Cancer cell membrane-camouflaged MOF nanoparticles for a potent dihydroartemisinin-based hepatocellular carcinoma therapy.

ABSTRACT: Developing new drugs for cancer treatment remains a challenging task. Herein, cancer cell membrane biomimetic ferrous ion-doped metal-organic framework nanoparticles (ZIF-8 nanoparticles) combined with dihydroartemisinin (DHA) have been designed for targeted cancer treatment with low toxicity and side effects. The biomimetic nanomaterials (CDZs) have excellent homologous targeting ability and can accumulate in tumor tissues. In an acid tumor microenvironment, ferrous ions and DHA could be released with the degradation of materials. DHA, an ancient Chinese medicine, combines with ferrous ions to produce a powerful anti-tumor effect. In human liver cancer models, about 90.8% of tumor growth was suppressed. In addition, the nanomaterial has no obvious toxic and side effects in vivo and is a highly effective and low-toxicity anti-tumor drug with a strong clinical application value.

Project description:Background:Melanoma is the most common symptom of aggressive skin cancer, and it has become a serious health concern worldwide in recent years. The metastasis rate of malignant melanoma remains high, and it is highly difficult to cure with the currently available treatment options. Effective yet safe therapeutic options are still lacking. Alternative treatment options are in great demand to improve the therapeutic outcome against advanced melanoma. This study aimed to develop albumin nanoparticles (ANPs) coated with macrophage plasma membranes (RANPs) loaded with paclitaxel (PTX) to achieve targeted therapy against malignant melanoma. Methods:Membrane derivations were achieved by using a combination of hypotonic lysis, mechanical membrane fragmentation, and differential centrifugation to empty the harvested cells of their intracellular contents. The collected membrane was then physically extruded through a 400 nm porous polycarbonate membrane to form macrophage cell membrane vesicles. Albumin nanoparticles were prepared through a well-studied nanoprecipitation process. At last, the two components were then coextruded through a 200 nm porous polycarbonate membrane. Results:Using paclitaxel as the model drug, PTX-loaded RANPs displayed significantly enhanced cytotoxicity and apoptosis rates compared to albumin nanoparticles without membrane coating in the murine melanoma cell line B16F10. RANPs also exhibited significantly higher internalization efficiency in B16F10 cells than albumin nanoparticles without a membrane coating. Next, a B16F10 tumor xenograft mouse model was established to explore the biodistribution profiles of RANPs, which showed prolonged blood circulation and selective accumulation at the tumor site. PTX-loaded RANPs also demonstrated greatly improved antitumor efficacy in B16F10 tumor-bearing mouse xenografts. Conclusion:Albumin-based nanoscale delivery systems coated with macrophage plasma membranes offer a highly promising approach to achieve tumor-targeted therapy following systemic administration.
