Cas systems provide a means for modifying genomic information and have the
potential to revolutionize the treatment of genetic diseases. Although RNA-programmed
Cas9 has proven to be a versatile tool for genome engineering in multiple cell types
and organisms, it has been challenging to develop the therapeutics because they
require the simultaneous in vivo delivery of the Cas9 protein, guide RNA and
donor DNA. Compositions that can increase the efficiency of such delivery,
particular in eukaryotic cells, are greatly needed.
UC Researchers have discovered that the inclusion of an
agent that decreases the acidity of an endosome inside eukaryotic cells, in a
genome editing composition, increased the efficiency of genome editing. The agent was included in a composition having
an RNA-guided endonuclease and an RNA-guided endonuclease and was used for gene
editing.
