Generation of scalable cancer models by combining AAV-intron-trap, CRISPR/Cas9, and inducible Cre-recombinase

Boddu et al combined AAV-intron trap, CRISPR/Cas9 and inducible Cre-recombinase systems to introduce the oncogenic K700E mutation in SF3B1, which is a splicing factor commonly mutated in multiple cancers, with more than 90% efficiency. Their approach can be readily adapted to generate scalable isogenic systems where mutant oncogenes are detrimental to cell culture growth.
