| Outline of Final Research Achievements |
To assess therapeutical implications of the necrosis-inducing agents for cancer treatment, we developed a neuropilin-1 (NRP-1)-targeted hybrid peptide, which induces non-apoptotic cell death against lung and breast cancer cells. We determined that the mode of cell death induced with the peptide is similar to necrosis. siRNA knockdown of NRP-1 on A549 cells significantly reduced cytotoxicity of the hybrid peptide. Also, treatment of the hybrid peptide on A549 cells lead to the extracellular release of a necrotic marker protein high mobility group B-1. The peptides will be a useful tool for development of novel concept-based anti-tumor agents such as a necrosis-inducer.
