Production of recombinant human epidermal growth factor in Pichia pastoris

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...

Growth and development in rats given recombinant human epidermal growth factor(1-48) as neonates.

To assess effects of supraphysiologic doses of human recombinant epidermal growth factor(1-48) (rhEGF(1-48)) on neonatal rats, 10 litters of Wistar rats/treatment group were given 0 (formulated vehicle), 10, 100, or 1000 microg/kg daily by subcutaneous injection on postnatal days (PND) 1 through 6. Clinical signs, body weight, acquisition of developmental landmarks and reflexes, and behavior we...

Human recombinant epidermal growth factor in experimental corneal wound healing.

Human recombinant epidermal growth factor (hEGF) was evaluated in various corneal wound healing models in the rabbit. Human EGF accelerated epithelial wound healing in corneal reepithelialization, anterior-keratectomy, and alkali-burn models at concentrations of 10-500 micrograms/ml given four times daily (qid). In the corneal reepithelialization model, 100 micrograms/ml of hEGF qid produced a ...

Co-expression of recombinant human nerve growth factor with trigger factor chaperone in E. coli

Nerve growth factor (NGF) is a neurotrophic factor that is functional in the survival, maintenance and differentiation of nervous system cells. This protein has three subunits, of which the beta subunit has the main activity. Its structure consists of a cysteine knot motif made up of beta strands linked by disulfide bonds. It can be used as a therapeutic agent in the treatment of many diseases....
