Background
Title: Transforming Growth Factor-Beta 1 Human: An Insight into its Role in Cellular Regulation
Abstract:

Transforming Growth Factor-Beta 1 (TGF-β1) is a multifunctional cytokine that plays a critical role in various cellular processes, including cell growth, differentiation, apoptosis, and immune regulation. This research paper aims to provide a comprehensive overview of the structure, synthesis, signaling pathways, and biological functions of TGF-β1 in human cells. Additionally, this article highlights the relevance of TGF-β1 in various physiological and pathological conditions, including cancer, fibrosis, and immune disorders. Furthermore, potential therapeutic strategies targeting TGF-β1 signaling are also discussed. The information presented in this paper consolidates the current understanding of TGF-β1 and its significance in cellular regulation.
Introduction:

Transforming Growth Factor-Beta 1 (TGF-β1) belongs to a superfamily of growth factors that regulate various cellular processes. It is synthesized as a precursor protein and undergoes proteolytic cleavage to generate the biologically active form. TGF-β1 exerts its effects by binding to specific cell surface receptors, leading to the activation of downstream signaling cascades. These signaling pathways involve Smad-dependent and Smad-independent mechanisms, which ultimately regulate gene expression and cellular responses.
Biological Functions:

TGF-β1 regulates cell proliferation by exerting both stimulatory and inhibitory effects, depending on the cellular context. It plays a crucial role in tissue development, wound healing, and tissue repair by promoting extracellular matrix synthesis and modulating the immune response. TGF-β1 also has immunomodulatory functions, influencing the differentiation and function of immune cells. However, dysregulation of TGF-β1 signaling is associated with various pathologies, including cancer progression, fibrosis, and autoimmune disorders.
Role in Cancer:

TGF-β1 acts as a tumor suppressor in early stages of cancer by inhibiting cell proliferation and inducing apoptosis. However, in advanced stages, it promotes tumor progression by enhancing tumor cell migration, invasion, and angiogenesis. The dual role of TGF-β1 in cancer highlights its complex involvement in tumorigenesis.
Therapeutic Implications:

Given the significant role of TGF-β1 in various diseases, targeting its signaling pathways has emerged as a potential therapeutic strategy. Several approaches, including small molecule inhibitors, antibodies, and gene therapies, are being explored to modulate TGF-β1 activity in a controlled manner. These interventions hold promise in the treatment of cancer, fibrosis, and other TGF-β1-related disorders.
Conclusion:

Transforming Growth Factor-Beta 1 is a versatile cytokine with diverse functions in cellular regulation. Its role in physiological processes and disease pathogenesis underscores its importance as a therapeutic target. Further investigations into the precise mechanisms and downstream effects of TGF-β1 signaling will contribute to the development of novel therapies for various human disorders.

Introduction
Stem cell factor / KIT ligand (SCF) is a cytokine which binds CD117 (c-Kit). SCF is also known as "steel factor" or "c-kit ligand". SCF exists in two forms, cell surface bound SCF and soluble (or free) SCF. Soluble SCF is produced by the cleavage of surface bound SCF by metalloproteases.
SCF is a growth factor important for the survival, proliferation, and differentiation of hematopoietic stem cells and other hematopoietic progenitor cells. One of its roles is to change the BFU-E (burst-forming unit-erythroid) cells, which are the earliest erythrocyte precursors in the erythrocytic series, into the CFU-E (colony-forming unit-erythroid).

Introduction
PDGF-BB is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a motif of eight cysteines. This gene product can exist either as a homodimer (PDGF-BB) or as a heterodimer with the platelet-derived growth factor alpha polypeptide (PDGF-AB), where the dimers are connected by disulfide bonds. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 7, at sites where this gene and that for COL1A1 are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans resulting from unregulated expression of growth factor. Two splice variants have been identified for this gene.

Introduction
Stem cell factor / KIT ligand (SCF) is a cytokine which binds CD117(c-Kit). SCF is also known as "steel factor" or "c-kit ligand". SCF exists in two forms, cell surface bound SCF and soluble (or free) SCF. Soluble SCF is produced by the cleavage of surface bound SCF by metalloproteases.
SCF is a growth factor important for the survival, proliferation, and differentiation of hematopoietic stem cells and other hematopoietic progenitor cells. One of its roles is to change the BFU-E (burst-forming unit-erythroid) cells, which are the earliest erythrocyte precursors in the erythrocytic series, into the CFU-E (colony-forming unit-erythroid).

More Info

Introduction
VEGF-C152S is a point mutant generated by the replacement of the second conserved Cys residue of the recombinant processed VEGF-C by a Ser residue. VEGF-C 152S is analog to the human VEGF-C 156S mutant and only active toward VEGFR-3/FLT-4 but, unlike wild type VEGF-C, is unable to bind to and to activate signaling through VEGFR-2/KDR. VEGF-C152S was inactive in the vascular permeability assay and did not increase migration of the capillary endothelial cells, indicating that these VEGF-like effects of VEGF-C require VEGFR-2 binding. 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 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 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.

More Info

Introduction
TNFSF15 is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This protein is abundantly expressed in endothelial cells, but is not expressed in either B or T cells. The expression of TNFSF15 is inducible by TNF and IL-1 alpha. This cytokine is a ligand for receptor TNFRSF25 and decoy receptor TNFRSF21/DR6. It can activate NF-kappaB and MAP kinases, and acts as an autocrine factor to induce apoptosis in endothelial cells. TNFSF15 is also found to inhibit endothelial cell proliferation, and thus may function as an angiogenesis inhibitor. An additional isoform encoded by an alternatively spliced transcript variant has been reported but the sequence of this transcript has not been determined.

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.
Synonyms
VEGF-A, VPF, glioma-derived endothelial cell mitogen.

More Info

Introduction
Stem cell factor / KIT ligand (SCF) is a cytokine which binds CD117(c-Kit). SCF is also known as "steel factor" or "c-kit ligand". SCF exists in two forms, cell surface bound SCF and soluble (or free) SCF. Soluble SCF is produced by the cleavage of surface bound SCF by metalloproteases. SCF is a growth factor important for the survival, proliferation, and differentiation of hematopoietic stem cells and other hematopoietic progenitor cells. One of its roles is to change the BFU-E (burst-forming unit-erythroid) cells, which are the earliest erythrocyte precursors in the erythrocytic series, into the CFU-E (colony-forming unit-erythroid).

More Info

Introduction
PDGF-BB is a member of the platelet-derived growth factor family. The four members of this family are mitogenic factors for cells of mesenchymal origin and are characterized by a motif of eight cysteines. This gene product can exist either as a homodimer (PDGF-BB) or as a heterodimer with the platelet-derived growth factor alpha polypeptide (PDGF-AB), where the dimers are connected by disulfide bonds. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 7, at sites where this gene and that for COL1A1 are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans resulting from unregulated expression of growth factor. Two splice variants have been identified for this gene.

Introduction
PDGF-AA, PDGF-BB and PDGF-AB, are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. The PDGF is stored in platelet alpha-granules and released upon platelet activation. The PDGF is involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. Two distinct signaling receptors used by PDGF
have been identified and named PDGFR-alpha and PDGFR-beta. PDGFR-alpha is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR-beta interacts with only PDGF-BB and PDGF-AB.

About TGFB3 (207 a.a.) Human:
Transforming growth factor beta-3 (also known as TGF-β3) is a cytokine encoded by the TGFB3 gene that belongs to the transforming growth factor beta superfamily. It plays a significant role in cell differentiation, embryogenesis, and development by regulating molecules involved in cell adhesion and extracellular matrix formation. TGF-β3 is necessary for palate development, as its absence causes clefting. In addition, it controls lung development and wound healing processes by regulating cell adhesion and movement in the respective tissues. Together, TGF-β3 coordinates a variety of cellular processes that are critical for mammalian embryonic development and tissue homeostasis. In this article we will explore the features and applications of TGFB3 Human Recombinant Protein, expanding on its significance in in advanced research pursuits.
Description:
TGFB3 Human Recombinant protein encodes amino acids 644-850 and total molecular mass of 50 kDa (Including GST Tag). As TGFB3 Human derives from Escherichia Coli, it appears as a sterile filtered clear solution and is formulated as 100µl of purified human TGF Beta 3 protein at 100µg/ml. In addition, its protein is formulated in a solution comprising 50mM Tris-Acetate (pH 7.5), 1mM EDTA, and 20% Glycerol. In terms of stability, TGF-beta 3 Human Recombinant is stable at 4°C for up to a week. However, it is preferable to store at -20°C. However, if you are looking to store it for a long term it is preferable to add a carrier protein (0.1% HSA or BSA).
Activation:
While TGF-β plays a crucial role regulating essential cell functions, its activation pathways is still being explored and understood. Some pathways are specific to certain cells or tissues, while others are more widespread. Factors like proteases, integrins, pH, and reactive oxygen species can activate TGF-β. Disruptions in these factors can lead to uncontrolled TGF-β signaling, causing issues like inflammation, autoimmune diseases, and cancer.
Applications and Usage:
TGFB3 (207 a.a.) Human is intended for laboratory research, serving as an important tool in stem cell differentiation as well as T-cell regulation and differentiation. Accordingly, its versatility extends to applications such as ELISA, Western Blotting, and Inhibition Assays, offering different avenues for discovery and research.
Safety Information:
TGFB3 (207 a.a.) Human is intended for use only in laboratory research, in accordance with safety guidelines. It emphasizes adherence to ethical and regulatory norms and is not intended for use as household chemicals, pharmaceuticals, agricultural products, or food additives.
Protein content
Protein quantitation was carried out by two independent methods:1. UV spectroscopy at 280 nm using the absorbency value of 1.718 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 TGF-b 3 as a Reference Standard.

PDGF-AA, PDGF-BB and PDGF-AB, are potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. The PDGF is stored in platelet alpha-granules and released upon platelet activation. The PDGF is involved in a number of biological processes, including hyperplasia, chemotaxis, embryonic neuron development, and respiratory tubule epithelial cell development. Two distinct signaling receptors used by PDGF
have been identified and named PDGFR-alpha and PDGFR-beta. PDGFR-alpha is high-affinity receptor for each of the three PDGF forms. On the other hand, PDGFR-beta interacts with only PDGF-BB and PDGF-AB.
Synonyms
Platelet-derived growth factor subunit A, PDGF subunit A, PDGF-1, Platelet-derived growth factor A chain, Platelet-derived growth factor alpha polypeptide, Pdgfa, Rpa1.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized Platelet-derived Growth Factor AA although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PDGF-AA 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 Platelet-derived Growth Factor-AA in Sterile 4mM HCl to a concentration of 0.1-1.0 mg/ml. Further dilutions should be made in appropriate buffered solutions.
