Staphylococcal enterotoxin A is well known as a superantigen and able to be used for cancer immunotherapy. In this study, recombinant Staphylococcal enterotoxin A was genetically conjugated to epidermal growth factor to produce a chimeric protein recombinant Staphylococcal enterotoxin A-epidermal growth factor expressed in Escherichia coli. The recombinant Staphylococcal enterotoxin A-epidermal...
This study was carried out to express human epidermal growth factor (hEGF) in Pichia pastoris GS115. For this aim, the hEGF gene was cloned into the pPIC9K expression vector, and then integrated into P. pastoris by electroporation. ELISA-based assay showed that the amount of hEGF secreted into the medium can be affected by the fermentation conditions especially by culture medium, pH and tempera...
Background and purpose: Human epidermal growth factor (hEGF) is a polypeptide of 53 amino acids with various medical application such as wound healing. The purpose of this study was cloning, expression, and purification of recombinant human EGF (rhEGF) and assessment of its mitogenic effect on NIH 3T3 cells. Materials and methods: Subcloninig of hEGF was performed in to pET24a (+). Protein e...
We analyzed the epidermal growth factor receptor gene using a complementary DNA probe of the epidermal growth factor receptor gene in 21 uncultured primary breast carcinomas and found that the gene was amplified in three of these tumors. We further demonstrated by immunohistochemistry using a monoclonal antibody to the epidermal growth factor receptor that the receptor protein product of this g...
The action of epidermal growth factor on the human duodenal mucosa has been studied by estimating the crypt cell production rate in cultured explants, using a stathmokinetic technique with crypt microdissection. The addition of epidermal growth factor (400 ng/ml) to paired explants from five patients caused an almost fivefold increase in the crypt cell production rate, showing that epidermal gr...
Human blood clotting factor IX, and two chimeric molecules of factor IX, in which the first epidermal growth factor-like domain or both epidermal growth factor-like domains have been replaced by that of human factor X, have been expressed in mouse Cl27 cells. The recombinants have been purified using a metal ion-dependent monoclonal antibody specific for residues l-42 of human factor IX. All re...
