Plateletactivating factor (PAF) is a key mediator in pathogenesis of inflammatory bowel diseases (IBDs) but mechanisms of PAF-induced mucosal injury are poorly understood. To determine whether apoptosis and the Bcl-2-family of apoptosis regulatory gene products play a role in PAF-induced mucosal injury, we stably and conditionally overexpressed bcl-2 in rat small intestinal epithelial cells-6 u...

We used the plasmid vector pGEX-2T for the expression of recombinant subunits of Shiga-like toxin II (SLT-II). The 5' terminus of the genes that code for either the SLT-IIA or SLT-IIB subunits was genetically fused to the 3' terminus of the gene coding for the enzyme glutathione S-transferase, which serves as a carrier in this expression system. The subunit genes were constructed synthetically ...

The RUS (ROOT UVB SENSITIVE 1) proteins characterized by their unique DUF647 domain are widely distributed in eukaryotes. Their functional roles largely unknown except for the possible involvement of Arabidopsis RUS1 and RUS2 early seedling development. To investigate biochemical proteins, full length truncated were seamlessly fused with GFP cloned into prokaryotic expression vector pQE-100 whi...

Trichoderma reesei is a high-yield producer of cellulase for applications in lignocellulosic biomass conversion, but its production requires induction. A mixture glucose and β-disaccharide has been demonstrated to achieve high-level production. However, as inducers, β-disaccharides are prone be hydrolyzed by β-glucosidase (BGL) during fermentation, therefore need supplemented through feeding ov...

Diacylglycerol acyltransferase (DGAT) is the rate-limiting enzyme in triacylglycerol biosynthesis in eukaryotic organisms. Triacylglycerols are important energy-storage oils in plants such as peanuts, soybeans and rape. In this study, Arachis hypogaea type 2 DGAT (AhDGAT2) genes were cloned from the peanut cultivar 'Luhua 14' using a homologous gene sequence method and rapid amplification of cD...

Thioredoxin, a redox active protein, has been previously demonstrated to be essential for growth of the anoxygenic photosynthetic bacterium Rhodobacter sphaeroides. In the present study, the involvement of thioredoxin in the formation of the photosynthetic apparatus of R. sphaeroides WS8 was investigated by construction and analysis of a mutant strain disrupted for the chromosomal trxA copy and...

BACKGROUND ArtinM is a d-mannose-specific lectin from Artocarpus integrifolia seeds that induces neutrophil migration and activation, degranulation of mast cells, acceleration of wound healing, induction of interleukin-12 production by macrophages and dendritic cells, and protective T helper 1 immune response against Leishmania major, Leishmania amazonensis and Paracoccidioides brasiliensis inf...

Expression of HTLV-I p19 protein in an Escherichia coli expression system always leads to the formation of inclusion body. Solubilisation and refolding of the inclusion bodies is complex, time consuming and difficult during large-scale preparation. This study aimed to express and purify a soluble form of recombinant HTLV-I p19 protein in an E. coli expression system. The synthetic DNA encoding ...
