TL;DR
This study shows that Mg-doped copper ferrite nanoparticles can effectively kill cancer cells by inducing apoptosis and DNA damage.
Contribution
The novel contribution is the synthesis and evaluation of Mg-doped CuFe2O4 nanoparticles with optimized properties for anticancer activity.
Findings
Cu0.5Mg0.5Fe2O4 showed the highest cytotoxicity with IC₅₀ values of 17.2 µg/mL and 25.04 µg/mL against PC-3 and Caco-2 cells.
The nanoparticles induced significant apoptosis (42.08% in PC-3 and 34.95% in Caco-2 cells) through ROS-mediated pathways.
Gene expression changes indicated mitochondrial-dependent apoptosis via BAX, P53, and Caspase-3 upregulation and Bcl-2 downregulation.
Abstract
Ferrite nanoparticles (NPs) have emerged as promising candidates for cancer therapy. In this study, Mg-doped copper ferrite NPs, MgₓCu₁₋ₓFe2O4 (x = 0.0, 0.5, and 1.0), were synthesized via a citrate–nitrate combustion method and evaluated for their anticancer potential. Structural and morphological characteristics were analyzed using powder X-ray diffraction, field-emission scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Cytotoxicity against human cancer cell lines was assessed using MTT and flow cytometry assays, along with analyses of reactive oxygen species (ROS) generation and apoptosis. Among the compositions studied, Cu0.5Mg0.5Fe2O4 demonstrated the highest cytotoxic efficacy, with IC₅₀ values of 17.2 ± 0.15 µg/mL (PC-3) and 25.04 ± 0.28 µg/mL (Caco-2). Flow cytometric analysis revealed increased total apoptosis of 42.08% and 34.95% in PC-3 and Caco-2…
