Impact of Notch3 Activation on Aortic Aneurysm Development in Marfan Syndrome
Figure 3
DAPT treatment, which inhibits Notch activation, prevented elastin fragmentation. (a–d) Verhoeff-van Gieson (VVG) staining of elastic fibers of the ascending aorta from WT and Fbn1mgR/mgR (mgR) mice at PD42 treated with DMSO (vehicle control) or DAPT; WT mice treated with DMSO (a) or DAPT (c); mgR mice treated with DMSO (b) or DAPT (d) at PD42. (e) Elastin breaks per field under 40x magnification in DMSO- or DAPT-treated WT and mgR mice ( aorta/groups). , ǂ, and †, ANOVA with Tukey-Kramer post hoc test.
