    • Introduction

      WIF1 binds to wnt proteins and inhibits their activities. WIF1 plays a role in mesoderm segmentation. WNT proteins are extracellular signaling molecules that take part in the control of embryonic development & cancer. WIF1 protein contains a WNT inhibitory factor (WIF) domain and 5 epidermal growth factor (EGF)-like domains. WIF1 takes part in mesoderm segmentation. WIF1 protein is found to be present in fish, amphibia and mammals. WIF1 is a recurrent target in human salivary gland oncogenesis. Downregulation of WIF1 takes part in the development and progression of pleomorphic adenomas. WIF1 is a tumor suppressor, specifically in nonfunctioning pituitary tumors.

    • Synonyms

      Wnt inhibitory factor 1, WIF-1, Wif1.

    • Physical Appearance

      Sterile filtered colorless solution.

    • Stability

    More Info

    • Introduction

      The gene for TNFRSF12A was initially recognized as a fibroblast growth factor inducible immediate early response gene Fn14 in mouse NIH 3T3 fibroblasts. Human TNFRSF12A cDNA encodes a 129 amino acid residue type I transmembrane protein with a 27 aa signal peptide, a 53 aa extracellular domain, a 21 aa transmembrane domain and a 28 aa cytoplasmic domain. Human and mouse TNFRSF12A hold 82% aa sequence identity. TNFRSF12 is the tiniest member of the TNF receptor superfamily and has only one cysteine rich region in its extracellular domain. The TNFRSF12A cytoplasmic domain holds one TRAF binding motif which binds TRAFs 1, 2, and 3. TNFRSF12A binds its ligand TWEAK/TNFSF12A with high affinity to initiate a signal transduction cascade which subject to the cell type, causes different cellular responses such as cell death, cell proliferation, and angiogenesis.

    • Synonyms

      Tumor necrosis factor receptor superfamily member 12A, FN14, CD266 antigen, TweakR, tweak-receptor, Fibroblast growth factor-inducible immediate-early response protein 14, FGF-inducible 14, type I transmembrane protein Fn14.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized TNFRSF12A although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TNFRSF12A 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 TNFRSF12A in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

    • 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, INS resistance, and cancer.

      TNF alpha human, also known as Tumor Necrosis Factor-alpha, is a critical cytokine in the immune system. Macrophages mainly produce this protein, and it plays a key role in inflammation and the acute phase reaction.

      This protein is involved in various cellular functions, including cell death, differentiation, proliferation, and immune regulation.

      Production and Properties

      Tumor Necrosis Factor-alpha is produced recombinantly in E. coli and consists of a single, non-glycosylated polypeptide chain. It includes 157 amino acids of the mature human TNF-alpha and an N-terminal methionine, resulting in a molecular mass of approximately 17.5 kDa.

      Furthermore, the protein is purified through standard chromatographic techniques to ensure high purity and biological activity.

      Solubility and Usage

      The lyophilized form of TNF appears as a sterile, white powder. It is recommended to reconstitute this powder in sterile water to achieve a solution of no less than 100µg/ml.

      This solution can then be further diluted for various experimental applications. TNF alpha is used extensively in research, particularly for studying its effects on cell signaling and immune response.

      Storage and Stability

      For long-term storage, TNF should be kept desiccated below -18°C. Once reconstituted, it should be used within a week if stored at 4°C or kept below -18°C for future use. Avoiding freeze-thaw cycles is crucial to maintain the protein's functionality.

      Biological Role and Implications

      TNF alpha human is involved in the regulation of immune cells and is known for its role in inflammatory processes.

      Dysregulation of TNF alpha production is linked to various diseases, such as autoimmune disorders, insulin resistance, and cancer. It is also a target for therapeutic interventions, particularly in conditions like rheumatoid arthritis and inflammatory bowel disease.

      Mechanism of Action

      TNF alpha can induce fever, apoptotic cell death, and can inhibit tumorigenesis and viral replication. Moreover, it is a potent mediator of the acute phase reaction, which influences the activity of various cells involved in systemic inflammation.

      Research and Clinical Importance

      Scientific research on TNF has provided insights into its complex role in disease mechanisms. Its interaction with receptors such as TNFRSF1A underscores its multifaceted effects across different organ systems, from liver function to brain activity.

      Ongoing studies continue to explore its therapeutic potential, especially how it can be modulated to treat diseases without harmful side effects.

      In essence, TNF alpha human is a versatile and powerful component of the immune system, important for both health and disease. Understanding its pathways and functions helps scientists develop better treatments for various inflammatory and autoimmune diseases.

    • Introduction

      Connective Tissue Growth Factor belongs to the CCN family of proteins. The CCN family presently consists of six members in human also known as: Cyr61 (Cystein rich 61), CTGF (Connective Tissue Growth Factor), Nov (Nephroblastoma Overexpressed gene), WISP-1, 2 and 3 (Wnt-1 Induced Secreted Proteins). The CCN genes encode secreted proteins associated with the Extracellular Matrix (ECM) and cell membrane.
      CCN proteins are matricellular proteins which are involved in the regulation of various cellular functions including: proliferation, differentiation, survival, adhesion and migration. They are expressed in derivatives of the three embryonic sheets and are implicated in the development of kidney, nervous system, muscle, bone marrow, cartilage and bone. During adulthood, they are implicated in wound healing, bone fracture repair, and pathologies such as: fibrosis, vascular ailments and tumorigenesis.
      Full length secreted CCN proteins can show an antiproliferative activity, whereas truncated isoforms are likely to stimulate proliferation and behave as oncogenes.
      The full length protein consists of four modules: Module I shares partial identity with the N-terminal part of the Insulin-like Growth Factor Binding Proteins (IGFBPs).
      Module II includes a stretch of 70amino acid residues – which shares sequence identity with the Von Willebrand Factor Type C repeat (VWC).
      Module III contains sequences sharing identity with the Thrombospondin type 1 repeat (TSP1) (WSXCSXXCG), which is thought to be implicated in the binding of sulfated glycoconjugates and to be important for cell adhesion.
      Module IV, also designated CT, is encoded by exon5. It is the leasts conserved one of the four domains at the level of nucleotide sequence, but it appears to be critical for several of the biological functions attributed to the CCN proteins. Module IV resembles the CT domain of several extracellular protein including, Von Willebrand's factor and mucins. Sequence similarities to heparin-binding motifs are also found within this domain.
      Proteolysis of the secreted full-length CCN proteins that has been reported in the case of CCN2 and CCN3 might result in the production of CCN-derived peptides with high affinity for ligands that full-length CNN proteins bind only poorly. Amino-truncated CCN2 isoforms were biologically active whereas no specific biological activity has been attributed to the truncated CCN3. Although the molecular processes underlying the production of these secreted isoforms is presently unknown, it is important to note that proteolysis occur at the same amino acid residues in both CCN2 and CCN3. An elevated expression of CCN2 has also been detected by Northern blotting in human invasive mammary ductal carcinomas, dermatofibromas, pyogenic granuloma, endothelial cells of angiolipomas and angioleiomyomas, and in pancreatic tumors. A study performed with chondrosarcomas representative of various histological grades established that CCN2 expression was closely correlated with increasing levels of malignancy.
      In agreement with CCN2 playing a role in brain tumor angiogenesis, immunocytochemistry studies indicated that both glioblastoma tumor cells and proliferating endothelial cells stained positive for CCN2. In astrocytomas, CCN2 expression was particularly elevated in high grade tumors, with a marked effect of CCN2 on cell proliferation. Downregulation of CCN2 expression in these cells was associated with a growth arrest at the G1/S transition while over-expression of CCN2 induced a two-fold increase of the number of cells in the G1 phase. Gene profiling analysis allowed to identify a set of about 50 genes whose expression might account for the proliferative activity of CCN2 in these cells.
      CCN2 was seen in a higher proportion of mononuclear cells of patients with acute lymphoblastic leukemia.

      Macrophage-Colony Stimulating Factor Mouse Recombinant: An In-Depth Analysis

      Abstract:

      Macrophage-Colony Stimulating Factor (M-CSF) is a crucial cytokine involved in the regulation of macrophage biology, including their differentiation, survival, and function. This research paper provides an in-depth analysis of M-CSF Mouse Recombinant, focusing on its structure, signaling pathways, and diverse functions in the context of human research. Additionally, the paper explores the therapeutic potential of M-CSF modulation in various diseases.

      Introduction:

      M-CSF plays a vital role in the development and maintenance of macrophages, key immune cells involved in innate immunity and tissue homeostasis. This paper aims to provide a comprehensive analysis of M-CSF Mouse Recombinant, highlighting its importance in human macrophage biology and its potential therapeutic applications.

      Structure and Function of M-CSF:

      M-CSF is a homodimeric protein that binds to its receptor, CSF-1R, leading to the activation of downstream signaling pathways. It regulates the proliferation, survival, and activation of macrophages, influencing immune responses and tissue remodeling processes.

      Signaling Pathways:

      Upon binding to CSF-1R, M-CSF triggers various intracellular signaling pathways, including the MAPK pathway, PI3K/Akt pathway, and JAK/STAT pathway. These pathways regulate gene expression and mediate cellular responses, impacting macrophage functions.

      Role in Macrophage Development and Function:

      M-CSF is essential for the differentiation and maturation of macrophages from hematopoietic progenitor cells. It promotes the survival, proliferation, and activation of macrophages, enhancing their phagocytic activity, cytokine production, and antigen presentation capabilities.

      Therapeutic Potential:

      Given its crucial role in macrophage biology, M-CSF modulation has emerged as a potential therapeutic strategy. M-CSF inhibitors and CSF-1R antagonists have shown promise in the treatment of inflammatory and autoimmune diseases, as well as certain cancers. Targeting M-CSF signaling can modulate immune responses and affect disease progression.

      Clinical Applications and Future Directions:

      The therapeutic potential of M-CSF modulation is being explored in various clinical settings. Clinical trials investigating M-CSF inhibitors as monotherapy or combination therapy are underway in diseases such as rheumatoid arthritis and cancer. Future research should focus on understanding the intricate mechanisms of M-CSF signaling, optimizing therapeutic strategies, and developing personalized treatment approaches.

    • Introduction

      GMFB is part of the GMF subfamily of the larger actin-binding protein ADF family. GMFB is phosphorylated after phorbol ester stimulation, and is crucial for the nervous system. GMFB causes brain cell differentiation, stimulates neural regeneration and inhibits tumor cell proliferation. GMFB overexpression in astrocytes results in the increase of BDNF production. GMFB expression is increased by exercise, thus BDNF is important for exercise-induction of BDNF.

    • Introduction

      CNTF is a polypeptide hormone whose actions appear to be restricted to the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations. The protein is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. A mutation in this gene, which results in aberrant splicing, leads to ciliary neurotrophic factor deficiency, but this phenotype is not causally related to neurologic disease. In addition to the predominant monocistronic transcript originating from this locus, the gene is also co-transcribed with the upstream ZFP91 gene. Co-transcription from the two loci results in a transcript that contains a complete coding region for the zinc finger protein but lacks a complete coding region for ciliary neurotrophic factor.
      CNTF is a survival factor for various neuronal cell types. Seems to prevent the degeneration of motor axons after axotomy.

    • Synonyms

      HCNTF, CNTF, Ciliary Neurotrophic Factor.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

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

    • 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 .

    • 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/ 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 are linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy.

    • Introduction

      CDNF is a member of the ARMET family and acts as a trophic factor for neurons. CDNF inhibits the 6-hydroxy (6-OHDA)-induced degeneration of neurons. When CDNF controlled after 6-OHDA-lesioning, it reestablishes the function and inhibits the degeneration of neurons in substantia nigra. CDNF is universally expressed in neuronal and non-neuronal tissues. The highest levels in the brain are found in the optic nerve and corpus callosum.

    • Introduction

      Complement Factor B, also known as CFB, encodes complement factor B which is a component of the alternative pathway of complement activation. Factor B circulates in the blood as a single chain polypeptide. Once the alternative pathway is activated it is cleaved by complement factor D yielding the noncatalytic chain Ba and the catalytic subunit Bb. The active subunit Bb is a serine protease which connects with C3b to form the alternative pathway C3 convertase. Also, Bb is involved in the proliferation of preactivated B lymphocytes, while Ba inhibits their proliferation.

    • Introduction

      GCSF is a cytokine that controls the production, differentiation, and function of granulocytes. The active protein is found extracellularly. Three transcript variants encoding three different isoforms have been found for this gene. Granulocyte/macrophage colony-stimulating factors are cytokines that act in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytes-macrophages. This csf induces granulocytes.

    • Introduction

      CDNF is a member of the ARMET family and acts as a trophic factor for neurons. CDNF inhibits the (6-OHDA)-induced degeneration of neurons. When CDNF controlled after 6-OHDA-lesioning, it reestablishes the function and inhibits the degeneration of neurons in substantia nigra. CDNF is universally expressed in neuronal and non-neuronal tissues. The highest levels in the brain are found in the optic nerve and corpus callosum.

    • Synonyms

      Cerebral neurotrophic factor, arginine-rich, mutated in early stage tumors-like 1, Conserved neurotrophic factor, ARMET-like protein 1, ARMETL1.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

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

    • Background

      Cerebral Neurotrophic Factor Human Recombinant: A Leap Forward in Neurobiology

      The field of neurobiology is replete with wonder, particularly due to the influential role of neurotrophic factors. These essential proteins, responsible for the survival and growth of neurons, have become a focal point in modern research. Among these, the Cerebral Neurotrophic Factor (CNF) stands out, offering novel insights and potential breakthroughs in our understanding of neurological health.

      Enter the world of bioengineering, a scientific arena where we have successfully replicated CNF, leading to the birth of Cerebral Neurotrophic Factor Human Recombinant (CNF-HR). This is a massive step towards conquering neurodegenerative disorders such as Alzheimer's and Parkinson's diseases, conditions that have perplexed scientists and clinicians for decades.

      The extraordinary capacity of CNF-HR lies in its dual functionality - it acts as a defender and a promoter. It defends neurons from harmful degenerative processes while promoting their growth and development. Picture a devoted gardener who tirelessly protects his garden from pests and nurtures the growth of each plant. In this context, the brain is the vibrant garden, and the neurons, the delicate plants we must care for.

      Although this scientific breakthrough sparks enthusiasm, it's crucial to remember the challenges that lie ahead. The path to determining the most effective method of delivering CNF-HR to the brain, identifying the optimal dosage, and monitoring potential side effects is a winding one. Nevertheless, with continuous research and relentless scientific curiosity, we are optimistic about overcoming these challenges.

      In conclusion, the development of CNF-HR is a significant milestone in the fascinating journey of neurobiology. Its potential to change the trajectory of treating neurodegenerative diseases and enhancing our understanding of neuronal function is tremendous. While the journey is strewn with complexities, the potential rewards we stand to reap promise a future where neurodegenerative diseases could be effectively managed or even cured.
