Veterinary VEGFR Therapeutic Antibody Development
Background of VEGFR
In the tumor microenvironment, excessive activation of VEGFRs can promote tumor cell growth by increasing angiogenesis, providing more nutrients and oxygen, thereby accelerating their proliferation and spread. Inhibiting the activation of this pathway has become a crucial strategy in companion animal cancer treatment. BioVenic has established a platform for developing veterinary VEGFR therapeutic antibodies, providing a comprehensive range of services covering the entire antibody development process to explore its potential in treating companion animal cancers.
Background of VEGFR
| Full Name | Vascular endothelial growth factor receptor |
|---|---|
| Aliases | FLK1, KDR, CD309. |
| Target Profile | VEGFRs are a group of transmembrane receptor tyrosine kinases that regulate angiogenesis, essential for tissue growth and repair. There are three primary types: VEGFR-1, VEGFR-2, and VEGFR-3. Members of the VEGF family stimulate cellular responses by binding to VEGFRs on the cell surface, regulating the formation and repair of blood vessels. |
MoA of VEGFR
Upon activation, VEGFRs stimulate gene expression through the Ras/MEK/ERK signaling pathway, promoting cell proliferation. VEGFRs also activate PLC-γ, which generates PKC, increasing intracellular calcium levels, and then enhancing vascular permeability. Additionally, VEGFRs promote cell migration by renewing focal adhesions and activating proteins related to cell movement through the FAK pathway. HSP27 activation through the p38 signaling pathway promotes actin reorganization, further facilitating cell migration. Another key pathway is the PI3K pathway, which maintains cell survival by catalyzing the transformation of PIP2 to PIP3. PIP3 recruits Akt to the cell membrane, which boosts cell survival by inhibiting pro-apoptotic proteins like caspase 9 and BAD. The combined actions of these signaling pathways are crucial in promoting cell proliferation, migration, survival, and increasing vascular permeability, thus facilitating angiogenesis, and significantly impacting tumor growth and development.

Application in Veterinary Therapeutics
VEGFR is expressed in various companion animal tumors, including canine mast cell tumors, anal sac adenocarcinoma, T-cell lymphoma, nasal carcinoma, cutaneous squamous cell carcinoma, hair follicle tumors, and feline mammary tumors. Targeting and inhibiting VEGFR offers the potential to effectively block tumor angiogenesis, thereby suppressing tumor growth and metastasis.
