Background: Breast cancer is the most common female malignancy and the leading cause of cancer mortality in women worldwide. The human epidermal growth factor receptor2 (HER2) is a transmembrane tyrosine kinase receptor that is usually overexpressed in human breast cancers. Stable cell lines heterogeneously overexpressing HER2 are highly required as in vitro models for breast cancer research. T...

results the results showed that sensitivity and specificity were respectively 84.12% and 92% for‎ recombinant protein srs3 and 92% and 96% for rsag1. conclusions recombinant proteins srs3 and rsag1 are promising antigens in diagnostic assays for detection of specific antibodies against t. gondii. background infections by the protozoan parasite toxoplasma gondii (t. gondii) are widely prevalent ...

background: plants are among promising and suitable platform systems for production of recombinant biopharmaceutical proteins due to several features such as safety, no need for fermentation, inexpensive investment, and fast and easy scale-up. human insulin is one of the most widely used medicines in the world. up to now different expression systems including escherichia coli, yeast and cho hav...

background: echinococcosis or hydatid disease is a zoonotic infection caused by larval (metacestode) stages of cestodes belonging to the genus echinococcus, family taeniidae . we aimed to subclone antigen b gene in pqe-30 plasmid, its expression, and purification. methods: we subcloned hi gene into pqe-30 expression vector. the recombinant vector was transformed into e. coli , m15 and mass cult...

Retina ganglion cell (RGC) axons grow along a stereotyped pathway undergoing coordinated rounds of fasciculation and defasciculation, which are critical to establishing proper eye-brain connections. How this coordination is achieved is poorly understood, but shedding of guidance cues by metalloproteinases is emerging as a relevant mechanism. Secreted Frizzled Related Proteins (Sfrps) are multif...

Objective(s): Hydatidosis is a zoonotic infection and endemic in Iran. Due to the serological cross-reactivity (of sera) with other parasitic infection, diagnosis of hydatid cyst is considered to be problematic. In this regard, application of recombinant antigens improves serological diagnosis for human hydatidosis. Here, we present an ELISA test based on B8/2 recombinant antigen of Echinococcu...

Objective(s) Recombinant adenoviruses are currently used for a variety of purposes, including in vitro gene transfer, in vivo vaccination, and gene therapy. Ability to infect many cell types, high efficiency in gene transfer, entering both dividing and non dividing cells, and growing to high titers make this virus a good choice for using in various experiments. In the present experiment, a reco...

background: cryptosporidium parvum is a parasitic protozoan that functions as important causa­tive agent of diarrhea in human and animals. the host's immune response to surface anti­gens of c. parvum has been previously demonstrated. in this respect, the role of humoral immu­nity in the development of host protective immunity against this protozoon has been well demon­strated. methods: the effe...

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...

A significant epidemiological association between obesity and pancreatic ductal adenocarcinoma (PDAC) has previously been described, as well as a correlation between the degree of pancreatic steatosis, PDAC risk and prognosis. The underlying mechanisms are still not completely known.After co-culture of 3T3-L1 adipocytes and MiaPaCa2 with an in vitro transwell system we observed the appearance o...
