BACKGROUND: -A continuous relationship between reductions in low-density lipoprotein cholesterol (LDL-C) and major adverse cardiovascular events (MACE) has been observed in statin and ezetimibe outcomes trials, down to achieved levels of 54 mg/dL. However, it is uncertain whether this relationship extends to LDL-C levels <50 mg/dL. We assessed the relationship between additional LDL-C, non-high-density lipoprotein cholesterol (non-HDL-C), and apolipoprotein B100 (apoB) reductions and MACE among patients within the ODYSSEY trials that compared alirocumab versus controls (placebo/ezetimibe), mainly as add on to maximally tolerated statin...

Psoriasis is a chronic systemic immune-mediated inflammatory dermatosis associated with several comorbidities. Psoriasis patients are at increased risk of developing cardiovascular diseases (CVD), namely, coronary heart disease, stroke or peripheral vascular disease, and psoriasis seems to be an independent cardiovascular risk factor. Antipsoriatic systemic therapy, especially anti-tumor necrosis factor (TNF)-α, seems to exert a beneficial effect on these comorbidities. The purpose of this study was: (i) to measure the level of cardiovascular serum markers in psoriasis patients in comparison with healthy volunteers; and (ii) to compare the serum level of the same markers in patients before and 3 months after adalimumab therapy...

Studies have demonstrated the significant role of cholesterol and lipoprotein metabolism in the progression of cancer. The SCARB1 gene encodes the scavenger receptor class B type I (SR-BI), which is an 82-kDa glycoprotein with two transmembrane domains separated by a large extracellular loop. SR-BI plays an important role in the regulation of cholesterol exchange between cells and high-density lipoproteins. Accordingly, hepatic SR-BI has been shown to play an essential role in the regulation of the reverse cholesterol transport pathway, which promotes the removal and excretion of excess body cholesterol...

Although statins and other pharmacological approaches have improved the management of lipid abnormalities, there exists a need for newer treatment modalities especially for the management of hypertriglyceridemia. Lipoprotein lipase (LPL), by promoting hydrolytic cleavage of the triglyceride core of lipoproteins, is a crucial node in the management of plasma lipid levels. Although LPL expression and activity modulation is observed as a pleiotropic action of some the commonly used lipid lowering drugs, the deliberate development of drugs targeting LPL has not occurred yet...

INTRODUCTION: Diabetic erectile dysfunction is a disease mostly of vascular origin and men with diabetic erectile dysfunction respond poorly to oral phosphodiesterase-5 inhibitors. Hepatocyte growth factor (HGF) is a pleiotropic factor that plays an essential role in the regulation of cell proliferation, survival, and angiogenesis. AIM: To determine the effectiveness of recombinant human (rh)-HGF in restoring erectile function in diabetic mice. METHODS: Four groups of mice were used: control non-diabetic mice and streptozotocin-induced diabetic mice receiving two successive intracavernous injections of phosphate buffered saline (days -3 and 0), a single intracavernous injection of rh-HGF (day 0), or two successive intracavernous injections of rh-HGF (days -3 and 0)...

Lipids in the body are transported via lipoproteins that are nanoparticles comprised of lipids and amphipathic proteins termed apolipoproteins. This family of lipid surface-binding proteins is over-represented in human amyloid diseases. In particular, all major proteins of high-density lipoproteins (HDL), including apoA-I, apoA-II and serum amyloid A, can cause systemic amyloidoses in humans upon protein mutations, post-translational modifications or overproduction. Here, we begin to explore how the HDL lipid composition influences amyloid deposition by apoA-I and related proteins...

The challenge of effectively delivering therapeutic agents to the brain has created an entire field of active research devoted to overcoming the blood brain barrier (BBB) and efficiently delivering drugs to the brain. Angiopep-2 can trigger transcytosis and traverse the BBB by recognizing low-density lipoprotein related protein-1 (LRP-1) expressed on the brain capillary endothelial cells. Here, we designed a novel strategy for the delivery of drugs to the brain. The novel drug delivery system was a combination of a receptor-targeting ligand, such as low-density lipoprotein related protein 1, and a cell-penetrating peptide (CPP)...

Poly (ADP-ribose) polymerase (PARP) plays an important role in endothelial dysfunction, leading to atherogenesis and vascular-related diseases. However, whether PARP regulates nitric oxide (NO), a key regulator of endothelial function, is unclear so far. We investigated whether inhibition of PARP-1, the most abundant PARP isoform, prevents atherogenesis by regulating NO production and tried to elucidate the possible mechanisms involved in this phenomenon. In apolipoprotein E-deficient (apoE(-/-) ) mice fed a high-cholesterol diet for 12 weeks, PARP-1 inhibition via treatment with 3,4-dihydro-54-(1-piperindinyl) butoxy-1(2H)-isoquinoline (DPQ) or PARP-1 gene knockoutreduced aortic atherosclerotic plaque areas (49% and 46%, respectively)...

Ethanol abuse is a serious public health problem that is associated with several stages of alcoholic liver disease (ALD) and a high incidence of morbidity and mortality. Alcoholic fatty liver disease (AFLD), the earliest stage of ALD, is a multifactorial injury that involves oxidative stress and disruptions of lipid metabolism. Although benign and reversible, no pharmacological treatments are available for this condition. In the present study, we induced AFLD in mice with 10% ethanol and a low-protein diet and then orally treated them with a hydroethanolic extract of Baccharis trimera (HEBT; 30 mg kg(-1))...

Statin therapy is associated with a slightly increased risk of developing diabetes mellitus and insulin resistance in patients without diabetes. Ezetimibe combined with statins may be considered for high-risk patients who do not achieve optimal low-density lipoprotein cholesterol lowering on statin monotherapy or who are statin intolerant. Changes in fasting serum glucose (FSG) levels during ezetimibe, ezetimibe/statin, and statin treatments were assessed using data pooled from clinical trials in hypercholesterolemic and heterozygous familial hypercholesterolemic patients, who were or were not receiving statin therapy...
