Development of Novel Peptide Inhibitors to BAG-1. Applications of Peptidyl-Biomimetics to reduce and eliminate tumor resistance to chemotherapy

      Аннотация: One of the most challenging aspects of treating tumors with chemotherapy is that the tumors can develop a resistance to the chemotherapy and survive while the rest of the healthy, non-cancerous cells perish. Higher doses of chemotherapy deliver fewer positive results and at the expense of greater side effects. The purpose of this book it to identify and exploit a weakness at the molecular level of the anti-apoptotic pathway utilized by cancer cells to turn off the "triggered cell death" mechanism of apoptosis and survive chemotherapy. We specifically target the interaction between the anti-apoptotic protein Bcl-2 Associated Athanogene (BAG-1) and the 70-kilodalton Heat Shock Protein (HSP-70) that is suspected of driving the chemotherapeutic resistance, and seek to disrupt that interaction via peptidyl-biomimetically engineered peptides that are predicted via an in-house computational software named 'Contact" and experimentally verified via Biacore (c) binding assays.
