Tissue distribution of mRNA for heparin-binding epidermal growth factor.
Heparin-binding epidermal growth factor (HB-EGF) is a recently identified member of the EGF family. Mature HB-EGF is processed from a larger transmembrane precursor which can itself act as a cell-surface receptor for the internalization of diphtheria toxin into eukaryotic cells. However, to date there is no information available on the distribution of HB-EGF in mammalian tissues. We have therefore used reverse-transcription PCR to analyse the expression of HB-EGF mRNA in a wide range of tissues. HB-EGF transcripts were detected in RNA isolated from 15 of the 22 tissues obtained from adult pigs, which is consistent with the ability of diphtheria toxin to affect many body tissues.
