    • Introduction

      Basic 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.

    • Introduction

      Leptin is a protein hormone with important effects in regulating body weight, metabolism and reproductive function. The protein is approximately~16 kDa in mass and encoded by the obese (ob)gene. leptin is expressed predominantly by adipocytes, which fits with the idea that body weight is sensed as the total mass of fat in the body. Smaller amounts of leptin are also secreted by cellsin the epithelium of the stomach and in the placenta. Leptin receptors are highly expressed in areas of the hypothalamus known to be important in regulating body weight, as well as in T lymphocytes and vascular endothelial cells.

    • Introduction

      The term ‘PDGF’ refers to a family of disulphide bond-linked dimeric isoforms that act as autocrine and paracrine growth factors and are produced by a variety of cell types other than platelets.
      They act as potent mitogens for almost all mesenchymally-derived cells. Aberrant expression is involved in certain cancers, fibroproliferative disorders and atherosclerosis. The protein also contributes to wound healing and neural regeneration. There are four members of the PDGF family – PDGF A, PDGF B, PDGF C and PDGF D. Two distinct types of PDGF-A exist – a short form that is soluble and a long form that is retained by the extracellular matrix.

    • Introduction

      STAT1 is a member of the Signal Transducers and Activators of Transcriptionfamily of transcription factors. STAT1 is involved in upregulating genes due to a signal by either type Ior type IIinterferons. In response to IFN-?stimulation, STAT1 forms homodimers or heterodimers with STAT3that bind to the GAS (Interferon-Gamma Activated Sequence) promoter element; in response to either IFN-? or IFN-?stimulation, STAT1 forms a heterodimer with STAT2that can bind the ISRE (Interferon Stimulated Response Element) promoter element. In either case, binding of the promoter element leads to an increased expression of ISG (Interferon Stimulated Genes).

    More Info

    • Introduction

      Interleukin-22 (IL-22), also known as IL-10-related T cell-derived inducible factor (IL-TIF) was initially identified as a gene induced by IL-9 in mouse T cells and mast cells. Mouse IL-22 cDNA encodes a 179 amino acid residue protein with a putative 33 amino acids signal peptide that is cleaved to generate a 147 aa mature protein that shares approximately 79% and 22% aa sequence identity with human IL-22 and IL-10, respectively. IL-22 has been shown to activate STAT-1 and STAT-3 in several hepatoma cell lines and upregulate the production of acute phase proteins. IL-22 is produced by normal mouse T cells upon Con A activation. Mouse IL-22 expression is also induced in various organs upon lipopolysaccharide injection, suggesting that IL-22 may be involved in inflammatory responses. The functional IL-22 receptor complex consists of two receptor subunits, IL-22R (previously an orphan receptor named CRF2-9) and IL-10Rβ (previously known as CRF2-4), belonging to the class II cytokine recep

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized pegylated murine IL22 although stable at room temperature for several days, should be stored desiccated below -20°C. Upon reconstitution at 0.1mg/ml pegylated mouse IL22 and up to 2mg/ml, filter and sterilized, the protein can be stored at 4 degrees Celsius for several weeks making it suitable for long term infusion studies using osmotic pumps. At lower concentration addition of a carrier protein (0.1% HSA or BSA) is suggested. Please prevent freeze-thaw cycles.

    • Solubility

      It is recommended to reconstitute the lyophilized pegylated mouse Interleukin -22 in sterile 0.4% NaHCO3 adjusted to pH 8-9 not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

    • 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 HPR 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.

    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.

      What is the molecular weight/Mw of FGF23 HUMAN Protein?
      FGF23 HUMAN Protein has a total Mw of 22.5kDa.

      What is the source or expression system of FGF23 HUMAN Protein?

    More Info

    • Introduction

      The type II transmembrane protein FASLG is a member of the tumor necrosis factor (TNF) superfamily. A fas ligand/receptor interaction has a significant part in the regulation of the immune system and the advancement of cancer. FASLG is expressed on the activated T cell surface as a nondisulfidelinked homotrimer. FASLG binding to Fas/CD95/TNFRSF6 on a nearby cell prompts apoptosis in the Fas expressing cell. FASLG is released from the cell surface by metalloproteinases as a soluble molecule that stays trimeric and is able to bind with Fas, but its capability to activate apoptosis is radically reduced. In addition, FASLG binds to DcR3 - a soluble trap receptor with no signal transduction capabilities. Flawed Fas-mediated apoptosis causes oncogenesis in addition to drug resistance in existing tumors. Constitutive expression of FASLG in a variety of tumors enables their immune evasion. Both mouse and human FASLG are active on mouse and human 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

      Nogginwhich is encoded by the NOG gene, binds and inactivates members of the transforming growth factor-beta (TGF-beta) superfamily signaling proteins, such as bone morphogenetic protein-4 (BMP4). By diffusing through extracellular matrices more efficiently than members of the TGF-beta superfamily, noggin may play and important role in creating morphogenic gradients. Noggin appears to have pleiotropic effect, both early in development as well as in later stages. Noggin was originally isolated from Xenopus based on its ability to restore normal dorsal-ventral body axis in embryos that had been artificially ventralized by UV treatment. The results of the mouse knockout of noggin suggest that it is involved in numerous developmental processes, such as neural tube fusion and joint formation. There are several dominant human NOG mutations in unrelated families with proximal symphalangism (SYM1) and multiple synostoses syndrome (SYNS1). All NOG mutations altered evolutionarily conserved amino acid residues. The amino acid sequence of human noggin is highly homologous to that of Xenopus, rat and mouse.

    • Synonyms

      SYM1, SYNS1, NOG.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized Noggin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Noggin 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 Noggin in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

    More Info

    • Introduction

      Growth Differentiation Factor-7 (GDF-7) belongs to the BMP family of TGF-b superfamily proteins. GDF7 elicits its bioactivity via a heterodimeric receptor complex comprised of a type 1 (BMPR-IB) and a type II (BMPR-II or Activin RII) serine/threonine kinase receptor. GDF7 signaling results in the phosphorylation and activation of Smad proteins. GDF-7 is also involved in tendon and ligament formation and repair. In addition, GDF7 regulates bone formation, mesenchymal stem cell differentiation, neuronal differentiation, and axon guidance.
