Choosing the right cell-based screen from the plethora of options available can quickly become a complicated decision process. Here, we review two of the major options: cell panel and functional genomic screening.
RNA sequencing (RNA-seq) of oncogenic fusions is becoming increasingly popular in cancer research and diagnosis. Here, we talk about the benefits of using RNA in fusion detection workflows, the challenge of workflow variability and how to be confident of your assay results.
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.
