Introduction
Epidermal growth factor has a profound effect on the differentiation of specific cells in vivo and is a potent mitogenic factor for a variety of cultured cells of both ectodermal and mesodermal origin. The EGF precursor is believed to exist as a membrane-bound molecule which is proteolytically cleaved to generate the 53-amino acid peptide hormone that stimulates cells to divide. EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture.

Background
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.

More Info

Introduction
VEGF-C, also known as Vascular Endothelial Growth Factor Related Protein (VRP), is a recently discovered VEGF growth factor family member that is most closely related to VEGF-D. Human VEGF-C cDNA encodes a pre-pro-protein of 416 amino acids residues. It is almost identical to the mouse VEGF-C protein. Similar to VEGF-D, VEGF-C has a VEGF homology domain spanning the middle third of the precursor molecule and long N- and C-terminal extensions. In adults, VEGF-C is highly expressed in heart, placenta, ovary and small intestine. Recombinant human VEGF-C, lacking the N- and C-terminal extensions and containing only the middle VEGF homology domain, forms primarily non-covalently linked dimers. This protein is a ligand for both VEGFR-2/KDR and VEGFR-3/FLT-4. Since VEGFR-3 is strongly expressed in lymphatic endothelial cells, it has been postulated that VEGF-C is involved in the regulation of the growth and/or differentiation of lymphatic endothelium. Although recombinant human VEGF-C is also a mitogen for vascular endothelial cells, it is much less potent than VEGF-A.

Introduction
FGF-23 is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities and are involved in a variety of biological processes including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. FGF-23 inhibits renal tubular phosphate transport. This gene was identified by its mutations associated with autosomal dominant hypophosphatemic rickets (ADHR), an inherited phosphate wasting disorder. Abnormally high level expression of FGF23 was found in oncogenic hypophosphatemic osteomalacia (OHO), a phenotypically similar disease caused by abnormal phosphate metabolism. Mutations FGF23 have also been shown to cause familial tumoral calcinosis with hyperphosphatemia.

More Info

Introduction
Leptin is a protein hormone. It is mainly produced in adipose cells that regulate energy homeostasis by restraining hunger. Leptin ties to nuclear receptors in the hypothalamus (arcuate nucleus). Similar to insulin resistance in type II diabetes, in obesity there is a decrease in the sensitivity towards leptin, ending in a failure to identify satiety, even in high levels of energy stores or leptin itself. Full-length cDNA encoding 2 leptin sequences (tLepA and tLepB) and 1 leptin receptor sequence (tLepR) exists in tilapia (Oreochromis niloticus). The full-length cDNA of tLepR is 3423 bp, encoding a protein of 1140 amino acid which contained all functionally important domains conserved among vertebrate leptin receptors. The cDNAs of tLepA and tLepB are 486 bp and 459 bp in length, encoding proteins of 161 aa and 152 aa, respectively. The three-dimensional structures of tLepA and tLepB demonstrates strong conservation of tertiary structure with that of human leptin comprised of 4 helixes.

More Info

Introduction
Endocrine gland-derived vascular endothelial growth factor (EG-VEGF) induces proliferation, migration, and fenestration in capillary endothelial cells derived from endocrine glands. Its expression is induced by hypoxia and is restricted to the steroidogenic glands (ovary, testis, adrenal, and placenta). Its expression is often complementary to the expression of VEGF (MIM 192240), suggesting that these molecules function in a coordinated manner. EG-VEGF potently contracts gastrointestinal (gi) smooth muscle. Induces proliferation, migration and fenestration (the formation of membrane discontinuities) in capillary endothelial cells derived from endocrine glands. Has little or no effect on a variety of other endothelial and non-endothelial cell types.

Introduction
Vascular endothelial growth factoris an important signaling proteininvolved in both vasculogenesisand angiogenesis. As its name implies, VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/macrophagemigration, neurons, cancer cells, kidney epithelial cells ).VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesisand cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.
Physical Appearance

Introduction
Fibroblast Growth Factor-5 (FGF5) belongs to the FGF family of mitogenic peptides. In vitro, rhFGF5 is a mitogen for Balb/3T3 fibroblasts and bovine heart endothelial cells. FGF5 is also a major muscle-derived survival factor for cultured spinal motoneurons. In vivo, FGF5 is assumed to play central roles in both embryology and neurobiology. Developmentally, FGF5 mRNA is originally found in the embryoblast followed by the lateral somatic mesoderm, where it may play a part in angiogenesis, as well as the myotomes cranial to the tail region, where it may delay terminal myoblast differentiation during cell migration.

More Info

Introduction
VEGF-C, also known as Vascular Endothelial Growth Factor Related Protein (VRP), is a recently discovered VEGF growth factor family member that is most closely related to VEGF-D. Human VEGF-C cDNA encodes a pre-pro-protein of 416 amino acids residues. It is almost identical to the mouse VEGF-C protein. Similar to VEGF-D, VEGF-C has a VEGF homology domain spanning the middle third of the precursor molecule and long N- and C-terminal extensions. In adults, VEGF-C is highly expressed in heart, placenta, ovary and small intestine. Recombinant human VEGF-C, lacking the N- and C-terminal extensions and containing only the middle VEGF homology domain, forms primarily non-covalently linked dimers. This protein is a ligand for both VEGFR-2/KDR and VEGFR-3/FLT-4. Since VEGFR-3 is strongly expressed in lymphatic endothelial cells, it has been postulated that VEGF-C is involved in the regulation of the growth and/or differentiation of lymphatic endothelium. Although recombinant human VEGF-C is also a mitogen for vascular endothelial cells, it is much less potent than VEGF-A.
Synonyms
VEGF-C, Vascular endothelial growth factor C, VRP, Flt4 ligand, Flt4-L, Vascular endothelial growth factor-related protein, VEGFC.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized VEGF-C although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution VEGF-C should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.
Solubility
It is recommended to reconstitute the lyophilized VEGF-C in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Introduction
Acidic fibroblast growth factor is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Three alternatively spliced variants encoding different isoforms have been described. The heparin-binding growth factors are angiogenic agents in vivo and are potent mitogens for a variety of cell types in vitro. There are differences in the tissue distribution and concentration of these 2 growth factors.

More Info

Introduction
VEGF-C, also known as Vascular Endothelial Growth Factor Related Protein (VRP), is a recently discovered VEGF growth factor family member that is most closely related to VEGF-D. The rat VEGFC cDNA encodes a pre-pro-protein of 416 amino acids residues.
It is almost identical to the mouse VEGF-C protein. Similar to VEGF-D, VEGF-C has a VEGF homology domain spanning the middle third of the precursor molecule and long N- and C-terminal extensions. In adults, VEGF-C is highly expressed in heart, placenta, ovary and small intestine. Recombinant rat VEGF-C, lacking the N- and C-terminal extensions and containing only the middle VEGF homology domain, forms primarily non-covalently linked dimers. This protein is a ligand for both VEGFR-2/KDR and VEGFR-3/FLT -4. Since VEGFR-3 is strongly expressed in lymphatic endothelial cells, it has been postulated that VEGF-C is involved in the regulation of the growth and/or differentiation of lymphatic endothelium. Although recombinant rat VEGF-C is also a mitogen for vascular endothelial cells, it is much less potent than VEGF-A.
Synonyms
VEGF-C, Vascular endothelial growth factor C, VRP, Flt4 ligand, Flt4-L.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized Vascular Endothelial Growth Factor-C although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution VEGF-C should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.
Solubility
It is recommended to reconstitute the lyophilized Vascular Endothelial Growth Factor C in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Introduction
Vascular endothelial growth factor is an important signaling protein involved in both vasculogenesis and angiogenesis. As its name implies, VEGF activity has been mostly studied on cells of the vascular endothelium, although it does have effects on a number of other cell types (e.g. stimulation monocyte/macrophage migration, neurons, cancer cells, kidney epithelial cells ).VEGF mediates increased vascular permeability, induces angiogenesis, vasculogenesis and endothelial cell growth, promotes cell migration, and inhibits apoptosis. In vitro, VEGF has been shown to stimulate endothelial cell mitogenesis and cell migration. VEGF is also a vasodilator and increases microvascular permeability and was originally referred to as vascular permeability factor.
Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

More Info

Introduction
KGF is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. FGF7 is a potent epithelial cell-specific growth factor, whose mitogenic activity is predominantly exhibited in keratinocytes but not in fibroblasts and endothelial cells. Studies of mouse and rat homologs of this gene implicated roles in morphogenesis of epithelium, reepithelialization of wounds, hair development and early lung organogenesis.

Background
FGF stands for fibroblast growth factor that have proteins encoded inside them. The FGF family possess broad mitogenetic activities and are involved in a lot of processes in the body. Some of the biological processes that they are included in are embryonic development, cell growth, tumor growth and tissue repair. FGF-7 is often also commonly referred to as keratinocyte growth factor or KGF and studies have focused on the link between the protein and certain tumor growth.
Structure
Studies have found that the crystal structure of FGF7 is comparatively similar to that of FGF10. For instance, FGF7 does interact with D2, linker as well as D3 of the receptor. Similar to other FGFs much of interaction to do with D2 is confined to conserved residues as well as the residue Arg 251 in the linker domain and the hydrophobic surface of D2. That said there are notable differences and some models predict that FGF7 actually interacts with three loops in D3.
Mechanism
A member of the FGF family, this factor acts completely exclusively through a subset of FGF receptor isoforms. These are mainly expressed by epithelial cells. Indeed, studies suggest that the factor specifically acts on epithelial cells. This in turn causes increased proliferation differentiation and migrations of the aforementioned cells.
Interactions
FGF7 and FGF10 can interact with one of the FGF receptors that is expressed by the epithelial cells. As such, it could be the case that this interaction could cause a protective factor for these epithelial tissues. The protein has also been shown to interact with Perlecan. Also referred to as basement membrane specific heparan sulfate proteoglycan core protein, this is encoded by the HSPG2 gene. A large multi domain this cross-links and binds to various extracellular matrix components as well as self surface molecules. Since FGF7 binds specifically with the perlecan protein, research suggests that i should be considered a novel biological ligand for FGF-7. This could mean that interaction has an influence on both tissue remodeling and cancer growth.
Function
Studies have shown that FGF-7 expression is completely unregulated during minor or even chronic injury. This has lead researchers to believe that the protein is used to heal or repair epithelial cells. Furthermore, FGF-1 also triggers the formation of apical ectodermal ridge throughout the development of limbs in the body.
Recently, it has seemed to be the case that FGF-7 has been linked to skin injury repair, and has also been found to play some sort of role in breast cancer. As well as this, it is a vital regulator of HPC’s. It is vital because it can induce de novo activation of these HPCs.
Further research has shown that FGF6 is a niche signal that is required for the stimulation of adult liver progenitor cells and this can support liver regeneration. This research has lead to the suggestion that FGF7 could be a possibility therapeutic target for those suffering from liver diseases.
Studies like this are just one of the reasons why researchers continue to explore fgf-7, it’s functions and interactions.
Protein content
Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm using the absorbency value of 0.9 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of KGF as a Reference Standard.
