Higher antiviral response of RIG-I through enhancing RIG-I/MAVS-mediated signaling by its long insertion variant in zebrafish.

As an intracellular pattern recognition receptor (PRR), the retinoic acid-inducible gene-I (RIG-I) is responsible for the recognition of cytosolic viral nucleic acids and the production of type I interferons (IFNs). In the present study, an insertion variant of RIG-I with 38 amino acids inserted in the N-terminal CARD2 domain, as well as the typical type, named as RIG-Ia and RIG-Ib respectively were identified in zebrafish. RIG-Ia and RIG-Ib were all up-regulated following the infection of a negative ssRNA virus, the Spring Viremia of Carp Virus (SVCV), and an intracellular Gram-negative bacterial pathogen Edwardsiella tarda, indicating the RLR may have a role in the recognition of both viruses and bacteria.

Permanent genetic resources added to molecular ecology resources database 1 April 2013-31 May 2013.

This article documents the addition of 234 microsatellite marker loci to the Molecular Ecology Resources Database. Loci were developed for the following species: Acipenser sinensis, Aleochara bilineata, Aleochara bipustulata, Barbus meridionalis, Colossoma macropomum, Delia radicum, Drosophila nigrosparsa, Fontainea picrosperma, Helianthemum cinereum, Liomys pictus, Megabalanus azoricus, Pelteobagrus vachelli, Pleuragramma antarcticum, Podarcis hispanica type 1A, Sardinella brasiliensis and Sclerotinia homoeocarpa. These loci were cross-tested on the following species: Acipenser dabryanus, Barbus balcanicus, Barbus barbus, Barbus cyclolepis, Drosophila hydei, Drosophila melanogaster, Drosophila obscura, Drosophila subobscura, Fontainea australis, Fontainea fugax, Fontainea oraria, Fontainea rostrata, Fontainea venosa, Podarcis bocagei, Podarcis carbonelli, Podarcis liolepis, Podarcis muralis and Podarcis vaucheri.

Conservation and variation in mitochondrial genomes of gastropods Oncomelania hupensis and Tricula hortensis, intermediate host snails of Schistosoma in China.

The complete mitochondrial genomes of intermediate host snails for Schistosoma in China were sequenced, including the sub-species Oncomelania hupensis hupensis in two types, and O. hupensis robertsoni, intermediate hosts for S. japonicum, and Tricula hortensis, the intermediate host of S.

[Infectious bovine rhinotracheitis viral gG expression and gG-ELISA development].

Taking the genome DNA of Infectious Bovine Rhinotracheitis Virus (IBRV) as the template, the gG gene was amplified with PCR and cloned into the T cloning vector pMD18-T. After being identified by restriction digestion and DNA sequencing, the insert was subcloned into the expression vector pGEX-KG. Sodium docecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot assay showed that this gene was expressed as both soluble form and inclusion body by the transformed E.
