(Submitter supplied) Influenza A virus (IAV) is a human respiratory pathogen that causes yearly global epidemics, and sporadic pandemics due to human adaptation of pathogenic strains. Efficient replication of IAV in different species is, in part, dictated by its ability to exploit the genetic environment of the host cell. To investigate IAV tropism in human cells, we evaluated the replication of IAV strains in a diverse subset of epithelial cell lines. more...

(Submitter supplied) Recently, a novel protein in the influenza virus segment 3 has been identified, namely PA-X. This small protein has been reported to play a role in modulating host response of the 1918 H1N1 pandemic virus-infected mice. However, poteinal role of this protein in the pathogenicity and regulating host response of the highly pathogenic H5N1 virus in a chicken animal model is completely unknown. We used microarray analysis to evaluate the global transcriptional response in the lungs of the chickens infected with the parental strain (CK10) and PA-X deficiency mutant strain (CK-PAX3).

(Submitter supplied) The highly pathogenic avian influenza (HPAI) H5N1 viruses continue to circulate in nature and threaten public health. Although several viral determinants and host factors that influence the virulence of HPAI H5N1 viruses in mammals have been identified, the detailed molecular mechanism remains poorly defined and requires further clarification. In our previous studies, we characterized two naturally isolated HPAI H5N1 viruses that had similar viral genomes but differed substantially in their lethality in mice. more...

(Submitter supplied) Negative-sense RNA viruses (NSVs) rely on prepackaged viral RNA-dependent RNA polymerases (RdRp) to replicate and transcribe their viral genomes. Their replication machinery consists of an RdRp bound to viral RNA which is wound around a nucleoprotein (NP) scaffold, forming a viral ribonucleoprotein complex. NSV NP is known to regulate transcription and replication of genomic RNA, however its role in maintaining and protecting the viral genetic material is unknown. more...

(Submitter supplied) Analysis of gene expression level in a mouse tumorigenic phthalate, DEHP vs non-tumorigenic DNOP. The hypothesis tested in the present study was to identify early key event thresholds related to tumor outcomes in a two-year carcinogenicity bioassay. Our results highlight marked differences in the toxicity profiles of structurally similar phthalates and demonstrate quantitative relationships between early bioindicators and later tumor outcomes.

(Submitter supplied) A novel avian-origin H7N9 influenza A virus (IAV) emerged in China in early 2013 causing mild to lethal human respiratory infections. H7N9 originated from multiple reassortment events between avian viruses and carries genetic markers of human adaptation. Determining whether H7N9 induces a host-response closer to human or avian IAV is important to better characterize this emerging virus. Here we compared the human lung epithelial cell response to infection with A/Anhui/01/13 (H7N9) or highly pathogenic avian-origin H5N1, H7N7, or human seasonal H3N2 IAV.

(Submitter supplied) Occasional transmission of highly pathogenic avian H5N1 influenza viruses to humans causes severe pneumonia with high mortality. To better understand the mechanisms via which H5N1 viruses induce severe disease in humans, we infected cynomolgus macaques with six different H5N1 strains isolated from human patients and compared their pathogenicity and the global host responses to the virus infection. Although all H5N1 viruses replicated in the respiratory tract, there was substantial heterogeneity in their replicative ability and in the disease severity induced, which ranged from asymptomatic to fatal. more...

(Submitter supplied) Human disease caused by highly pathogenic avian influenza (HPAI) H5N1 can lead to a rapidly progressive viral pneumonia leading to acute respiratory distress syndrome. There is increasing evidence suggests a role for virus-induced cytokine dysregulation in contributing to the pathogenesis of human H5N1 disease. The key target cells for the virus in the lung are the alveolar epithelium and alveolar macrophages, and previous data has shown that compared to seasonal human influenza viruses, equivalent infecting doses of H5N1 viruses markedly up-regulate pro-inflammatory cytokines in both primary cell types in vitro. more...

Analysis of macrophages at 1, 3, and 6 hours post-infection with H1N1 or H5N1 viruses in vitro. The avian H5N1 virus is highly pathogenic, while the swine H1N1 virus is less so. Alveolar macrophages are targets of H5N1. Results provide insight into the host response to H1N1 and H5N1 infections.

(Submitter supplied) 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.

(Submitter supplied) MicroRNA-203 was up-regulated markedly upon H5N1 virus infection. To identify the potential target genes of miR-203, we constructed a miR-203 knockout A549 cell line. Then wild-type and miR-203 knockout A549 cells were mock-infected or infected with H5N1 virus for 48h. The Agilent Whole Human Genome Oligo Microarray was performed to analyze the mRNA expression profiling. Meanwhile, the online tool TargetScanHuman (http://www.targetscan.org/vert_71/) was used to predict biological targets of miR-203. more...
