OBJECTIVE Carvacrol (2-methyl-5-(1-methylethyl) phenol), a cyclic monoterpene, exerts protective activities in a variety of pathological states including tumor growth, inflammation, and oxidative stress. However, it is unknown whether carvacrol affects events in vascular cells during the development of atherosclerotic neointima. We investigated the effects(More)
OBJECTIVE Compound K (CK), an intestinal metabolite of ginsenosides, has pharmacological properties such as anti-angiogenesis, anti-inflammation, anti-platelet and anti-cancer activities. In the present study, we investigated the inhibitory effect of CK on vascular smooth muscle cell (VSMC) proliferation and migration in vitro and neointima formation in a(More)
AIMS DJ-1/park7 is a ubiquitously expressed multifunctional protein that plays essential roles in a variety of cells. However, its function in the vascular system has not been determined. We investigated the protective roles of DJ-1/park7 in vascular disorders, especially in neointimal hyperplasia. METHODS AND RESULTS DJ-1/park7 was strongly expressed in(More)
3-Morpholinosydnonimine (SIN-1) affects vascular smooth muscle cell migration and proliferation, processes essential for atherosclerosis. However, the mechanism by which SIN-1 exerts these effects has not been elucidated. We used 2-DE followed by MALDI-TOF/TOF MS to identify responses in protein expression to SIN-1 in rat aortic smooth muscle.(More)
AIMS The purpose of this study is to explore whether antioxidant DJ-1 protein affects the atrophy of skeletal muscle cell induced by undernutrition. MAIN METHODS To determine cell atrophic responses, L6 cell line and skeletal primary cells from mouse hind limbs were cultivated under condition of FBS-free and low glucose. Changes of protein expression were(More)
OBJECTIVE DJ-1-a multifunctional protein responding to oxidative stress-is a possible regulator of the inflammatory response that plays an important role in atherosclerosis. Stromal cell-derived factor (SDF)-1 and its receptor, chemokine receptor type 4 (CXCR4), have been implicated in the recruitment of inflammatory cells during atherosclerosis. Here we(More)
BACKGROUND DJ-1 protein plays multifunctional roles including transcriptional regulation and scavenging oxidative stress; thus, it may be associated with the development of renal disorders. We investigated whether DJ-1 protein regulates the expression of (pro)renin receptor (PRR), a newly identified member of renin-angiotensin system. METHODS The levels(More)
Azole antifungals such as ketoconazole are generally known to induce a variety of heart function side effects, e.g., long-QT syndrome and ventricular arrhythmias. However, a clear mechanism for the action of ketoconazole in heart cells has not been reported. In the present study, we assessed the correlation between ketoconazole-induced apoptosis and the(More)
The rupture of an atherosclerotic plaque is one of the main causes of coronary artery thrombotic occlusion, leading to myocardial infarction. However, the exact mechanism and causal risk factors for plaque rupture remain unclear. To identify a potential molecule that can influence atherosclerotic plaque rupture, we investigated protein expression in serum(More)
