Simvastatin is currently one of the most common drugs for old patients with hyperlipidemia, hypercholesterolemia and atherosclerotic diseases by reducing cholesterol level and anti-lipid properties. Importantly, simvastatin has also been reported to have anti-tumor effect, but the underlying mechanism is largely unknown. We collected several human bladder samples and performed microarray. Data analysis suggested bladder cancer (BCa) was significantly associated with fatty acid/lipid metabolism via PPAR signalling pathway...

Being a potential candidate for stroke treatment, bone marrow stromal cells (BMSCs) have been demonstrated to be able to enhance angiogenesis and proliferation of reactive astrocytes which subsequently lead to the amelioration of neurological injury. Increasing evidences further indicate combined BMSCs with certain agent such as simvastatin may have improved therapeutic effect. Sodium Ferulate (SF) and n-butylidenephthalide (BP), two main components of Radix Angelica Sinensis, are proved to be the important regulators of stem cells in cell migration, differentiation and pluripotency maintenance...

BACKGROUND: Non-alcoholic fatty liver disease is the most common form of chronic liver disease in industrialized countries. Recent studies have highlighted the association between peroxisomal dysfunction and hepatic steatosis. Peroxisomes are intracellular organelles that contribute to several crucial metabolic processes, such as facilitation of mitochondrial fatty acid oxidation (FAO) and removal of reactive oxygen species through catalase or plasmalogen synthesis. Statins are known to prevent hepatic steatosis and non-alcoholic steatohepatitis (NASH), but underlying mechanisms of this prevention are largely unknown...

Triple-negative breast cancer (TNBC), which accounts for 15-20% of all breast cancers, does not express estrogen receptor (ER) or progesterone receptor (PR) and lacks human epidermal growth factor receptor 2 (HER2) overexpression or amplification. These tumors have a more aggressive phenotype and a poorer prognosis due to the high propensity for metastatic progression and absence of specific targeted treatments. Patients with TNBC do not benefit from hormonal or trastuzumab-based targeted therapies because of the loss of target receptors...

Statins are a cornerstone of the pharmacologic treatment and prevention of atherosclerotic cardiovascular disease. Atherosclerotic disease is a predominant cause of mortality and morbidity worldwide. Statins are among the most commonly prescribed classes of medications, and their prescribing indications and target patient populations have been significantly expanded in the official guidelines recently published by the American and European expert panels. Adverse effects of statin pharmacotherapy, however, result in significant cost and morbidity and can lead to nonadherence and discontinuation of therapy...

The clinical relevance of the drug-drug interaction simvastatin and amlodipine is appraised controversially by german simvastatin Summary of Product Characteristics (SPCs) and different drug interaction databases. Results of clinical trials have shown that simultaneous administration of simvastatin and amlodipine can increase simvastatin bioavailability. However, it is unclear whether this increase is associated with a higher risk for adverse drug events. So far there is no evidence that the combination might increase cases of myopathy or rhabdomyolysis...

Psychiatric adverse drug reactions (ADRs) have been reported with statin use, but the literature regarding statin-associated mood/behavioral changes remains limited. We sought to elicit information germane to natural history and characteristics of central nervous system/behavioral changes in apparent connection with statin and/or cholesterol-lowering drug use, and delineate mechanisms that may bear on an association. Participants (and/or proxies) self-referred with behavioral and/or mood changes in apparent association with statins completed a survey eliciting cholesterol-lowering drug history, character and impact of behavioral/mood effect, time-course of onset and recovery in relation to drug use/modification, co-occurrence of recognized statin-associated ADRs, and factors relevant to ADR causality determination...

Simvastatin is a 3-hydroxy-3-methylglutaryl-CoA reductase inhibitor widely used for the treatment of hypercholesterolemia. Recent data indicates that simvastatin increases the risk of new-onset diabetes by impairing both insulin secretion and insulin sensitivity. However, systematic evaluation of mechanistic pathways is lacking. We aimed to explore the effects of simvastatin on glucose uptake and underlying mechanisms using L6 skeletal muscle myotubes. We performed our experiments at basal and insulin-stimulated conditions, at normal (5...

Medicago sativa L. is the most important cultivated herbage known as "the king of forage" and "feed queen" in the world. Eight new chalcones (1-8), and twelve known chalcones (9-20) were isolated from the aerial parts of M. sativa for the first time. Their structures were identified by extensive spectral data and references. The hypolipidemic and anti-angiogenic activities of compounds (1-20) were evaluated for the first time. Compounds 3, 4, 11, 12, and 20 (10 μM) exhibited significant hypolipidemic activities by measuring the triglyceride content in HepG2 cells with Simvastatin as positive control...

AIM: Publicly-funded atorvastatin required prior approval until September 2010 whereas simvastatin did not. Our aim was to examine if overall statin dispensing and atorvastatin dispensing among patients hospitalised for cardiovascular disease (CVD) differed systematically across sociodemographic groups during and after special authority criteria. METHOD: National medication dispensing data were anonymously linked to patients hospitalised across New Zealand with CVD and discharged between 1/07/2009-31/12/2009 when special authority criteria applied and 1/09/2010-28/02/2011 after restrictions ceased...

Diabetes and obesity are associated with non-alcoholic steatohepatitis and an increased incidence of hepatocellular carcinoma (HCC). TAZ and YAP are equivalently placed downstream effectors of the Hippo pathway with oncogenic roles in human cancers. Statins are commonly used to patients with metabolic problems as hypercholesterolemia. Statins also have anti-cancer properties, and the cross-talk between mevalonate pathway and Hippo pathway was known. The aim of this study is to confirm the statin's anti-cancer effects on HCC cells and its survival benefits in HCC patients with curative surgery...
