background and objectives: the toxin co-regulated pilus a (tcpa) has been described as a criti- cal pathogenicity factor of vibrio cholerae . tcpa is a candidate for making subunit vaccine against chol- era. the aim of this study was to produce a candidate vaccine by expressing recombinant tcpa in e. coli . materials and methods: i...
BACKGROUND Recently, the anti-tumor activity of N-myc downstream-regulated gene 2 (NDRG2) was shown decreased expression in clear cell renal cell carcinoma (CCRCC), but the role of the down-expression of NDRG2 has not been described. METHODS The NDRG2 recombinant adenovirus plasmid was constructed. The proliferation rate and NDRG2 expression of cell infected with recombinant plasmid were mesu...
background: various prokaryotic and eukaryotic expression systems have been developed for the production of recombinant proteins. in the present study, we used a new protein expression system based on the iranian lizard leishmania, a trypanosomatid protozoan as a host, for the expression of lpg3 gene from leishmania infantum (l.infantum). methods: the lpg3 gene was cloned in the expression cass...
human growth hormone (hgh) is a protein with multiple roles in a range of biological functions such as protein, carbohydrates and lipid metabolisms as well as immunity, tissue development and overall growth. one of the major class of biopharmaceuticals in mammalian cells is the production of recombinant pharmaceutical proteins. in this study, we constructed a lentiviral vector carrying coding r...
background and objective: use of elastin-like proteins (elps) provides high-performance protein purification without need for chromatography. in line with cost reduction and facilitation of recombinant proteins purification, which represent a high percentage of production costs, in this project, we eliminated the need for proteases in the process of separation of recombinant proteins from elp b...
Telomerase is a multi-subunit enzyme that reverse transcribes telomere repeats onto the ends of linear eukaryotic chromosomes and is therefore critical for genome stability. S. cerevisiae telomerase activity is cell-cycle regulated; telomeres are not elongated during G1 phase. Previous work has shown that Est1 protein levels are low during G1 phase, preventing telomerase complex assembly. Howev...
Bevacizumab, a recombinant humanized monoclonal antibody, binds vascular endothelial growth factor (VEGF) and inhibits its interaction with receptors found on endothelial cells. Bevacizumab has been increasingly used as an off-label treatment for exudative age-related macular degeneration (AMD). Whether or not bevacizumab is capable of arresting t...
background: rabies virus (rabv) is a deadly neurotropic virus that causes the disease of rabies in humans and animals. l protein is one of the large structural protein of rabies virus, which displays multiple enzymatic activities, and is required for viral transcription and replication.objectives: a truncated l protein of rabies virus is being cloned, expressed and purified to produce relevant ...
BACKGROUND Inducible high-level expression is favoured for recombinant protein production in Pichia pastoris. Therefore, novel regulated promoters are desired, ideally repressing heterologous gene expression during initial growth and enabling it in the production phase. In a typical large scale fed-batch culture repression is desired during the batch phase where cells grow on a surplus of e.g. ...
background: staphylococcus aureus (s. aureus) is a major nosocomial pathogen and the infection with this organism in human is increasing due to the spread of antibiotic resistant strains. one of the resistance mechanisms of s. aureus comprises modification in binding proteins to penicillin. vaccine strategy may be useful in controlling the infections induced by this organism. this study aimed a...
