Cells sense several kinds of stimuli and trigger corresponding responses through signaling pathways. As a result, cells must process and integrate multiple signals in parallel to maintain specificity and avoid erroneous cross-talk. In this study, we focus our theoretical effort on understanding specificity of a model network system in yeast, Saccharomyces(More)
The investigation of the dynamics and regulation of virus-triggered innate immune signaling pathways at a system level will enable comprehensive analysis of the complex interactions that maintain the delicate balance between resistance to infection and viral disease. In this study, we developed a delayed mathematical model to describe the virus-induced(More)
The early diagnosis and investigation of the pathogenic mechanisms of complex diseases are the most challenging problems in the fields of biology and medicine. Network-based systems biology is an important technique for the study of complex diseases. The present study constructed dynamic protein-protein interaction (PPI) networks to identify dynamical(More)
Robustness, the ability to maintain performance in the face of perturbations and uncertainty, is believed to be a necessary property of biological systems. In this paper, we address the issue of robustness in an important signal transduction network--epidermal growth factor receptor (EGFR) network. First, we analyze the robustness in the EGFR signaling(More)
We describe an alternative reverse genetics system for generating classical swine fever virus (CSFV) based on swine RNA polymerase I promoter (pSPI)-mediated vRNA transcription. The recombinant plasmid pSPTI/SM harboring a full-length CSFV Shimen strain cDNA, flanked by a swine RNA polymerase I (pol I) promoter sequence at the 5′ end and a murine pol I(More)
We report here the complete genome sequence of virulent fowl adenovirus serotype 4 strain HB1510, isolated from a diseased chicken with hydropericardium-hepatitis syndrome in Hubei, China, in 2015. The viral genome is 43,721 bp long, and sequence analysis showed an 11-amino-acid deletion in open reading frame 29 (ORF29).
Thermostable Newcastle disease virus (NDV) vaccines have been used widely to protect village chickens against Newcastle disease, due to their decreased dependence on cold chain for transport and storage. However, the genetic basis underlying the NDV thermostability is poorly understood. In this study, we generated chimeric viruses by exchanging viral genes(More)
The role of endoplasmic reticulum (ER) stress in Japanese encephalitis is largely unknown. In this study, we found that Japanese encephalitis virus (JEV) strain SA14-14-2 regulates the expression of glucose-regulated protein 78 (GRP78), transcription factor 4 (ATF4) and C/EBP homologous protein (CHOP), and splicing of X-box-binding protein 1 (XBP1) mRNA in(More)
Respiratory syncytial virus (RSV) infection upregulates genes of the suppressor of cytokine signaling (SOCS) family, which utilize a feedback loop to inhibit type I interferon dependent antiviral signaling pathway. Here, we reconstituted RSV nonstructural (NS) protein expression plasmids (pNS1, pNS2, and pNS1/2) and tested whether NS1 or NS2 would trigger(More)
