Genes in the RAS pathway regulate the growth, differentiation, and survival of cells. The overactivation of the RAS pathway therefore can lead to cancer. Indeed, approximately 95% of pancreatic cancers are driven by mutations in genes within the RAS pathway. However, because the RAS pathway also functions in normal cells, it has been challenging to develop drugs that specifically impact RAS activity in tumors without also harming normal cells. Crabtree and Gray, with the support of the SCI Pancreatic Cancer Innovation Award, are taking a creative approach to address this challenge. They plan to use the specific overactivation of RAS in cancer cells to target these same cells. They will use specifically developed small molecules to re-wire the RAS pathway, such that, instead of promoting growth, it activates a cellular program causing cell death. Importantly, these molecules will only kill cells containing the overactive RAS pathway. Because mutations causing RAS pathway overactivity are unique to cancer cells, these small molecules should kill cancer cells without harming normal cells.
