Introduction
GDF8 is a member of the bone morphogenetic protein (BMP) family and the TGF-beta superfamily. This group of proteins is characterized by a polybasic proteolytic processing site which is cleaved to produce a mature protein containing seven conserved cysteine residues. The members of this family are regulators of cell growth and differentiation in both embryonic and adult tissues. This gene is thought to encode a secreted protein which negatively regulates skeletal muscle growth.
Synonyms
GDF-8, MSTN, Growth Differentiation Factor 8, MSTN Muscle Hypertrophy.

Introduction
The somatomedins, or insulin-like growth factors (IGFs), comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of growth hormone (GH; MIM 139250). Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as 'somatomedin' (Daughaday et al., 1972). Three main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2; MIM 147470), and somatomedin B (MIM 193190) (Rotwein, 1986; Rosenfeld, 2003).
Synonyms
Somatomedin C, IGF-I, IGFI, IGF1, IGF-IA, Mechano growth factor, MGF, Des(1-3), Des1-3, Des 1-3, Des (1-3), IGF-1 (4-70).
Physical Appearance

Background
PNC-27, a promising anticancer peptide, has gained attention due to its selective cytotoxicity against cancer cells without harming normal cells. This paper aims to elucidate the biochemical characteristics of PNC-27 and explore its potential therapeutic applications in the field of oncology.
PNC-27, a novel anticancer peptide, holds great promise in the treatment of cancer due to its unique mechanism of action and selective cytotoxicity towards cancer cells (Goldberg et al., 2010). This paper seeks to delve into the biochemical attributes of PNC-27 and its therapeutic potential in cancer treatment.
Derived from the p53 tumor-suppressor protein, PNC-27 exhibits a unique binding affinity for the MDM-2 protein found in the membranes of cancer cells. This binding triggers membrane pore formation, leading to cell lysis and death, leaving normal cells unaffected (Goldberg et al., 2010).
Preclinical studies have highlighted the potential of PNC-27 in treating various types of cancers. Its ability to induce cell death in cancer cells without harming normal cells presents a promising direction for cancer therapeutics. For instance, studies have shown PNC-27 to be effective against lung and breast cancers (Hoshino et al., 2011; Sarafraz-Yazdi et al., 2010).
The promising potential of PNC-27 warrants further exploration in clinical trials to evaluate its efficacy and safety in humans. Furthermore, investigation into its synergistic effects with other cancer treatments could provide a more holistic approach to cancer therapeutics. In conclusion, PNC-27 presents an exciting avenue for cancer research, offering a novel and targeted approach to cancer treatment.

More Info

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. The FGF-23 gene was identified by its mutations associated with autosomal dominant hypophosphatemic rickets (ADHR), an inherited phosphate wasting disorder. Abnormally high level expression of FGF-23 was found in oncogenic hypophosphatemic osteomalacia (OHO), a phenotypically similar disease caused by abnormal phosphate metabolism. FGF-23 mutations have also been shown to cause familial tumoral calcinosis with hyperphosphatemia.

Background
Before it was discovered in 2000, there was a hypothesis that a similar type of protein existed that performed many of the functions we see in FGF23. This was originally referred to as phosphatonin. Various effects were described and noted by researchers including inhibition of production and inhibition of secretion of parathyroid hormone. Derived from the bone Fibroblast Growth Factor 23 is a phosphaturic hormone. It increases phosphate excretion when acting on the kidney and also suppresses the biosynthesis of 1,25(OH)2D3.
Mechanism
Despite various research studies into the topic, many of the mechanisms for the regulations of FGF23 production remain a mystery to the scientific community. While we know that mutations in PHEX, ENPP1 and DMP1 result in the increased expression of FGF23, it is unclear why this occurs. This also means that currently, it is not possible to regulate the production of FGF23 either. We also do not know how signals from FGF23 regulate vitamin D metabolism. However, understanding these types of mechanisms could offer information needed to provide better treatment for deranged bone and mineral metabolism.
Interactions
Molecular interactions involving FGF-23, vitamin D and klotho do provide the solution needed to regulate phosphate levels within the body. Furthermore, an interaction between Vitamin D and FGF3 can have an impact on renal phosphate balance. As well as this, when in the presence of klotho, FGF3 does actually increase bioactivity and begins to change systemic phosphate homeostasis.
Function
Based on research it seems that the main function for FGF23 is the regulation of phosphate concentration in plasma. It seems to be secreted from the osteocytes due to elevated levels . When acting upon the kidneys, the hormone reduces the expression of NPT2. This is a sodium-phosphate cotransporter found in the proximal tube.
As such, it appears as though FGF23 is able to reduce the reabsorption, all the while maxing the excretion of phosphate. It has also been suggested that the hormone is able to suppress 1-alpha-hydroxylase. If this is the case, it can limit its potential to activate vitamin D and thus impair the ability for calcium absorption.
Structure
FGF243 is located on the chromosome 12. It is composed of three exons. The crystal structure of FGF23 is completely different from the common conformation typically adopted by paracrine-acting FGFs. Instead, there is a conformation of the HPR region between beta strands 10 and 12. As well as this, there is a cleft between the other HPR-binding region, the beta1-beta12 loop and this one. This comes before a direct interaction between HPR sulfate and FGF23s backbone atoms. Due to this, endocrine function is benefitted and HPR-binding affinity is reduced for the lipangs.
Certain mutations that cause the protein to be completely resistant to proteolytic cleavage does trigger a surge in activity of the protein and the renal phosphate loss typically found in certain human diseases including hypophosphatemic rickets.
Studies have also revealed that FGF23 is overproduced in certain tumors including phosphaturic mesenchymal tumors. Furthermore a reduced level of activity for this protein is believed to lead to higher phosphate levels and familial tumor calcinosis clinical syndrome.

Introduction
HB-EGF is an EGF related growth factor which signals via the EGF receptor, and stimulates the proliferation of SMC (smooth muscle cells), fibroblasts, epithelial cells and keratinocytes. HB-EGF is expressed in various cell types and tissues, including vascular endothelial cells and SMC, macrophages, skeletal muscle, keratinocytes and particular tumor cells. HB-EGF’s ability to explicitly bind heparin and heparin sulfate proteoglycans is dissimilar from other EGF-like molecules, and might be related to the enhanced mitogenic activity, relative to EGF, that HB-EGF exerts on smooth muscle cells.

Introduction
The somatomedins, or insulin-like growth factors (IGFs), comprise a family of peptides that play important roles in mammalian growth and development. IGF1 mediates many of the growth-promoting effects of growth hormone (GH; MIM 139250). Early studies showed that growth hormone did not directly stimulate the incorporation of sulfate into cartilage, but rather acted through a serum factor, termed 'sulfation factor,' which later became known as 'somatomedin' (Daughaday et al., 1972). Three main somatomedins have been characterized: somatomedin C (IGF1), somatomedin A (IGF2; MIM 147470), and somatomedin B (MIM 193190) (Rotwein, 1986; Rosenfeld, 2003).

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.

Background
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.

Introduction
The FGFs are a family of more than 20 small (~17–26 kDa) secreted peptides. The initial characterization of these proteins focused on their ability to stimulate fibroblast proliferation. This mitogenic activity was mediated through FGF receptors (FGFRs) 1, 2, or 3. A fourth closely related tyrosine kinase receptor (FGFR4) was able to bind the FGFs but did not lead to a mitogenic response.
FGFs modulate cellular activity via at least 5 distinct subfamilies of high-affinity FGF receptors (FGFRs): FGFR-1, -2, -3, and -4, all with intrinsic tyrosine kinase activity and, except for FGFR-4, multiple splice isoforms, and FGFR-5, which lacks an intracellular kinase domain. There is growing evidence that FGFRs can be important for regulation of glucose and lipid homeostasis. The overexpression of a dominant negative form of FGFR-1 in ? cells leads to diabetes in mice, which thus implies that proper FGF signaling is required for normal ? cell function and glycemia maintenance. FGFR-2 appears to be a key molecule during pancreatic development. Moreover, FGFR-4 has been implicated in cholesterol metabolism and bile acid synthesis.
FGF-19, has been shown to cause resistance to diet-induced obesity and insulin desensitization and to improve insulin, glucose, and lipid profiles in diabetic rodents. Since these effects, at least in part, are mediated through the observed changes in metabolic rates, FGF-19 can be considered as a regulator of energy expenditure.
FGF-21 is preferentially expressed in liver, but an exact knowledge of FGF-21 bioactivity and its mode of action have been lacking to date. FGF-21 is a potent activator of glucose uptake on adipocytes, protects animals from diet-induced obesity when overexpressed in transgenic mice, and lowers blood glucose and triglyceride levels when therapeutically administered to diabetic rodents.

Glucagon-like peptide-1 (GLP-1) is derived from the transcription product of the proglucagon gene. The major source of GLP-1 in the body is the intestinal L cell that secretes GLP-1 as a guthormone. The biologically active forms of GLP-1 are: GLP-1-(7-37) and GLP-1-(7-36)NH2.
GLP-1 secretion by L cells is dependent on the presence of nutrients in the lumen of the small intestine. The secretagogues (agents that causes or stimulates secretion) of this hormone include major nutrients like carbohydrate, proteinand lipid. Once in the circulation, GLP-1 has a half life of less than 2 minutes, due to rapid degradation by the enzyme dipeptidyl peptidase-4.
GLP-1 possesses several physiological properties that make it a subject of intensive investigation as a potential treatment of diabetes mellitus. The known physiological functions of GLP-1 include: Increases insulin secretion from the pancreas in a glucose-dependent manner, decreases glucagon secretion from the pancreas, increases beta cells mass and insulin gene expression, inhibits acid secretion and gastric emptying in the stomach, decreases food intake by increasing satiety.
Synonyms
GLP1, Glucagon Like Peptide-1, Incretin hormone.

More Info

Introduction
Follicle stimulating hormone (FSH) is a hormone synthesised and secreted by gonadotropes in the anterior pituitary gland. FSH and LH act synergistically in reproduction: In women, in the ovary FSH stimulates the growth of immature Graafian follicles to maturation. As the follicle grows it releases inhibin, which shuts off the FSH production. In men, FSH enhances the production of androgen-binding protein by the Sertoli cells of the testes and is critical for spermatogenesis. In both males and females, FSH stimulates the maturation of germ cells. In females, FSH initiates follicular growth, specifically affecting granulosa cells. With the concomitant rise in inhibin B FSH levels then decline in the late follicular phase. This seems to be critical in selecting only the most advanced follicle to proceed to ovulation. At the end of the luteal phase, there is a slight rise in FSH that seems to be of importance to start the next ovulatory cycle. Like its partner, LH, FSH release at the pituitary gland is controlled by pulses of gonadotropin-releasing hormone (GnRH). Those pulses, in turn, are subject to the estrogen feed-back from the gonads.

Introduction
The FGFs are a family of more than 20 small (~17–26 kDa) secreted peptides. The initial characterization of these proteins focused on their ability to stimulate fibroblast proliferation. This mitogenic activity was mediated through FGF receptors (FGFRs) 1, 2, or 3. A fourth closely related tyrosine kinase receptor (FGFR4) was able to bind the FGFs but did not lead to a mitogenic response.
FGFs modulate cellular activity via at least 5 distinct subfamilies of high-affinity FGF receptors (FGFRs): FGFR-1, -2, -3, and -4, all with intrinsic tyrosine kinase activity and, except for FGFR-4, multiple splice isoforms, and FGFR-5, which lacks an intracellular kinase domain. There is growing evidence that FGFRs can be important for regulation of glucose and lipid homeostasis. The overexpression of a dominant negative form of FGFR-1 in ? cells leads to diabetes in mice, which thus implies that proper FGF signaling is required for normal ? cell function and glycemia maintenance. FGFR-2 appears to be a key molecule during pancreatic development. Moreover, FGFR-4 has been implicated in cholesterol metabolism and bile acid synthesis.
FGF-19, has been shown to cause resistance to diet-induced obesity and INS desensitization and to improve INS, glucose, and lipid profiles in diabetic rodents. Since these effects, at least in part, are mediated through the observed changes in metabolic rates, FGF-19 can be considered as a regulator of energy expenditure.
FGF-21 is preferentially expressed in liver, but an exact knowledge of FGF-21 bioactivity and its mode of action have been lacking to date. FGF-21 is a potent activator of glucose uptake on adipocytes, protects animals from diet-induced obesity when overexpressed in transgenic mice, and lowers blood glucose and triglyceride levels when therapeutically administered to diabetic rodents.

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 hep-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.
