abstract = {Retinopathy of prematurity causes visual impairment due to
destructive neoangiogenesis after degeneration of the
retinal microvasculature. This study was aimed at analyzing
whether local delivery of Semaphorin-3C (Sema3C) suppresses
pathological retinal angiogenesis. Sema3C exerted potent
inhibiting effects in cellular models of angiogenesis. In an
endothelial cell xenotransplantation assay, Sema3C acted
primarily on immature microvessels by inducing endothelial
cell apoptosis. Intravitreal administration of recombinant
Sema3C disrupted endothelial tip cell formation and
cell-cell contacts, which led to decreased vascular bed
expansion and vessel branching in the growing retinal
vasculature of newborn mice, while not affecting mature
vessels in the adult retina. Sema3C administration strongly
inhibited the formation of pathological pre-retinal vascular
tufts during oxygen-induced retinopathy. Mechanistically,
Sema3C signaled through the receptors Neuropilin-1 and
PlexinD1, which were strongly expressed on vascular tufts,
induced VE-cadherin internalization, and abrogated vascular
endothelial growth factor (VEGF)-induced activation of the
kinases AKT, FAK, and p38MAPK. This disrupted endothelial
cell junctions, focal adhesions, and cytoskeleton assembly
resulted in decreased cell migration and survival. Thus,
this study identified Sema3C as a potent and selective
inhibitor of pathological retinal angiogenesis.},
