OBJECTIVES Relaxation of vascular smooth muscle (VSM) requires re-uptake of cytosolic Ca(2+) into the sarcoplasmic reticulum (SR) via the Sarco/Endoplasmic Reticulum Ca(2+) ATPase (SERCA), or extrusion via the Plasma Membrane Ca(2+) ATPase (PMCA) or sodium Ca(2+) exchanger (NCX). Peroxynitrite, a reactive species formed in vascular inflammatory diseases,(More)
All animal procedures were performed in accordance with UK Home Office Guidance on the operation of the Animals (Scientific Procedures) Act 1986 and institutional ethical approval (PPL60/4114 and PPL 60/4429). Male white Landrace pigs (SAC Commercial Ltd, Edinburgh, UK) and miR-21 knockout mice (1) were maintained on a 12 hour light/dark cycle with free(More)
AIMS The long-term failure of autologous saphenous vein bypass grafts due to neointimal thickening is a major clinical burden. Identifying novel strategies to prevent neointimal thickening is important. Thus, this study aimed to identify microRNAs (miRNAs) that are dysregulated during neointimal formation and determine their pathophysiological relevance(More)
OBJECTIVE The aim of this study was to assess the efficacy of stent-based delivery of succinobucol alone and in combination with rapamycin in a porcine coronary model. BACKGROUND Current drugs and polymers used to coat coronary stents remain suboptimal in terms of long term efficacy and safety. Succinobucol is a novel derivative of probucol with improved(More)
The oxidation of low-density lipoprotein (LDL) is thought to contribute to atherogenesis, which is an inflammatory disease involving activation of phagocytic cells. Myeloperoxidase, an enzyme which is able to produce hypochlorous acid (HOCl), is released from these phagocytic cells, and has been found in an active form in atherosclerotic plaques. HOCl can(More)
OBJECTIVE The balance between coronary endothelial dysfunction and repair is influenced by many protective and deleterious factors circulating in the blood. We studied the relationship between oxidised low-density lipoprotein (oxLDL), circulating endothelial progenitor cells (EPCs) and coronary endothelial function in patients with stable coronary heart(More)

Objective. Emerging evidence suggests an important role for mast cells in vein graft failure. This study addressed the hypothesis that perivascular mast cells regulate in situ vascular inflammatory and proliferative responses and subsequent vein graft neointimal lesion formation, using an optimized local mast cell reconstitution method. Methods and Results.(More)
AMP-activated protein kinase (AMPK) is present in the arterial wall and is activated in response to cellular stressors that raise AMP relative to ADP/ATP. Activation of AMPK in vivo lowers blood pressure but the influence of hyperlipidemia on this response has not been studied. ApoE(-/-) mice on high fat diet for 6weeks and age-matched controls were treated(More)
