NcRNA profiling after Influenza A/WSN/33 infection II

ABSTRACT: 8h and 24h after A/WSN/33 infection (MOI 1) ncRNA profiling was performed 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.

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

The miRNA expression patterns in WSN-infected A549 cells at various time points post-infection.

Project description:To identify miRNAs that are affected by IAV infection, we adopted a systematic approach, and performed a miRNA microarray analysis using a human alveolar adenocarcinoma cell line, A549, which was infected with a common laboratory strain of influenza A/WSN/33(H1N1) virus (WSN). We compared miRNA expression profiles in A549 cells infected with WSN for 2, 6, and 10 hours at a multiplicity of infection (MOI) of 2. Among 955 miRNAs on the microarray, 209 miRNAs were detected in all three infected A549 samples, but when compared with analysis results from mock-infected A549 cells, most expression changes were less than 1.5-fold , which was consistent with a previous report (Buggele et al., 2013). Therefore, we established 1.5-fold expression change as a threshold to select for miRNAs potentially affected by WSN infection. Further screening revealed 116 miRNAs that underwent 1.5-fold or greater expression changes at any timepoint following WSN infection.

The interaction of influenza A NS1 and cellular TRBP protein modulates the function of RNA interference machinery

Project description:Influenza A virus (IAV), one of the most prevalent respiratory diseases, causes pandemics around the world. The multifunctional non-structural protein 1 (NS1) of IAV is a viral antagonist that suppresses host antiviral response. However, the mechanism by which NS1 modulates the RNA interference (RNAi) pathway remains unclear. Here, we identified interactions between NS1 proteins of Influenza A/PR8/34 (H1N1; IAV-PR8) and Influenza A/WSN/1/33 (H1N1; IAV-WSN) and Dicer’s cofactor TAR-RNA binding protein (TRBP). We found that the N-terminal RNA binding domain (RBD) of NS1 and the first two domains of TRBP protein mediated this interaction. Furthermore, two amino acid residues (Arg at position 38 and Lys at position 41) in NS1 were essential for the interaction. We generated TRBP knockout cells and found that NS1 instead of NS1 mutants (two-point mutations within NS1, R38A/K41A) inhibited the process of microRNA (miRNA) maturation by binding with TRBP. PR8-infected cells showed masking of short hairpin RNA (shRNA)-mediated RNAi, which was not observed after mutant virus-containing NS1 mutation (R38A/K41A, termed PR8/3841) infection. Moreover, abundant viral small interfering RNAs (vsiRNAs) were detected in vitro and in vivo upon PR8/3841 infection. We identify, for the first time, the interaction between NS1 and TRBP that affects host RNAi machinery.

Analysis of gene expression in the lung of influenza virus infected C57BL/6 mice

Project description:We employ cDNA microarry(Agilent Mouse lncRNA (4*180K,Design ID:049801) ) to detect the differential expression of mRNAs and lncRNAs in the lung of mice infected with or without A/WSN/33 influenza virus. Microarry analysis revealed that 2092 mRNAs and 1640 lncRNAs differentially expressed in the lung of IAV infected mice compared to control,including 1399 mRNAs and 1052 lncRNAs upregulated, 693 mRNAs and 588 lncRNAs downregulatded. Our finding indicates that thousands of genes are involved in and may play critical roles in the influenza virus-host interactions.

Small RNA sequencing of HCV infected hepatoma cells

Project description:HCV infection requires both virus and host factors, including endogenous genes, a large proportion of which are noncoding RNAs (ncRNAs). The identification and mechanistic elucidation of these stably and conservatively expressed RNAs will shed light on HCV gene diagnosis and therapy. Nevertheless, most studied ncRNAs in HCV are microRNAs, with numerous other types of ncRNAs being neglected, such as long noncoding RNAs (lncRNAs) or small nucleolar RNAs (snoRNAs). Here, using two different hepatoma cell lines, we performed small RNA sequencing and analyzed the differential expression of microRNAs and snoRNAs, which provide data for further functional validation of snoRNAs and microRNAs during HCV infection.
