Genome-scale CRISPR-Cas9 screen of OVCAR3 and CCL218 cancer cells with or without hydroxychloroquine

ABSTRACT: A Brunello CRISPR-Cas9 library screen was performed with OVCAR3 and CCL218 cells in the presence or absence of hydroxychloroquine. Drug pulse chases were used, with 48h of drug exposure followed by replacement of fresh media. Cells were allowed to grow to near confluence and then another drug pulse-chase was performed. After each pulse-chase, a pool of cells were collected for sgRNA quantitation. Three pulse chases were performed. Cell pellets were processed for genomic DNA and sgRNA sequences amplified by PCR for NGS-based quantitation. Once quantified by NGS analysis, MAGeCK MLE analysis was performed to determine which sgRNAs were most associated with resistance or sensitization to hydroxychloroquine.

RNA-seq of OVCAR3 and CCL218 cancer cells with evolved hydroxychloroquine resistance

Project description:OVCAR3 and CCL218 cells were passaged in the presence or absence of hydroxychloroquine. Drug pulse chases were used, with 48h of drug exposure followed by replacement of fresh media. Cells were allowed to grow to near confluence and then another drug pulse-chase was performed. After 15 hydroxychloroquine pulse-chases, cells were allowed to proliferate for 7 days in drug-free media so that transient drug effects were no longer present. Cells were then pelleted and cell pellets were processed for concomitant bulk RNA-seq, whole-exome-sequencing, and single-cell RNA-seq. This project represents the bulk transcriptomic sequencing and analysis.

Thiouracil Pulse-chase, Tachyzoites and Bradyzoites mRNA stability data

Project description:Pulse chase measurements using thiouracil (DTU) labeling via UPRT and chasing with uracil Data from tachyzoites is labeled "DTU Pulse Chase". Two independent pulse chase experiments were performed in tachyzoites, pulse chase 1 and 2. Duplicate arrays at each timepoint were performed for pulse chase 2 (2 a and b). Data from bradyzoites are labeled "DTU Bradyzoite Pulse Chase". Two independent pulse chase experiments were performed in bradyzoites and a single set of arrays were performed for each experiment. Just one chase timepoint was used in the bradyzoite experiments, the 2 hour chase. An RNA stablity experiment design type examines stability and/or decay of RNA transcripts.

Hydroxychloroquine inhibits trained immunity

Project description:We demonstrate that hydroxychloroquine inhibits trained immunity at the functional and epigenetic level and is accompanied by reduced expression of interferon-stimulated genes. Trained immunity comprises a functional adaptation induced by epigenetic reprogramming which facilitates the anti-viral innate immune response.

Hydroxychloroquine inhibits responses to group A streptococcus in peripheral blood mononuclear cells

Project description:Immune responses to group A streptococcus in humans can lead to the development of acute rheumatic fever and rheumatic heart disease. Immune pathways that are activated by group A streptococcus are potential targets for inhibiting autoimmune responses to group A streptococcus. This experiment tests the impact of the drug hydroxychloroquine on immune responses to group A streptococcus in peripheral blood mononuclear cells

RNA-seq of THP-1 cells stimulated with CpG-c and Hydroxychloroquine intervention

Project description:Purpose: To investigate the inhibition of inflammatoty cytokines of Hydroxychloroquine to phagocytic THP-1 cells. Methods: we established a cell model of hemophagocytosis by simulating THP-1 cells with CpG-c for 24h in vitro to produce macrophages, and then coculture the cells with human RBCs. RNA sequencing analysis of THP-1 cells were performed to find Gene changed with CpG-c stimulation and Hydroxychloroquine intervention. Results:CpG-c sitimulation significantly altered gene expression of THP-1 cells. Cytokine genes were upregulated, especially a significant increase in IL-6 level from scratch. HCQ significantly inhibited the expression of inflammatory cytokines and decreased IL-6 gene level to baseline. Conclusions:Hydroxychloroquine can inhibite cytokine genes, especially IL-6 Gene level of THP-1 cells caused by CpG-c sitimulation.

Genomewide measurements of whole embryo mRNA decay in Drosophila

Project description:whole embryo (all tissues) measurement of mRNA decay by 4-thiouridine pulse-chase These TU-Decay microarrays analyze mRNA levels at three timepoints: a one hour pulse, one hour chase, and three hour chase. Measurements with or without transcription inhibition by actinomycin D (ActD) were compared.
