diagnosis of toxoplasma gondii (t.gondii) infection is of great medical importance especially for pregnant women and immunosuppressed patients. numerous studies have shown that the recombinant production of several ttoxoplasma antigens, including dense granule antigens (gras) has a great potential as diagnostic reagents. previous studies reported expression of amino terminal gra8 protein in fus...
Introduction: Plant ribosome inactivating proteins act as N-glycosidase enzyme and produce by several family of Caryophyllaceae such as Saponaria Officinalis. Different Isoforms of RIPs expressed by Saponaria Officinalis. SO6 isoform depurinate Adenine 4324 in the conserved GAGA loop of 28SrRNA and disrupts protein synthesis. The aim of this study was expression of SO6 isoform in E.coli and inv...
Background : Hepatitis C virus (HCV) is considered as one of the major pathogenic agents of chronic liver diseases. Previous studies have shown that HCV proteins can interaction with gene regulatory networks such as microRNAs. The aim of this study was to investigate the effect of HCV core protein on the expression of miR-150 in a cell culture model. Materials and Methods: Plasmids expressin...
Background and purpose: Human papillomavirus (HPV) is one of the infectious agents that causes genital and non-genital warts and skin cancers in humans. The E7 protein of this virus is one of the small oncoproteins that may be the main target in therapeutic vaccines. E7 protein with HIV-1 Tat peptide (49-59), plays a protective role that cause immune Th1 and CTLs response. The aim of this study...
background: improving the performance of hiv diagnosis assays is one of the most important ways to reduce hiv transmission. because of the high mutation rate of hiv, it is critical to use the conserved proteins to develop diagnostic immunoassay methods. because integrase is one of the most conserved proteins of hiv, it may be a good target for this purpose. in this paper cloning, purification a...
Background: Escherichia coli is still the common host for ing and heterologous protein expression. Various strategies have been employed to increase protein expression in E. coli, but, it seems that external factors such as selection marker concentration can drastically aff ect the yield of protein and plasmid.Objectives: Alterations of protein expression...
Introduction: Previous studies have shown altered levels of n-3LCPUFA in the pathophysiologcal conditions such as preeclampsia .Also elevated expression of sFlt-1 in preeclampsia plays a major role in the pathogenesis of this serious disorder especially in reduced placental oxygenation. The present study examines the hypothesis that Eicosapentaenoic acid (EPA 20:5), an omega-3 long-chain polyun...
Background: The purpose of this study was to clone, express, and purify a novel multidomain fusion protein of Micobacterium tuberculosis (Mtb) in a prokaryotic system. Methods: An hspX/esxS gene construct was synthesized and ligated into a pGH plasmid, E. coli TOP10 cells were transformed, and the vector was purified. The vector containing the construct and pET-21b (+) plasmid were digested ...
Brucella bacterium causes Brucellosis, an infectious disease spreading from animals to human. Brucella lumazine synthase (BLS) is a highly immunogenic protein with adjuvant properties, which has been introduced as an effective protein carrier for vaccine development. This protein also plays a significant role in inducing immune system. This study aimed to clone, express, and purify the BLS gene...
discoidin domain receptor (ddr) is a new member of the receptor tyrosine kinase family. there are two isoforms of discoidin domain receptor (ddr), ddr1 and ddr2. these receptors play a major role in the adhesion, motility and cell proliferation. due to the important role of ddr2 in the development of tumor extension, this receptor is pivotal in the field of carcinogenesis. the aim of this study...
