Premature arterial stiffening in Hutchinson-Gilford Progeria Syndrome linked to early induction of Lysyl Oxidase (LOX) and corrected by LOX inhibition

Abstract: Arterial stiffening is a hallmark of premature aging in Hutchinson-Gilford Progeria Syndrome (HGPS), but the key molecular regulators initiating arterial stiffening in HGPS remain unknown.To identify these early events, we compared arterial mechanics and ECM remodeling in very young HGPS (LMNA G609G/G609G ) mice to those of age-matched and much older wild-type mice.Biaxial inflation-extension tests of carotid arteries of 2-month mice showed that circumferential stiffness of HGPS arteries was comparable to that… Show more
