Colorectal Cancer Scientists

Dr Kirk McManus, PhD

Genome instability is associated with virtually all cancer types, but the underlying gene defects and mutations causing genome instability are not well understood. Mutations that cause chromosome instability (CIN), or abnormal chromosome numbers, are now widely recognized as predisposing factors that drive cancer formation. In fact, mutations in CIN genes are associated with disease progression, the acquisition of drug resistance and poor patient survival. Nevertheless, and despite these associations, the mutated genes giving rise to CIN remain largely unknown. Thus, a fundamental goal of our research team is to identify and characterize new CIN genes, and to uncover their roles in cancer development. To achieve this goal, we routinely couple genetics, biochemistry, cell biology, molecular biology and high-content imaging microscopy to identify the mutated genes and abnormal pathways that drive colorectal and ovarian cancer formation.

The second major goal of our research team is to identify and develop novel therapeutic strategies to combat cancers, like colorectal, ovarian and breast. In this regard, we use genetics, cell biology and innovative microscopy approaches to screen and identify new drug targets and lead chemotherapeutics that specifically kill cancer cells with mutated CIN genes. A major benefit of this approach is that the therapeutic effects are better targeted towards cancer cells, and thus it is predicted to minimize and/or eliminate the adverse side effects associated with many current chemotherapeutics. This innovative cancer-specific targeting concept is referred to as synthetic lethality and is now beginning to show promise within the clinic.
