Ferric Oxide Nanoparticles Enhance Cytotoxicity and Reduce the Occurrence and Development of Cervical Cancer Metastases
Fe3O4 nanoparticles can be used in diagnostic imaging and therapeutic applications. However, poor solubility limits its use in tumors. In this study, we used ferric oxide and nanoparticles to covalently bind ferric oxide nanoparticles as a strategy for treatment
of cervical cancer metastases. We aimed to evaluate their biological effects on cervical cancer metastases in vivo. Confocal microscopy was used to detect transfection efficiency, ferric oxide or ferric oxide nanoparticles were used to intervene cervical cancer cell lines, and flow
cytometry explored cell apoptosis. The mouse model of cervical cancer metastasis was further treated with ferric oxide or ferric tetroxide nanoparticles through intraperitoneal injection. The tumor volume was counted and size was measured. Cell proliferation and apoptosis were detected by
IHC and Western-blot was used to detect protein expression. Nanoparticles significantly enhanced the cellular uptake of Fe3O4, which inhibited cell proliferation and promoted cell apoptosis. In the in vivo transplanted tumor model, the same was observed in mice.
In the mice model, ferric oxide nanoparticles significantly inhibited the growth of tumors, slowed down tumor growth rate, and accelerated apoptosis. Our research results showed that nanoparticles contributed to the uptake of oxidized particles, and Fe3O4 nanoparticles
regulated studied tumors by enhancing cytotoxicity, thereby inhibiting cell proliferation and promoting cell apoptosis, achieving Fe3O4 nanoparticles. The particles significantly inhibited tumor growth, slowed down multiplication rate, and accelerated apoptosis, suggesting
that Fe3O4 nanoparticles have a significant inhibitory effect on cervical cancer transplanted tumors.
期刊介绍:
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
