The silver nanoparticles (AgNPs) are widely used in cancer treatment and several other biomedical applications.Objective: The study aimed to determine the effects of silver citrate nanoparticles (AgNPs-CIT) on NF-κB activation together with TNFα mRNA/protein expressions in the phorbol myristate acetate (PMA)-stimulated MCF-7 human breast cancer cell-lines.Methods: The AgNPs-CIT were synthesized by the reduction method, and the prepared AgNPs-CIT were characterized for their shape, absorption in UV-VIS electromagnetic radiations, size distribution, ζ-potential, and antioxidant activity. The MCF-7 cell-lines were pretreated with AgNPs-CIT and stimulated with PMA. The TNFα mRNA expressions were determined by real-time PCR, whereas the protein production was determined by the ELISA. The NF-κB activity was distinctly observed by highly-specific DNA-based ELISA, and by NF-κB-specific inhibitor, Bay 11– 7082.Results: The prepared AgNPs-CIT were spherical and have an absorption wavelength range of 381– 452 nm wherein the particles size ranged between 19.2± 0.1 to 220.77± 0.12 nm with the charge range − 9.99± 0.8 to − 34.63± 0.1 mV. The prepared AgNPs-CIT showed comparative antioxidant activity at > 40% inhibitions level of the DPPH radicals. The AgNPs-CIT were found to be non-toxic to MCF-7 cell-lines and inhibited PMA-induced activation of the NF-κBp65, and also the mRNA/protein expression of TNFα.Conclusion: This is the first report that showed AgNPs-CIT inhibited TNFα expression via deactivation of the NF-κB signaling event in stimulated breast cancer cells. The results have important implications for the development of novel therapeutic strategies for the prevention/treatment of cancers and/or inflammatory disorders.Keywords: phorbol myristate acetate, PMA, TNFα, NF-κB, silver citrate nanoparticles, MCF-7 cell lines, cancer, inflammatory cytokines |
