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.</p><p><strong>Methods: </strong>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 (<i>BAX</i>, <i>BCL-2</i>, and <i>CASPASE-3</i>).</p><p><strong>Results: </strong>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.</p><p><strong>Conclusions: </strong>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.</p>","PeriodicalId":45319,"journal":{"name":"Reports of Biochemistry and Molecular Biology","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10838595/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139693090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
