More Info

Introduction
GDF3 is a member of the TGF-beta superfamily though it does not show similarity pattern of conserved cysteine residues. GDF3 is linked to Vg-1 and human BMP-4. GDF3 transcripts are identified mainly in adult bone marrow, spleen, thymus, and adipose tissue. GDF3 expression is upregulated strongly in high-fat-fed C57Bl/6J FABP4/aP2 null mice, which develop obesity but not the related hyperglycemia or hyperinsulinemia characteristic of type II diabetes. GDF3 expression therefore bonds fatty acid metabolism in adipocytes and the expression of a differentiation regulator belonging to the bone morphogenetic proteins.

Introduction
GDF15 is part of the TGF-Beta superfamily that is involved in regulating inflammatory and apoptotic pathways in injured tissues and throughout disease processes. GDF15 is most abundant in the liver. Its expression in liver can be considerably up-regulated in during injury of organs such as liver, kidney, heart and lung. GDF-15 promotes proliferation or growth arrest and differentiation due to differences in cellular differentiation. GDF15 prevents apoptosis in cerebellar granule neurons by activating Akt and inhibiting endogenously active ERK. GDF15 is a novel autocrine/endocrine factor that antagonizes the hypertrophic response and loss of ventricular performance.

Background
VEGFR-1 (Vascular Endothelial Growth Factor Receptor-1), also known as Flt-1 (Fms-like tyrosine kinase 1), is a critical receptor involved in angiogenesis and vascular development. This research paper delves into the structure, function, and therapeutic implications of VEGFR-1, shedding light on its multifaceted role in various physiological and pathological processes.
VEGFR-1 is a transmembrane receptor tyrosine kinase belonging to the VEGF receptor family. It is primarily expressed on endothelial cells and plays a pivotal role in mediating the cellular responses to VEGF ligands. Upon ligand binding, VEGFR-1 initiates intracellular signaling cascades that regulate endothelial cell proliferation, migration, and survival, ultimately contributing to the formation of new blood vessels.
The structure of VEGFR-1 comprises distinct domains, including an extracellular ligand-binding domain, a transmembrane domain, and an intracellular tyrosine kinase domain. The extracellular domain facilitates the interaction between VEGF ligands and the receptor, while the intracellular domain transduces downstream signals by phosphorylating specific tyrosine residues.
VEGFR-1 exhibits not only ligand-dependent but also ligand-independent functions. In addition to its role as a VEGF receptor, it can act as a decoy receptor, sequestering VEGF and modulating the bioavailability of VEGF ligands. This unique property allows VEGFR-1 to regulate VEGF signaling and influence angiogenic processes.
The signaling pathways activated by VEGFR-1 are diverse and intricate, involving multiple downstream effectors, such as PI3K/AKT, MAPK/ERK, and STAT proteins. These pathways regulate endothelial cell behaviors, including proliferation, migration, and differentiation, which are crucial for angiogenesis. Perturbations in VEGFR-1 signaling have been implicated in various pathological conditions, including cancer, retinopathy, and inflammatory disorders.
The therapeutic targeting of VEGFR-1 has gained considerable attention for its potential in managing angiogenesis-related diseases. Inhibitors specifically designed to block VEGFR-1 have been developed to suppress aberrant angiogenesis and impede tumor growth. Moreover, VEGFR-1-based therapies have been explored for ocular diseases like wet age-related macular degeneration (AMD) and diabetic retinopathy, aiming to alleviate pathological neovascularization.
The availability of VEGFR-1 human recombinant proteins has facilitated in-depth research and the development of potential therapeutic interventions. Recombinant VEGFR-1 proteins serve as valuable tools for investigating VEGF-VEGFR-1 interactions, screening drug candidates, and elucidating the underlying molecular mechanisms of VEGFR-1-mediated signaling pathways.

More Info

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.

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.

More Info

Introduction
NGF-beta has nerve growth stimulating activity and the complex is involved in the regulation of growth and the differentiation of sympathetic and certain sensory neurons. Mutations in this gene have been associated with hereditary sensory and autonomic neuropathy, type 5 (HSAN5), and dysregulation of this gene's expression is associated with allergic rhinitis. Nerve Growth Factor was the 1st protein found from the family of neurotrophic factors that influence the growth and differentiation of sympathetic and sensory neurons. NGF consists of 3 different subunits: alpha, beta, and gamma. The beta subunit is accountable for its growth stimulating activity. The synthesis of NGF in astrocytes is enhanced by a range of cytokines such as IL1, TNF-a, PDGF & TGF-b.

The Trefoil Factor peptides (TFF1, TFF2 and TFF3) are stable secretory proteins expressed in the gastrointestinal tract (gastric mucosa), and are involved in intestinal mucosal defense and repair. TFF1 is an essential protein for normal differentiation of the antral and pyloric gastric mucosa and functions as a gastric-specific tumor suppressor gene. TFF1 is a stabilizer of the mucous gel overlying the gastrointestinal mucosa that provides a physical barrier against various noxious agents. TFF1 protects the mucosa from isults, stabilizes the mucus layer, & affects healing of the epithelium. TFF1 is commonly expressed in tumors. TFF1 is related with the cell membrane of MCF-7 cells. High levels of TFF1 and TFF2 are found in serum from inflammatory bowel disease.

More Info

Introduction
TIMP2 belongs to the TIMP gene family. The proteins encoded by this gene family are natural inhibitors of the matrix metalloproteinases, a group of peptidases that take part in degradation of the extracellular matrix. Besides having an inhibitory role against metalloproteinases, the encoded protein has a exclusive part among TIMP family members in its capability to directly suppress the proliferation of endothelial cells. Consequently, the encoded protein is crucial to the conservation of tissue homeostasis by suppressing the production of quiescent tissues as an answer to angiogenic factors, and by inhibiting protease activity in tissues undergoing renovation of the extracellular matrix.

Background
An Insight into Milk Fat Globule-EGF Factor 8 Protein (Mouse Recombinant): Characteristics, Applications, and Future Directions
Abstract
The Milk Fat Globule-EGF Factor 8 (MFG-E8) protein, particularly in its mouse recombinant form, has emerged as a pivotal player in multiple physiological processes. This paper aims to elucidate its unique characteristics, delve into current methodologies employed in its study, and chart the trajectory for future research directions.
Introduction
Milk Fat Globule-EGF Factor 8 (MFG-E8) is a glycoprotein known for its vital role in several cellular processes, including cell signaling, apoptosis, and phagocytosis. The recombinant form of MFG-E8 derived from mouse models offers a valuable tool for researchers in deciphering its biological relevance.
Characteristics of MFG-E8 (Mouse Recombinant)
1. Structural Profile: The MFG-E8 protein harbors EGF-like domains, which enable its participation in numerous cellular signaling events.
2. Expression Spectrum: While originally identified in mammary epithelial cells, its expression spectrum extends to macrophages, dendritic cells, and other tissues.
3. Biochemical Activity: It plays a key role in facilitating the phagocytic clearance of apoptotic cells by bridging these cells to phagocytes.
Methodologies Employed in MFG-E8 Research
1. Production of Recombinant MFG-E8: Using bacterial expression systems, such as E. coli, mouse MFG-E8 DNA is introduced, followed by protein purification techniques like gel filtration chromatography.
2. Assays: The phagocytosis assays employing fluorescently tagged apoptotic cells and phagocytes enable researchers to quantify MFG-E8's effectiveness in apoptotic cell clearance.
3. Immunoblotting: Through SDS-PAGE and Western blotting, the expression and purification of MFG-E8 can be monitored and validated.
4. Knockout Models: MFG-E8 knockout mice models help decipher its in vivo significance, especially concerning its immune-regulatory roles.
Original Ideas & Implications
The potential for MFG-E8, particularly in its mouse recombinant form, to serve as a therapeutic agent in autoimmune disorders remains a tantalizing prospect. Considering its role in apoptotic cell clearance, dysregulation in MFG-E8 might be implicated in the etiology of autoimmune disorders. Thus, targeting this protein therapeutically may pave the way for innovative treatments.
Conclusions & Future Directions
While the recombinant MFG-E8 protein has elucidated much about the biological implications of this protein, the horizon is rife with potential. Future research might focus on its therapeutic potential, particularly in autoimmunity and inflammation.

Introduction
GMCSF is a cytokine that controls the production, differentiation, and function of granulocytes and macrophages. The active form of the protein is found extracellularly as a homodimer. This gene has been localized to a cluster of related genes at chromosome region 5q31, which is known to be associated with interstitial deletions in the 5q- syndrome and acute myelogenous leukemia. Other genes in the cluster include those encoding interleukins 4, 5, and 13.
GM-CSF stimulates the growth and differentiation of hematopoietic precursor cells from various lineages, including granulocytes, macrophages, eosinophils and erythrocytes. Granulocyte Macrophage Colony Stimulating Factor is a potent species-specific growth factor produced by a variety of cell types including T cells, B cells, macrophages, mast cells and endothelial cells. GM-CSF is produced in response to cytokine or immune stimulation and has been shown to stimulate the proliferation, maturation and function of hematopoietic cells.

More Info

Introduction
TGFBR2 is part of the Ser/Thr protein kinase family and the TGFB receptor subfamily. TGFBR2 is a transmembrane protein that has a protein kinase domain, forms a heterodimeric complex with another receptor protein, and binds TGF-beta. This receptor/ligand complex phosphorylates proteins, which then enter the nucleus and regulate the transcription of a subset of genes related to cell proliferation. Mutations in TGFBR2 gene have been associated with Marfan syndrome, Loeys-Deitz Aortic Aneurysm Syndrome, and the development of various types of tumors. TGFBR2 expression is increased in oral squamous cell carcinoma cells. TGFBR2 attenuates the biological activities of TGF-beta in colorectal cancer. TGFBR2 expression is decreased by IL-1beta while inducing Sp3 via NFkappaB.

Introduction
Epidermal growth factor has a profound effect on the differentiation of specific cells in vivo and is a potent mitogenic factor for a variety of cultured cells of both ectodermal and mesodermal origin. The EGF precursor is believed to exist as a membrane-bound molecule which is proteolytically cleaved to generate the 53-amino acid peptide hormone that stimulates cells to divide. EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. Long EGF is a recombinant analog of Human EGF developed as a replacement for use in therapeutic cell culture applications as a like-for-like supplement for Recombinant Human or native EGF. It includes the Human EGF amino acid sequence plus a 53 amino acid N-terminal extension peptide.

More Info

Introduction
Endothelial cells express three different vascular endothelial growth factor (VEGF) receptors, belonging to the family of receptor tyrosine kinases (RTKs). They are named VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1), VEGFR-3 (Flt-4). Their expression is almost exclusively restricted to endothelial cells, but VEGFR-1 can also be found on monocytes, dendritic cells and on trophoblast cells. The flt-1 gene was first described in 1990. The receptor contains seven immunoglobulin-like extracellular domains, a single transmembrane region and an intracellular splited tyrosine kinase domain. Compared to VEGFR-2 the Flt-1 receptor has a higher affinity for VEGF but a weaker signaling activity. VEGFR-1 thus leads not to proliferation of endothelial cells, but mediates signals for differentiation. Interestingly a naturally occuring soluble variant of VEGFR-1 (sVEGFR-1) was found in HUVE supernatants in 1996, which is generated by alternative splicing of the flt-1 mRNA. The biological functions of sVEGFR-1 still are not clear, but it seems to be an endogenous regulator of angiogenesis, binding VEGF with the same affinity as the full-length receptor.
Synonyms
FLT-1, FLT1, Tyrosine-protein kinase receptor FLT, Flt-1, Tyrosine-protein kinase FRT, Fms-like tyrosine kinase 1, VEGFR-1.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized FLT-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FLT1 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 FLT1 D4 in sterile water not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
