Xuezhikang (XZK), an extract of Chinese red yeast rice, is recommended as an optimal choice for patients with coronary heart disease (CHD) with markedly elevated triglyceride (TG) levels. This study was designed to compare the hypotriglyceridemic effects between XZK and simvastatin. The role of apolipoprotein A5 (apoA5), a key regulator of TG metabolism and a target gene of peroxisome prolifera...

Simvastatin, an inhibitor of HMG-CoA reductase, is a potent inhibitor of cholesterol biosynthesis and has beneficial effects in the primary and secondary prevention of cardiovascular diseases. In this study, we report the effects of simvastatin on catecholamine secretion and synthesis in cultured bovine adrenal medullary cells used as a model of sympathetic neurons. Simvastatin inhibited catech...

Statins purportedly exert anti-tumoral effects on breast cancer. However, the biologic mechanisms for these actions are not fully elucidated. The aims of this study were 1) to explore the effects of simvastatin on apoptosis, proliferation as well as PI3K/Akt/mTOR and MAPK/ERK pathway in a window-of-opportunity breast cancer trial; 2) to further confirm findings from the clinical trial by functi...

BACKGROUND Simvastatin is a widely used medication in cardiac care. Here we evaluate the role of ATP sensitive potassium (KATP) channels in simvastatin induced renal protection after renal ischemia/reperfusion (I/R) injury. METHODS A total of 81 male Wistar rats, were treated with simvastatin (10 and 20mg/kg/day; gavage, one week). Some groups received glibenclamide (KATP channel inhibitor; 5...

Objective To investigate the impact of simvastatin on blood lipid and the incidence of atrial fibrillation and ischemic-related events in patients with acute myocardial infarction accompanied by paroxysmal atrial fibrillation. Methods One hundred and three patients with acute myocardial infarction and paroxysmal atrial fibrillation were selected as subjects, and were divided into a simvastatin ...

AIMS Statins can ameliorate atherosclerosis by inhibition of cholesterol biosynthesis or by modulation of inflammation. In earlier work, we showed that homocysteine (Hcy) reduced synthesis of apolipoprotein A-I (ApoA-I). Our goal in this study was to determine whether Hcy could interfere with the ability of simvastatin to increase ApoA-I synthesis or to modify statin-dependent regulation of inf...

OBJECTIVE Evaluating the effect of preconditioning with simvastatin in acute kidney injury induced by sepsis. METHOD Male adult Wistar rats were divided into the following groups: SHAM (control); SHAM+Statin (0.5 mg/kg simvastatin, orally); Sepsis (cecal puncture ligation - CPL); Sepsis+Statin. Physiological parameters, peritoneal fluid culture, renal function, oxidative metabolites, severity...

INTRODUCTION Earlier work indicates that the cholesterol-lowering drug, simvastatin, is anabolic to chondrogenic expression of rat intervertebral disc (IVD) cells, which suggests a potential role for simvastatin in IVD regeneration. In this study, we expand on our earlier work to test the effectiveness of simvastatin on disc degeneration utilizing a rat tail disc degeneration model. METHODS 3...

Reactive oxygen species‑induced cyclophilin A (CyPA) release from vascular smooth muscle cells (VSMCs) may be inhibited by simvastatin in vitro. The present study aimed to further examine the effect of simvastatin on serum CyPA levels and the basigin (CD147)‑extracellular signal‑regulated kinase (ERK) 1/2‑cyclin pathway during thoracic aorta remodeling. The mechanisms through which simvastatin ...
