Epidermal growth factor (EGF) is aprotein that stimulatescell growth anddifferentiation by binding to its receptor,EGFR.Human EGF is 6-kDa[5] and has 53amino acid residues and three intramoleculardisulfide bonds.[6]

EGF was originally described as a secreted peptide found in thesubmaxillary glands ofmice and in humanurine. EGF has since been found in many human tissues, includingplatelets,[7]submandibular gland (submaxillary gland),[8] andparotid gland.[8] Initially, human EGF was known asurogastrone.[9]

Structure

[edit]

This sectionis missing information about the entire 1207-aa long gene product: the pro-pre-EGF; what happens if things go wrong (renal hypomagnesemia 4, OMIM 611718). Please expand the section to include this information. Further details may exist on thetalk page.(December 2023)

Inhumans, EGF has 53amino acids (sequence NSDSECPLSHDGYCLHDGVCMYIEALDKYACNCVVGYIGERCzYRDLKWWELR),[6] with amolecular mass of around 6kDa.[5] It contains threedisulfide bridges (Cys6-Cys20, Cys14-Cys31, Cys33-Cys42).[6]

Function

[edit]

EGF, via binding toits cognate receptor, results in cellular proliferation, differentiation, and survival.[10]

Salivary EGF, which seems to be regulated by dietary inorganiciodine, also plays an important physiological role in the maintenance of oro-esophageal and gastric tissue integrity. The biological effects of salivary EGF include healing of oral and gastroesophageal ulcers, inhibition of gastric acid secretion, stimulation of DNA synthesis as well as mucosal protection from intraluminal injurious factors such as gastric acid, bile acids, pepsin, and trypsin and to physical, chemical and bacterial agents.[8]

Biological sources

[edit]

The Epidermal growth factor can be found inplatelets,[7]urine,saliva,milk,tears, andblood plasma.[11] It can also be found in thesubmandibular glands,[8][12] and theparotid gland.[8][12] The production of EGF has been found to be stimulated bytestosterone.[citation needed]

Mechanism

[edit]
Diagram showing key components of theMAPK/ERK pathway. In the diagram, "P" representsphosphate. Note EGF at the very top.

EGF acts by binding with highaffinity toepidermal growth factor receptor (EGFR) on thecell surface. This stimulates ligand-induced dimerization,[14] activating the intrinsic protein-tyrosine kinase activity of the receptor (see the second diagram). Thetyrosine kinase activity, in turn, initiates asignal transduction cascade that results in a variety ofbiochemical changes within the cell – a rise in intracellularcalcium levels, increasedglycolysis andprotein synthesis, and increases in theexpression of certaingenes including the gene for EGFR – that ultimately lead toDNA synthesis and cell proliferation.[15]

EGF-family / EGF-like domain

[edit]
Main article:EGF-like domain

EGF is the founding member of theEGF-family of proteins. Members of this protein family have highly similar structural and functional characteristics. Besides EGF itself other family members include:[16]

All family members contain one or more repeats of theconserved amino acid sequence:

CX7CX4-5CX10-13CXCX8GXRC

WhereC iscysteine,G isglycine,R isarginine, andX represents anyamino acid.[16]

This sequence contains six cysteine residues that form three intramoleculardisulfide bonds. Disulfide bond formation generates three structural loops that are essential for high-affinity binding between members of the EGF-family and theircell-surface receptors.[5]

Interactions

[edit]

Epidermal growth factor has been shown tointeract withepidermal growth factor receptors.[17][18]

Medical uses

[edit]

Recombinant human epidermal growth factor, sold under the brand nameHeberprot-P, is used to treatdiabetic foot ulcers. It can be given by injection into the wound site,[19] or may be used topically.[20] Tentative evidence shows improved wound healing.[21] Safety has been poorly studied.[21]

EGF is used to modify synthetic scaffolds for manufacturing ofbioengineered grafts by emulsionelectrospinning or surface modification methods.[22][23]

Bone regeneration

[edit]

EGF plays an enhancer role on the osteogenic differentiation ofdental pulp stem cells (DPSCs) because it is capable of increasing extracellular matrix mineralization. A low concentration of EGF (10 ng/ml) is sufficient to induce morphological and phenotypic changes. These data suggests that DPSCs in combination with EGF could be an effective stem cell-based therapy tobone tissue engineering applications inperiodontics andoral implantology.[24]

History

[edit]

EGF was the secondgrowth factor to be identified.[25] Initially, human EGF was known asurogastrone.[9]Stanley Cohen discovered EGF while working withRita Levi-Montalcini at theWashington University in St. Louis during experiments researchingnerve growth factor. For these discoveries Levi-Montalcini and Cohen were awarded the 1986Nobel Prize in Physiology or Medicine.
