Abstract EN
Notch signaling is suggested to promote the development and maintenance of cerebral arteriovenous malformations (AVMs), and an increasing wall shear stress (WSS) contributes to AVM rupture.
Little is known about whether WSS impacts Notch signaling, which is important for understanding the angiogenesis of AVMs.
WSS was measured in arteriovenous fistulas (AVF) surgically created in 96 rats at different time points over a period of 84 days.
The expression of Notch receptors 1 and 4 and their ligands, Delta1 and 4, Jagged1, and Notch downstream gene target Hes1 was quantified in “nidus” vessels.
The interaction events between Notch receptors and their ligands were quantified using proximity ligation assay.
There was a positive correlation between WSS and time (r=0.97; P<0.001).
The expression of Notch receptors and their ligands was upregulated following AVF formation.
There was a positive correlation between time and the number of interactions between Notch receptors and their ligands aftre AVF formation (r=0.62, P<0.05) and a positive correlation between WSS and the number of interactions between Notch receptors and their ligands (r=0.87, P<0.005).
In conclusion, an increasing WSS may contribute to the angiogenesis of AVMs by activation of Notch signaling.
