Research Interests

Dr. Singh’s lab studies global mechanisms underlying oncogene-driven cancer progression. We use state of the art technologies, including gene expression profiling and RNAi-based screening. Subsequently, through application of functional genomics and systems pharmacology we identify novel oncogenic signaling networks that can be exploited for therapeutic target identification and validation. Current research in the lab seeks to identify KRAS-regulated signaling networks and to use this information to provide detailed mechanistic insight into KRAS-driven tumor progression. We are also interested in contextual variability in these networks based on tissue lineage and genetic background. Through this approach, we have identified a number of attractive candidate therapeutic targets that can be antagonized to promote cancer cell death in a context-dependent manner, such as the kinase TAK1 in colon cancers. Since effective pharmacological targeting of the mutant KRAS protein has proven challenging, a key translational goal is to identify clinically efficacious small molecule inhibitors against critical nodes in oncogenic KRAS signaling networks to provide benefit for patients with highly aggressive KRAS-driven cancers.
