Project description:We performed a large-scale genome-wide characterisation of indels generated following editing with CRISPR/Cas9. We used pools of sgRNAs and performed targeted capture and sequencing of the edited regions in HepG2 cells.
Project description:We recreated the t(7;12) translocation in K562 cells by CRISPR/Cas9 to understand its effects on haematopoietic cells, which is of relevance to understand how this cytogenetic abnormalities causes and promotes acute leukaemia in infants. Wild-type K562 were edited by electroporation of ribonucleoprotein complexes consisting of Cas9 enzyme and two guide RNAs targeting patient-specific breakpoint loci. K562 electroporated with Cas9 enzyme only were used as control. Edited K562 harbouring the t(7;12) were single-cell cloned to obtain homogeneous populations (hereby referred to as K562-t(7;12)). We performed RNA sequencing analysis of K562-t(7;12) compared to K562 control to uncover transcriptional changes associated with the translocation.
Project description:In this study, human isogenic model of juvenile onset PD caused by DNAJC6 mutation were made. Human ESCs edited using CRISPR-Cas9 to make deleterious DNAJC6 mutation was induced to human midbrain like organoid (hMLO) for studying the mechanism of DNAJC6 deleterious mutation in causing PD
Project description:Provided data came from a detailed study on Nicotiana benthamiana 16c plants where we use Tobacco Rattle Virus (TRV) as a molecular switch to change the chromatin state of a reporter gene (P35S::GFP) from an actively transcribed to a transcriptionally silenced state. Our approach enables us to interrogate different chromatin states of the same locus with the same set of CRISPR/Cas9 genome editing reagents and systematically describe the effect of chromatin state on the frequency and type of mutations induced at various Cas9 targets in a huge set of independently edited cells.
Project description:Whole genome sequencing (WGS) data of human small intestinal organoid cultures, which were deleted for the XPC gene using CRISPR-Cas9. Contains WGS data of 1 clone and 1 subclone.
Project description:RNA-seq of human cells Edited using CRISPR vs parental and Unedited control. We identified a rare homozygous intronic variant in the ATP2B1 locus (rs111337717; chr12:89643729, T>C) that is associated with the severity of COVID-19 (i.e., symptomatic versus asymptomatic patients). Next, we employed CRISPR/Cas9 technology to develop the disease mutation observed in high-risk patients. Several edited single colonies were picked and expanded followed by DNA sequencing, and four clones with desired homozygous modifications were identified. The transcriptional profiles of N=4 C/C clones were compared then to those of T/T controls comprising one parental cell line and three unedited post-selection HEK293T cell clones.
Project description:The aim of this study was to determine the effects of TGFβ at the premalignant stage of CRC development. Organoid cultures were isolated from normal colon and from tubular adenomas. One normal colon culture was genetically engineered using the CRISPR-Cas9 system to carry the BRAFV600E mutation. Organoid cultures of three different tubular adenomas and two normal colon samples, and one BRAFV600E-mutant organoid culture received TGFβ or control treatment after which gene expression was analyzed by microarray (Affymetrix U133+ PM Genechip Array).
Project description:MCF10A cells were CRISPR-Cas9 edited to create heterozygous deletion in RAD21 and SMC3 subunits of cohesin. STAG2 is on the X chromosome, hence CRISPR-Cas9 editing resulted in complete loss of STAG2. Total RNA was sequenced from the MCF10A parental and cohesin mutant MCF10A lines. The acute megakaryoblastic leukaemia cell line CMK was CRISPR-Cas9 edited to cotain STAG2 R614* mutation. CRISPR-Cas9 edited STAG2 mutant line showed complete loss of STAG2. CMK parental and the STAG2 mutant line were treated with Wnt3a for 4 hours and total RNA was sequenced at in the control or non-treated (con) and following 4 hours of Wnt3a treatment (Wnt3a4hr).
Project description:We report a preliminary RNA-Seq data of MCF-7 cells edited in the FASN locus using CRISPR/Cas9. MCF-7 cells were edited by CRISPR/Cas9, screened by Surveyor assay, purified by limiting dilutions, validated by sanger sequencing, and characterized by diverse cellular analyses. Then, RNA from edited cells and non-edited controls were processed by TruSeq-RNA-Library-Prep-Kit and sequenced in a illumina equipment. Reads were aligned to hg38 in Galaxy using RNA-Star and transcripts were counted by FeatureCounts.
