Funded Activity Summary

Modern chemotherapies are designed to exert maximal effect on tumour cells while having minimal side-effects on normal cells. Remarkable advances in our understanding of the molecular biology of cancer has provided possible avenues for more successful targeted cancer treatments. Several crucial interactions between cancer-specific proteins called oncoproteins , occur largely in tumour cells and thus provide ideal targets for intervention. The proposed project is to develop a model system for a target specific therapy of leukaemia cells by blocking the interactions between oncoproteins. Moreover, the ability to isolate specific blockers of particular protein-protein interactions provides an opportunity to unravel complex genetic pathways in mammalian systems, which are relatively intractable by other analyses. The dissection of pathways using specific blockers may also provide a useful avenue for identifying new drug targets. We have chosen to target particular interactions involving one known oncoprotein in the search for specific inhibitors. A genetic selection will be used to identify random, constrained peptide sequences which are capable of blocking these interactions and which do not interfere with other interactions involving the oncoprotein. This technique allows one to select for or against specific blockers of known interactions from a library containing millions of candidate drug leads in baker's yeast cells. This procedure will be most suitable for high through-put drug screening projects. The validity of this approach to the identification of new peptide drug leads will be finally established in vivo using transgenic models of oncoprotein-dependent cancer in mice.
