Project description:Porcine respiratory and reproductive syndrome virus (PRRSV) is a virus infecting swine and causes swine abortion. Previously, non-structural protein 11 (Nsp11) from PRRSV was shown to have inhibitory function to type I IFN signaling. In this project, we want to see in addition to type I IFN, whether other cellular pathways are influenced by Nsp11 systemtically. A cell line stably expressing PRRSV Nsp11 was established, designated as MARC-Nsp11 cells, and an RNA microarray was conducted using these cells and WT MARC-145 cells MARC-145 and MARC-Nsp11 cells were seeded one day prior to experiments and total cellular RNAs were extracted using Trizol (Invitrogen) and purified by RNeasy mini kit (Qiagen). The quantity and quality of RNA were determined using an Align 2100 bioanalyzer (Agilent Technologies, Palo, Alto, CA, USA), and the RNA integrity was determined above 7. The RNA samples were then subjected to microarray using Human Gene 1.0 ST arrays (Affymetrix UK Ltd, High Wycombe, UK) at the Keck Biotechnology Center, University of Illinois, Urbana, IL). The microarray was repeated twice in duplicates each.

Project description:We found that fuse ΔLMP1 to MAVS could strengthen MAVS mediated inhibition of PRRSV replication in MARC-145 cells. To better understand the biological function of the fusion protein ΔLMP1-MAVS, overall gene expression of MARC-145 cells transfected with ΔLMP1-MAVS or MAVS was evaluated by mRNA-seq. The result showed that ΔLMP1-MAVS upregulated a number of genes associated with innate immune responses to viral infection, including plenty of interferon-stimulated genes. This study provides reference date to research the working mechanism of ΔLMP1-MAVS.
