Popular Choices,VEGF-C and VEGF target embryonic blood vessels

VEGF-C peptide, also known as Vascular Endothelial Growth Factor C, is a crucial protein within the platelet-derived growth factor/vascular endothelial growth factor (PDGF/VEGF) family. Its significance extends across various physiological and pathological processes, most notably in regulating the formation of new blood vessels (angiogenesis) and lymphatic vessels (lymphangiogenesis). This in-depth exploration delves into the multifaceted roles of VEGF-C, its molecular characteristics, and its implications in research and potential therapeutic applications.

VEGF-C: Structure and Function

Vascular endothelial growth factor C (VEGF-C) is a secreted protein that acts as a potent angiogenic factor. It is synthesized as a pre-pro-protein, with the mature form typically being a disulfide-linked homodimeric protein. Human VEGF-C cDNA encodes a pre-pro-protein of 416 amino acid residues, and the recombinant human form produced in HEK293 cells is a polypeptide chain containing 126 amino acids. This recombinant human VEGF-C is biologically active and plays a vital role in the growth and survival of endothelial cells.

The primary function of VEGF-C is to act as a ligand for specific receptors on endothelial cells, namely VEGFR-2 (KDR) and VEGFR-3 (Flt-4). Binding to these receptors initiates signaling cascades that promote endothelial cell proliferation, migration, and survival, leading to the formation of new vascular networks. Notably, VEGF-C is a potent angiogenic factor and promotes lymphangiogenesis, indicating its specific role in the development and maintenance of the lymphatic vascular system. Research has shown that VEGF-C induces angiogenesis in chick embryo chorioallantoic membranes and stimulates the proliferation and migration of porcine aortic endothelial cells in vitro.

VEGF-C and Vascular Development

The intricate role of VEGF-C in vascular development is well-documented. Studies have demonstrated that VEGF-C and VEGF target embryonic blood vessels. While both VEGF and VEGF-C contribute to blood vessel formation, VEGF-C exhibits a more selective binding to lymphatic vasculature, highlighting its specialized function in lymphangiogenesis. VEGFC may function in angiogenesis of the venous and lymphatic vascular systems during embryogenesis, and also in the maintenance of differentiated lymphatic vessels. The growth factor active in angiogenesis, and endothelial cell growth, as VEGF-C is, is essential for proper tissue development and repair.

VEGF-C in Disease and Therapy

Beyond normal physiological processes, VEGF-C is increasingly recognized for its involvement in various pathological conditions, particularly in cancer. VEGF-C mediates tumor growth and metastasis by promoting epithelial-mesenchymal transition (EMT) and facilitating crosstalk between cancer cells. Its ability to stimulate the formation of new blood and lymphatic vessels can aid tumor expansion and spread.

The therapeutic potential of targeting the VEGF-C pathway is an active area of research. Anti-VEGF injections, while primarily known for treating retinal and macular diseases, underscore the broader implications of modulating VEGF signaling. Furthermore, the development of specific inhibitors and antibodies, such as those raised against a synthetic peptide corresponding to residues surrounding Thr189 of human VEGF-C, aims to block its pro-angiogenic and pro-lymphangiogenic activities in disease contexts.

Interestingly, there's also research exploring the interaction of VEGF-C peptide with other molecules. For instance, C-peptide inhibited the VEGF-induced generation of intracellular ROS in a dose-dependent manner, suggesting a potential modulatory role. This research into peptide interactions with VEGF signaling pathways may open new avenues for therapeutic intervention.

VEGF-C and Related Factors

VEGF-C is part of a larger family of growth factors. Understanding its relationship with other members like VEGF is crucial. While both contribute to vascularization, their specific roles can differ. The VEGF-C/VEGFRs axis is a key focus in understanding tumor progression and developing targeted therapies. Other related factors include Vascular Endothelial Growth Factor C (VEGF-C), also known as Vascular Endothelial Growth Factor Related Protein (VRP), which is a recently discovered member of the VEGF growth factor family.

Research Applications and Products

The scientific community utilizes various forms of VEGF-C for research purposes. Human Recombinant VEGF-C is widely available and used in studies investigating its biological effects. These products, such as Recombinant Human VEGF-C / Flt4-L Protein, are valuable tools for researchers studying angiogenesis, lymphangiogenesis, and related cellular processes. The availability of VEGF-C human and related products from reputable suppliers facilitates advancements in understanding this vital protein.

In summary, VEGF-C peptide is a critical regulator of vascular development with significant implications in both health and disease. Its role in angiogenesis, lymphangiogenesis, and its involvement in processes like VEGF-C mediates tumor growth and metastasis make it a compelling target for scientific investigation and therapeutic development. Further research into the specific mechanisms of VEGF-C and its interactions with other molecules promises to yield valuable insights
