i.e. is there a type of drug that when given to cell population, would make them more likely to mutate with the addition of a DSB or SSB (zinc finger, crisper, nicks etc)? thanks
There is a couple of brand new papers that could address your question:
"Increasing the efficiency of precise genome editing with CRISPR-Cas9 by inhibition of nonhomologous end joining" Maruyama T et Al. doi:10.1038/nbt.3190
"Small Molecules Enhance CRISPR Genome Editing in Pluripotent Stem Cells" Yu C et Al. http://dx.doi.org/10.1016/j.stem.2015.01.003
