Project description:We performed a genome-scale screen for suppressors of interferon stimulated gene (ISG) expression in human haploid cells (HAP1). Ubiquitin specific peptidase 14 (USP14) was a significant hit. In order to validate USP14 as a regulator of ISG expression, we created knockouts of USP14 in HAP1 cells using CRISPR-Cas9 and performed RNA-seq on coding RNA from USP14 KO and WT cells. This data was used to determine if ISGs were upregulated in USP14 KO HAP1 cells.
Project description:We performed a genome-scale screen for suppressors of interferon stimulated gene (ISG) expression in human haploid cells (HAP1). DEAD-box helicase 6 (DDX6) was a significant hit. In order to validate DDX6 as a regulator of ISG expression, we created knockouts of DDX6 in HAP1 cells using CRISPR-Cas9 and performed RNA-seq on coding RNA from DDX6 KO and WT cells. This data was used to determine if ISGs were upregulated in DDX6 KO HAP1 cells.
Project description:Sequencing was performed to assess the ability of Nanopore direct cDNA and native RNA sequencing to characterise human transcriptomes. Total RNA was extracted from either HAP1 or HEK293 cells, and the polyA+ fraction isolated using oligodT dynabeads. Libraries were prepared using Oxford Nanopore Technologies (ONT) kits according to manufacturers instructions. Samples were then sequenced on ONT R9.4 flow cells to generate fast5 raw reads in the ONT MinKNOW software. Fast5 reads were then base-called using the ONT Albacore software to generate Fastq reads.
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 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:Chromosome-centric Human Proteomic Project (C-HPP) aims at identifying and characterizing protein products encoded from all protein-coding genes of human chromosomes. As evident in the recent nature papers, it is possible that those missing proteins may be low abundant in many cell types or expressed only in a few cell types. In order to identify missing proteins, we focused on extensively unexplored cell lines(HAP1, KBM-7).
Project description:Activating Transcription Factor 4 (ATF4) is a transcription factor induced by the integrated stress response (ISR). This experiment is a genome-wide occupancy profiling of ATF4 in human HAP1 cells. HAP1 is a near-haploid human cell line that was derived from KBM-7 cells isolated from a patient with Chronic Myelogenous Leukemia. We induced ATF4 expression by mimicking amino acid starvation with the drug histidinol. We identified peaks of ATF4 binding using three independent antibodies. Examination of ATF4 binding in HAP1 cells treated with 2 mM histidinol for 24 hours.
