Infectious bursal disease virus (IBDV) is a bi-segmented, double-stranded RNA virus which belongs to the genus Avibirnavirus of the family Birnavirideae. In this study, we determined the complete nucleotide sequences of a reassortment IBDV strain TL2004 with segments A and B derived from attenuated and very virulent strains of IBDV. This strain is(More)
Smyd1b is a member of the Smyd family that is specifically expressed in skeletal and cardiac muscles. Smyd1b plays a key role in thick filament assembly during myofibrillogenesis in skeletal muscles of zebrafish embryos. To better characterize Smyd1b function and its mechanism of action in myofibrillogenesis, we analyzed the effects of smyd1b knockdown on(More)
The gene encoding the oligopeptide transporter PepT1 (HGMW-approved gene symbol SLC15A1) from Tibetan porcine intestine was cloned. The open reading frame of this cDNA encodes 708 deduced amino acid residues that show high sequence similarity with its ovine and bovine counterparts. The putative protein has 12 putative transmembrane domains, including many(More)
The small intestine is the main absorption place of peptides and free amino acids in mammals. The amino acid transporter system b(0,+) mediates apical uptake of basic amino acids, especially lysine, arginine and cysteine. The aim of the current study was to clone Tibetan porcine amino acid transporter b(0,+)AT (SLC7A9) for comparing the sequences of Tibetan(More)
Vibrio alginolyticus is one of the Vibrio pathogens common to humans and marine animals. During infection and induction of the host immune response, outer membrane proteins of bacteria play an important role. In this study, an outer membrane protein gene (ompW) was cloned from V. alginolyticus and expressed in Escherichia coli. The 645 bp open reading frame(More)
Sinocyclocheilus furcodorsalis, a typical cavefish, has evolved some striking characters, for example loss of its eyes and reduction in melanin pigmentation, and can serve as a good model system in evolutionary adaptation developmental mechanisms. So we cloned the complete mitochondrial DNA of S. furcodorsalis (16,581 bp), which is similar to those reported(More)
BACKGROUND Smyd1b is a member of the Smyd family that plays a key role in sarcomere assembly during myofibrillogenesis. Smyd1b encodes two alternatively spliced isoforms, smyd1b_tv1 and smyd1b_tv2, that are expressed in skeletal and cardiac muscles and play a vital role in myofibrillogenesis in skeletal muscles of zebrafish embryos.

Weanling mammals (including infants) often experience intestinal dysfunction when fed a high-protein diet. Recent work with the piglet (an animal model for studying human infant nutrition) shows that reducing protein intake can improve gut function during weaning but compromises the provision of essential amino acids (EAA) for muscle growth. The present(More)
The objective of this study was to determine developmental changes in mRNA and protein levels for N-acetylglutamate synthase (NAGS; a key enzyme in synthesis of citrulline and arginine from glutamine/glutamate and proline) in the small intestine of suckling piglets. The porcine NAGS gene was cloned using the real-time polymerase-chain reaction (RT-PCR)(More)
Lactoferrin has antimicrobial activity associated with peptide fragments lactoferricin (LFC) and lactoferrampin (LFA) released on digestion. These two fragments have been expressed in Photorhabdus luminescens as a fusion peptide linked to protein cipB. The construct cipB-LFC-LFA was tested as an alternative to antimicrobial growth promoters in pig(More)
