Drug-Carrying Capacity and Anticancer Effect of the Folic Acid- and Berberine-Loaded Silver Nanomaterial To Regulate the AKT-ERK Pathway in Breast Cancer
2018
Currently, in clinics, breast cancer is treated with free chemotherapeutic drugs, as a result there is not much therapeutic effect in treated models, leading to substantial systemic toxicity. To overcome these critical problems for the primary outcome, we developed the formulated nanomaterial (FA-PEG@BBR-AgNPs) aimed to specifically target cancer cells via nanoscopic-based drug delivery for getting better therapeutic effectiveness. In the present study, an isoquinoline alkaloid, berberine (BBR), was chosen as a cancer therapeutic agent, encapsulated on citrate-capped silver nanoparticles (AgNPs) through electrostatic interactions (BBR-AgNPs). Then, BBR-AgNPs were conjugated with polyethylene glycol-functionalized folic acid (FA-PEG) via hydrogen bonding interactions (FA-PEG@BBR-AgNPs). The transmission electron microscopy study shows the cellular invasion of the formulated FA-PEG@BBR-AgNPs, indicating the accretion of the nanomaterial at the tumor-specific site. Hence, FA conjugated with the nanomaterial ...
