Homeobox genes encode transcription factors which play important roles in the developmental processes of many multicellular organisms. TGIFLX/Y (TGIFLX and TGIFLY) are members of the homeobox superfamily of genes. Their expressions are specifically detected in the human adult testis but their functions are remained to be investigated. In this investigation we cloned full length of TGIFLY cDNA a...

objective: development of high producing mammalian cell lines is a major bottleneck in manufacturing of recombinant therapeutic proteins. this study examines the effect of using the matrix attachment region from the human interferon beta gene in combination with promoter activation strategy with e1a 13s protein on human tissue plasminogen activator (t-pa) expression in chinese hamster ovary (ch...

background: the humbug gene is a truncated isoform of aspartyl β-hydroxylase (asph) gene that is overexpressed in many human malignancies. in recent years, since humbug has received increasing attention, it is considered as a potential therapeutic molecular target. therefore, it is necessary for preparing humbug protein and its monoclonal antibody to investigate its structure and function. meth...

BACKGROUND Human BiP is traditionally regarded as a major endoplasmic reticulum (ER) chaperone performing a number of well-described functions in the ER. In recent years it was well established that this molecule can also be located in other cell organelles and compartments, on the cell surface or be secreted. Also novel functions were assigned to this protein. Importantly, BiP protein appears ...

Bacterial expression systems provide economic and logistic advantages in manufacturing proteins for human therapeutic purposes. However, most such proteins accumulate in insoluble biologicaIIy inactive form when overexpressed in bacterial cells. This is the case while attempting to produce recombinant human granulocyte-macrophage colony stimulating factor (hGM-CSF) in E. coli. In this repor...

objective(s): streptokinase (ska) is an antigenic protein which is secreted by streptococcus pyogenes. streptokinase induces inflammation by complement activation, which may play a role in post infectious diseases. in the present study, recombinant streptokinase from s. pyogenes was produced and showed that recombinant ska protein was recognized by infected human sera using western blot analysi...

Background: Thrombopoietin (TPO) is an important cytokine that has a critical role in regulating hematopoietic stem cells (HSCs) proliferation and megakaryocyte differentiation. Because of scares amount of this protein in human plasma, in many biotechnological centers around the world, recombinant production of this protein has been carried out. This study was aiming to gene cloning and express...

The recombinant antibodies AC650, AC653, AC656 and AD460 detect by immunofluorescence the human CD8α protein.

Background and Aims: Enzybiotics are probably the future line of weapons against drug resistant bacteria. They lyse bacteria with the new mechanisms with few likelihood of generating resistance. LasA, which is secreted from Pseudomonas strains degrades Staphylococcus aureus (S. aureus) cell wall and has the potential to use against drug resistant S. aureus infections.  Materials and Metho...
