: The introduction of new agents in multiple myeloma therapy has increased the overall response rate and improved clinical outcomes, but the increased risk of thrombotic complications impairs the quality of life of patient and the optimal thromboprophylaxis remains unknown. Increasing evidence has shown that statins can prevent venous thrombosis. Hence, we investigated the effects of simvastatin on multiple myeloma serum-related haemostatic imbalance in endothelial cells in vitro. The effects of simvastatin on procoagulant and anticoagulant protein expression were assessed on mixed multiple myeloma serum-treated human umbilical vein endothelial cells (HUVECs)...

PROBLEM: Oxidative stress (OS)-induced, p38 mitogen-activated protein kinase (p38MAPK)-mediated chorioamniotic senescence and inflammation (senescence-associated secretory phenotype [SASP]) are associated with parturition. In response to OS-inducing risk factors, premature senescence contributes to preterm premature rupture of the membranes (pPROM) and spontaneous preterm birth (PTB). We determined the effect of simvastatin, rosuvastatin, and progesterone in downregulating p38MAPK-mediated senescence and SASP...

Simvastatin (SIM), a hypocholesterolaemic compound, is among the most prescribed pharmaceuticals for cardiovascular disease prevention worldwide. Several studies have shown that acute exposure to SIM causes multiple adverse effects in aquatic organisms. However, uncertainties still remain regarding the chronic effects of SIM in aquatic ecosystems. Therefore, the present study aimed to investigate the effects of SIM in the model freshwater teleost zebrafish (Danio rerio) following a chronic exposure (90 days) to environmentally relevant concentrations ranging from 8 ng/L to 1000 ng/L...

Evidence suggests that oxidative stress is involved in the pathogenesis of Parkinson disease (PD). Simvastatin has been suggested to protect against oxidative stress in several diseases. However, the molecular mechanisms by which simvastatin protects against neuropathology and oxidative damage in PD are poorly elucidated. In this study, we aimed to investigate the potential neuroprotective effects of simvastatin owing to its anti-oxidative properties in 6-hydroxydopamine (6-OHDA)-treated SH-SY5Y cells and mice...

Statins are HMG-CoA reductase inhibitors with lipid-lowering effect and commonly used to reduce cardiovascular risk in diabetic patients. The present study investigates the ameliorative effect of simvastatin (SIM) on diabetic nephropathy in rats, pointing to its anti-apoptotic and anti-oxidative stress efficacies. Diabetes was induced by a single intraperitoneal injection of 55 mg/kg body weight streptozotocin (STZ) and both control and diabetic rats received 10 mg/kg SIM for 90 days. Treatment with SIM diminished the body weight loss, blood glucose and, serum creatinine, urea and uric acid in diabetic rats...

Cell plasticity of 'stem-like' cancer-initiating cells (CICs) is a hallmark of cancer, allowing metastasis and cancer progression. Here, we studied whether simvastatin, a lipophilic statin, could impair the metastatic potential of CICs in high-grade serous ovarian cancer (HGS-ovC), the most lethal among the gynecologic malignancies. qPCR, immunoblotting, and immunohistochemistry were used to assess simvastatin effects on proteins involved in stemness and epithelial-mesenchymal cell plasticity (EMT). Its effects on tumor growth and metastasis were evaluated using different models (e...

Simvastatin (Sim) is a widely known drug in the treatment of hyperlipidemia that has attracted so much attention in bone regeneration based on its potential osteoanabolic effect. However, repurposing of Sim in bone regeneration will require suitable delivery systems that can negate undesirable off-target/side effects. In this study, we have investigated a new lipid nanoparticle (NP) platform that was fabricated using a binary blend of emulsifying wax (Ewax) and glyceryl monooleate (GMO). Using the binary matrix materials, NPs loaded with Sim (0-500 µg/mL) were prepared and showed an average particle size of about 150 nm...
