As mentioned above, it would be exciting to investigate if the expressions of ADAM10, ADAM17, MMP2, and other MMPs are altered in endothelial cells in pathological conditions, such as cardiac surgery and cavernous cerebral malformations, thereby influencing Robo4 shedding to affect Robo4 signaling, attributing to the related pathogenesis. This evidence concerns the gene ADAM10 and cerebral cavernous malformation.
