About EGF:

In the sphere of biomedical studies, epidermal boom factor (EGF) is a cornerstone that gives precious insights into the mechanisms underlying tissue healing, differentiation, and mobile proliferation. In this article we will explore the characteristics and uses of epidermal growth factor (EGF).

Description:

Epidermal growth factor (EGF) is a 6-kDa protein consisting of 53 amino acid residues and 3 intramolecular disulfide linkages. Human tissues, such as platelets, the parotid gland, and the submandibular gland, are rich in EGF. EGF, which was first discovered in human urine and the submaxillary glands of mice, functions as a major modulator of cell proliferation by attaching to its receptor, EGFR, which is found on the cell membrane. EGF triggers autophosphorylation of transmembrane protein tyrosine kinase EGFR upon binding, hence initiating downstream signaling cascades through pathways such as phosphatidylinositol and ras. Beyond the cell membrane, EGF has a variety of roles as it also initiates cytoplasmic processes such actin depolymerization and membrane ruffle formation. Studies indicate that EGF and its receptor might possibly be important components of the nucleus, highlighting the complexity of EGF-mediated cellular responses.

Function:

By attaching to the epidermal growth factor receptor (EGFR), EGF promotes the survival, differentiation, and multiplication of cells. This connection is essential for boosting many physiological processes and stimulating cell proliferation. The preservation of oro-esophageal and stomach tissue integrity is greatly supported by salivary EGF, which is regulated by dietary inorganic iodine. Its actions include the healing of gastric and oral ulcers, the inhibition of gastric acid secretion, the stimulation of DNA synthesis, and the protection of mucosal surfaces against harmful substances such as bile acids, gastric acid, and bacteria. Salivary EGF's role extends to repairing gastric tissue and addressing oro-esophagal issues, showcasing its healing ability in resolving oral and gastrointestinal ailments, including ulcers.

Mechanism:

EGF functions by forming a strong bond with the cell surface's epidermal growth factor receptor (EGFR), which triggers ligand- induced dimerization. This incident sets off the intrinsic protein-tyrosine kinase activity of EGFR, which in turn initiates a signal transduction cascade inside the cell. Numerous biochemical changes are brought about by this cascade, such as increased intracellular calcium levels, increased glycolysis and protein synthesis, and increased expression of particular genes, most notably the EGFR gene. These carefully planned alterations eventually promote DNA synthesis and cell division, illuminating the complex process by which EGF directs basic biological functions and modulates cellular responses.

IGF stands for INS like growth factors, which are proteins that have a high similarity to INS. They are part of a complicated process that uses cells to communication with the physiologic environment around them. IGF’s complex system is often called the ‘axis’. This consists of:
● Two cell-surface receptors (IGF1R and IGF2R)
● Two ligands (IGF-1 and IGF-2)
● A family of six high-affinity IGF-binding proteins.
● Proteases.

The Effect IGF Has On The Body
Many unique tissue types express the IGF-1 receptor, and the effects can vary. It induces the survival of neurons, may catalyse skeletal muscle hypertrophy by inducing protein synthesis, and by blocking muscle atrophy. It works as a protector for cartilage cells, and may work to be an anabolic factor for the bones. When used in high concentrations, it can activate the INS receptor, and can even complement the effects that INS has on the body.

Diseases And IGF
Diseases and IGF are closely related, and a number of them can be affected. The INS IGF axis is thought to have an effect on aging, with an increased life span shown in fruit flies when used in studies.
It is also important to note the crucial role that IGF plays in cancer and diabetes - IGF- 1 has been shown to stimulate growth in both prostate and breast cancer cells. The degree of risk that IGF-1 poses is up for debate, and many scientists are not in agreement. IGF has also shown to have the ability to decrease blood glucose levels, although not quite as effective as INS.

How Was IGF Discovered?
Investigators began studying the effects of biological substances on cells and tissues outside the body when IGFs were discovered. The name is self explanatory in the fact that IGF performs INS actions in some tissues, but is less potent than INS at decreasing blood sugar. Its fundamental action is to stimulate growth, whether that be within the epidermal growth factor or the nerve growth factor.

What’s The Difference Between IGF-1 And IGF-2?
The two types of IGF are IGF-1 and IGF-2. Although the names are similar, the specific actions that they take are different - they bind and activate completely difference receptors. The major actor in them both is the effect that they have on cell growth. Most of the actions of the pituitary GH are mediated by IGFs, but predominantly IGF-1. GH works to stimulate many tissues within the body, especially the liver which then secretes IGF-1. This then causes hypertrophy, or in layman's terms, an increase in cell size, as well as hyperplasia which is an increase in the number of cells.
The IGF-1 concentration will increase during childhood and hit peak during puberty, but will then decrease afterwards, as does the hormone secretion itself. It has been proven that children and adults with a deficiency of the GH have low serum IGF-1 concentrations when put in comparison with others in the same age range. Patients who have conditions like acromegaly have been shown to have increased serum IGF-1 concentrations. The production of IGF-2 is less dependent on the secretion of GH than IGF-1, and is much less important for stimulating linear growth.
