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.
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).
Project description:In the study presented here, A549 cells infected with influenza virus A /JingFang/86-1(H1N1) for 4 and 24 hours and intervention by Flutide, was used to acquire expression profiles of a total of 471 standard mature miRNAs based on Sanger miRBase Release 9.2.
Project description:Although accumulating evidence has shown that long non-coding RNAs (lncRNAs) are involved in multiple biological processes, considerably less is known regarding their functions in influenza A virus (IAV) replication. Here, lncRNA expression profiles were determined by RNA sequencing in three pairs of influenza virus A/Puerto Rico/8/34 (H1N1)-infected or uninfected A549 cells.
Project description:Transcriptome analysis of mock or H1N1 IAV PR8 infected p53WT A549 and p53null A549-KO3 cells by Affymetrix GeneChip Human Transcriptome 2.0 Arrays to achieve a set of genes those are regulated by p53 and responsive to IAV infection. Influenza A virus infection activates cellular p53, however it has not been clear whether this process has pro- or anti- viral effects. In this study, using human isogenic p53 wildtype A549 cells and p53null A549-KO3 cells generated from the CRISPR/Cas9 technology, we report that p53null cells exhibit significantly reduced viral propagation property when infected with influenza A virus (H1N1/A/Puerto Rico/8/34). Here, using genome-wide microarray analysis we revealed that p53 regulates the expression of a large set of interferon-inducible genes, some of which are directly associated with viral infectivity and later experimentally validated to be responsible for p53-regulated IAV infectivity.
Project description:A growing body of evidence suggests gene regulatory functions for the majority of non-protein-coding RNAs (ncRNAs). Besides small RNAs (sRNAs), the diverse class of long ncRNAs (lncRNAs) recently came into focus of research. So far, the relevance of lncRNAs in infection processes remains elusive. Here, we report the differential expression of several classes of lncRNAs during influenza A virus (IAV) infection in human lung epithelial cells. 2 biological replicates of each condition were hybridzed in an independent color-swap; A549 cells were washed with PBS and then infected with viruses at MOI 1 in infection buffer for for 60M-bM-^@M-^Imin at room temperature. Cells were incubated for the indicated time periods at 37M-bM-^@M-^IM-BM-0C in DMEM supplemented with 0.2% bovine serum albumin, 4M-bM-^@M-^ImM l-glutamine and antibiotics. Supernatants of A/WSN/33 (H1N1) virus infected A549 cells (MOI 5, 4hpi) were exposed to UV light for 5 min and then used to stimulate A549 cells for 4 h Supernatants of A/WSN/33 (H1N1) virus infected A549 cells (MOI 5, 8hpi) were exposed to UV light for 5 min and then used to stimulate A549 cells for 8 h
Project description:We used the microarray data to analyze host cells response on A549 cells infected with A/WSN/33 (H1N1) The A/WSN/33 (H1N1) infected A549 cells were harvested at 10 hpi and RNA extraction was performed using standard protocol as described by Affymetrix. The aim of this experiment is to analyze host response to Influenza A/WSN/33 (H1N1) infection.
Project description:We used the microarray data to analyze host cells response on A549 cells infected with A/WSN/33 (H1N1) The A/WSN/33 (H1N1) infected A549 cells were harvested at 2, 4 and 6 hpi and RNA extraction was performed using standard protocol as described by Affymetrix. The aim of this experiment is to analyze host response to Influenza A/WSN/33 (H1N1) infection.
Project description:To investigate whether influenza A virus (IAV) infection alters cellular miRNA profiles, A549 cells were either mock-infected or infected with two different subtypes of IAV, A/Beijing/501/2009 (H1N1; MOI=5) and A/Vietnam/1194/2004 (H5N1; MOI=2), for 24 or 48 h. Total RNA was purified from cell samples, and microarray analysis of miRNAs was performed. The expression of selected miRNAs was further confirmed by quantitative real-time PCR.
