- W1963539723 abstract "Proceedings: AACR 104th Annual Meeting 2013; Apr 6-10, 2013; Washington, DCActivating KRAS mutations are oncogenic and prevalent in multiple tumor types, being found in as high as 90% of pancreatic carcinomas and 50% of colorectal carcinomas. In spite of its attractiveness for therapeutic intervention to date no KRAS-targeted drug therapies have been approved. Most of the reported mutant KRAS directed cellular screening efforts utilize 2-dimensional assays. Because mutant KRAS driven tumor cell lines are much more strongly dependent on activated K-Ras signaling for anchorage independent growth relative to growth when anchored to plastic, we report herein a screening strategy that leverages a 3-dimensional clonogenic growth assay in soft agar. We have performed a multi-cell line parallel phenotypic high throughput screen with our proprietary compound collection to identify pathways, targets and chemical matter with selective anti-tumor activity in mutant KRAS dependent cell lines - a Synthetic Lethal approach.Our strategy has led to the identification of several chemical classes that inhibit the growth of multiple mutant KRAS cell lines of pancreatic and colorectal carcinoma origin, while sparing multiple wild-type KRAS cancer cell lines. Studies to elucidate their molecular mechanisms of action are underway.Citation Format: Malvika Koundinya, Judith Sudhalter, Albane Courjaud, Bruno Lionne, Gaetan Touyer, Luc Bonnet, Isabelle Menguy, Isabelle Schreiber, Christelle Perrault, Stephanie Vougier, Brigitte Benhamou, Daniel Simard, Maria Paola Castaldi, Ronald Tomlinson, Stephan Reiling, Hui Cao, David Harper, Monsif Bouaboula, Jack Pollard, Claudine Grepin, Carlos Garcia-Echeverria, Francisco Adrian, Ivan Cornella-Taracido, Rosalia Arrebola, Aaron J.
