| Summary: | Abstract Breast cancer ranks as the second leading reason of cancer mortality among females globally, emphasizing the critical need for novel anticancer treatments. In current work, berberine-zinc oxide conjugated chitosan nanoparticles were synthesized and characterized using various characterization techniques. The cytotoxic effects of CS-ZnO-Ber NPs on MCF-7 cells were assessed using the MTT assay. Also, annexin V-FITC/PI double staining, Hoechst 33,342 staining, caspases-8 and 9 activity assays, and cell cycle analysis were performed. Furthermore, the mRNA levels of Bax and Bcl-2 genes were quantified using qPCR. Additionally, cell migration was evaluated using a scratch assay. The IC50 value of NPs against MCF-7 cells measured 7.41 µg/mL. Apoptosis induction in NP-treated cells was confirmed by Annexin V/PI staining, accompanied by the observation of condensed chromatin and fragmented DNA. Moreover, the pro-apoptotic potential of NPs was evidenced by significant increases in caspases-8 and 9 activity and a decreased Bcl-2/Bax ratio. Furthermore, cell cycle arrest at the sub-G1 was noticed in the treated cells. Additionally, the NPs markedly inhibited the migration rate of MCF-7 cells. These findings suggest that CS-ZnO-Ber NPs induce cell-cycle arrest and activate the apoptotic pathways in MCF-7 cells, highlighting their potential as a hopeful therapeutic agent for breast cancer. |
