Massively parallel quantification of SpCas9 gRNA efficiencies by surrogate lentiviral libraries

Project description:In this study, we used a surrogate lentivirus library to capture CRISPR editing outcome in HEK cells. The dataset include quantification of indel frequencies for SpCas9 gRNAs in 12,000 surrogate sites. After filtering low quality sites, the high quality SpCas9 gRNA activities from a total of 10592 sites have been used to develop an improved deep learning-based prediction model CRISPRon (https://rth.dk/resources/crispr/.).

Detecting non-canonically-targeted SpCas9 generated DSBs in human cells by LAM-HTGTS

Project description:We identified robust cleavage by non-canonically-targeted SpCas9 that target protospacer with a few bases from the canonical NGG PAM in biochemistry assay. To determine whether this spaced SpCas9 cleavage exists in human cells, we employed high-throughput genome-wide translocation sequencing (LAM-HTGTS) using SpCas9 with three independent canonical sgRNAs served as bait (bait-A, bait-L and bait-D) to compared the cleavage activities of canonically-targeted and non-canonically-targeted SpCas9 in eight locus (RAG1B-D, RAG1K-O) in chromosome 11. We found that almost all 1bp-target shifted SpCas9 generated substantial DSBs as the canonical controls. While detected less frequently, 2bp-targeted shifted SpCas9 generated significant amounts of DSBs in RAG1D and RAG1L locus. These findings underscore the spaced PAM-mediated DSBs occurred in living cells.

Benchmarking of SpCas9 variants enables deeper base editor screens of BRCA1 and BCL2

Project description:Numerous rationally-designed and directed-evolution variants of SpCas9 have been reported to expand the utility of CRISPR technology. Here, we benchmark PAM preferences, on-target activity, and off-target susceptibility of 11 variants of SpCas9 in cell culture assays with thousands of guides targeting endogenous genes. To enhance the coverage and thus utility of base editing screens, we demonstrate that the SpCas9-NG and SpG variants are compatible with both A>G and C>T base editors, more than tripling the number of guides and assayable residues. We demonstrate the performance of these technologies by screening for loss-of-function mutations in BRCA1 and Venetoclax-resistant mutations of BCL2, identifying both known and new insights into these clinically-relevant genes. We anticipate that the tools and methodologies described here will facilitate the investigation of genetic variants at a finer and deeper resolution for any locus of interest.
