Cellular Metabolic Responses to Copper Nanoparticles: Comparison Between Normal and Breast Cancer Cells.

ABSTRACT: The use of copper nanoparticles (CuNPs) seems to be an alternative therapeutic strategy for cancer therapy due to low-cost synthesis and anticancer activity. In this work, CuNPs' effects were tested in various concentrations on two types of cells: mesenchymal stem cells (MSCs) and a breast cancer cell line, SKBR3. The concentrations (0.25 mM, 0.5 mM, 1 mM and 2 mM) were first tested on an impedance-based cytotoxicity assay and then used in further cellular metabolic assays. Next, several techniques were applied to test the chosen concentrations: assessment of apoptosis, intracellular reactive oxygen species (ROS) levels, oxidative stress-related gene expression, assessment of mitochondrial respiration and fatty acid methyl ester (FAME) profile evaluation. The higher CuNP concentrations tes
