Gene expression changes due to influenza virus induced miRNAs

Project description:The goal of this experiment was to determine gene expression changes during influenza A virus infection as the result of expression influenza virus inducible miRNAs in A549 cells. The gene expression profiling experiment was performed with 4 groups (mock infected, influenza A virus infected, influenza A virus infected in the presence of exogenous miR-141, miR-374b, miR-449b, miR-518b, and miR-1263, and influenza A virus infected in the presence of exogenous miR-147b, miR-190b, miR-199a, miR-512-5p, and miR-874 with 3 biological replicates for each group. Total RNA was purified from A549 cells that were mock infected or infected with influenza A virus (A/WSN/33, 5pfu/cell) alone or in the presence of miRNA mimics 10 hours after treatment.

Influenza A virus induced proteome changes

Project description:Seasonal epidemics of influenza A virus in the human population are a major cause of severe illness and are of high socio-economic relevance. For the design of effective anti-viral therapies, a detailed knowledge of cellular pathways perturbed by virus infection is critical. We performed comprehensive expression and organellar proteomics experiments using A549, Calu-1 and NCI-H1299 cells to identify new protein targets and cellular pathways affected by influenza A virus.

Effect of Influenza virus infection on lncRNA expression in A549 cells

Project description:Long non-coding RNAs (lncRNAs) are a new arm of gene regulatory mechanism as discovered by sequencing techniques and follow-up functional studies. There are only few studies on lncRNAs as related to gene expression regulation and anti-viral activity during influenza virus infection. We sought to identify and characterize lncRNAs involved in influenza virus replication. In the current study, we identified dys-regulated lncRNAs in influenza virus-infected human lung epithelial A549 cells using RNA sequencing in A549 cells.

Analysis of global gene expression profiles of hPAF1 deficient A549 cells during infection with H1N1 influenza A virus or vesicular stomatitis virus (VSV)

Project description:Viral infection is commonly associated with virus-driven hijacking of host proteins. We describe a novel mechanism by which influenza virus impacts host cells through the interaction of influenza NS1 protein with the infected cell epigenome. We show that the NS1 protein of influenza A H3N2 targets the transcription elongation PAF1 complex (hPAF1C). We demonstrate that binding of NS1 to hPAF1C results in suppression of hPAF1C-mediated transcriptional elongation. More importantly,in the following data sets, we show that hPAF1 plays a crucial role in the antiviral response. Loss of hPAF1C reduces antiviral gene expression and reduces inducible transcription of target genes after stimulation with viral RNA analogue poly(I:C), vesicular stomatitis virus (VSV), exogenous recombinant IFN(beta) and influenza virus (H1N1). This study underscores the importance of hPAF1C in controlling inducible antiviral gene expression. Untreated (no siRNA), control siRNA-treated and hPAF1 siRNA-treated A549 cells were stimulated with A/Puerto Rico/8/1934 influenza virus (H1N1) or vesicular stomatitis virus (VSV). Total RNA was isolated with the Qiagen RNeasy mini kit. 200ng of total RNA per sample was used to prepare biotin-labeled RNA using MessageAmp™ Premier RNA Amplification Kit (Applied Biosystems) and hybridized to HumanHT-12 v4 Expression BeadChips (Illumina). Data analysis was performed using the GeneSpring GX11.0 software (Agilent Technologies). 3 biological replicates per condition

C646, a Novel p300/CREB-Binding Protein-Specific Inhibitor of Histone Acetyltransferase, Attenuates Influenza A Virus Infection

Project description:Whole-genome data was developed from influenza virus infected A549 cells to better characterize the effect of C646 on influenza virus infection A549 cells were treated with C646 or DMSO for 10 h, and then were infected with A/WSN/33 virus (WSN; H1N1) at a multiplicity of infection (MOI) 2. A549 cells for microarray studies were collected at different times. The gene expression in A549 cells was compared between C646-treated group and DMSO-treated group.

Differential miRNA expression profiling of A549 cells infected with influenza A virus

Project description:To further understand the roles of miRNA during influenza A virus infection, we performed miRNA profiling in human alveolar adenocarcinoma cell lines, A549 cells, infected with influenza A virus A/Beijing/501/2009(H1N1) and A/goose/Jilin/hb/2003(H5N1).
