| Beschreibung: | Vascular calcification is an actively regulated process driven by vascular smooth muscle cell (VSMC) osteogenic reprogramming and promoted by oxidative stress and extracellular matrix remodeling. We investigated whether the novel histone deacetylase inhibitor YAK577 mitigates calcification by modulating an MMP14–NOX2/ROS-associated pathway in calcification medium (CM)-treated VSMCs and a vitamin D3-induced arterial calcification model in 8-week-old male C57BL/6N mice. Calcification was assessed by Alizarin Red S/von Kossa staining and calcium quantification; osteogenic markers (BMP2, RUNX2, MSX2) and MMPs were examined by qRT-PCR and immunoblotting; intracellular ROS was measured by DHE staining with N-acetylcysteine as an antioxidant control; and MMP14 was manipulated by siRNA knockdown or plasmid overexpression. YAK577 was non-cytotoxic at effective concentrations and reduced CM-induced calcium deposition and osteogenic marker expression. YAK577 reduced MMP14 expression and suppressed CM-induced NOX2/p47phox activation and ROS accumulation, while GSK2795039 attenuated CM-induced DHE fluorescence. MMP14 silencing attenuated, whereas MMP14 overexpression enhanced, osteogenic signaling and increased NOX2. In vivo, YAK577 reduced vitamin D3-induced aortic calcium burden, histological calcification, and the expression of MMP14, NOX2, and osteogenic markers. These data support a working model in which YAK577 alleviates vascular calcification, at least in part, by suppressing an MMP14-associated NOX2/p47phox–ROS axis. | |||||||
