Project description:To explore the effects of SARS-CoV-2 proteins on expression of host genes in lung of infected mice, 4 groups of K18-hACE2 mice (4 mice per group) were mock-infected or infected cells with SARS-CoV-2 WT or its NPS1, or NSP15 mutants respectively.The mice were euthanized at 4 days post-infection to collect the lungs to isolate RNA for RNA sequencing.
Project description:Purpose : The goal of this study was to use RNA Seq to define the regulon of the transciption factor Anr by comparing global transcriptional profiles of Pseudomonas aeruginosa strain PAO1 and a clinical isolate with their isogenic ∆anr mutants, grown in colony biofilms at 1% oxygen. Methods : mRNA profiles were generated for laboratory strain PAO1 and for a clinical isolate J215, as well as for ∆anr derivatives of each strain, in duplicate, by deep sequencing. Strains were grown for 12 hours in colony biofilms at 1% O2, 5% CO2 prior to RNA harvest. Ribosomal and transfer RNAs were removed using the MICROBExpress kit (Life Technologies). mRNA reads were trimmed and mapped to the PAO1 NC_002516 reference genome from NCBI using the ClC Genomics Workbench platform and defaut parameters.
