A number of siRNA and shRNA screens have identified targets that exhibit differential dependencies between KRAS mutant and KRAS wild-type tumours, but there is poor overlap between these published studies. Next generation screens that exploit both isogenic cell lines and cancer cell panels, and use a combination of knockdown (si/shRNA) and knock-out (CRISPR-Cas9-sgRNA) methodologies might be more effective at identifying novel targets that withstand validation. However, if we are to detect co-dependence as well as synthetic lethal interactions, screens must be performed under conditions where mutant KRAS alleles are essential for growth.
