Blood Pressure Control by a Secreted FGFBP1 (Fibroblast Growth Factor-Binding Protein).

ABSTRACT: Fibroblast growth factors (FGFs) participate in organ development and tissue maintenance, as well as the control of vascular function. The paracrine-acting FGFs are stored in the extracellular matrix, and their release is controlled by a secreted FGF-binding protein (FGF-BP, FGFBP1, and BP1) that modulates FGF receptor signaling. A genetic polymorphism in the human FGFBP1 gene was associated with higher gene expression and an increased risk of familial hypertension. Here, we report on the effects of inducible BP1 expression in a transgenic mouse model. Induction of BP1 expression in adult animals leads to a sustained rise in mean arterial pressure by >30 mm Hg. The hypertensive effect of BP1 expression is prevented by candesartan, an angiotensin II (AngII) receptor antagonist, or by
