Unveiling the therapeutic potential of anthocyanin/cisplatin-loaded chitosan nanoparticles against breast and liver cancers
2024
Overview
BackgroundLiver and breast cancers are among the leading causes of cancer-related deaths worldwide, prompting researchers to seek natural anticancer agents and reduce chemotherapy side effects. Red beetroot (Beta vulgaris Linnaeus), rich in polyphenols and powerful antioxidants, has shown potential in cancer prevention. This study aimed to evaluate the impact of red beetroot-derived anthocyanin (Ant), Ant-loaded chitosan nanoparticles (Ant NPs), cisplatin (Cis), Cis-loaded chitosan (Cis NPs), and Cis + Ant-loaded chitosan NPs on human hepatoma HepG2 and breast adenocarcinoma MCF7 cell lines.MethodsNPs preparation was evaluated by zeta potential, FTIR, and SEM. The cytotoxic, apoptotic, antioxidant, anti-inflammatory, anti-metastatic, and anti-angiogenic effects were assessed by MTT assay, qPCR, AO/EB staining, and flow cytometry.ResultsTreatment with Ant, Ant NPs, Cis, Cis NPs, and Cis + Ant NPs caused cytotoxicity in HepG2 and MCF7 with best effect in Cis-treated cells. The anticancer effects were attributed to mitochondrial-dependent apoptosis (with high Bax and low Bcl2 expression), chromatin disintegration, and cell cycle arrest in G2/M and S phases. All treatments inhibited migration by downregulating the migration-related gene MMP9 and upregulating the anti-migratory gene TIMP1 and decreased the angiogenesis-related gene VEGF and the inflammatory gene TNFα with best results in Cis NPs-treated cells. Interestingly, Ant, Ant NPs, and Cis + Ant NPs increased the antioxidant status (high GSH and upregulated expression of Nrf2 and OH-1) and decreased drug resistance-related MAPK1 and MDR1 genes compared to Cis and Cis NPs-treated cells.ConclusionsAnthocyanin and cisplatin-loaded chitosan nanoparticles effectively combat breast and liver cancers by inducing cancer cell apoptosis, enhancing antioxidant defenses, and reducing inflammation. They also inhibit tumor spread and blood vessel formation through downregulation of MMP9 and VEGF, highlighting their therapeutic potential.
