Giving Cas9 an ‘on’ switch for better control of CRISPR gene editing

Giving Cas9 an ‘on’ switch for better control of CRISPR gene editing | Genetic Engineering Publications - GEG Tech top picks | Scoop.it
CRISPR-Cas9 Circular Permutants as Programmable Scaffolds for Genome Modification
BigField GEG Tech's insight:

UC Berkeley researchers have made CRISPR/cas9 system even more versatile by giving it an “on” switch, allowing users to keep the Cas9 gene editor turned off in all cells except its designated target.

Targeted DNA degradation using a CRISPR device stably carried in the host genome - Nature Communications

Targeted DNA degradation using a CRISPR device stably carried in the host genome - Nature Communications | Genetic Engineering Publications - GEG Tech top picks | Scoop.it
BigField GEG Tech's insight:

In this study, the authors present a genetically encoded device (DNAi) based on CRISPR system. DNAi allows to degrade specific intracellular DNA with an inducible and targeted manner. When a plasmid is targeted, it is rapidly lost from a population, and when the genome is targeted, this results in rapid cell death. The DNAi device is non-toxic when carried in the genome, is stable for months and does not impart background activity until induced.

“Unexpected mutations after CRISPR-Cas9 editing in vivo” are most likely pre-existing sequence variants and not nuclease-induced mutations?

“Unexpected mutations after CRISPR-Cas9 editing in vivo” are most likely pre-existing sequence variants and not nuclease-induced mutations? | Genetic Engineering Publications - GEG Tech top picks | Scoop.it
BigField GEG Tech's insight:

“Unexpected mutations” simply represent SNPs and indels shared in common by these mice prior to nuclease treatment.
