Soluble urokinase plasminogen activator receptor (suPAR) independently predicts chronic kidney disease (CKD) incidence and progression. Apolipoprotein L1 (APOL1) gene variants G1 and G2, but not the reference allele (G0), are associated with an increased risk of CKD in individuals of recent African ancestry. Here we show in two large, unrelated cohorts that decline in kidney function associated with APOL1 risk variants was dependent on plasma suPAR levels: APOL1-related risk was attenuated in patients with lower suPAR, and strengthened in those with higher suPAR levels...

The secondary structure of apolipoprotein B-100 is studied within the bulk phase and at the air/water interface. In these "in viro" experiments, infrared reflection absorption spectroscopy (IRRAS) study was performed at the air/water interface while circular dichroism (CD) was conducted in the bulk phase. In the bulk phase, the conformational structure containing a significant amount of β-structure, whereas varying amount of α-helix, unordered structures, and β-sheet were observed at the air/water interface depending on the low-density lipoprotein (LDL) film interfacial pressure...

Tanshinone IIA (TSA), a pharmacologically active component isolated from Danshen, may prevent cardiovascular diseases due to its anti-inflammatory, anti-oxidative, and anti-adipogenic effects. Porphyromonas gingivalis, a major periodontal pathogen, may contribute to the progression of atherosclerosis. Here, we studied the effects of TSA on atherosclerosis in ApoE(-/-) mice with P. gingivalis infection. Eight-week-old ApoE(-/-) mice were randomized to (a) phosphate-buffered saline (PBS), (b) P. gingivalis, and (c) P...

Amphipathic α-helices of exchangeable apolipoproteins have shown to play crucial roles in the formation of infectious hepatitis C virus (HCV) particles through the interaction with viral particles. Among the Flaviviridae members, pestivirus and flavivirus possess a viral structural protein Erns or a non-structural protein 1 (NS1) as secretory glycoproteins, respectively, while Hepacivirus including HCV has no secretory glycoprotein. In case of pestivirus replication, the C-terminal long amphipathic α-helices of Erns are important for anchoring to viral membrane...

BACKGROUND: Diabetic peripheral neuropathy (DPN) is a common complication of Type 2 diabetes (T2D). Apart from hyperglycemia, its pathogenesis is poorly understood. Apolipoprotein-CIII (apoC-III) associated with triglyceride metabolism, is a risk factor for cardiovascular disease. Its role in DPN is not well-established. We studied the associations of apoC-III, endothelial function and DPN. METHODS: In patients with T2D, anthropometric data, fasting blood, and urine were collected for biochemistry and urine albumin/creatinine measurements (uACR)...

OBJECTIVE: Cardiovascular disease (CVD) is a major adverse consequence of non-alcoholic fatty liver disease (NAFLD). The association of NAFLD with various apolipoprotein B (apoB) dyslipoproteinemias is unclear. We determined the prevalence of specific apoB dyslipoproteinemias in subjects with suspected NAFLD. METHODS: This study was conducted among 22,865 fasting adults living in the northern part of the Netherlands (Lifelines Cohort Study). Six apoB dyslipoproteinemias were defined using an algorithm derived from apoB, total cholesterol and triglycerides...

OBJECTIVE: Studies evaluating the effect of apolipoprotein E (APOE) on vascular depression are sparse, employ heterogeneous methods, and yield inconsistent results. One possibility is that APOE is a moderator of another predictor such as cerebrovascular burden. This longitudinal study examines the relationships between APOE, cerebrovascular burden, and depressive symptomatology in a large cohort sample from midlife to later life. METHODS: Data include 3,203 participants across 18 years (1993-2011) from the Wisconsin Longitudinal Study (baseline mean age = 53 years)...

A1CF (apobec-1 complementation factor) acts as a component of the apolipoprotein-B messenger RNA editing complex. Previous researches mainly focused on its post-transcriptional cytidine to uridine RNA editing. However, few study reported its role in progression of breast carcinoma cells. Wound healing assay and flow cytometry were applied to detect the migration and apoptosis; western blot, real-time polymerase chain reaction, and dual-luciferase assays were applied to investigate the potential regulation mechanism of A1CF-mediated cell migration and apoptosis...

Apolipoprotein B mRNA-editing enzyme catalytic subunit 3 (APOBEC-3) enzymes are cytidine deaminases that are broadly and constitutively expressed. They are often upregulated during carcinogenesis and candidate genes for causing the major single-base substitution in cancer-associated DNA mutations. Moreover, APOBEC-3s are involved in host innate immunity against many viruses. However, how APOBEC-3 mutational activity is regulated in normal and pathological conditions remains largely unknown. Heat shock protein levels are often elevated in both carcinogenesis and viral infection and are associated with DNA mutations...

Apolipoprotein B (ApoB) is a major protein component of plasma lipoproteins, which have been involved in many important biological processes such as lipid transportation, enzyme activity regulation and receptor recognition. Extensive studies have showed that the expression of the ApoB was regulated at multiple levels. However, the regulation of ApoB expression by microRNAs (miRNAs) still remains unknown. In present studies, miRNAs that interact with ApoB have been predicted in chicken. The targeted relationship between the predicated miRNAs and ApoB was verified through dual luciferase reporter assay in chicken DF1 cells, and the effect of miRNAs on ApoB expression was analyzed in chicken embryo hepatocytes stimulated by 17β-estradiol...

Context: Angiopoietin-like 3 (ANGPTL3) deficiency in plasma due to loss-of-function (LOF) gene mutations causes familial combined hypobetalipoproteinemia (FHBL) type 2 in homozygotes. However, the lipid phenotype in heterozygotes is much milder and does not appear to relate directly to ANGPTL3 levels. Furthermore, the low LDL phenotype in carriers of ANGPTL3 mutations is unexplained. Objective: To determine whether a reduction below a critical threshold in plasma ANGPTL3 levels is a determinant of lipoprotein metabolism in FHBL2, and to study the whether PCSK9 is involved in determining low LDL levels in this condition...

BACKGROUND: Lipoprotein(a) (Lp(a)) is a causal risk factor for a variety of cardiovascular diseases. Apolipoprotein(a) (apo(a)), the distinguishing component of Lp(a), is homologous to plasminogen, suggesting that Lp(a) can interfere with the normal fibrinolytic functions of plasminogen. This has implications for the persistence of fibrin clots in the vasculature and hence to atherothrombotic diseases. A single nucleotide polymorphism (rs3798220) in the gene encoding apo(a) has been reported that results in an Ile to Met substitution in the protease-like domain (I4399M variant)...

Three medium- and long-chain triacylglycerols (MLCT) with different contents of medium-chain fatty acids (MCFA) (10% to 30%, w/w) were prepared and evaluated for their anti-obesity potential in C57BL/6J mice. The group fed with a high fat diet of MLCT containing 30% (w/w) MCFA showed significantly decreased body weight and fat mass (P < 0.05) relative to the control mice fed an obesity-inducing high fat rapeseed oil diet. In addition, serum parameters including triacylglycerols, total cholesterol, glucose, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, apolipoprotein A1 and apolipoprotein B in the treatment group fed with 30% (w/w) MCFA were close to those of mice fed with a low fat rapeseed oil diet, but significantly different (P < 0...

BACKGROUND: Sclerostin is an inhibitor of the wingless-type mouse mammary tumor virus integration site family/β-catenin signalling pathway (WβcSP), which plays an important role in bone metabolism and in vascular biology. It could act protective regarding atherosclerosis development through its effect on WβcSP in vascular cells. Nevertheless, results of studies analyzing association between circulating sclerostin level (CSL) and atherosclerotic diseases (AD) are showing conflicting results...

REVIEW
Hartmut H Glossmann, Oliver M D Lutz
3-Monoiodothyronamine (T1AM), first isolated from rat brain, is reported to be an endogenous, rapidly acting metabolite of thyroxine. One of its numerous effects is the induction of a "torpor-like" state in experimental animals. A critical analysis of T1AM, to serve as an endogenous cryogen, is given. The proposed biosynthetic pathway for formation of T1AM, which includes deiodinases and ornithine decarboxylase in the upper intestinum, is an unusual one. To reach the brain via systemic circulation, enterohepatic recycling and passage through the liver may occur...

BACKGROUND: Previous studies have reported high plasma concentrations of both intestinal apolipoprotein (apo) B-48-containing lipoproteins and PCSK9 in subjects with familial hypercholesterolemia (FH). However, the extent to which LDL receptor deficiency and PCSK9 levels influence plasma apoB-48 concentrations in humans remains to be fully characterized. The objective of the study was to assess the independent association between FH, PCSK9 concentrations and plasma apoB-48 levels in a large cohort of genetically defined FH heterozygotes (HeFH) and homozygotes (HoFH)...
