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.

More Info

Introduction
GH is a member of the somatotropin/prolactin family of hormones which play an important role in growth control. The gene, along with four other related genes, is located at the gGH locus on chromosome 17 where they are interspersed in the same transcriptional orientation; an arrangement which is thought to have evolved by a series of gene duplications. The five genes share a remarkably high degree of sequence identity. Alternative splicing generates additional isoforms of each of the five GHs, leading to further diversity and potential for specialization. This particular family member is expressed in the pituitary but not in placental tissue as is the case for the other four genes in the GH locus. Mutations in or deletions of the gene lead to GH deficiency and short stature.

Description

FGF2 Thermostable is a stabilized form of FGF2 growth factor which enables a novel method to produce FGF2-dependent cell cultures more efficiently, having less media changes. FGF2 Thermostable can maintain its biological activity even after five days at 37°C. The increase in the stability of FGF2 in cell-culture enables a more homogenous, undifferentiated stem cell culture, while saving scientists crucial time and money, as frequent supplementation of FGF-basic and the everyday medium change is not necessary. Thermostable FGF-2 is a hyperstable protein. The Thermal stability of the protein is increased by 15°C compared to the wild-type FGF-2. Thermostable FGF-2 is more than 5-times prolonged half-life in human cell culture incubated at 37°C. The FGF-2 Thermostable protein is engineered with fully retained biological function and has no harmful stabilizing additives.Thermostable FGF2 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 154 amino acids and having a total calculated molecular mass is 17.2kDa.

More Info

Introduction
Receptor activity modifying protein 3 (RAMP3) belongs to the RAMP family of single-transmembrane-domain proteins, named receptor (calcitonin) activity modifying proteins (RAMPs). RAMP3 is needed to transport calcitonin-receptor-like receptor (CRLR) to the plasma membrane. CRLR acts as either a calcitonin gene-related peptide (CGRP) receptor or an adrenomedullin receptor, depending on which members of the RAMP family are expressed. The existence of RAMP3 effects CRLR to function as an adrenomedullin receptor.

More Info

Introduction
Recombinant Human Sonic Hedgehog is part of a small group of secreted proteins that are vital for development in both vertebrates and invertebrates. 3 mammalian hedgehog genes (sonic, desert, Indian) share about 60% homology. The Human Sonic Hedgehog is 99% homologous to the mouse gene. Sonic HedgeHog is a protein that is vital in guding the early embryo. It has been associated as the major inductive signal in patterning of the ventral neural tube, the anterior-posterior limb axis, and the ventral somites. Sonic HedgeHog binds to the patched receptor, which functions in association with smoothened, to activate the transcription of target genes. In the absence of sonic HedgeHog, patched receptor represses the constitutive signaling activity of smoothened. Sonic HedgeHog also regulates another factor, the gli oncogene. Sonic HedgeHog intercellular signal is essential for a various patterning events during development: signal produced by the notochord that induces ventral cell fate in the neural tube and somites, and the polarizing signal for patterning of the anterior-posterior axis of the developing limb bud. Sonic HedgeHog exhibits both floor plate- and motor neuron-inducing activity. Mutations in a long-range Sonic HedgeHog enhancer located in an intron of the limb region 1 gene result in preaxial polydactyly.

Introduction
Tumor necrosis factor is a cytokine involved in systemic inflammation and is a member of a group of cytokines that all stimulate the acute phase reaction. TNF is mainly secreted by macrophages.
TNF causes apoptotic cell death, cellular proliferation, differentiation, inflammation, tumorigenesis and viral replication, TNF is also involved in lipid metabolism, and coagulation. TNF's primary role is in the regulation of immune cells.
Dysregulation and, in particular, overproduction of TNF have been implicated in a variety of human diseases- autoimmune diseases, insulin resistance, and cancer.
Synonyms
TNF-alpha, Tumor necrosis factor ligand superfamily member 2, TNF-a, Cachectin, DIF, TNFA, TNFSF2.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized Tumor Necrosis Factor-a although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TNF-a should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Solubility
It is recommended to reconstitute the lyophilized Tumor Necrosis Factor-alpha in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Background
Tumor Necrosis Factor-alpha (TNF-α) is a pro-inflammatory cytokine that plays a critical role in the regulation of immune responses, inflammation, and cell survival. It is primarily produced by activated macrophages, but can also be secreted by other immune cells, such as T cells, natural killer cells, and mast cells. TNF-α is involved in a wide range of physiological and pathological processes, including the defense against infections, the development of autoimmune diseases, and the progression of cancer.
TNF-α exerts its effects by binding to two distinct cell surface receptors, TNF receptor 1 (TNFR1) and TNF receptor 2 (TNFR2). Upon binding to its receptors, TNF-α activates multiple signaling pathways, including the nuclear factor-kappa B (NF-κB) pathway, the mitogen-activated protein kinase (MAPK) pathway, and the apoptotic pathway. These signaling pathways regulate various cellular processes, such as inflammation, cell proliferation, differentiation, and apoptosis.
In the context of infections, TNF-α plays a crucial role in the body's defense against pathogens. It promotes the recruitment and activation of immune cells, enhances the production of other pro-inflammatory cytokines, and stimulates the expression of adhesion molecules on endothelial cells, facilitating the migration of immune cells to the site of infection. TNF-α also helps to induce fever, which is an important component of the body's immune response to infections.
However, excessive or prolonged production of TNF-α can contribute to the development of chronic inflammatory diseases, such as rheumatoid arthritis, inflammatory bowel disease, and psoriasis. In these conditions, elevated levels of TNF-α promote the infiltration of immune cells into the affected tissues, leading to tissue damage and the perpetuation of inflammation. The central role of TNF-α in the pathogenesis of these diseases has led to the development of anti-TNF-α therapies, which have revolutionized the treatment of chronic inflammatory diseases. These therapies include monoclonal antibodies, such as infliximab and adalimumab, and soluble TNF receptor fusion proteins, such as etanercept. Anti-TNF-α therapies have been shown to be effective in reducing inflammation, improving symptoms, and slowing disease progression in patients with chronic inflammatory diseases.
In the context of cancer, TNF-α has complex and context-dependent effects on tumor development and progression. On one hand, TNF-α can promote anti-tumor immunity by activating immune cells and stimulating the production of other pro-inflammatory cytokines. On the other hand, chronic inflammation driven by TNF-α can promote tumor growth, angiogenesis, and metastasis. Therefore, the role of TNF-α in cancer is still an area of active research, and the development of TNF-α-targeted therapies for cancer remains a challenge.
In conclusion, TNF-α is a pro-inflammatory cytokine that plays a critical role in the regulation of immune responses, inflammation, and cell survival. Its involvement in various physiological and pathological processes has made it an important target for the development of therapies for chronic inflammatory diseases and cancer. Anti-TNF-α therapies have revolutionized the treatment of chronic inflammatory diseases, but the complex role of TNF-α in cancer remains an area of ongoing research. Understanding the precise mechanisms by which TNF-α contributes to disease pathogenesis will be crucial for the development of more effective and targeted therapies.

More Info

Introduction
Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) was first characterized as a growth factor that supports the in-vitro colony formation of granulocytes-macrophages progenitor cells. It is a pleiotropic cytokine and a member of a family of endogenous cytokines of the hematopoietic system. GM-CSF is produced as a response to immune or inflammatory stimuli by activated cells of the hematopoietic system such as T cells, B cells, macrophages, mast cells and also fibroblasts and alveolar epithelial cells. It plays an important role in regulating the proliferation, differentiation, survival and activation of hematopoietic cells such as granulocytes and monocytes ,neutrophiles, basophiles and eosonophoiles, erythroid cells, megakaryocytes and T cells.
Human and mouse GM-CSF have about 56% homology and are species specific. Human GM-CSF is not active on mouse cells and vice versa. It is active on canine and feline cells.
GMCSF is 144 amino acids, 22kDa glycoprotein. It is composed of four bundles alpha helices. Its receptor is heterodimers with a ligand-specific alpha subunit and a betac subunit that is shared with the interleukin IL-3 and IL-5 receptors. This unusual form of receptor assembly likely applies also to IL-3 and IL-5 receptors. Cross-linking the two receptor subunits is required for receptor activation and signaling .
GMCSF has been shown to be involved in maturation, mobilization and antigen presentation of myeloid dentritic cells (DCs) in-vivo or ex-vivo. This function promotes Th1 immune responses, cytotoxcity, anti-angiogenesis as well as allergic inflammation, and the development of autoimmunity. Therefore GMCSF can be used in immunotherapy for the treatment of immune suppressed and immune-compromised patients as well as in veterinary medicine for the same purpose. GM-CSF is also important in regulation of embryo development and pregnancy and specifically in embryo implantation and subsequent development .
