Abstract
Brain senescence is associated with impaired endothelial barrier function, angiogenic and inflammatory activity, and propensity to brain hemorrhage. The same pathological changes occur in cerebral cavernous malformations (CCM), a genetic neurovascular anomaly. We hypothesized common transcriptomic and plasma cytokine signatures in the aging brain and CCM. We identified 320 genes [fold change ≥1.5; p < 0.05; false discovery rate (FDR) corrected] commonly dysregulated in the aging brain and CCM. Ontology and pathway analyses of the common differentially expressed genes were related to inflammation and extracellular matrix organization. Plasma levels of C-reactive protein and angiopoietin-2 were significantly greater in older compared to younger healthy non-CCM subjects and were also greater in CCM (Sporadic and Familial) subjects regardless of age (all: p < 0.05; FDR corrected). Plasma levels of vascular endothelial growth factor were significantly greater in older compared to younger subjects, in both healthy non-CCM and Sporadic-CCM groups (all: padj < 0.05). Plasma levels of vascular endothelial growth factor were also significantly greater in Familial-CCM cases with germ line mutations regardless of age (all: padj < 0.05) compared to both healthy non-CCM and Sporadic-CCM subjects. Brain white matter vascular permeability assessed by MRI followed the same pattern as vascular endothelial growth factor across all groups. In addition, quantitative susceptibility mapping of brain white matter, a measure of iron deposition, was increased in older compared to younger healthy non-CCM subjects. Genetic aberrations, plasma molecules, and imaging biomarkers in a well characterized Mendelian neurovascular disease may also be applicable in the aging brain. Graphical abstract.

Distinct genetic interactions between multiple Vegf receptors are required for development of different blood vessel types in zebrafish. Proc Natl Acad Sci U S A 2006; 103:6554-9.

Abstract
Recent evidence indicates a specific role for vascular endothelial growth factor a (Vegfa) during artery development in both zebrafish and mouse embryos, whereas less is known about signals that govern vein formation. In zebrafish, loss of vegfa blocks segmental artery formation and reduces artery-specific gene expression, whereas veins are largely unaffected. Here, we describe a mutation in the zebrafish vegf receptor-2 homolog, kdra, which eliminates its kinase activity and leads to specific defects in artery development. We further find that Flt4, a receptor for Vegfc, cooperates with Kdr during artery morphogenesis, but not differentiation. We also identify an additional zebrafish vegfr-2 ortholog, referred to as kdrb, which can partially compensate for loss of kdra but is dispensable for vascular development in wild-type embryos. Interestingly, we find that these Vegf receptors are also required for formation of veins but in distinct genetic interactions that differ from those required for artery development. Taken together, our results indicate that formation of arteries and veins in the embryo is governed in part by different Vegf receptor combinations and suggest a genetic mechanism for generating blood vessel diversity during vertebrate development.
