Project description:This dataset contains ChIP-seq data profiling genomic binding of H3K27ac and H3K4me3 in single cell-derived control, as well as CRISPR/Cas9 induced tRNA gene deletion clones and intergenic region deletion clones in human cancer cell lines HAP1. In this study, we found a large genomic deletion of 10q23 in Cas9 modified clones and further investigate the effect of H3K27ac binding.
Project description:This dataset contains ChIP-seq data of H3K4me3 and Pol III in single cell-derived control and CRISPR/Cas9 induced tRNA gene deletion clones in human cancer cell lines HAP1 and HepG2. In this study, we looked into functional Cas9-induced on-target genomic alteration in our tRNA gene deletion clones, HAP1 t72 and HepG2 t15.
Project description:This dataset contains ploy-A tailed enriched RNA-seq data obtained from single cell-derived control and CRISPR/Cas9 induced tRNA gene deletion clones in the human cancer cell line HAP1. In this study, we found a large genomic deletion of the 10q23 locus in our Cas9 modified clones and further investigate the effect on the transcriptome.
Project description:Identifying putative transcription factor target genes by combining CRISPR/Cas9-based transcriptional activation with RNAseq in Drosophila S2R+ cells. This study focuses on the transcription factors Twist and Snail, singly and together. RNA from Drosophila cells following CRISPR/Cas9-based activation of Twist, Snail, or Twist and Snail together, compared with non-targeting sgRNA. Two biological replicates for each experiment
Project description:In this study we investigate the effects of CRISPR/Cas9 mediated deletion of STIM genes on gene expression in both SH-SY5Y and in HEK293 cell lines.
Project description:Cdc42 is a Rho family GTPase known for its central role in cell polarity and cytoskeletal regulation. To understand the role of Cdc42 in polarised secretion from cytotoxic T lymphocytes (CTLs) we used CRISPR/Cas9 gene deletion. While Cdc42-deleted CTLs initially showed reduced secretion for up to two days after CRISPR-mediated deletion, full secretion was rapidly restored and even enhanced while CDC42 protein remained absent. In contrast, chemical inhibition of CDC42 using CASIN consistently decreased secretion in wild-type cells, but had no impact on Cdc42-deleted CTLs, confirming the specificity of this inhibitor. Comparative proteomics and transcriptomics of CTLs after Cdc42-deletion revealed transcriptional changes that could support improved T cell function including compensation via other Rho GTPases. Targeting the promoter region of Cdc42 did not trigger transcriptional adaptation, consistent with a nonsense-mediated decay mechanism of genetic compensation. Our work highlights the importance of taking orthogonal approaches to study protein function, and reveals the remarkable robustness of primary T cells to adapt to loss of an essential gene.
Project description:CRISPR/Cas9 system was used to generate mediator complex subunit 1 (MED1) knockout human pre-B ALL cell line 697. RNA-seq was performed to observe the effects of MED1 deletion on gene expression in 697.
