Background: Chlamydomonas reinhardtii is a novel recombinant eukaryotic expression system with many advantages including fast growth rate, rapid scalability, absence of human pathogens and the ability to fold and assemble complex proteins accurately, however, obstacle relatively low expression level necessitates optimizing foreign gene expression in this system. The Green Fluorescent Protein (G...

Abstract Mitochondria contain an organellar genome that encodes for subunits of the respiratory chain. Its coordinated expression is essential eukaryotic life and defects in this process lead to severe disease. However, molecular mechanisms underlying mitochondrial gene remain poorly understood. Recent structural functional studies have provided first mechanistic insights into highlight evoluti...

background toxoplasmosis is an opportunistic protozoan infection with a high prevalence in a broad range of hosts infecting up to one-third of the world human population. toxoplasmosis leads to serious medical problems in immunocompromised individuals and fetuses and also induces abortion and mortality in domestic animals. therefore, there is a huge demand for the development of an effective va...

objective: rna interference (rnai) is the most potent technique for gene silencing in eukaryotic cellular system at transcriptomic level. genetic disorders and cancers are important targets for therapeutic development of this technique. in order to bypass the temporary dpwnregulation by sirna, a new generation of shrna named shrnamir has developed. silencing construct with structure similar to ...

We describe procedures for intracellular expression of scFv in eukaryotic cells. Starting from a scFv gene cloned in a phage-display vector, we describe the cloning step into a mammalian expression vector, the transient transfection of a HeLa cell line, and the monitoring of intrabody expression by immunofluorescence staining and FACS analysis.

chaperones are produced by prokaryotic, yeast and higher eukaryotic cells for various purposes. over-expression of each chaperone or sets of them affect the production level of a recombinant protein in the cell. on the basis of this hypothesis, five different plasmids with 5 different combinations of 6 chaperones molecule, transformed into escherichia coli along with human basic fibroblast grow...

background: dna vaccination with plasmid encoding bacterial, viral, and parasitic immunogens has been shown to be an attractive method to induce efficient immune responses. bacteria of the genus brucella are facultative intracellular pathogens for which new and efficient vaccines are needed. methods: to evaluate the use of a dna immunization strategy for protection against brucellosis, a plasmi...
