Transcriptomic profiling of human corona virus (HCoV)-229E -infected human cells

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.

HCoV-229E infection of the human HuH7 cell line [Experiment A]

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.

p97/VCP as a therapy target for developing drugs against human coronavirus

Project description:Understanding how human coronavirus dysregulate host proteome during infection in human cells will identify general pathways that are common to coronavirus infection. NMS-873 is an allosteric p97/VCP ATPase inhibitor and was show to have antiviral effect in multiple viruses including SARS-CoV2. We first demonstrated that genetic knock down of p97 reduced HCoV-229E, HCoV-OC43 infection and secretion. To investigate how p97/VCP assists virus infection, we used unbiased quantitative proteomics to compare dysregulated proteomes caused by HCoV-229E, HCoV-OC43 and SARS-CoV2 infection. We then compared dysregulated proteomes after HCoV-229E and HCoV-OC43 infection with and without p97 knockdown. Moreover, we elucidated the impact of p97 on different stages of viral life cycle using two potent p97 inhibitors, CB-5083 and NMS-873 and demonstrate their can block HCoV replication. Together, our data provide insights to repurpose potential cancer drugs that target the essential host protein p97/VCP.

ChIP-seq analysis of coronavirus-infected human cells

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.

Time-course of HCoV-229E infection of A549 cells

Project description:The aim of the experiment is to identify kinetic changes in host gene expression upon infection of A549 lung epithelial carcinoma cells with human corona virus HCoV-229E as compared to unifected cells. Negativ controls include infections with heat-inactivated virus. Positive controls include treatment of cells with human IL-1alpha (10ng/ml) for 1h. All experiments have been performed at 33°C which is required for sufficient viral entry/replication.

Global transcriptomic analysis of hepatocyte cells infected with Ebola virus (EBOV)

Project description:We performed transcriptomic analysis of a Ebola virus (EBOV) infected hepatocyte cells. We utilized primary human hepatocytes (PHHs), iPSC-derived hepatocytes (iHeps), and immortalized hepatocarcinoma cell line Huh7 cells. Cells were infected with a multiplicity of infection of 10 and harvested after 1 day. Corresponding Mock infected samples were also included in this study.
