Abstract:

Novel albumin hybrid nanoparticles (Alb-HNPs) loaded with tyrosine kinase A (TrkA) inhibitor GNF-5837 were prepared and evaluated for antineoplastic efficacy in a panel of breast cancer cell lines. The nanomedicines (GNF-Alb-HNPs, hydrodynamic diameter ∼150nm) were formed through a unique polyelectrolyte complexation process where albumin and GNF-5837 were encapsulated by a stabilizing layer of oppositely charged chitosan and dextran sulfate polysaccharides. GNF-Alb-HNPs showed an excellent colloidal stability and a sustained drug release over more than 24h. We found that these nanomedicines inhibited TrkA phosphorylation and downstream mitogen-activated protein kinase (MAPK) signaling in breast cancer cells specifically, resulting in anti-proliferative and pro-apoptotic effects. Moreover, the migration and invasion activities of cancer cells were dramatically suppressed and the inhibitory effects were much more prominent with GNF-Alb-HNPS than the drug alone. These results show that the GNF-Alb-HNPs may represent a novel approach for targeted breast cancer therapy.
