VEGFA Knockout Cell Lines

Gene: VEGFA

Official Full Name: vascular endothelial growth factor Aprovided by HGNC

Gene Summary: This gene is a member of the PDGF/VEGF growth factor family. It encodes a heparin-binding protein, which exists as a disulfide-linked homodimer. This growth factor induces proliferation and migration of vascular endothelial cells, and is essential for both physiological and pathological angiogenesis. Disruption of this gene in mice resulted in abnormal embryonic blood vessel formation. This gene is upregulated in many known tumors and its expression is correlated with tumor stage and progression. Elevated levels of this protein are found in patients with POEMS syndrome, also known as Crow-Fukase syndrome. Allelic variants of this gene have been associated with microvascular complications of diabetes 1 (MVCD1) and atherosclerosis. Alternatively spliced transcript variants encoding different isoforms have been described. There is also evidence for alternative translation initiation from upstream non-AUG (CUG) codons resulting in additional isoforms. A recent study showed that a C-terminally extended isoform is produced by use of an alternative in-frame translation termination codon via a stop codon readthrough mechanism, and that this isoform is antiangiogenic. Expression of some isoforms derived from the AUG start codon is regulated by a small upstream open reading frame, which is located within an internal ribosome entry site. The levels of VEGF are increased during infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), thus promoting inflammation by facilitating recruitment of inflammatory cells, and by increasing the level of angiopoietin II (Ang II), one of two products of the SARS-CoV-2 binding target, angiotensin-converting enzyme 2 (ACE2). In turn, Ang II facilitates the elevation of VEGF, thus forming a vicious cycle in the release of inflammatory cytokines. [provided by RefSeq, Jun 2020]

Background

VEGFA Gene Knockout Cell Lines are sophisticated biological tools engineered to abrogate the expression of the vascular endothelial growth factor A (VEGFA), a critical protein involved in angiogenesis, the formation of new blood vessels from pre-existing vessels. These cell lines serve as essential models for studying the intricate mechanisms of vascular biology, tumor growth, and various pathological conditions where angiogenesis plays a pivotal role, such as cancer, diabetic retinopathy, and cardiovascular diseases.

The key function of VEGFA Gene Knockout Cell Lines lies in their ability to facilitate the investigation of VEGFA signaling pathways and the phenotypic consequences of its absence. By utilizing CRISPR/Cas9 technology, the gene knockout process is precisely executed, ensuring a complete disruption of the VEGFA gene. This allows researchers to delve into cellular behaviors, gene interactions, and responses to therapeutic agents in a controlled environment devoid of VEGFA activity. These models enable high-throughput screening of angiogenesis modulators and are invaluable for drug discovery efforts aimed at targeting pathological angiogenesis.

Scientifically, these cell lines have significant applications in both research and clinical settings. They provide a robust framework for elucidating the role of VEGFA in various diseases, thus guiding the development of targeted therapies that inhibit angiogenesis. Moreover, the ability to study VEGFA’s involvement in tumor microenvironments positions these cell lines as crucial assets for cancer research, offering insights into how tumor cells adapt and thrive in low-oxygen conditions.

One of the standout advantages of our VEGFA Gene Knockout Cell Lines is their high specificity and reliability, compared to traditional models that may exhibit residual VEGFA expression. This specificity ensures that experimental results are due to the absence of VEGFA, reducing confounding factors and enabling clearer data interpretation. Furthermore, our cell lines come with extensive characterization data, enhancing transparency and reproducibility in research.

For researchers and clinicians alike, the value of our VEGFA Gene Knockout Cell Lines cannot be overstated. They represent a gateway to unlocking the complex mechanisms of angiogenesis, providing pivotal insights that can lead to groundbreaking therapies and better clinical outcomes. As a leader in the development of genetically modified cell lines, our company leverages cutting-edge technologies and a commitment to quality, ensuring that our products meet the highest standards of scientific excellence. With these knockout cell lines, you empower your research to contribute to innovative solutions in health and disease management.
