Novel small molecule combinations that favour CRISPR/Cas-mediated homology-directed repair

CRISPR/Cas9 technology can be used for both gene knock-out and knock-in to reverse the effect of a mutated gene.

DNA double strand breaks (DSBs) are generated by CRISPR/Cas9, which are typically repaired by the competing repair pathways, non-homologous end joining (NHEJ) or homology-directed repair.

Precise genome editing is facilitated by HDR; however, its efficiency is low and the NHEJ pathway is the preferred choice for repair.

Strategies used to increase HDR rates include:

  • Synchronisation of cells (S-phase)
  • Overexpression of HDR mediators
  • Use of small molecules
