Summary
A disintegrin and metalloproteinase with thrombospondin type 1 motifs, member 13 (ADAMTS13) plays a role in blood clotting and blood vessel formation. This study details methods to assess ADAMTS13's impact on angiogenesis.
Area of Science:
- Biochemistry
- Vascular Biology
- Protease Function
Background:
- ADAMTS13 cleaves ultra-large von Willebrand factor multimers, preventing platelet aggregation at vascular injury sites.
- Beyond hemostasis, ADAMTS13 is implicated in angiogenesis, the formation of new blood vessels.
Purpose of the Study:
- To investigate the role of ADAMTS13 in stimulating or inhibiting new blood vessel formation.
- To describe methods for characterizing the angiogenic properties of ADAMTS13.
Main Methods:
- Utilized in vitro angiogenesis assays.
- Employed organ culture assays to measure new blood vessel formation.
- Characterized the angiogenic properties of the ADAMTS13 metalloprotease.
Main Results:
- The study established methods to assess ADAMTS13's angiogenic potential.
- Demonstrated the utility of these assays for studying soluble proteins.
Conclusions:
- ADAMTS13 possesses angiogenic properties that can be studied using described in vitro and organ culture methods.
- These methodologies can be applied to investigate angiogenesis in other soluble proteins.

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
