CRISPR-CLEAR: Nucleotide-Resolution Mapping of Regulatory Elements via Allelic Readout of Tiled Base Editing

ABSTRACT: CRISPR tiling screens have advanced the identification and characterization of regulatory sequences but are limited by low resolution arising from the indirect readout of editing via guide RNA sequencing. This study introduces CRISPR-CLEAR, an end-to-end experimental assay and computational pipeline, which leverages targeted sequencing of CRISPR-introduced alleles at the endogenous target locus following dense base-editing mutagenesis. This approach enables the dissection of regulatory elements at nucleotide resolution, facilitating a direct assessment of genotype-phenotype effects.

Cut&Run-seq of MUTZ3 cells to investigate changes in a translocated enhancer following CRISPR treatment

Project description:We examined the effects of targeting the GATA2 super-enhancer on EVI1 expression in MUTZ3. To that end, we conducted genome editing with CRISPR and assessed H3K27 acetylation with Cut&Run. The protocol described by the Henikoff group was used to generate these data.

Next-generation Serology by Mass Spectrometry: Readout of the SARS-CoV-2 Antibody Repertoire

Project description:Methods of antibody detection are used to assess exposure or immunity to a pathogen. Here, we present Ig-MS, a novel serological readout that captures the immunoglobulin (Ig) repertoire at molecular resolution, including complete variable regions in Ig light and heavy chains. Ig-MS uses new advances in protein mass spectrometry (MS) for multi-parametric readout of antibodies, with new metrics like Ion Titer (IT) and degree of clonality (DoC) capturing the heterogeneity and relative abundance of individual clones without DNA/RNA sequencing of B cells. We apply Ig-MS to plasma from subjects with severe & mild COVID-19, using the receptor binding domain (RBD) of the spike protein of SARS-CoV-2 as the bait for antibody capture. Importantly, we report a new data type for human serology, with compatibility to any recombinant antigen to gauge our immune responses to vaccination, pathogens, or autoimmune disorders.

Genome-wide specificity of genome editing by both CRISPR-Cas9 and TALEN in the model plant Physcomitrium patens

Project description:CRISPRs and TALENs are efficient systems for gene editing in many organisms including plants. In many cases the CRISPR-Cas or TALEN modules are expressed in the plant cell only transiently. Theoretically, transient expression of the editing modules should limit unexpected effects compared to stable transformation. However, very few studies have measured the off-target and unpredicted effects of editing strategies on the plant genome, and none of them have compared these two major editing systems. We conducted a comprehensive genome-wide investigation of off-target mutations using either a CRISPR-Cas9 or a TALEN strategy. We observed a similar number of SNVs and InDels for the two editing strategies compared to control non-transfected plants, with an average of 8.25 SNVs and 19.5 InDels for the CRISPR-edited plants, and an average of 17.5 SNVs and 32 InDels for the TALEN-edited plants. Interestingly, a comparable number of SNVs and InDels could be detected in the PEG-treated control plants. This shows that except for the on-target modifications, the gene editing tools used in this study did not show a significant off-target activity nor unpredicted effects on the genome, and that the PEG treatment in itself was probably the main source of mutations found in the edited plants.

rRNA 2'-O-methylation profile of SNORD71 knockdown cells

Project description:We generated a SNORD71 KO chondrocyte cell pool using CRISPR/Cas9 gene editing. A CRISPR control cell line was generated and used as a control. Levels of 2’-O-methylation of human rRNAs in SNORD71 KO cell pool and CRISPR control cells were evaluated by RiboMethSeq.

Amplicon sequencing of a K562 cell line model with a patient-based t(3;8) translocation following CRISPR treatment

Project description:Genome editing was conducted on a t(3;8) K562 model to investigate the effects of deleting different modules or CTCF binding sites within the MYC super-enhancer. To check mutations after targeting with CRISPR-Cas9 we performed amplicon sequencing using the Illumina PCR-based custom amplicon sequencing method using the TruSeq Custom Amplicon index kit (Illumina). The first PCR was performed using Q5 polymerase (NEB), the second nested PCR with KAPA HiFi HotStart Ready mix (Roche). Samples were sequenced paired-end (2x 250bp) on a MiSeq (Illumina).

Single cell RNAseq of haploidized HCT116 colorectal carcinoma cells expressing specific p53 mutations treated with either DMSO or Nutlin

Project description:Colorectal carcinoma cell line HCT116 cells were used as a model system to investigate the heterogeneity of different TP53 mutations. To this end, cells were haploidized by deleting an intronic splice site in one of the two wild-type TP53 alleles while the other copy was altered to different loss-of-function mutants via CRISPR/Cas9 gene editing. Cells expressing different haploid TP53 genotypes were treated with either Nutlin or DMSO to investigate the genetic variation between the mutants and the wild-type genotype.
