PURPOSE OF REVIEW: This study aimed to present the current information on the genetic background of dyslipidemias and provide insights into the complex pathophysiological role of several plasma lipids/lipoproteins in the pathogenesis of atherosclerotic cardiovascular disease. Furthermore, we aim to summarize established therapies and describe the scientific rationale for the development of novel therapeutic strategies. RECENT FINDINGS: Evidence from genetic studies suggests that besides lowering low-density lipoprotein cholesterol, pharmacological reduction of triglyceride-rich lipoproteins, or lipoprotein(a) will reduce risk for coronary heart disease...

OBJECTIVE: The aim of the present study was to investigate the effects of hyperlipidemia on histological changes and apoptosis in submandibular glands using apolipoprotein E (apoE)-deficient rats. DESIGN: Histopathological findings related to induced apoptosis in the submandibular glands were compared between apoE-deficient rats (n=6; male; age, 16 weeks) and the corresponding wild-type rats (n=6). RESULTS: ApoE-deficient rats showed significantly higher plasma levels of oxidized low-density lipoprotein (LDL), total cholesterol, very LDL and LDL, and lower plasma levels of high-density lipoprotein when compared to control rats (P<0...

Association of hypercholesterolemia and atherosclerotic cardiovascular disease (ASCVD) is well established. Reducing low-density lipoprotein-cholesterol (LDL-C) and raising high-density lipoprotein-cholesterol (HDL-C) have been the therapeutic targets to reduce the risk of ASCVD. Cholesterol-lowering medications have been used to provide both primary and secondary prevention of ASCVD for many years by reducing the absorption and reabsorption, promoting excretion, or decreasing the synthesis of cholesterol. Within the past five years, several new classes of cholesterol-lowering drugs have been tested and approved for patients with hypercholesterolemia that are not well controlled by conventional therapy (ezetimibe, bile-acid sequestrants, and statins)...

Nonalcoholic fatty liver disease (NAFLD) spans steatosis through nonalcoholic steatohepatis, cirrhosis, and hepatocellular carcinoma (HCC) associated with striking systemic features and excess cardiovascular and liver-related mortality. The pathogenesis of NAFLD is complex and multifactorial. Endocrine derangements are closely linked with dysmetabolic traits. For example, in animal and human studies, female sex is protected from dysmetabolism thanks to young individuals' ability to partition fatty acids towards ketone body production rather than very low density lipoprotein (VLDL)-triacylglycerol, and to sex-specific browning of white adipose tissue...

OBJECTIVE: The "lipid hypothesis" determined that saturated fatty acid (SFA) raises low-density lipoprotein cholesterol, thereby increasing the risk for metabolic syndrome (MetS). The aim of this study was to investigate the effect of subchronic withdrawal from a high-carbohydrate, high-saturated fat (HCHF) diet during MetS with reference to changes in deleterious SFA (C12:0, lauric acid; C14:0, myristic acid; C16:0, palmitic acid; C18:0, stearic acid) distribution in liver, white adipose tissue (WAT), and feces...

OBJECTIVE: Supplementation of glutathione (GSH) may be a positive strategy to improve the endogenous antioxidant defense required to counteract many acute and chronic diseases. However, the efficacy of GSH treatment seems to be closely related to type of administration, degree of absorption, and increase of its concentrations. The aim of this study was to test a new sublingual formulation of L-GSH, which enters directly the systemic circulation, to assess its efficacy on circulating biochemical markers of hepatic metabolism, lipid profile, and oxidative stress and on peripheral vascular function compared with placebo in patients with cardiovascular risk factors (CVRF)...

OBJECTIVES: One of every four pregnant women in Chile is obese. Gestational obesity is associated with maternal metabolic complications in pregnancy (e.g., gestational diabetes, preeclampsia), but to our knowledge, there is little evidence on relationships with future metabolic risk. The aim of this study was to evaluate the association between prepregnancy obesity (prepregnancy body mass index ≥30 kg/m(2)) or excessive gestational weight gain (GWG; according to the 2009 recommendations from the Institute of Medicine), and maternal metabolic complications 10 y postpartum in premenopausal Chilean women...

OBJECTIVE: Assumptions have linked orange juice (OJ) consumption with weight gain and adverse effects on health due to its sugar content; however, epidemiologic studies have not shown increased risk for overweight or obesity with the consumption of 100% OJ. The aim of this study was to verify whether the combination of a reduced-calorie diet (RCD) and 100% OJ contribute to weight loss, promote changes in glucose and lipid metabolism, and improve diet quality in obese individuals. METHODS: A randomized controlled trial with 78 obese patients (age 36 ± 1 y, body mass index [BMI] 33 ± 3 kg/m(2)) were enrolled in two groups: Individuals in the OJ group submitted to an RCD that included OJ (500 mL/d), and individuals in the control group submitted to an RCD without OJ...

Carotid plaque is a good surrogate endpoint for assessing arterial atherosclerosis, and atherosclerosis is a reliable predictor of cardiovascular diseases. However, the effect of body mass index on carotid plaque is unknown. Therefore, we aimed to explore the association between body mass index and carotid plaque in a low-income Chinese population. Residents aged ≥45 years and free of stroke and cardiovascular diseases were enrolled and divided into four groups based on body mass index. B-mode ultrasonography was performed to measure carotid plaque...

Enhanced bioactive anti-oxidant formulations are critical for treatment of inflammatory diseases, such as atherosclerosis. A hallmark of early atherosclerosis is the uptake of oxidized low density lipoprotein (oxLDL) by macrophages, which results in foam cell and plaque formation in the arterial wall. The hypolipidemic, anti-inflammatory, and antioxidative properties of polyphenol compounds make them attractive targets for treatment of atherosclerosis. However, high concentrations of antioxidants can reverse their anti-atheroprotective properties and cause oxidative stress within the artery...

Scavenger receptor class B type 1(SR-B1) and low density lipoprotein receptor (LDLR) play vital roles in cholesterol homeostasis. Previous studies indicated a strong link between cholesterol and adipose tissue (AT). In this study, adult male SR-B1 and LDLR double knockout (DKO) mice were fed with high fat diet (HFD) for 3 months. Interestingly, we found severe loss of AT in DKO mice fed with HFD. To reverse the AT loss in DKO mice, 1% probucol was added in HFD. In DKO mice on HFD, plasma total cholesterol (TC) and free cholesterol (FC) levels were increased 6 and 15 folds respectively compared with wild type (WT) mice...

Switches in sphingolipid metabolism have recently been associated with oncogenic transformation, and a role for the low-density lipoprotein receptor-related protein 1 (LRP1) in sphingosine-1-phosphate (S1P) proangiogenic signaling inferred. S1P signaling crosstalk with LRP1 in brain microvascular endothelial cells (HBMEC) is however unclear. Transient in vitro siLRP1 gene silencing was compared to stable shLRP1 knockdown. We observed decreased expression of CCAAT/enhancer binding protein β (C/EBPβ), a transcription factor for which multiple binding sites are found within the promoter sequences of all five S1P receptor members, upon stable but not transient LRP1 repression...

Cholesterol accumulation in the liver is an early event in nonalcoholic fatty liver disease (NAFLD). Here, we demonstrate that E2F1 plays a crucial role in maintaining cellular cholesterol homeostasis by regulating cholesterol uptake via proprotein convertase subtilisin/kexin 9 (PCSK9), an enzyme that promotes low-density lipoprotein receptor (LDLR) degradation upon activation. E2f1-/- mice display reduced total plasma cholesterol levels and increased cholesterol content in the liver. In this study, we show that E2f1 deletion in cellular and mouse models leads to a marked decrease in Pcsk9 expression and an increase in LDLR expression...

Hepatitis C virus (HCV) exists as a lipoprotein-virus hybrid lipoviroparticle (LVP). In vitro studies have demonstrated the importance of apolipoproteins in HCV secretion and infectivity leading to the notion that HCV co-opts the secretion of very-low density lipoprotein (VLDL) for its egress. However, our understanding of the mechanisms involved in virus particle assembly and egress, are still elusive. Biogenesis of VLDL particle occurs in the ER followed by subsequent lipidation in the ER and Golgi. Secretion of mature VLDL particles occurs through the Golgi secretory pathway...

Rationale: Observational studies have found shorter leukocyte telomere length to be a risk factor for coronary heart disease (CHD), and more recently the association was suggested to be causal. However, the relationship between telomere length and common metabolic risk factors for CHD is not well understood. Whether these risk factors could explain pathways from telomere length to CHD warrants further attention. Objective: To examine if metabolic risk factors for CHD mediate the causal pathway from short telomere length to increased risk of CHD using a network Mendelian randomization (MR) design...
