Poly(Epsilon-Lysine) Dendrons Inhibit Proliferation in HER2-Overexpressing SKBR3 Breast Cancer Cells at Levels Higher than the Low-Expressing MDA-MB-231 Phenotype and Independently from the Presentation of HER2 Bioligands in Their Structure.

Abstract excerpt

Among the known breast cancers, the subtype with HER2 receptors-overexpressing cells is associated with a poor prognosis. The adopted monoclonal antibody Trastuzumab has improved clinical outcomes, but it is associated with drug resistance and relatively high costs. The present work adopted the peptide solid-phase synthesis method to synthesise branched poly(ε-lysine) peptide dendrons with 8 branching arms...
