The Bombyx mori fibroin light (L)-chain gene was cloned and the green fluorescent protein (GFP) gene inserted into exon 7. The chimeric L-chain-GFP gene was used to replace the polyhedrin gene of Autographa californica nucleopolyhedrovirus (AcNPV). This recombinant virus was used to target the L-chain-GFP gene to the L-chain region of the silkworm genome. Female moths were infected with the rec...

background: enterotoxigenic escherichia coli (etec) strains are the major causes of diarrheal disease in humans and animals. colonization factors and enterotoxins are the major virulence factors in etec pathogenesis. for the broad-spectrum protection against etec, one could focus on colonization factors and non-toxic heat labile as a vaccine candidate. methods: a fusion protein is composed of a...

p28 and nrc peptides are two anticancer peptides with various mechanisms have shown to be effective against breast cancer. therefore, it seems that construction of a chimeric protein containing the two peptides might cause synergistic cytotoxic effects. however, since the two peptides bear opposite charges, production of a chimeric protein in which the two moieties do not intervene each other i...

Foot and Mouth Disease (FMD) is a very dangerous livestock disease which causes a serious loss in the production of milk and meat. Therefore, producing an effective recombinant subunit vaccine virus this disease is of great importance. Transient gene expression is a valuable tool to reach rapid and acceptable recombinant vaccine. An Agrobacterium-mediated transient gene expression assay was car...

Horizontal gene transfer (HGT) often leads to phylogenetic incongruence. When "duplicative HGT" introduces a second copy of a pre-existing gene, the two copies may then engage in gene conversion, leading to phylogenetically mosiac genes. When duplicative HGT is followed by differential gene conversion among descendant lineages, as under the DH-DC model, phylogenetic analysis is further complica...

In this research, we developed a novel chimeric HTNV-IL-2-G2 DNA vaccine plasmid by genetically linking IL-2 gene to the G2 segment DNA and tested whether it could be a candidate vaccine. Chimeric gene was first expressed in eukaryotic expression system pcDNA3.1 (+). The HTNV-IL-2-G2 expressed a 72 kDa fusion protein in COS-7 cells. Meanwhile, the fusion protein kept the activity of its parenta...
