SOX9 is a member of the SOX [Sry-related high-mobility group (HMG) box] family and is required for the development and differentiation of multiple cell lineages. To clarify the significance of SOX9 in gastric carcinoma (GC), immunohistochemical expression of SOX9 and the CpG island methylation status of SOX9 were evaluated and compared with(More)
Newcastle disease (ND) is an OIE listed disease caused by virulent avian paramyxovirus type 1 (APMV-1) strains, which is enzootic and causes large economic losses in the poultry sector. Genotype VII and genotype IX NDV viruses were the predominant circulating genotype in China, which may possibly be responsible for disease outbreaks in chicken flocks in(More)
Newcastle disease virus (NDV) is the causative agent of Newcastle disease, which is characterized by inflammatory pathological changes in the organs of chickens. The inflammatory response to this disease has not been well characterized. Previous reports showed that the sphingosine-1-phosphate-1 receptor (S1PR1), a G protein-coupled receptor, is important to(More)
Though previous studies have identified two strains of duck-origin Newcastle disease virus (NDV) with varying levels of pathogenicity, the relationship between the early-phase host innate immune response, and pathogenesis of ducks infected with these strains in the lungs and thymuses remains unclear. In this study, we compared the viral distribution and(More)
Riemerella anatipestifer is a pathogenic bacterium that has spread all over the world and is associated with epizootic infections in waterfowl and other avian species. R. anatipestifer RA-SG is an avirulent strain, isolated from an infected duck in Guangdong province, China. The genome sequence of this species is presented herein.
Egg-laying duck flocks in Guangdong province, southern China, have been suffering a widely spreading infectious disease with abrupt egg drops and death since the winter of 2010. However, the causative pathogen was not known. We obtained two independent virus isolates named FS and JM from the diseased layer duck flocks and identified them as duck-origin(More)
Goose/GD/2010 is a newly emerging Newcastle disease virus (NDV) isolated from a sick goose flock in southern China. Here, we report the complete genome sequence of this isolate, which belongs to NDV subgenotype VIIb. This is the first report about the complete genome information of an isolate of subgenotype VIIb in China.
Interferon regulatory factor 7 (IRF7) is essential for the induction of an antiviral response. Previous studies have shown that virus replication causes the activation or expression of Type I interferon (IFN) in cells, which further activates IFN-stimulated genes (ISGs) to retard virus growth. In this study, after infection of chicken embryo fibroblasts(More)
A new family of IFNs called type III IFN or IFN-λ has been described, and shown to induce antiviral activity against several viruses in the cell culture. In this study, the molecular cloning, expression, and antiporcine epidemic diarrhea virus (PEDV) activity of porcine IFN-λ3 (poIFN-λ3) were reported. The full-length poIFN-λ3 cDNA sequence encoded 196(More)
Extraintestinal pathogenic Escherichia coli (ExPEC) can invade and colonize multiple extraintestinal tissues and can cause a wide range of infections; however the mechanisms of its pathogenicity are not well understood. Flagella contribute to the infection of E. coli strains by mediating adhesion and invasion. Our previous bioinformatic analysis revealed(More)
