Recombinant plectasin, the first fungus defensin, was expressed in Pichia pastoris and purified, and its physical, chemical and antimicrobial characteristics were studied. Following a 120 h induction of recombinant yeast, the amount of total secreted protein reached 748.63 μg/ml. The percentage of recombinant plectasin was estimated to be 71.79% of the(More)
A novel specifically targeted antimicrobial peptide (STAMP) that was especially effective against methicillin-resistant Staphylococcus aureus (MRSA) was designed by fusing the AgrD1 pheromone to the N-terminal end of plectasin. This STAMP was named Agplectasin, and its gene was synthesized and expressed in Pichia pastoris X-33 via pPICZαA. The highest(More)
Members of Myxozoa, a parasitic metazoan taxon, have considerable detrimental effects on fish hosts and also have been associated with human food-borne illness. Little is known about their biology and metabolism. Analysis of the genome of Thelohanellus kitauei and comparative analysis with genomes of its two free-living cnidarian relatives revealed that T.(More)
The expression of the genomic information of severe acute respiratory syndrome coronavirus (SARS CoV) involves synthesis of a nested set of subgenomic RNAs (sgRNAs) by discontinuous transcription. In SARS CoV-infected cells, 10 sgRNAs, including 2 novel ones, were identified, which were predicted to be functional in the expression of 12 open reading frames(More)
Anti-Thy1 glomerulonephritis is a rat nephritis model closely simulating human mesangial proliferative glomerulonephritis. It affects primarily the mesangium, yet displays substantial proteinuria during the course. This study investigated the molecular signals underlying proteinuria in this disease and the modulation of which by the known antiproteinuric(More)
The targeting of a cellular co-factor, rather than the HIV-1-specific RNAs, by small interfering RNAs holds promise as the rapid mutational ability of the HIV-1 genome may obviate the potential clinical use of RNAi against this virus. The DEAD-box RNA helicase DDX3 is an essential Rev co-factor in the CRM1-Rev-RRE complex that promotes the export of(More)
We investigated the effects of incorporating chitinase (ChiB565)-hydrolyzed shrimp shell chitin into the diet of hybrid tilapia (Oreochromis niloticus ♀ × Oreochromis aureus ♂) with regard to production, intestinal immune status and autochthonous gut bacteria, and protection against bacterial pathogen Aeromonas hydrophila. Five experimental diets were(More)
The investigation of the recombinant bovine lactoferrin-derived antimicrobial protein (rBLfA) demonstrates that the inter-lobe region of bovine lactoferrin contributes to iron binding stability and antimicrobial activity against Staphylococcus aureus. rBLfA containing N-lobe (amino acid residues 1–333) and inter-lobe region (residues 334–344) was expressed(More)
To detect the soybean allergen P34 (Gly m Bd 30K) from soybean products, the full-length cDNA sequence of P34 was synthesized and inserted into the prokaryotic expression vector pET-28a. The P34 protein was expressed in Escherichia coli BL21 (DE3) as an inclusion body under the induction of 0.8 mmol/L isopropyl β-d-1-thiogalactopyranoside. After(More)
A plasmid was constructed for quantification of genetically modified (GM) cottonseed meal in the gene-specific level. The Cry1Ab/c gene was connected with the Sad1 gene by fusion PCR. The fusion gene was cloned into the pMD®19-T Simple Vector. The plasmid DNA was then digested with a restriction endonuclease SmaI to reduce the characteristic differences(More)
