objective(s): up to now, many researches have been performed to improve the antitumoral effect of melanoma differentiation-associated gene-7 (mda-7) protein. the purpose of our research was to construct 3 expression vectors producing mda-7 in fusion with rgd (arginine-glycine-aspartic acid) peptide and evaluate their expression. materials and methods: mda-7 gene with two different rgd seque...
chicken infectious bronchitis virus (ibv) causes severe respiratory and renal dysfunction in chickens. in the present study, we used reverse transcription-polymerase chain reaction (rt-pcr) to amplify the nucleocapsid (n) protein gene of strain massachusetts (mass) h120 of ibv that is commonly used in the vaccine production in iran. the pcr product with the expected size of 1.2 kb was cloned in...
Cloning and expression of the L-phenylalanine dehydrogenase gene, from B. sphaericus in E. coli were done. The gene was cloned in the vector pET16b and transformed into E. coli BL21 (DE3). The functional form of the L-phenylalanine dehydrogenase enzyme was purified by affinity purification techniques, taking advantage of the ability of this enzyme to bind to the nucleotide site affinity dye, Re...
Introduction: Following the first description of multiple myeloma (MM), as the second most prevalent hematologic malignancy, multiple promising advances have paved the way to increase the long-lasting complete remission for patients. In the era of the novel therapeutic approaches, the cloning of the apoptosis-inducing genes into the genome of malignant cells has attracted tremendous attention. ...
Background: Outer inflammatory protein A (OipA) is one of the important adhesins of H. pylori and a valuable candidate for vaccine development. Its gene is under "on-off" switch status which correlates with OipA protein expression. Objectives: We aimed to obtain a recombinant OipA clone (with "on" status) from an Iranian clinical isolate. Materials and Methods: A clinical H. pylori-isolate demo...
background: rh (rhesus) is a highly complex blood group system in man deeply rooted in transfusion medicine. isolation of rhd from cord blod, cloning and expression of recombinant rhd antigen in bacterial expression system was the aim of this study. methods: total rnas were extracted from cord blood (o + ). the quality of rna was determined by electrophoresis. in order to obtain coding sequen...
background: echinococcosis or hydatidosis is a chronic, zoonotic worldwide infection that occurs by the larval stages of taeniid cestodes of the genus echinococcus . iran is known as endemic region for this infection in the world. vaccination has been considered as a good prevention method for this disease. recombinant vaccines containing eg95 protein, against e. granulosus , has shown a high d...
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...
Introduction:Toxoplasma gondii is a ubiquitous obligate intracellular parasite with a relatively broad host range infecting both mammals and birds. Toxoplasma proteins are strong antigens that can begin strong immune reactions, among which Rhoptry protein 1 (ROP1) can be named discharging from rhoptry cell-organ. ROP1 is regarded as a competitor for recombinant vaccines against toxoplasmosis. T...
Background and purpose: Toxoplasmosis is a common parasitic disease throughout the world and one-third of the population has antibodies to Toxoplasma gondii. This disease causes serious medical problems in fetuses and immunocompromised individuals. As gene encoding protein GRA14 can be considered as a suitable target for DNA vaccine and designing diagnostic kits the aim of this study was to ...
