BACKGROUND
Insulin resistance is strongly associated with the development of type 2 diabetes and cardiovascular disease. However, the underlying mechanisms linking insulin resistance and the development of atherosclerosis have not been fully elucidated. Moreover, the protective effect of
Insulin resistance (IR) is associated with an increased risk of cardiovascular diseases. The obese Zucker rat (ZR) is a model of IR that shows markedly increased insulin and triglyceride concentrations without major changes in glucose. In this study, we evaluated the response of obese and lean ZR to
BACKGROUND
The common -514 C-T promoter polymorphism of the hepatic lipase gene (LIPC) and the cholesteryl ester transfer protein (CETP) gene TaqIB polymorphism affect atherogenesis. We investigated the potential relationship between these polymorphisms and the maximum-intima-media thickness (M-IMT)
The inhibition of neointima formation by drugs is a major goal to prevent restenosis following angioplasty. In the present study, the effect of etofibrate on blood lipids and vessels wall was investigated using a balloon injury rat model. Two weeks after ballooning the common carotid artery
Akkermansia muciniphila (A. muciniphila) is an intestinal commensal with anti-inflammatory properties both in the intestine and other organs. The aim is to investigate the effects of oral administration of A. muciniphila on lipid metabolism, immunity, and cuff-induced neointima We tested the hypothesis that hyperinsulinemia induces the suppression of protein tyrosine phosphatase 1B (PTP1B) function, leading to enhanced PDGF receptor (PDGFR) signaling and neointimal hyperplasia. Rats were implanted with insulin-releasing pellets or sham pellets. Blood glucose levels,
Sulforaphane (SFN), a dietary phase-2 enzyme inducer that mitigates cellular oxidative stress through nuclear factor erythroid 2-related factor 2 (Nrf2) activation, is known to exhibit beneficial effects in the vessel wall. For instance, it inhibits vascular smooth muscle cell (VSMC) proliferation,
BACKGROUND
Although activation of the complement system has been implicated in the progression of human atherosclerosis, its function during arterial remodeling after injury has not been investigated. Here, we examined the contribution of the complement cascade to neointima formation in
OBJECTIVE
To explore the related factors of optical coherence tomography (OCT) detected in-stent heterogeneous neointimal in coronary stents.
METHODS
A total of 143 cases of coronary heart disease patients with OCT detected in-stent neointimal hyperplasia in Fuwai hospital from September 2009 to
Studies performed during the last decade indicate that adipose tissue is not only a site of triglyceride storage but also an active endocrine organ which secretes many biologically active mediators referred to as "adipokines". In contrast to many adipokines which are overproduced in obese
Troglitazone, a thiazolidinedione derivative, overcomes insulin resistance through promoting insulin receptor function. However, the effect of the resultant enhancement of insulin action on the regulation of cellular proliferation remains unknown. We investigated the effect of troglitazone on
Immune/inflammatory responses of arterial vessel wall constituents to lipid metabolic disturbances have been postulated to contribute to the pathogenesis of atherosclerosis. Mycophenolate mofetil (MMF), an antiproliferative agent used in clinical transplantation, has been shown to inhibit smooth
BACKGROUND
Restenosis after revascularization procedures is accelerated in persons with type 2 diabetes.
OBJECTIVE
The current study tested the hypothesis that the neointimal response to endovascular injury is enhanced in female obese Zucker (OZ) rats, a model of type 2 diabetes.
METHODS
Animals
BACKGROUND
Estrogen-mediated cardiovascular protection is incompletely explained by its beneficial lipid-modifying effects. Previous studies interrogating direct vascular effects of estrogens have used models of either diet- or injury-induced atherosclerosis. The purpose of this study was to
BACKGROUND
Peri-strut low-intensity area (PLIA) is a typical image pattern of neointima detected by optical coherence tomography (OCT) after stent implantation. However, few studies evaluated the predictors and prognosis of the PLIA; therefore, we aimed to explore the genesis and prognosis of PLIA
