Project description:The aim of the experiment is to identify changes in host gene expression upon infection of HuH7 human hepatoma cells with Human corona virus-229E (HCoV-229E) compared to mock-infected cells. All experiments were performed at 33°C which is required for sufficient viral entry/replication.
Project description:The aim of the experiment is to identify chromatin and transcription factor binding dynamics in host gene expression upon infection of human Huh7 hepatoma carcinoma cells with human coronavirus HCoV-229E as compared to uninfected cells and in comparison to cells stimulated by IL-1alpha (10ng/ml) for 1h. All experiments have been performed at 33°C which is required for sufficient viral entry/replication.
Project description:The purpose of this experiment was to evaluate how wild-type Human coronavirus strain 229E (HCoV-229E) infection alters chromatin accessiblity in infected but not mock-infected samples.

Also included are two samples which have been treated with a heat inactivated coronavirus (56°C for 5min).
Project description:The aim of the experiment is to identify and compare changes in host gene expression of Huh-7 cells (human liver carcinoma cells) infected with Human coronavirus 229E (HCoV-229E, WT) or genetically engineered HCoV-229E mutants in which the phosphorylation status of the structural N protein has been altered by two combined Ser-to-Ala substitutions in each of the two mutants (S147A+S149A and S364A+S367A, respectively). For each of the two N protein mutants, two individual molecular clones were isolated and used in this experiment. The two N protein mutants grow to (slightly or moderately) lower titers in cell but it is not known if (and to what extent) the respective phosphorylations of the nucleocapsid protein affect the cellular transcriptome following infection by HCoV-229E. All experiments were performed at 33°C which is required for efficient replication of this virus.
Project description:Human coronaviruses (HCoVs) cause mild to severe respiratory infection. Most of the common cold illnesses are caused by one of four HCoVs, namely HCoV-229E, HCoV-NL63, HCoV-HKU1 and HCoV-OC43. Several studies have applied global transcriptomic methods to understand host responses to HCoV infection, with most studies focusing on the pandemic severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome CoV (MERS-CoV) and the newly emerging SARS-CoV-2. In this study, Next Generation Sequencing was used to gain new insights into cellular transcriptomic changes elicited by alphacoronavirus HCoV-229E. HCoV-229E-infected MRC5 cells showed marked downregulation of superpathway of cholesterol biosynthesis and eIF2 signaling pathways. Moreover, upregulation of cyclins, cell cycle control of chromosomal replication, and role of BRCA1 in DNA damage response, alongside downregulation of the cell cycle G1/S checkpoint, suggest that HCoV-229E favors S phase for viral infection. Intriguingly, more than 80% of key factors of cell innate immunity, interferon-stimulated genes (ISGs) and other transcripts of early antiviral response genes were downregulated early in HCoV-229E infection. This study will enhance our understanding of commonly circulating HCoVs and hopefully provide critical information about still-emerging coronaviruses.
Project description:The purpose of this experiment was to evaluate the human host cellular response to wild-type Human coronavirus strain 229E (HCoV-229E) infection. Sample data was obtained for mock and infected (MOI 3) primary human airway epithelial cells grown in air-liquid interface conditions, processed for RNA sequencing (RNA-Seq) expression analysis.

Sample data was obtained for mock and infected (MOI 5) immortalized human lung epithelial cells (A549) and immortalized human lung fibroblasts cells (MRC5) processed for RNA sequencing (RNA-Seq) expression analysis.
Project description:The purpose of this experiment was to evaluate the human host cellular response to wild-type Human coronavirus strain 229E (HCoV-229E) infection in the presence and absence of macrophages. Sample data was obtained for mock and infected (MOI 3) primary human airway epithelial cells with and without macrophages and grown in air-liquid interface conditions, processed for RNA sequencing (RNA-Seq) expression analysis.
