1. Application of n-dodecane as an oxygen vector to enhance the activity of fumarase in recombinant Escherichia coli: role of intracellular microenvironment
Abstract The effect of the intracellular microenvironment in the presence of an oxygen vector during expression of a fusion protein in Escherichia coli was studied. Three organic solutions at different concentration were chosen as oxygen vectors for fumarase expression. The addition of n-dodecane did not induce a significant change in the expression of fumar

2. Parenteral adjuvant potential of recombinant B subunit of Escherichia coli heat-labile enterotoxin
BACKGROUND The B subunit of Escherichia coli heat-labile enterotoxin (LTB) is a potent mucosal immune adjuvant. However, there is little information about LTB's potential as a parenteral adjuvant. OBJECTIVES We aimed at evaluating and better understanding rLTB's potential as a parenteral adjuvant using the fused R1 repeat of Mycoplasma hyopneumoniae P97 ad

3. Expression, Purification and Functional Assessment of Smallest Isoform of Human Interleukin-24 in Escherichia coli
ABSTRACT Interleukin-24 (IL-24) is a novel tumor-suppressor gene that has different alternative splice isoforms. It has been shown that new smallest isoform of human IL-24 gene, lacking three exons, induces higher levels of cytotoxicity than all the isoforms, indicating shortest isoform of IL-24 may be a new promising anti-cancer agent. In this study, we aim

4. Desenvolvimento de vetores não virais para entrega gênica baseados na cadeia leve de dineína Rp3 = : Development of non viral vectors for gene delivery based on dynein light chain Rp3 / Development of non viral vectors for gene delivery based on dynein light chain Rp3
Gene delivery is a promising technique with great medical potential that consists in the introduction of exogenous nucleic acids, and can be applied for gene therapy as well as DNA vaccination. However, its use is still limited by the lack of an ideal delivery vector, which is both safe and efficient. Although much more effective, viral vectors still raise s

5. Reprogramação de células mesenquimais de tecido adiposo em células-tronco pluripotentes por meio de proteína de fusão TAT / Nuclear reprogramming of adipose-tissue mesenchymal stem cells into pluripotent stem cells using TAT fusion protein
Os vírus são eficazes na transferência de genes em células devido aos seus mecanismos especializados. No entanto, vírus como veículos de entrega de genes podem acarretar em problemas, particularmente quando proposto para reprogramar células somáticas em células-tronco pluripotentes induzidas (iPS) visando utilização terapêutica. No presente estud

6. Cloning of a novel xylanase gene from a newly isolated Fusarium sp. Q7-31 and its expression in Escherichia coli
A strain of Q7-31 was isolated from Qinghai-Tibet Plateau and was identified as Fusarium sp. based on its morphological characteristics and ITS rDNA gene sequence analysis. It has the highest capacity of degrading cell wall activity compared with other 11 strains. To do research on its xylanase activity of Fusarium sp. Q7-31 while the degrading the rice cell

7. Expressão heteróloga de neurotoxinas do veneno da aranha Phoneutria nigriventer
The venom of the spider Phoneutria nigriventer contains several peptides that act on ion channels and receptors of the nervous system of insects and mammals. The toxins Tx3-6 and Tx3-4 are voltage-gated calcium channel blockers and have shown a pharmacological potential in the treatment of pain and in neuroprotection. Only small amounts of these toxins can b

8. Optimizing expression and purification of an ATP-binding gene gsiA from Escherichia coli k-12 by using GFP fusion
The cloning, expression and purification of the glutathione (sulfur) import system ATP-binding protein (gsiA) was carried out. The coding sequence of Escherichia coli gsiA, which encodes the ATP-binding protein of a glutathione importer, was amplified by PCR, and then inserted into a prokaryotic expression vector pWaldo-GFPe harboring green fluorescent prote

9. Expression of mouse beta defensin 2 in Escherichia coli and its broad-spectrum antimicrobial activity
Mature mouse beta defensin 2 (mBD2) is a small cationic peptide with antimicrobial activity. Here we established a prokaryotic expression vector containing the cDNA of mature mBD2 fused with thioredoxin (TrxA), pET32a-mBD2. The vector was transformed into Escherichia Coli (E. coli) Rosseta-gami (2) for expression fusion protein. Under the optimization of fer

10. TLR5-dependent immunogenicity of a recombinant fusion protein containing an immunodominant epitope of malarial circumsporozoite protein and the FliC flagellin of Salmonella Typhimurium
Recently, we described the improved immunogenicity of new malaria vaccine candidates based on the expression of fusion proteins containing immunodominant epitopes of merozoites and Salmonella enterica serovar Typhimurium flagellin (FliC) protein as an innate immune agonist. Here, we tested whether a similar strategy, based on an immunodominant B-cell epitope

11. Molecular cloning, characterization and enzymatic properties of a novel βeta-agarase from a marine isolate Psudoalteromonas sp. AG52
An agar-degrading Pseudoalteromonas sp. AG52 bacterial strain was identified from the red seaweed Gelidium amansii collected from Jeju Island, Korea. A β-agarase gene which has 96.8% nucleotide identity to Aeromonas β-agarase was cloned from this strain, and was designated as agaA. The coding region is 870 bp, encoding 290 amino acids and possesses charact

12. Molecular cloning and expression of key gene encoding hypothetical DNA polymerase from B. mori parvo-like virus
BmPLV-Z is the abbreviation for Bombyx mori parvo-like virus (China isolate). This is a novel virus with two single-stranded linear DNA molecules, viz., VD1 (6543 bp) and VD2 (6022 bp), which are encapsidated respectively into separate virions. Analysis of the deduced amino acid sequence of VD1-ORF4 indicated the existence of a putative DNA-polymerase with e
