decreased GPX-4 expression levels, with negligible long-term toxicity. Meanwhile, co-administration of MIL-101(Fe)@sor NPs with iRGD significantly accelerated ferroptosis.
Conclusion: Our findings suggest that MIL-101(Fe)@sor NPs co-administered with iRGD are a promising strategy for inducing HCC ferroptosis.
