About DSA-Funded Research

Much of glioblastoma therapeutic efforts have been focused on direct inhibition of oncogenes or genes modulating the tumor microenvironment. However, there is genetic evidence suggesting a broader class of therapeutic targets. It has long been observed in yeast and other genetic models that certain combinations of mutations result in cell death, when each mutation alone fails to produce such an effect. This phenomenon is known as synthetic lethality. It is thought that the first mutation introduces cellular stress that forces the cell to depend on compensatory processes that are then inactivated by the second mutation. The principle of synthetic lethality should be applicable to oncogenes since they are fundamentally mutated genes. The implication is that the tumor state depends on the activities of a wide variety of compensatory pathways that are not directly related to the oncogene itself. One study in yeast identified an average of six synthetic lethal combinations per mutation, suggesting that there are at least six distinct ways to kill cancer cells beyond direct oncogenic inhibition. The funding provided by the Sontag Foundation affords an opportunity to explore this paradigm as means for glioblastoma therapeutic development.
