Abstract:
The role of VEGF during development and in pathology is well known, but its function in normal adult tissues is poorly understood. Adverse effects associated with the use of anti-angiogenic therapies targeting VEGF in human pathologies have begun to reveal potential functions of VEGF in quiescent vasculature. Further clues from expression studies of VEGF and its receptors in the adult, from the disease preeclampsia, and from experimental neutralization studies, have suggested that VEGF is involved in endothelial cell survival and fenestration, as well as in the signaling and maintenance of non-endothelial cells. The various biochemical properties of VEGF, and its interaction with other growth factors, may be an important point in determining whether VEGF functions as a maintenance factor versus an angiogenic factor. A thorough understanding of the function of VEGF in the adult may lead to more efficacious pro- and anti-angiogenic therapies.
Insights
Vascular Endothelial Growth Factor (VEGF) plays a crucial role in maintaining adult tissues, not just during development or disease. Understanding its function in quiescent vasculature is key to improving therapies.
Area of Science:
- Molecular Biology
- Cell Biology
- Physiology
Background:
- Vascular Endothelial Growth Factor (VEGF) is well-characterized in development and pathology.
- Its function in normal adult tissues, particularly quiescent vasculature, remains poorly understood.
- Adverse effects of anti-VEGF therapies hint at its role in healthy adult tissues.
Purpose of the Study:
- To elucidate the function of VEGF in normal adult tissues.
- To investigate VEGF's role in maintaining quiescent vasculature.
- To differentiate VEGF's function as a maintenance versus angiogenic factor.
Main Methods:
- Analysis of VEGF and its receptor expression in adult tissues.
- Review of studies on the disease preeclampsia.
- Experimental VEGF neutralization studies.
Main Results:
- VEGF appears involved in endothelial cell survival and fenestration.
- VEGF signaling and maintenance of non-endothelial cells are suggested.
- Biochemical properties and interactions with other growth factors influence VEGF function.
Conclusions:
- VEGF has a significant role in maintaining normal adult tissues.
- Further understanding of adult VEGF function can optimize pro- and anti-angiogenic therapies.
- Targeting VEGF requires careful consideration of its dual roles.
