The functional role of epidermal growth factor (EGF) in epithelium-derived human colonic carcinoma cells was investigated by transfection with plasmid pUCDS3, which contained synthetic human EGF encoding sequences, into two human colonic carcinoma cell types with dissimilar phenotypic properties: th

β¦ Synopsis
The gene for human epidermal growth factor (hEGF) was chemically synthesized and used for expression in transgenic potato. The hEGF coding sequence was modified by PCR to introduce ATG start codon and fused either to the 35S cauliflower mosaic virus promoter or to the patatin class I promoter. The highest hEGF peptide content, 120 pg/mg soluble protein, was found in potato tubers when the chimeric gene was expressed under the control of patatin promoter.

## Abstract ## BACKGROUND It was recently shown that neuropilinβ1 (NRPβ1), which was described originally as a receptor for the semaphorins/collapsins (ligands involved in neuronal guidance), is a coreceptor for vascular endothelial growth factor (VEGF) and increases the affinity of specific isofo
