BACKGROUND: Accumulating evidence suggests that individual circulating saturated fatty acids (SFAs) are heterogeneous in their associations with cardio-metabolic diseases, but evidence about associations of SFAs with metabolic markers of different pathogenic pathways is limited. We aimed to examine the associations between plasma phospholipid SFAs and the metabolic markers of lipid, hepatic, glycaemic and inflammation pathways. METHODS: We measured nine individual plasma phospholipid SFAs and derived three SFA groups (odd-chain: C15:0 + C17:0, even-chain: C14:0 + C16:0 + C18:0, and very-long-chain: C20:0 + C22:0 + C23:0 + C24:0) in individuals from the subcohort of the European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct case-cohort study across eight European countries...

OBJECTIVE: Adult growth hormone deficiency (AGHD) is associated with cardiometabolic risk factors. Given that cardiovascular disease (CVD) is an important cause of morbidity and mortality in the AGHD population, there is a need for alternative, non-invasive methods of assessing cardiometabolic risk in this population. Chinese visceral adiposity index (CVAI) is a new marker of visceral fat dysfunction that is based on age, body mass index (BMI), waist circumference (WC) and metabolic parameters...

Significant reductions in insulin resistance (IR) can be achieved by either calorie restriction or by the increase of lean mass. However, calorie restriction usually results in significant loss of lean mass. A 6-week randomized controlled feeding trial was conducted to determine if a calorie-restricted, high-protein diet (~125 g protein/day consumed evenly throughout the day) using novel functional foods would be more successful for reducing IR in comparison to a conventional diet (~80 g protein/day) with a similar level of calorie restriction...

AIMS: Osteoporosis-pseudoglioma syndrome (OPPG) is an uncommon autosomal recessive disorder characterized by the rare association of early-onset osteoporosis and severe ocular abnormalities such as persistent fetal vasculature and microphthalmia. Biallelic mutations in the low-density lipoprotein receptor-related protein-5 gene (LRP5) have been associated with OPPG. We present clinical and genetic data of three Mexican OPPG patients, a pair of sibs, and a sporadic case. MATERIALS AND METHODS: Three patients underwent clinical examination, including a complete ophthalmic evaluation...

A computational analysis of the X-ray structure of the low-density lipoprotein receptor-related protein 6 (LRP6) with Dickkopf-1 (DKK1) C-terminal fragment has allowed us to rationally design a small set of decapeptides (1a-e). These compounds behave as agonists of the canonical Wnt pathway in the micromolar range when tested on a dual luciferase Wnt functional assay in glioblastoma cells. Lack of cellular toxicity was assessed for compounds 1c and 1d in human primary osteoblasts isolated from sponge bone tissue (femoral heads or knee of old patients)...

Apolipoprotein (apo)A-I is an organizing scaffold protein that is critical to high-density lipoprotein (HDL) structure and metabolism, probably mediating many of its cardioprotective properties. However, HDL biogenesis is poorly understood, as lipid-free apoA-I has been notoriously resistant to high-resolution structural study. Published models from low-resolution techniques share certain features but vary considerably in shape and secondary structure. To tackle this central issue in lipoprotein biology, we assembled a team of structural biologists specializing in apolipoproteins and set out to build a consensus model of monomeric lipid-free human apoA-I...

The endothelial lining of blood vessels is severely affected in type II diabetes. Yet, there is still a paucity on the use of diabetic endothelial cells for study and assessment of implantable devices targeting vascular disease. This critically impairs our ability to determine appropriate topographical cues to be included in implantable devices that can be used to maintain or improve endothelial cell function in vivo. Here, the functional responses of healthy and diabetic human coronary arterial endothelial cells were studied and observed to differ depending on topography...

Personalized and precise nanomedicines are highly demanded for today's medical needs. Liposomes are ideal candidates for the construction of multifunctional drug delivery systems. In this study, a liposome was used to improve the clinical issues of docetaxel (Doc), a potent antimitotic chemotherapy for prostate cancer (PC). RLT, a low-density lipoprotein receptor (LDLR)-binding peptide, and PEG were conjugated to the liposomes, and gold nanorods (GNRs) were also incorporated into the liposomes. The GNRs/Doc-liposome-RLT (GNRs/DocL-R) was tested in PC-3 cells and in PC-3 tumor-bearing nude mice...

High plasma cholesterol levels are found in several metabolic disorders and their reductions are advocated to reduce risk of atherosclerosis. A way to lower plasma lipids is to curtail lipoprotein production; however, this is associated with steatosis. We previously showed that microRNA-30c (miR-30c) lowers diet-induced hypercholesterolemia and atherosclerosis in C57BL/6J and Apoe-/- mice. Here, we tested miR-30c effect on plasma lipids, transaminases and hepatic lipids in different mouse models. Hepatic delivery of miR-30c to chow fed leptin deficient (ob/ob) and leptin receptor deficient (db/db) hypercholesterolemic and hyperglycemic mice reduced cholesterol in total plasma and VLDL/LDL by ~28% and ~25%, respectively, without affecting triglyceride and glucose levels...

BACKGROUND AND AIMS: Activation of brown adipose tissue (BAT) reduces both hyperlipidemia and atherosclerosis by increasing the uptake of triglyceride-derived fatty acids by BAT, accompanied by formation and clearance of lipoprotein remnants. We tested the hypothesis that the hepatic uptake of lipoprotein remnants generated by BAT activation would be accelerated by concomitant statin treatment, thereby further reducing hypercholesterolemia and atherosclerosis. METHODS: APOE*3-Leiden...

Importance: Current guidelines for atherosclerotic cardiovascular disease focus on high-intensity statins and targeting or using a threshold low-density lipoprotein cholesterol (LDL-C) level of less than 70 mg/dL for the highest-risk patients. Whether further reduction of LDL-C beyond these boundaries would be beneficial is unknown. Objective: To compare outcomes of evolocumab vs placebo in patients with stable atherosclerotic cardiovascular disease and a baseline LDL-C of less than 70 mg/dL and in those receiving background treatment with a maximal-potency statin...

Curcumin is a well‑known phenolic substance and has many pharmacological effects associated with metabolism. However, the exact molecular mechanisms underlying this process have yet to be determined. The Notch pathway is a signal transduction pathway involved in energy metabolism. The present study aimed to investigate the effects of curcumin administration on glucose‑lipid metabolism in rats subjected to a high fat diet, and investigate changes in Notch‑1 signaling. Sprague‑Dawley rats (n=40) were randomly divided into four groups (10 rats/group): Control diet group, high fat diet group, high fat diet plus curcumin low dose group and high fat diet plus curcumin high dose group...

Background: Atherosclerosis occurs as a result of low-density lipoprotein (LDL) deposits oxidation. Endothelial dysfunction is an early process of atherosclerosis. Restoring endothelial lining back to normal by endothelial progenitor cells (EPCs) is critical for slowing or reversing vascular disease progression. Oxidative stress from hydrogen peroxide (H2O2) is increased in dyslipidemia so that antioxidant agent is required to prevent destruction of blood vessels. Objectives: This study aims to report Ganoderma lucidum polysaccharide peptide (PsP) effects in atherogenic process by measuring H2O2 level, IL-10 level, and EPC number in blood serum, and also intima-media thickness of aorta in dyslipidemia Wistar rat model by giving them a hypercholesterol diet (HCD)...
