This study aimed to examine the protective effect of Artemisia iwayomogi extract (AI) against hypertriglyceridemia induced by a high-fat diet (HFD) in mice and to uncover the underlying molecular mechanisms. C57BL/6N mice were fed chow, HFD, HFD + 0.1% AI, HFD + 0.25% AI, or HFD + 0.5% AI for 10 weeks. The addition of 0.25% and 0.5% AI resulted in dose-dependent improvements in the major parameters of hypertriglyceridemia, including plasma triglyceride, free fatty acids, apolipoprotein B, and lipoprotein lipase, with parallel reductions in body weight gain, hepatic lipid accumulation, and insulin resistance...

Despite the fact that ischemic stroke has been considered a leading cause of mortality in the world, recent advances in our understanding of the pathophysiological mechanisms underlying the ischemic injury and the treatment of acute ischemic stroke patients have led to a sharp decrease in the number of stroke deaths. However, this decrease in stroke mortality has also led to an increase in the number of patients that survive the acute ischemic injury with different degrees of disability. Unfortunately, to this date we do not have an effective therapeutic strategy to promote neurological recovery in these growing population of stroke survivors...

Injury and endothelial cell apoptosis are hall marks of atherosclerosis (AS). However, the mechanisms underlying its pathogenesis remain ill-defined. Recent evidence of a role for microRNAs in AS-associated endothelial cell apoptosis encouraged us to address this question. Here, AS was developed in ApoE (-/-) mice supplied with a high-fat diet (HFD), compared to ApoE (-/-) mice supplied with a normal diet (ND). Mouse endothelial cells were isolated from the aortic arch using flow cytometry based on their expression of CD31...

Statins are the first-line treatment for hypercholesterolemic patients. Herein, the effects of three statins on complex formation between proprotein convertase subtilisin-kexin 9 (PCSK9) and the low density lipoprotein receptor (LDLR), a critical step for the PCSK9-dependent degradation of LDLR in the lysosome, were examined. Human hepatocyte-like C3A cells grown in control (containing 10% fetal bovine serum) or MITO+ (supplemented with BD™ MITO + serum extender) medium were also treated with atorvastatin (Atorv), lovastatin (Lov), or pravastatin (Prav) for 24 h...

The effects of water supplementation of chelated trace minerals (CTM, which is named Bonzaplex designed with chelate compounds technology) on growth performance, apparent total tract digestibility (ATTD) of minerals, and some blood metabolites, TM, and antioxidant enzyme values in African ostriches were investigated from 8 to 12 months of age. A total of 20 8-month-old ostriches (five birds in five replicate pens) was randomly allocated into one of the following four treatments: (1) control (basal diet + tap water), (2) low CTM (basal diet +100 mg/bird/day CTM powder in tap water), (3) medium CTM (basal diet +1 g/bird/day CTM powder in tap water), and (4) high CTM (basal diet +2 g/bird/day CTM powder in tap water)...

Protein O-mannosylation is crucial for the biology of Mycobacterium tuberculosis but the key mannosylated protein(s) involved and its(their) underlying function(s) remain unknown. Here, we demonstrated that the M. tuberculosis mutant (Δpmt) deficient for protein O-mannosylation exhibits enhanced release of lipoarabinomannan (LAM) in a complex with LprG, a lipoprotein required for LAM translocation to the cell surface. We determined that LprG is O-mannosylated at a unique threonine position by mass spectrometry analyses of the purified protein...

BACKGROUND: Lipoprotein(a) [Lp(a)] is an inherited atherogenic lipoprotein and an independent risk factor for atherosclerotic cardiovascular disease; however, its clinical role remains limited. OBJECTIVE: We hypothesized that Lp(a) screening in high cardiovascular risk patients could provide insight into disease pathogenesis and modify physician behavior for treatment intensification targeting traditional risk factors when Lp(a)-related risk was identified. METHODS: We screened 113 patients presenting electively for percutaneous coronary intervention (PCI) for Lp(a) who met any of the following criteria: (1) premature coronary artery disease (male age <55 years, female age <65 years); (2) family history of premature coronary artery disease; (3) progression to PCI despite well-controlled traditional risk factors (blood pressure <140/90 mm Hg, and low-density lipoprotein cholesterol <100 mg/dL, and HbA1c <7%, and nonsmoker); or (4) progression to PCI despite at least moderate intensity statin use (simvastatin 40, atorvastatin 40-80, or rosuvastatin 20-40 mg daily)...

BACKGROUND: Familial hypercholesterolemia (FH) is a disease characterized by increased low-density lipoprotein cholesterol and premature cardiovascular disease (CVD) but there is marked individuality in the occurrence of CVD events. Recently, the Montreal-FH-SCORE (MFHS) has been shown to stratify CVD frequency in FH subjects, but this score has not yet been validated. OBJECTIVE: The aims of the present study were to conduct an independent external validation of the MFHS in a retrospective cohort of heterozygous FH and to identify additional variables that could significantly improve the prediction of prevalent CVD...

There have been striking associations of cardiovascular diseases (e.g., atherosclerosis) and hypercholesterolemia with increased risk of neurodegeneration including Alzheimer's disease (AD). Low-density lipoprotein (LDL), a cardiovascular risk factor, plays a crucial role in AD pathogenesis; further, L5, a human plasma LDL fraction with high electronegativity, may be a factor contributing to AD-type dementia. Although L5 contributing to atherosclerosis progression has been studied, its role in inducing neurodegeneration remains unclear...

Introduction Increasing high-density lipoprotein(HDL) cholesterol levels predict improved cardiovascular outcomes. However, inhibiting cholesteryl ester transfer protein (CETP) to increase HDL cholesterol, with the 'cetrapibs' (torcetrapib and dalcetrapib), did not improve cardiovascular clinical outcomes. Despite these findings, the clinical outcomes trial with evacetrapib continued. Areas covered Treatment with evacetrapib increased the levels of HDL by ~130%, and decreased low-density lipoprotein (LDL) cholesterol by ~37%...

Ten-eleven translocation-2 (TET2) protein is a DNA demethylase that regulates gene expression through DNA demethylation and also plays important roles in various diseases including atherosclerosis. Endothelial dysfunction represents an early key event in atherosclerotic disease. The cystathionine-γ-lyase (CSE)/hydrogen sulfide (H2S) is a key endogenous system with protective effects on endothelial functions. In this study, we examined how TET2 regulates oxidized low-density lipoprotein (oxLDL)-induced dysfunction of human umbilical vein endothelial cells (HUVECs) and determined the role of the CSE/H2S system...

OBJECTIVE: Despite the early promising results of (18)F-fluorodeoxyglucose positron emission tomography for assessment of vessel wall inflammation, its accuracy in prospective identification of vulnerable plaques has remained limited. Additionally, previous studies have indicated that (18)F-fluorodeoxyglucose uptake alone may not allow for accurate identification of specific macrophage activation states. We aimed to determine whether combined measurement of glucose and glutamine accumulation-the 2 most important bioenergetic substrates for macrophages-improves the distinction of macrophage inflammatory states and can be utilized to image atherosclerosis...
