Insight into the Complexity of the i-Motif and G-Quadruplex DNA Structures Formed in the KRAS Promoter and Subsequent Drug-Induced Gene Repression.

Abstract excerpt

Activating KRAS mutations frequently occur in pancreatic, colorectal, and lung adenocarcinomas. While many attempts have been made to target oncogenic KRAS, no clinically useful therapies currently exist. Most efforts to target KRAS have focused on inhibiting the mutant protein; a less explored approach involves targeting KRAS at the transcriptional level. The promoter element of the KRAS gene contains a GC-rich...
