Aging is associated with impairment of endothelial nitric oxide synthase (eNOS) and progressive reduction in endothelial function. A genetic study on long-living individuals - who are characterized by delays in aging and in the onset of cardiovascular disease - previously revealed I229V ( rs2070325 ) in BPIFB4 as a longevity-associated variant (LAV); the LAV protein enhanced endothelial NO production and vasorelaxation through a PERK/14-3-3/HSP90 signal. Here, we further characterize the molecular mechanisms underlying LAV-BPIFB4-dependent enhancement of vascular function.

Abstract
Aging is associated with impairment of endothelial nitric oxide synthase (eNOS) and progressive reduction in endothelial function. A genetic study on long-living individuals - who are characterized by delays in aging and in the onset of cardiovascular disease - previously revealed I229V ( rs2070325 ) in BPIFB4 as a longevity-associated variant (LAV); the LAV protein enhanced endothelial NO production and vasorelaxation through a PERK/14-3-3/HSP90 signal. Here, we further characterize the molecular mechanisms underlying LAV-BPIFB4-dependent enhancement of vascular function.File in questo prodotto:
