Does Gold-Silver Core-Shell Nanostructure with Alginate Coating Induce Apoptosis in Human Lymphoblastic Tumoral (Jurkat) Cell Line?

Background: T-cell acute lymphoblastic leukemia (T-ALL) is known as an aggressive malignant disease resulting from the neoplastic alteration of T precursor cells. Although treatment with stringent chemotherapy regimens has achieved an 80% cure rate in children, it has been associated with lower success rates in adult treatment. Silver nanoparticles (Ag-NPs) have a toxic effect on human breast cancer cells, human glioblastoma U251 cells, and chronic myeloid leukemia cells in vitro. This study aimed to investigate the effect of Ag nanostructures (Ag-NSs) on Jurkat cells’ viability and apoptosis. Methods: The Jurkat cell line was acquired. Following the synthesis Ag-NSs and their characterization, they were incubated with Jurkat cells at different doses for 24, 48, and 72 hours to determine the optimal time and dose. Two groups were examined: a control group with Jurkat cells without nanostructure maintained in the same medium as the cells in the treatment group without changing the medium, and a treatment group with cells treated with the Ag nanostructure solution at a dose of 75 µg/ml for 48 hours according to the MTT results. After 48 hours, the cells from the two groups were used for the q RT-PCR of the apoptotic genes (BAX, BCL-2, and CASPASE-3). Results: According to our results, the rod-shaped silver nanostructures had a size of about 50 nm, increased apoptotic markers, including BAX and CASPASE-3, and induced cell death. Conclusions: Ag-NSs have anticancer properties and can induce apoptosis of cells; therefore, they may be a potential candidate for the treatment of T-cell acute lymphoblastic leukemia.
